QUESTION 78
You manage an Azure virtual network that hosts 15 virtual machines (VMs) on a single subnet, which is used for testing a line of business (LOB) application. The application is deployed to a VM named TestWebServiceVM. You need to ensure that TestWebServiceVM always starts by using the same IP address. You need to achieve this goal by using the least amount of administrative effort. What should you do?

A.    Use the Management Portal to configure TestWebServiceVM.
B.    Use RDP to configure TestWebServiceVM.
C.    Run the Set-AzureStaticVNetIP PowerShell cmdlet.
D.    Run the Get-AzureReservedIP PowerShell cmdlet.

Answer: C
Explanation:
Specify a static internal IP for a previously created VM
If you want to set a static IP address for a VM that you previously created, you can do so by using the following cmdlets. If you already set an IP address for the VM and you want to change it to a different IP address, you’ll need to remove the existing static IP address before running these cmdlets. See the instructions below to remove a static IP. For this procedure, you’ll use the Update-AzureVM cmdlet. The Update-AzureVM cmdlet restarts the VM as part of the update process. The DIP that you specify will be assigned after the VM restarts. In this example, we set the IP address for VM2, which is located in cloud service StaticDemo.
Get-AzureVM -ServiceName StaticDemo -Name VM2 | Set-AzureStaticVNetIP -IPAddress 192.168.4.7 | Update-AzureVM

QUESTION 85
Your company network has two physical locations configured in a geo-clustered environment. You create a Blob storage account in Azure that contains all the data associated with your company. You need to ensure that the data remains available in the event of a site outage. Which storage option should you enable?

A.    Locally redundant storage
B.    Geo-redundant storage
C.    Zone-redundant storage
D.    Read-only geo-redundant storage

Answer: D
Explanation:
Introducing Read-only Access to Geo Redundant Storage (RA-GRS): RA-GRS allows you to have higher read availability for your storage account by providing “read only” access to the data replicated to the secondary location. Once you enable this feature, the secondary location may be used to achieve higher availability in the event the data is not available in the primary region. This is an “opt-in” feature which requires the storage account be geo-replicated.

B.    Add-AzureVhd
C.    Add-AzureVMImage
D.    Update-AzureDisk
E.    Add-AzureDataDisk

Answer: C
Explanation:
The Add-AzureVMImage cmdlet adds an operating system image to the image repository. The image should be a generalized operating system image, using either Sysprep for Windows or, for Linux, using the appropriate tool for the distribution.
Example:
This example adds an operating system image to the repository.
Windows PowerShell

For example, the Graph API supports the following common operations for a user object:
/ Create a new user in a directory
/ Get a user’s detailed properties, such as their groups
/ Update a user’s properties, such as their location and phone number, or change their password
/ Check a user’s group membership for role-based access
/ Disable a user’s account or delete it entirely

Your company is launching a public website that allows users to stream videos. You upload multiple video files to an Azure storage container. You need to give anonymous users read access to all of the video files in the storage container. What should you do?

A.    Edit each blob’s metadata and set the access policy to Public Blob.
B.    Edit the container metadata and set the access policy to Public Container.
C.    Move the files into a container sub-directory and set the directory access level to Public Blob.
D.    Edit the container metadata and set the access policy to Public Blob.

Your network environment includes remote employees. You need to create a secure connection for the remote employees who require access to your Azure virtual network. What should you do?

A.    Deploy Windows Server 2012 RRAS.
B.    Configure a point-to-site VPN.
C.    Configure an ExpressRoute.
D.    Configure a site-to-site VPN.

Answer: B
Explanation:
New Point-To-Site Connectivity
With today’s release we’ve added an awesome new feature that allows you to setup VPN connections between individual computers and a Windows Azure virtual network without the need for a VPN device. We call this feature Point-to-Site Virtual Private Networking. This feature greatly simplifies setting up secure connections between Windows Azure and client machines, whether from your office environment or from remote locations. It is especially useful for developers who want to connect to a Windows Azure Virtual Network (and to the individual virtual machines within it) from either behind their corporate firewall or a remote location. Because it is point-to-site they do not need their IT staff to perform any activities to enable it, and no VPN hardware needs to be installed or configured. Instead you can just use the built-in Windows VPN client to tunnel to your Virtual Network in Windows Azure.

You want to ensure secure communications between the branch offices and the internal VMs and network. You need to create a site-to-site VPN connection. What are two possible ways to achieve this goal? Each correct answer presents a complete solution.

