QUESTION 90
You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to develop an application. You use the Entity Framework Designer to create the following Entity Data Model. You write a method named ValidatePostalCode to validate the postal code for the application. You need to ensure that the ValidatePostalCode method is called before the PostalCode property set method is completed and before the underlying value has changed. Which code segment should you place in the entity’s partial class?

A.    partial void OnPostalCodeChanged(string value)
{
PostalCode = GetValidValue<string>
(value, “ValidatePostalCode”, false, true) ;
}
B.    public string ValidatedPostalCode
{
   set
   {
ValidatePostalCode(value);
      _PostalCode = value;
   }
   get
   {
      return _PostalCode;
   }
}
C.    partial void OnPostalCodeChanging(string value)
{
   ValidatePostalCode(value);
}
D.    public string ValidatedPostalCode
{
   set
   {
      _PostalCode = StructuralObject.SetValidValue
(“ValidatePostalCode”, false);
   }
   get
   {
      return _PostalCode;
   }
}

Answer: C
Explanation:
Another area of extensibility is with the partial methods created on each entity type. There is a pair of partial methods called OnXxxChanging and OnXxxChanged for each property, in which Xxx is the name of the property. The OnXxxChanging method executes before the property has changed, and the OnXxxChanged method executes after the property has changed. To implement any of the partial methods, create a partial class and add the appropriate partial method with implementation code.

Cosiderations from Attaching and Detaching objects
http://msdn.microsoft.com/en-us/library/bb896271.aspx
The object that is passed to the Attach method must have a valid EntityKey value. If the object does not have a valid EntityKey value, use the AttachTo method to specify the name of the entity set.
Attach Use the Attach method of ObjectContext where the method accepts a single typed entity parameter.
AttachTo The AttachTo method of ObjectContext accepts two parameters. The first parameter is a string containing the name of the entity set.
The second parameter’ type is object and references the entity you want to add.
Attach The Attach method of ObjectSet, which is the entity set’ type, accepts a single typed parameter containing the entity to be added to the ObjectSet.

D.    var dt = new taStore.ProductDataTable();
var row = dt.NewProductRow();
row.ProductID = 680;
row.Name = “New Product Name”;
dt.Rows.Add(row) ;

Answer: A
Explanation:
DataRowCollection.Find() Method To use the Find method, the DataTable object to which the DataRowCollection object belongs to must have at least one column designated as a primary key column. See the PrimaryKey property for details on creating a PrimaryKey column, or an array of DataColumn objects when the table has more than one primary key.
var dt = new CustomersDS.CustomersDataTable();
var ta = new CustomersDSTableAdapters.CustomersTableAdapter();
ta.Fill(dt);
CustomersDS.CustomersRow row = (CustomersDS.CustomersRow)dt.Rows.Find(4); row.Name = “A. Found Customer Id”;
ta.Update(row);
DataTable.Select() Method Gets an array of all DataRow objects that match the filter criteria. To
create the filterExpression argument,
use the same rules that apply to the DataColumn class’s Expression
property value for creating filters.
var ta = new CustomersDSTableAdapters.CustomersTableAdapter();
var dt = ta.GetData();
var row = dt.Select(“CustomerID > 2”);
row[0][“Name”] = “B. Found Customer Id”;
ta.Update(row);

D.    Configuration config = WebConfigurationManager.OpenMachineConfiguration (“~”);
ConnectionStringsSection section = (ConnectionStringsSection)config.GetSection(“connectionStrings”);
section.Sectionlnformation.ProtectSection
(“DpapiProtectedConfigurationProvider”); config.Save ();

Answer: A
Explanation:
You encrypt and decrypt the contents of a Web.config file by using System.Configuration . DPAPIProtectedConfigurationProvider from the System.Configuration.dll assembly, which uses the Windows Data Protection API (DPAPI) to encrypt and decrypt data, or by using System.Configuration. RSAProtectedConfigurationProvider, which uses the RSA encryption algorithm to encrypt and decrypt data. When you use the same encrypted configuration file on many computers in a web farm, only System. Configuration.RSAProtectedConfigurationProvider enables you to export the encryption keys that encrypt the data and import them on another server. This is the default setting.

You need to ensure that the application meets the following requirements:
– Compares the current values of unmodified properties with values returned from the data source.
– Marks the property as modified when the properties are not the same.
Which code segment should you insert at line 02?

B.    context.MergeOption = MergeOption.PreserveChanges;
C.    context.MergeOption = MergeOption.OverwriteChanges;
D.    context.MergeOption = MergeOption.NoTracking;

Answer: B
Explanation:
PreserveChanges-Objects that do not exist in the object context are attached to the context. If the state of the entity is Unchanged, the current and original values in the entry are overwritten with data source values. The state of the entity remains Unchanged and no properties are marked as modified. If the state of the entity is Modified, the current values of modified properties are not overwritten with data source values. The original values of unmodified properties are overwritten with the values from the data source. In the .NET Framework version 4, the Entity Framework compares the current values of unmodified properties with the values that were returned from the data source. If the values are not the same, the property is marked as modified.

NEW QUESTION 168
Simulation
Scenario:
A Citrix Administrator must modify the store configuration on a StoreFront server to provide users with access to desktop OS machines and server OS hosted applications. A Delivery Controller named Controller-1 needs to be added to the existing site. Controller- 1 will serve as the Secure Ticket Authority. The administrator has been instructed to ensure communication with the Delivery Controllers takes place over port 8080.
Tasks:
1. Modify the store named Apps and Desktops to provide users with access to desktop OS machines and server OS hosted applications using hostnames only. Do NOT assume the FQDN.
2. Ensure communication with the Delivery Controllers take place over port 8080.
3. Set up Controller-1 as the Secure Ticket Authority.

Answer:
Citrix StoreFront Configuration

1. When the wizard starts enter a store name.

2. Now we need to add the delivery controllers (Controller1) that StoreFront will interface with


……

6. Once the store is created it will give you the web browser URL that you can use to access it. Also take note that to access StoreFront from a web browser you must append “Web” to the store URL, as the URL shows below. Don’t try going to /Citrix/Store as that won’t work.

7. To change the StoreFront base URL you can go to the Server Group node and in the right pane select Change Base URL. Change URL to use HTTPS and port 8080

8. Back in the StoreFront console, after refreshing, you can see that the service is using HTTPS.

9. One quick tweak to make authentication easier is to set a default domain. This way the user doesn’t have to enter a domain when authenticating to the StoreFront web site. Locate the Authentication node, then in the right pane click on Configure Trusted Domains.

And that’s pretty much it to get an operational StoreFront. If you open your browser and go to the full web store URL you should get a green bubbly Citrix receiver page.

Creating a XenDesktop 7 Delivery Group
1. When a new Delivery Group is created it will list all of your machine catalogs. It lists the number of computers in that catalog and one can choose how many to assign to my delivery group. You need not put all of the computers into a single delivery group.

2. Next up choose what combination of desktops and applications you want to deliver. But here you could assign the same desktop VM to everyone, but have different delivery groups that customize the mix of XenApp applications they get delivered.

3. Now you have to define what users or groups are part of the delivery group.

4. An optional step at this point is to define the StoreFront server(s) which the Receiver inside of the desktop will be configured to use. A great feature if you are using XenApp, or perhaps have another XenDesktop farm for R&D that some users should have access to.


5. The final step is configuring a Delivery Group name, and a display name. The display name is something users will see, so keep it simple.

6. And that’s it! A few seconds later you will have a nice delivery group in your console. In the right hand column make sure your VMs show a Registered state. If not, then you may have some networking (DHCP, DNS) or other issues preventing the VDA from properly communicating with the desktop controller.

7. Once the delivery group is created, you can Edit it and find more options that weren’t presented during the simplified wizard. For example, you can allow a user to access more than one desktop from the pool, change the color depth, time zone, and secure the ICA protocol with some lightweight encryption.

NEW QUESTION 140
Scenario:
Provisioning Services has been installed to facilitate the deployment of server OS and desktop OS machines. Currently, a pool of Windows 8 desktop OS machines is being used by the Imaging and Radiology team. A virtual machine OU named CCH Virtual Desktops has been created. However, users on the Imaging and Radiology team need to use their medical imaging applications that CANNOT be installed on their workstations due to insufficient resources. As the Citrix Engineer, you have been asked to provision desktop OS machines with sufficient resources to three Imaging and Radiology team members in order to allow them to use their new applications. All three of the desktop OS machines should be assigned the Win8 vDisk, and the desktop OS machines should maintain changes after reboot. Members of the Imaging and Radiology team need to be able to log into the CCH.com domain. The Windows 8 virtual machines were already created with the following information:

CCHWin801 – IR Desktop 1
•    IP Address: DHCP Assigned
•    MAC Address: 56:5b:b0:38:6a:54
•    NOT a member of Active Directory
•    CCHWin803 – IR Desktop 3
CCHWin802 – IR Desktop 2
•    IP Address: DHCP Assigned
•    MAC Address: be:c8:96:6e:89:c9
•    NOT a member of Active Directory
In order to save time, a copy of an existing Window 8 base image vDisk was created and named Win8 and is stored in the PVS StoreOI store. As the Citrix Engineer, use the existing site, store, and device collection to implement the tasks below.