A.    a private IPv4 IP address and a compatible VPN device
B.    a private IPv4 IP address and a RRAS running on Windows Server 2012
C.    a public-facing IPv4 IP address and a compatible VPN device
D.    a public-facing IPv4 IP address and a RRAS running on Windows Server 2012

Case Study 1 – Olympic Marathon (QUESTION 1 – QUESTION 12)
Background
You are developing an ASP.NET MVC application in Visual Studio 2012 that will be used by Olympic marathon runners to log data about training runs.
Business Requirements
The application stores date, distance, and duration information about a user’s training runs. The user can view, insert, edit, and delete records. The application must be optimized for accessibility. All times must be displayed in the user’s local time.
Technical Requirements
Data Access:
Database access is handled by a public class named RunnerLog.DataAccess.RunnerLogDb. All data retrieval must be done by HTTP GET and all data updates must be done by HTTP POST.
Layout:
All pages in the application use a master layout file named \Views\Shared\_Layout.cshtml.
Models:
The application uses the \Models\LogModel.cs model.
Views:
All views in the application use the Razor view engine. Four views located in \Views\RunLog are named:

– _CalculatePace.cshtml
– EditLog.cshtml
– GetLog.cshtml
– InsertLog.cshtml
The application also contains a \Views\Home\Index.cshtml view.
Controllers:
The application contains a \Controllers\RunLogController.cs controller.
Images:
A stopwatch.png image is located in the \Images folder.
Videos:
A map of a runner’s path is available when a user views a run log. The map is implemented as an Adobe Flash application and video. The browser should display the video natively if possible, using H264, Ogg, or WebM formats, in that order. If the video cannot be displayed, then the Flash application should be used.
Security:
You have the following security requirements:
– The application is configured to use forms authentication.
– Users must be logged on to insert runner data.
– Users must be members of the Admin role to edit or delete runner data.
– There are no security requirements for viewing runner data.
– You need to protect the application against cross-site request forgery.
– Passwords are hashed by using the SHA1 algorithm.
RunnerLog.Providers.RunLogRoleProvider.es contains a custom role provider. Relevant portions of the application files follow. (Line numbers are included for reference only.)

You are designing a Windows Communication Foundation (WCF) service that uses the Product class. You need to update the class to meet the storage requirement. What should you do? (Each correct answer presents part of the solution. Choose all that apply.)

A.    Mark the Product class with the DataContract attribute.
B.    Mark the public members of the Product class with the DataContractFormat attribute.
C.    Mark the Product class with the CollectionDataContract attribute.
D.    Mark the public members of the Product class with the DataMember attribute.

Answer: AD
Explanation:
So as of .NET 3.5 SP1, you don’t have to add data contract or data member attributes anymore-if you don’t then the data contract serializer will serialize all public properties on your class, just like the XML serializer would. HOWEVER: by not adding those attributes, you lose a lot of useful capabilities:
– without [DataContract], you cannot define an XML namespace for your data to live in
– without [DataMember], you cannot serialize non-public properties or fields
– without [DataMember], you cannot define an order of serialization (Order=) and the DCS will serialize all properties alphabetically
– without [DataMember], you cannot define a different name for your property (Name=)
– without [DataMember], you cannot define things like IsRequired= or other useful attributes
– without [DataMember], you cannot leave out certain public properties – all public properties will be serialized by the DCS

Case Study 3 – Video Transcoding Service (QUESTION 28 – QUESTION 36)
Background
You are developing a video transcoding service. This service is used by customers to upload video files, convert video to other formats, and view the converted files. This service is used by customers all over the world.
Business Requirements
The user-facing portion of the application is an ASP.NET MVC application. It provides an interface for administrators to upload video and schedule transcoding. It also enables administrators and users to download the transcoded videos. When videos are uploaded, they are populated with metadata used to identify the video. The video metadata is gathered by only one system when the video upload is complete. Customers require support for Microsoft Internet Explorer 7 and later. The application contains a header that is visible on every page. If the logged-on user is an administrator, then the header will contain links to administrative functions. This information is read from a cookie that is set on the server. The administrative links must not be present if an error condition is present.
Technical Requirements
User Experience:
– The front-end web application enables a user to view a list of videos.
– The main view of the application is the web page that displays the list of videos.
– HTML elements other than the list of videos are changed with every request requiring the page to reload.
Compatibility:
– Some customers use browsers that do not support the HTTP DELETE verb.
– These browsers send a POST request with an HTTP header of X-Delete when the intended action is to delete.
Transcoding:
– The video transcoding occurs on a set of Windows Azure worker roles.
– The transcoding is performed by a third-party command line tool named transcode.exe. When the tool is installed, an Environment variable named transcode contains the path to the utility.
– A variable named license contains the license key. The license for the transcoding utility requires that it be unregistered when it is not in use.
– The transcoding utility requires a significant amount of resources. A maximum of 10 instances of the utility can be running at any one time. If an instance of the role cannot process an additional video, it must not prevent any other roles from processing that video.
– The utility logs errors to a Logs directory under the utilities path.
– A local Azure directory resource named perf is used to capture performance data.
Development:
– Developers must use Microsoft Remote Desktop Protocol (RDP) to view errors generated by the transcode.exe utility.
– An x509 certificate has been created and distributed to the developers for this purpose.
– Developers must be able to use only RDP and not any other administrative functions.
Application Structure