Tasks:
1. Create and configure all 3 of the Windows 8 desktop OS machines as target devices to boot using the Win8 vDisk.
2. Name the target devices CCHWin801, CCHWin802, and CCHWin803.
3. Modify the vDisk as necessary to meet the requirements outlined in the scenario.

Answer:
XenDesktop 7 Machine Catalog
1. Create the VM in an existing catalog
2. Choose the OS type

3. We will be using VMs and Citrix Machine Creation Services, so the defaults are fine

4. Use the default

5. Choose the master image WIN8.vdisk

6. A great feature of XenDesktop is the ability to customize the catalog hardware at provisioning time, so you can offer different tiers of VMs from the exact same master image. No need to build up templates with the same OS and software stack, just to customize the vCPUs and memory specs

7.

8. After you kick off the provisioning process you get a nice status. MCS first makes a copy of your master VM, then does its magic to create copies

QUESTION 126
You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to create an application. You use the ADO.NET Entity Data Model (EDM) to define a Customer entity. You need to add a new Customer to the data store without setting all the customer’s properties. What should you do?

A.    Call the Create method of the Customer object.
B.    Call the CreateObject method of the Customer object.
C.    Override the Create method for the Customer object.
D.    Override the SaveChanges method for the Customer object.

Answer: B
Explanation:
CreateObject<T> Creates and returns an instance of the requested type.

QUESTION 127
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 use the ADO.NET Entity Framework to model your entities. You use ADO.NET self-tracking entities. You need to ensure that the change-tracking information for the self-tracking entities can be used to update the database. Which ObjectContext method should you call after changes are made to the entities?

A.    Attach
B.    Refresh
C.    SaveChanges
D.    ApplyChanges

Answer: D
Explanation:
ApplyChanges takes the changes in a connected set of entities and applies them to an ObjectContext.
Starting with Microsoft Visual Studio 2010, the ADO.NET Self-Tracking Entity Generator template generates self-tracking entities.
This template item generates two .tt (text template) files: <model name>.tt and <model name>.Context.tt.
The <model name>.tt file generates the entity types and a helper class that contains the change-tracking logic that is used by self-tracking entities and the extension methods that allow setting state on self-tracking entities.
The <model name>.Context.tt file generates a typed ObjectContext and an extension class that contains ApplyChanges methods for the ObjectContext and ObjectSet classes. These methods examine the change-tracking information that is contained in the graph of self- tracking entities to infer the set of operations that must be performed to save the changes in the database.

QUESTION 128
You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to create an application. The application uses the ADO.NET Entity Framework to manage Plain Old CLR Objects (POCO) entities. You create a new POCO class. You need to ensure that the class meets the following requirements:
– It can be used by an ObjectContext.
– It is enabled for change-tracking proxies.
Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

A.    Modify each mapped property to contain sealed and protected accessors.
B.    Modify each mapped property to contain non-sealed, public, and virtual accessors.
C.    Configure the navigation property to return a type that implements the ICollection interface.
D.    Configure the navigation property to return a type that implements the IQueryable interface.
E.    Configure the navigation property to return a type that implements the IEntityWithRelationships interface.

QUESTION 129
You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to create an application. The application uses the ADO.NET Entity Framework to model entities. The application allows users to make changes while disconnected from the data store. Changes are submitted to the data store by using the SubmitChanges method of the DataContext object. You receive an exception when you call the SubmitChanges method to submit entities that a user has changed in offline mode. You need to ensure that entities changed in offline mode can be successfully updated in the data store. What should you do?

A.    Set the ObjectTrackingEnabled property of DataContext to true.
B.    Set the DeferredLoadingEnabled property of DataContext to true.
C.    Call the SaveChanges method of DataContext with a value of false.
D.    Call the SubmitChanges method of DataContext with a value of System.Data.Linq.ConflictMode.ContinueOnConflict.