Case Study 4 – Consolidated Messenger (QUESTION 37 – QUESTION 47)
Background
Business Scenario
You are the lead architect, developer, and web administrator of SharePoint 2013 for your company, Consolidated Messenger. Consolidated Messenger is a national company with hundreds of franchises. Consolidated Messenger focuses on bicycle-based courier services in metropolitan areas. Consolidated Messenger sells franchises to franchisees. Franchisees have three user types:

Technical Scenario
When a franchisee purchases a franchise, they are provided with:
– Access to Consolidated Messenger’s SharePoint 2013 multi-tenant farm located at https://sp.consolidatedmessenger.com
– Access to a Customers list in the Corporate site collection, named CorporateSiteCollection, which includes a list of all Customers across all franchisees
– A single site collection for each franchisee, named FranchiseeSiteCollection
– An unlimited number of customer subsites for each franchisee
– Consolidated Messenger has funded the creation of three apps

Solution Architecture

Site Collection Structure

SharePoint Farm Design
My Sites are not created for each Franchisee unless they are requested.
Business Requirements

Technical Requirements
Each Franchise site collection must include a SharePoint document library to store CSV files.
FranchiseMonitor App
Application Design
Franchise employees use Microsoft Excel 2013 to create a list of pick-up and drop-off locations for each bicycle courier for each day. The spreadsheet is named Appointments.csv.
Business Requirements
The FranchiseMonitor app must allow a Franchise employee to upload Appointments.csv to a SharePoint document library in each Franchisee site collection, and send Appointments.csv to the CloudManager app.
Technical Requirements
– The FranchiseMonitor app must display the courier’s location on the bicycle courier’s microfeed on the SharePoint farm if the courier has remained stationary for more than three minutes.
– The FranchiseMonitor app must be listed on the Site Contents page of the host web.
– The FranchiseMonitor app must use claims-based authentication, once launched, to authenticate the franchisee against an API provided by Margie’s Travel.
– The FranchiseMonitor app must be deployed to all site collections by the SharePoint administrator.
– The FranchiseMonitor app must be immediately available to be installed on websites within the tenancy on a website-by-website basis to any tenant contained in the SharePoint farm.
– The FranchiseMonitor app must be able to create lists within SharePoint to store records of the CSV files so that they may be sent to the CloudManager app.
CourierMobile App
Application Design
– Each bicycle courier for each franchise is provided a Microsoft Surface Pro device with LTE. Most bicycle couriers do not return their Microsoft Surface Pro devices back to their franchise locations nightly.
– The CourierMobile app runs on the bicycle courier’s Microsoft Surface Pro device.
– Margie’s Travel provides an API to enable external developers to authenticate by using OAuth and claims-based authentication. Many couriers are members of Margie’s Travel.
– The CourierMobile app receives Microsoft Outlook appointments and Outlook appointment cancellations from the CloudManager app. The appointments include the address of the location for pick-up or drop-off.
Business Requirements
– The CourierMobile app must display a Bing map to display route data when Outlook appointments or appointment cancellations are received.
– The CourierMobile app must capture the location of the Microsoft Surface Pro device on a regular interval. This data must be captured regardless of whether the device has connectivity.
– The CourierMobile app must be able to connect to the SharePoint Customers list and verify whether the account belongs to the franchisee to avoid pickups or deliveries to customers that do not belongs to the franchisee. When the CourierMobile add accesses the Customers list, it must only read its contents with the minimum permissions necessary.
Technical Requirements
– The CourierMobile app must provide the ability to authenticate by using the courier’s Microsoft account or the Margie’s Travel API.
– The CourierMobile app must include a custom sign-in page that includes branding from Consolidated Messenger and Margie’s Travel, based on the authentication provider selected by the user.
– The CourierMobile app must be able to capture more than 30 million data points of location data daily as they occur and upload the location data to the cloud when connected to the Internet.
CloudManager App
Application Design
CloudManager processes two sets of data:
– Updates to the list of appointments received from the FranchiseMonitor app
– Geo-location data received from the CourierMobile app
Business Requirements
The CloudManager app must implement business logic that parses Appointments.csv and geo-location data and sends Appointments or Appointment cancellations to the CourierMobile app.
Technical Requirements
– The CloudManager app must elastically scale to capture courier location data as the number of bicycle couriers increases or decreases.
– The CloudManager app must process bicycle courier location data from a data store capable of storing more than 30 million items.