Answer: A
Explanation:
ObjectTrackingEnabled Instructs the framework to track the original value and object identity for this DataContext.

QUESTION 130
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. The application uses the ADO.NET LINQ to SQL model to retrieve data from the database. The application will not modify retrieved data. You need to ensure that all the requested data is retrieved. You want to achieve this goal using the minimum amount of resources. What should you do?

A.    Set ObjectTrackingEnabled to true on the DataContext class.
B.    Set ObjectTrackingEnabled to false on the DataContext class.
C.    Set DeferredLoadingEnabled to true on the DataContext class.
D.    Set DeferredLoadingEnabled to false on the DataContext class.

Answer: B
Explanation:
Setting property ObjectTrackingEnabled to false improves performance at retrieval time, because there are fewer items to track.

QUESTION 131
You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to create an application. You use the ADO.NET Entity Framework to model your entities. You use Plain Old CLR Objects (POCO) entities along with snapshot-based change tracking. The code accesses the POCO entities directly. You need to ensure that the state manager synchronizes when changes are made to the object graph. Which ObjectContext method should you call?

A.    Refresh
B.    SaveChanges
C.    DetectChanges
D.    ApplyPropertyChanges

Answer: C
Explanation:
When working with POCO, you must call the DetectChanges method on the ObjectContext to attach the POCO entity to the ObjectContext. Be sure to call DetectChanges prior to calling SaveChanges. ApplyPropertyChanges Obsolete. Applies property changes from a detached object to an object already attached to the object context.
CHAPTER 6 ADO.NET Entity Framework
Lesson 2: Querying and Updating with the Entity Framework Attaching Entities to an ObjectContext (page 438)

QUESTION 132
You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to create an application. The application uses the ADO.NET Entity Framework to model entities. The application includes a Customer entity along with a CustomerKey property of the Guid type as shown in the following exhibit. You discover that when the application adds a new instance of a Customer, calling the SaveChanges method results in the following error message:
“Server generated keys are only supported for identity columns.”
You need to ensure that the application can add new Customer entities. What should you do?

A.    Add a handler for the ObjectContext.SavingChanges event. In the event handler, set the CustomerKey value.
B.    Add a handler for the ObjectContext.ObjectMaterialized event. In the event handler, set the CustomerKey value.
C.    Call the ObjectContext.Attach method before saving a Customer entity.
D.    Call the ObjectContext.CreateEntityKey method before saving a Customer entity.

Answer: A
Explanation:
SavingChanges() Event Occurs when changes are saved to the data source. ObjectMaterialized() Event Occurs when a new entity object is created from data in the data source as part of a query or load operation. Attach() Method Attaches an object or object graph to the object context when the object has an entity key. CreateEntityKey() Creates the entity key for a specific object, or returns the entity key if it already exists.

QUESTION 133
You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to create an application. You use the ADO.NET Entity Framework to model entities. The application connects to a Microsoft SQL Server database named AdventureWorks. The application includes the following code segment. (Line numbers are included for reference only.)
01 using (AdventureWorksEntities context = new AdventureWorksEntities())
02 {
03 ObjectQuery <SalesOrderHeader> orders = context.SalesOrderHeader.
    Where(“it.CreditCardApprovalCode IS NULL”).Top(“100”);
04 foreach (SalesOrderHeader order in orders){
05 order.Status = 4;
06 }
07     try {
08         context.SaveChanges();
09     }
10     catch (OptimisticConcurrencyException){
11         …
12     }
13 }
You need to resolve any concurrency conflict that can occur. You also need to ensure that local changes are persisted to the database. Which code segment should you insert at line 11?

A.    context.Refresh(RefreshMode.ClientWins, orders);
context.AcceptAllChanges();
B.    context.Refresh(RefreshMode.ClientWins, orders);
context.SaveChanges();
C.    context.Refresh(RefreshMode.StoreWins, orders);
context.AcceptAllChanges();
D.    context.Refresh(RefreshMode.StoreWins, orders);
context.SaveChanges();

Answer: B
Explanation:
SaveChanges() Persists all updates to the data source and resets change tracking in the object context.
Refresh(RefreshMode, Object) Updates an object in the object context with data from the data source.
AcceptAllChanges() Accepts all changes made to objects in the object context. Refresh(RefreshMode refreshMode, Object entity) Method has the dual purpose of allowing an object to be refreshed with data from the data source and being the mechanism by which conflicts can be resolved.