Case Study 7 – Litware Inc (QUESTION 64 – QUESTION 72)
Background
You are a SharePoint developer working for Litware Inc., a large bicycle manufacturing company. Litware runs an intranet that is based on SharePoint Server 2010, side-by-side a collaboration space for various departments. The IT department for Litware is migrating a SharePoint 2010 environment to a new SharePoint 2013 farm. Some collaboration site collections are already migrated, including a Marketing site collection.
Business Requirements
Intranet
Litware is redefining its brand identity. It is essential that the new intranet supports a wide variety of mobile devices, platforms, and browsers. Some of the content must be migrated from the old intranet during the implementation. The redesigned intranet must be extensible. The solution must be designed with the changes in the underlying technology in mind. A marketing company named Graphic Design Institute provides documents and guidelines for the new design for Litware’s intranet.
Collaboration
Litware has the following collaboration requirements:
– The collaboration space must include a start page containing information about site owners, contact data, and statistics on site usage. This information must be available for each collaboration space, directly after its creation.
– The project must be delivered in multiple phases.
– The solution must support changes and updates on the structure and functionality of the collaboration spaces.
Marketing collaboration space
Auditors must be able to create reports about the documents the Marketing team produces. Initial reports should show document distribution over projects and information about the most active documents, the top inactive documents, and the most active users. Additional reports will be added over time.
Technical Requirements
Publishing Design for the Intranet
Litware will use the following web application for the intranet: https://intranet.litwareinc.com. The publishing site design is delivered as a set of HTML files (litwarepublishing.html), CSS (Litwarepublishing.css), and image files from the marketing company. A design package must be created for easier deployment over various platforms. During the creation and application of the design package to the publishing site, SharePoint 2013 out-of-the-box capabilities must be used as much as possible to ensure simple design changes and to simplify the upgrade procedures. The publishing site must support rendering on a number of devices, starting with Windows Phone. Apart from being deployed on all existing publishing sites, the design package must be automatically applied each time a publishing site is created. A search box must be available on all publishing sites.
Collaboration
Litware will use two additional web applications for the collaboration:
– Collaboration 1: https://collab1.litwareinc.com
– Collaboration 2: https://collab2.litwareinc.com
Most of the features contained within the Team Site template are sufficient; however, a few additions to the template must be made to support the business requirements. In order to achieve this and ensure maximum portability, a web template based on the Team Site definition must be created. A three-state workflow must be used to manage business processes. A customized default home page must be deployed by using a site feature.
Feature IDs:
– Three-state workflow: FDE5D850-671E-4143-950A-87B473922DC7
– Litware Web Artifacts: DBF80SAB-03D9-43DC-9154-52D6AC54689F
The project must be implemented in phases, so a solution must be developed to support upgrade procedures. As soon as the package containing the web template Litware.Intranet.Templates.wsp is deployed, the Litware Team Site template must be available for use in all site collections. In order to make the solution as extensible as possible, all core functionality should be moved to the separate package Litware.Intranet.Core.wsp. Deployment of the package containing the Litware web templates Litware.Intranet.Templates.wsp must be prevented if the core package is not deployed in order to prevent deployment errors and eventually damage on the site structure itself.
Litware.Intranet.Templates contains two features:
– The LitwareWebTemplateFeature feature contains the Litware Team Site web template. Templates with this title must be available in the group Litware in the template selection.
– The LitwareWebArtifacts hidden feature contains code required to run after the provisioning is completed.
The LitwareWebArtifacts feature can be activated only if the LitwareWebTemplateFeature feature is activated as well.
Marketing site collection
An existing marketing collaboration site located in a web application named Collaboration 1 is located at https://collabl.litwareinc.com/sites/marketing. Collaboration 1 contains a document library with approximately 9000 documents for approximately 200 projects. The largest project contains 120 files. Documents are assigned to appropriate projects by using the Projects field. The farm uses the default throttle settings. Users report that they cannot sort documents in the marketing collaboration site. Auditors have access to the page that provides statistics on Marketing documents. This page contains a report on document distribution over projects and information about the most active documents, the top inactive documents, and the most active users. Processing the queries can result in working with huge result sets. You must ensure that the information on this page is always available and that the queries are not throttled. The relevant code segment is available in the code sections area (MarketingAudit.ascx.es).
Application Structure
Relevant portions of the app files are shown below. (Line numbers in the code segments are included for reference only and include a two-letter prefix that denotes the specific file to which they belong.)

QUESTION 89
You need to resolve the image loading issue. What should you do? (Each correct answer presents a part of the solution. Choose all that apply.)

A.    Set the size of the site collection object cache to at least 100 MB.
B.    Enable the binary large object (BLOB) cache on each front-end web server.
C.    Activate the Content Organizer site feature.
D.    Enable authenticated cache profiles for the site output cache.
E.    Enable publishing features for the site collection.
F.    Set the default device channel to the active channel.

Answer: AB
Explanation:
A: The object cache is used internally to optimize page rendering by storing properties of sites, page layouts, and pages. The object cache reduces the amount of traffic between the Web server and a SQL database. This results in higher throughput of rendered pages, thereby increasing the number of pages that can be delivered to clients.
B: SharePoint Server 2013 provides a disk-based cache that stores files that are used by web pages to help them load quickly in the browser, and reduces the load on the database server when it uses those files. These files are known as binary large objects (BLOBs), and the cache is known as the BLOB cache. The BLOB cache is stored directly on the hard disk drive of a front-end web server computer.
– When using Image Rendition you will have to enable BLOBCache to improve performance
– By using Device Channel Renditions you can create smaller image sizes designed specifically for mobile use. This allows the mobile user to browse the smaller version, increasing the overall performance for the device they are using. Image Rendition enables you to have large files stored within your website along with smaller scaled variations for mobile users.
When using Image Rendition you will have to enable BLOBCache to improve performance
From scenario:
– Some employees report that the home page loads slowly. You investigate the issue and find out that the size of some images is very large. You must enable image renditions on the intranet site collection.

A.    T4 text templates and code generation
B.    Stub types
C.    Shim types
D.    Hard-coded implementation

Answer: C
Explanation:
http://msdn.microsoft.com/en-us/library/hh549176.aspx
Shim types are one of two technologies that the Microsoft Fakes Framework uses to let you easily isolate components under test from the environment. Shims divert calls to specific methods to code that you write as part of your test. Many methods return different results dependent on external conditions, but a shim is under the control of your test and can return consistent results at every call. This makes your tests much easier to write.

QUESTION 4
You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to create a Windows Communication Foundation (WCF) Data Services service. You discover that when an application submits a PUT or DELETE request to the Data Services service, it receives an error. You need to ensure that the application can access the service. Which header and request type should you use in the application?

A.    an X-HTTP-Method header as part of a POST request
B.    an X-HTTP-Method header as part of a GET request
C.    an HTTP ContentType header as part of a POST request
D.    an HTTP ContentType header as part of a GET request

Answer: A
Explanation:
The X-HTTP-Method header can be added to a POST request that signals that the server MUST process the request not as a POST, but as if the HTTP verb specified as the value of the header was used as the method on the HTTP request’s request line, as specified in [RFC2616] section 5.1. This technique is often referred to as “verb tunneling”. This header is only valid when on HTTP POST requests.

QUESTION 5
You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to create an application. The application connects to a Microsoft SQL Server 2008 database. You create classes by using LINQ to SQL based on the records shown in the exhibit. You need to create a LINQ query to retrieve a list of objects that contains the OrderID and CustomerID properties. You need to retrieve the total price amount of each Order record. What are two possible ways to achieve this goal? (Each correct answer presents a complete solution. Choose two.)

A.    from details in dataContext.Order_Detail
group details by details.OrderID
into g
join order in dataContext.Orders on g.Key equals order.OrderID
select new
{
OrderID = order.OrderID,
CustomerID = order.CustomerID,
TotalAmount = g.Sum(od => od.UnitPrice * od.Quantity)
}
B.    dataContext.Order_Detail.GroupJoin(dataContext.Orders,
d => d.OrderID, o => o.OrderID,
(dts, ord) => new {
OrderID = dts.OrderID,
CustomerID = dts.Order.CustomerID,
TotalAmount = dts.UnitPrice * dts.Quantity
})
C.    from order in dataContext.Orders
group order by order.OrderID into g
join details in dataContext.Order_Detail on g.Key equals
details.OrderID select new
{
OrderID = details.OrderID,
CustomerID = details.Order.CustomerID,
TotalAmount = details.UnitPrice * details.Quantity
}
D.    dataContext.Orders.GroupJoin(dataContext.Order_Detail,
o => o.OrderID,
d => d.OrderID,
(ord, dts) => new {
OrderID = ord.OrderID,
CustomerID = ord.CustomerID,
TotalAmount = dts.Sum(od => od.UnitPrice * od.Quantity)
})

Answer: AD
Explanation:
Alterantive A. This is an Object Query. It looks at the Order Details EntitySet and creating a group g based on OrderID.
– The group g is then joined with Orders EntitySet based on g.Key = OrderID
– For each matching records a new dynamic object containing OrderID, CustomerID and TotalAmount is created
– The dynamic records are the results returned in an INumerable Object, for later processing
Alterantive D. This is an Object Query. The GroupJoin method is used to join Orders to OrderDetails.
Parameters for GroupJoin:
1. An Order_Details EntitySet
2. Order o (from the Orders in the Orders Entity Set, picking up Order_id from both Entity Sets)
3. Order_ID from the first Order_Details record from the OD EnitySet
4. Lamda Expression passing ord and dts (ord=o, dts=d)
The body of the Lamda Expression is working out the total and Returning a Dynamic object as in A.

QUESTION 6
You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to create an application. The application connects to a Microsoft SQL Server database. You use the following SQL statement to retrieve an instance of a DataSet object named ds:
SELECT CustomerID, CompanyName, ContactName, Address, City
FROM dbo.Customers
You need to query the DataSet object to retrieve only the rows where the ContactName field is not NULL. Which code segment should you use?