QUESTION 134
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. The application uses the following object query to load a product from the database. (Line numbers are included for reference only.)
01 using (AdventureWorksEntities advWorksContext = new AdventureWorksEntities())
02 {
03    ObjectQuery <Product> productQuery = advWorksContext.Product.Where(“it.ProductID = 900”);
04    …
05 }
You need to log the command that the query executes against the data source. Which code segment should you insert at line 04?

A.    Trace.WriteLine(productQuery.ToString());
B.    Trace.WriteLine(productQuery.ToTraceString());
C.    Trace.WriteLine(productQuery.CommandText);
D.    Trace.WriteLine(((IQueryable)productQuery).Expression);

QUESTION 135
You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to create a Windows Forms application. The application connects to a Microsoft SQL Server database. You need to find out whether the application is explicitly closing or disposing SQL connections. Which code segment should you use?

A.    string instanceName = Assembly.GetEntryAssembly().FullName;
PerformanceCounter perf = new PerformanceCounter(“.NET Data Provider for SqlServer”, “NumberOfReclaimedConnections”, instanceName, true);
int leakedConnections = (int)perf.NextValue();
B.    string instanceName = Assembly.GetEntryAssembly().GetName().Name;
PerformanceCounter perf = new PerformanceCounter(“.NET Data Provider for SqlServer”, “NumberOfReclaimedConnections”, instanceName, true);
int leakedConnections = (int)perf.NextValue();
C.    string instanceName = Assembly.GetEntryAssembly().FullName;
PerformanceCounter perf = new PerformanceCounter(“.NET Data Provider for SqlServer”, “NumberOfNonPooledConnections”, instanceName, true);
int leakedConnections = (int)perf.NextValue();
D.    string instanceName = Assembly.GetEntryAssembly().GetName().Name;
PerformanceCounter perf = new PerformanceCounter(“.NET Data Provider for SqlServer”, “NumberOfNonPooledConnections”, instanceName, true);
int leakedConnections = (int)perf.NextValue();

Answer: A
Explanation:
NumberOfNonPooledConnections The number of active connections that are not pooled. NumberOfReclaimedConnections The number of connections that have been reclaimed through garbage collection where Close or Dispose was not called by the application. Not explicitly closing or disposing connections hurts performance.

QUESTION 136
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 write the following code segment that executes two commands against the database within a transaction. (Line numbers are included for reference only.)
01 using(SqlConnection connection = new SqlConnection(cnnStr)) {
02      connnection.Open();
03      SqlTransaction sqlTran = connection.BeginTransaction();
04      SqlCommand command = connection.CreateCommand();
05      command.Transaction = sqlTran;
06      try{
07         command.CommandText = “INSERT INTO Production.ScrapReason(Name) VALUES(‘Wrong size’)”;
08         command.ExecuteNonQuery();
09         command.CommandText = “INSERT INTO Production.ScrapReason(Name) VALUES(’Wrong color’)”;
10         command.ExecuteNonQuery();
11         …
12   }
You need to log error information if the transaction fails to commit or roll back. Which code segment should you insert at line 11?

A.           sqlTran.Commit();
}
catch (Exception ex) {
       sqlTran.Rollback();
       Trace.WriteLine(ex.Message);
}
B.           sqlTran.Commit();
}
catch (Exception ex) {
       Trace.WriteLine(ex.Message);
       try {
              sqlTran.Rollback();
       }
       catch (Exception exRollback) {
              Trace.WriteLine(exRollback.Message);
       }
}
C.    catch (Exception ex){
       Trace.WriteLine(ex.Message);
       try{
              sqlTran.Rollback();
       }
       catch (Exception exRollback){
              Trace.WriteLine(exRollback.Message);
       }
}
finaly {
       sqltran.commit( );
}
D.    catch (Exception ex) {
       sqlTran.Rollback();
       Trace.WriteLine(ex.Message);
}
finaly {
       try {
              sqltran.commit( );
       }
       catch (Exception exRollback) {
Trace.WriteLine(excommit.Message);
       }
}

Answer: B
Explanation:
A would work, but B is better since we are checking for possible errors during the rollback. C & D would try to do a rollback before a commit? The finally block is only executed when the application ends, which may not be the appropriate place to put this logic. Normally, a finally block would contain code to close a Database connection. The finally block executes even if an exception arises.