A.    from row in ds.Tables[0].AsEnumerable()
where (string)row[“ContactName”] != null
select row;
B.    from row in ds.Tables[0].AsEnumerable()
where row.Field<string>(“ContactName”) != null
select row;
C.    from row in ds.Tables[0].AsEnumerable()
where !row.IsNull((string)row[“ContactName”])
select row;
D.    from row in ds.Tables[0].AsEnumerable()
where !Convert.IsDBNull(row.Field<string>(“ContactName”))
select row;

Answer: B
Explanation:
Field<T>(DataRow, String) Provides strongly-typed access to each of the column values in the specified row. The Field method also supports nullable types.

QUESTION 8
You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to create an application. The application connects to a Microsoft SQL Server database. You use Entity SQL to retrieve data from the database. You need to enable query plan caching. Which object should you use?

A.    EntityCommand
B.    EntityConnection
C.    EntityTransaction
D.    EntityDataReader

Answer: A
Explanation:
Whenever an attempt to execute a query is made, the query pipeline looks up its query plan cache to see whether the exact query is already compiled and available.
If so, it reuses the cached plan rather than building a new one.
If a match is not found in the query plan cache, the query is compiled and cached.
A query is identified by its Entity SQL text and parameter collection (names and types).
All text comparisons are case-sensitive.
Query plan caching is configurable through the EntityCommand.
To enable or disable query plan caching through System.Data.EntityClient.EntityCommand. EnablePlanCaching, set this property to true or false.
Disabling plan caching for individual dynamic queries that are unlikely to be used more then once improves performance.
You can enable query plan caching through EnablePlanCaching.

Answer: C
Explanation:
HTTP Actions
OData supports the following HTTP actions to perform create, read, update, and delete operations on the entity data that the addressed resource represents:
HTTP GET-This is the default action when a resource is accessed from a browser. No payload is supplied in the request message, and a response method with a payload that contains the requested data is returned.
HTTP POST-Inserts new entity data into the supplied resource. Data to be inserted is supplied in the payload of the request message.
The payload of the response message contains the data for the newly created entity.
This includes any autogenerated key values.
The header also contains the URI that addresses the new entity resource. HTTP DELETE-Deletes the entity data that the specified resource represents. A payload is not present in the request or response messages. HTTP PUT – Replaces existing entity data at the requested resource with new data that is supplied in the payload of the request message.
HTTP MERGE-Because of inefficiencies in executing a delete followed by an insert in the data source just to change entity data, OData introduces a new HTTP MERGE action. The payload of the request message contains the properties that must be changed on the addressed entity resource. Because HTTP MERGE is not defined in the HTTP specification, it may require additional processing to route a HTTP MERGE request through non-OData aware servers.

VB Scenario
Background
You are updating an existing Microsoft .NET Framework 4 application that includes a data layer built with ADO.NET Entity Framework 4. The application communicates with a Microsoft SQL Server 2008 instance named INST01 on a server named SQL01. The application stores data in a database named Contoso in the INST01 instance. You need to update the existing technology and develop new functionality by using Microsoft Visual Studio 2010.
Application and Database Storage
The application tracks bicycle parts as they pass through a factory. Parts are represented by the abstract Part entity and its associated partial classes. Each part has a name stored in the Name field and a unique identifier stored in the Id field.
Parts are either component s (represented by the Component class) such as chains, wheels, and frames, or finished product s (represented by the Product class) such as completed bicycles. The Component class and the Product class derive from the Part class and may contain additional class-specific properties.
Parts may have a color (represented by the Color class), but not all parts have a color, Parts may be composed of other parts, and those parts may in turn be composed of other parts ; any p art represents a tree of the parts that are used to build it, The lowest level of the tree consists of c omponents that do not contain other components.
A product is a p art that has been completed and is ready to leave the factory. A p roduct typically consists of many c omponents (forming a tree of child p arts) but can also be constructed by combining other p roducts and/or c omponents to form a bundled p roduct, such as a bicycle and a helmet that are sold together.
Components and products are stored in a database table named Parts by using a table-per-hierarchy (TPH) mapping. Components have a null ProductType field and a non-null PartType field. Products have a non-null ProductType field and a null PartType field.
The following diagram illustrates the complete Entity data model diagram (EDMX diagram).

QUESTION 17
You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to create a multi-tier application. You use Microsoft ADO.NET Entity Data Model (EDM) to model entities. The model contains entities named SalesOrderHeader and SalesOrderDetail. For performance considerations in querying SalesOrderHeader, you detach SalesOrderDetail entities from ObjectContext. You need to ensure that changes made to existing SalesOrderDetail entities updated in other areas of your application are persisted to the database. Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

A.    Re-attach the SalesOrderDetail entities.
B.    Set the MergeOption of SalesOrderDetail to MergeOptions.OverwriteChanges.
C.    Set the MergeOption of SalesOrderDetail to MergeOptions.NoTracking.
D.    Call ObjectContext.ApplyCurrentValue.
E.    Call ObjectContext.ApplyOriginalValue.

Answer: AE
Explanation:
ApplyCurrentValues(Of TEntity) Copies the scalar values from the supplied object into the object in the ObjectContext that has the same key.
The ApplyCurrentValues<TEntity> method is used to apply changes that were made to objects outside the ObjectContext, such as detached objects that are received by a Web service. The method copies the scalar values from the supplied object into the object in the ObjectContext that has the same key. You can use the EntityKey of the detached object to retrieve an instance of this object from the data source. Any values that differ from the original values of the object are marked as modified.
Note, the method does not apply the current values to the related objects of currentEntity. ApplyOriginalValues(Of TEntity) Copies the scalar values from the supplied object into set of original values for the object in the ObjectContext that has the same key.
The ApplyOriginalValues<TEntity> method is used to apply changes that were made to objects outside the ObjectContext, such as detached objects that are received by a Web service.

QUESTION 23
You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to create a Microsoft ASP.NET application. The application connects to a Microsoft SQL Server database. The application is hosted on a Web server along with other applications. You need to secure the transmission of data between the application and the database. You need to achieve this goal without affecting other applications. What should you do?

A.    Encrypt the connection string.
B.    Use encryption to store sensitive data in the database.
C.    Use Secure Sockets Layer (SSL) to establish connections to the database.
D.    Use Internet Protocol Security (IPSec) to secure the communication channel.

Answer: C
Explanation:
SSL is an established standard for ensuring secure HTTP transactions.
SSL provides a mechanism to perform up to 128-bit encryption on all transactions between the client and server.
It enables the client to verify that the server belongs to a trusted entity through the use of server certificates.
It also enables the server to confirm the identity of the client with client certificates.
Each of these issues–encryption, server identity, and client identity–are negotiated in the SSL handshake that occurs when a client first requests a resource from a Secure Hypertext Transfer Protocol (HTTPS) server. Essentially, the client and server each present a list of required and preferred settings.
If a common set of requirements can be agreed upon and met, an SSL connection is established.
Internet Protocol Security (IPsec) is a set of security protocols used to transfer IP packets confidentially across the Internet.
IPsec is mandatory for all IPv6 implementations and optional for IPv4.
An IPsec policy is a set of rules that determine which type of IP traffic needs to be secured using IPsec and how to secure that traffic.
Only one IPsec policy is active on a computer at one time.

TransactionManager.Reenlist() Reenlists a durable participant in a transaction.
A resource manager facilitates resolution of durable enlistments in a transaction by reenlisting the transaction participant after resource failure.
Transaction.EnlistVolatile() Enlists a volatile resource manager to participate in a transaction. Volatile resource managers cannot recovery from failure to complete a transaction in which they were participating.
Transaction.EnlistDurable() Enlists a durable resource manager to participate in a transaction.
TransactionManager.RecoveryComplete() Notifies the transaction manager that a resource manager recovering from failure has finished reenlisting in all unresolved transactions.
All durable resource managers should do recovery when they first start up by calling the Reenlist method for each outstanding transaction. Only when all of the reenlistments are done should the resource manager call RecoveryComplete.

QUESTION 36
You are a tasked with performing a code review. The business rule is the following:
– If INSERTs into the first table succeed, then INSERT into the second table.
– However, if the INSERTs into the second table fail, roll back the inserts in the second table but do not roll back the inserts in the first table.
– Although this can also be done by way of regular transactions, It needs to be performed using TransactionScope objects.
Whis code would fit this business rule?

A.    try
{
using (TransactionScope scope1 = new TransactionScope
(TransactionScopeOption)
{
….
Try
{
…..
using (TransactionScope scope2 = new TransactionScope
(TransactionScopeOption))

Answer: D
Explanation:
Required A transaction is required by the scope. It uses an ambient transaction if one already exists. Otherwise, it creates a new transaction before entering the scope. This is the default value. RequiresNew A new transaction is always created for the scope. Suppress The ambient transaction context is suppressed when creating the scope. All operations within the scope are done without an ambient transaction context.

QUESTION 44
You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to create an application. The application connects to a Microsoft SQL Server 2008 database. The application uses a Microsoft ADO.NET SQL Server managed provider.
“Data Source=myServerAddress; Initial Catalog=myDataBase; User Id=myUsername; Password=secret;”
You need to ensure that the database credentials are secure. Which is the correct Property to insert?

A.    Integrated Security=SSPI;
B.    Persist Security Info=true;
C.    Persist Security Info=false;
D.    Integrated Security=false;

Answer: C
Explanation:
Persist Security Info
Default: ‘false’
When set to false or no (strongly recommended), security-sensitive information, such as the password, is not returned as part of the connection if the connection is open or has ever been in an open state.
Resetting the connection string resets all connection string values including the password.
Recognized values are true, false, yes, and no.

QUESTION 55
You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to create an application. The application retreives data from Microsoft SQL Server 2008 database named AdventureWorks. The AdventureWorks.dbo.ProductDetails table contains a column names ProductImages that uses a varbinary(max) data type. You write the following code segment. (Line numbers are included for reference only.)
01 SqlDataReader reader = command.ExecureReader(– empty phrase here –);
02 while(reader.Read())
03 {
04 pubID = reader.GetString(0);
05 stream = new FileStream(…);
06 writer = new BinaryWriter(stream);
07 startIndex = 0;
08 retval = reader.GetBytes(1, startIndex, outByte, 0, bufferSize);
09 while(retval == bufferSize)
10 {
11 …
12 }
13 writer.Write(outbyte, 0, (int)retval-1);
14 writer.Flush();
15 writer.Close();
16 stream.Close();
17 }
You need to ensure that the code supports streaming data from the ProductImages column. Which code segment should you insert at the empty phrase in line 01?

A.    CommandBehavior.Default
B.    CommandBehavior.KeyInfo
C.    CommandBehavior.SingleResult
D.    CommandBehavior.SequentialAccess

Answer: D
Explanation:
Default
The query may return multiple result sets. Execution of the query may affect the database state.
Default sets no CommandBehavior flags, so calling ExecuteReader(CommandBehavior.Default) is functionally equivalent to calling ExecuteReader().
KeyInfo The query returns column and primary key information. When KeyInfo is used for command execution, the provider will append extra columns to the result set for existing primary key and timestamp columns.
SingleResult The query returns a single result set.
SequentialAccess Provides a way for the DataReader to handle rows that contain columns with large binary values.
Rather than loading the entire row, SequentialAccess enables the DataReader to load data as a stream.
You can then use the GetBytes or GetChars method to specify a byte location to start the read operation, and a limited buffer size for the data being returned.

QUESTION 56
You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to develop an application that connects to a Microsoft SQL Server 2008 database. The application performs a database query within a transaction. You need to ensure that the application can read data that has not yet beed commited by other transactions. Which IsolationLevel should you use?

A.    ReadUncommitted
B.    ReadCommitted
C.    RepeatableRead
D.    Unspecified

Answer: A
Explanation:
Unspecified A different isolation level than the one specified is being used, but the level cannot be determined.
When using OdbcTransaction, if you do not set IsolationLevel or you set IsolationLevel to Unspecified, the transaction executes according to the isolation level that is determined by the driver that is being used.
Chaos The pending changes from more highly isolated transactions cannot be overwritten. ReadUncommitted A dirty read is possible, meaning that no shared locks are issued and no exclusive locks are honored.
ReadCommitted Shared locks are held while the data is being read to avoid dirty reads, but the data can be changed before the end of the transaction, resulting in non-repeatable reads or phantom data.
RepeatableRead Locks are placed on all data that is used in a query, preventing other users from updating the data.
Prevents non-repeatable reads but phantom rows are still possible.
Serializable A range lock is placed on the DataSet, preventing other users from updating or inserting rows into the dataset until the transaction is complete.
Snapshot Reduces blocking by storing a version of data that one application can read while another is modifying the same data.
Indicates that from one transaction you cannot see changes made in other transactions, even if you requery.

B.    Change the Transform Related Text Templates On Save option to False.
C.    Add an ADO.NET Self-Tracking Entity Generator to the model.
D.    Add an ADO.NET EntityObject Generator to the model.

Answer: C
Explanation:
The ADO.NET Self-Tracking Entity Generator text template generates the object-layer code that consists of a custom typed ObjectContext and entity classes that contain self-tracking state logic so that the entities themselves keep track of their state instead of ObjectContext doing so. Probably the best usage of self-tracking entities is when working with N-tier applications.

QUESTION 80
You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to develop an application. You use the ADO.NET Entity Framework Designer to model entities. You retrieve an entity from an object context. A different application updates the database. You need to update the entity instance to reflect updated values in the database. Which line of code should you use?

A.    context.Refresh(RefreshMode.StoreWins, entity);
B.    context.LoadProperty(entity, “Client”, MergeOption.OverwriteChanges);
C.    context.AcceptAllChanges();
D.    context.LoadProperty(entity, “Server”, MergeOption.OverwriteChanges);

Answer: A
Explanation:
LoadProperty(Object, String) Explicitly loads an object related to the supplied object by the specified navigation property and using the default merge option. AcceptAllChanges Accepts all changes made to objects in the object context. Refresh(RefreshMode, Object) Updates an object in the object context with data from the data source.
ObjectContext.Refresh Method (RefreshMode, Object)