QUESTION 142
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. The application uses the ADO.NET Entity Framework to manage order data. The application makes a Web service call to obtain orders from an order-tracking system. You need to ensure that the orders are added to the local data store. Which method should you call on the ObjectContext?

A.    Attach
B.    AttachTo
C.    AddObject
D.    ApplyCurrentValues

Answer: C
Explanation:
ObjectContext.AddObject() Call AddObject on the ObjectContext to add the object to the object context.
Do this when the object is a new object that does not yet exist in the data source. ObjectContext.Attach() Call Attach on the ObjectContext to attach the object to the object context.
Do this when the object already exists in the data source but is currently not attached to the context.
If the object being attached has related objects, those objects will also be attached to the object context.
Objects are added to the object context in an unchanged state.
The object that is passed to the Attach method must have a valid EntityKey value. If the object does not have a valid EntityKey value, use the AttachTo method to specify the name of the entity set.
ObjectContext.AttachTo() Call AttachTo on the ObjectContext to attach the object to a specific entity set in the object context or if the object has a null (Nothing in Visual Basic) EntityKey value.
The object being attached is not required to have an EntityKey associated with it. If the object does not have an entity key, then entitySetName cannot be an empty string. 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.

QUESTION 143
You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to develop an application. You use the Entity Framework Designer to create an Entity Data Model using model-first development. The database has the following requirements:

– each table requires a trigger that updates the value of the time_modified column when a row is inserted or updated
You need to ensure that the database script that is created by using the Generate Database From Model option meets the requirements. What should you do?

A.    Create a new T4 template, and set the DDL Generation template to the name of the new template.
B.    Create a new Windows Workflow Foundation workflow, and set Database Generation Workflow to the name of the new workflow.
C.    Add a DateTime property named time_modified to each entity in the model and set the property’s StoreGeneratedPattern to Computed.
D.    Add a new entity named time_modified to the model, and modify each existing entity so that it inherits from the new entity.

You are developing a new feature that displays an auto-complete list to users as the type color names. You have an existing ContosoEntities context object named contex. To support the new feature you must develop code that will accept a string object named text containing a user’s partial input and will query the Colors database table to retrieve all color names that begin with that input. You need to create an Entity SQL (ESQL) query to meet the requirement. The query must not be vulnerable to a SQL injection attack. Which code segment should you use?

A.    var parameter = new ObjectParameter(“text”, text + “%”);
var result = context.CreateQuery<string>(“SELECT VALUE (c.Name) FROM Colors AS c WHERE c.Name LIKE ‘@text'”, parameter);
B.    var parameter = new ObjectParameter(“text”, text + “%”);
var result = context.CreateQuery<string>(“SELECT VALUE (c.Name) FROM Colors AS c WHERE c.Name LIKE @text”, parameter);
C.    var parameter = new ObjectParameter(“text”, text + “%”);
var result = context.CreateQuery<string>(“SELECT (c.Name) FROM Colors AS c WHERE c.Name LIKE @text”, parameter);
D.    var parameter = new ObjectParameter(“text”, HttpUtility.HtmlEncode(text) + “%”);
var result = context.CreateQuery<string>(“SELECT (c.Name) FROM Colors AS c WHERE c.Name LIKE ‘@text’@, parameter);

Answer: B
Explanation:
Entity SQL supports two variants of the SELECT clause. The first variant, row select, is identified by the SELECT keyword, and can be used to specify one or more values that should be projected out. Because a row wrapper is implicitly added around the values returned, the result of the query expression is always a multiset of rows. Each query expression in a row select must specify an alias. If no alias is specified,Entity SQL attempts to generate an alias by using the alias generation rules. The other variant of the SELECT clause, value select, is identified by the SELECT VALUE keyword. It allows only one value to be specified, and does not add a row wrapper. A row select is always expressible in terms of VALUE SELECT, as illustrated in the following example.

NEW QUESTION 213
You need to configure Server1 to meet the cloud infrastructure requirements. What should you do?

A.    Reinstall VMM.
B.    Create a mirrored volume.
C.    Install the Storage Replica feature.
D.    Create a storage space and use the mirror resiliency type.

Answer: C
Explanation:
Storage Replica (SR) is a new feature that enables storage-agnostic, block-level, synchronous replication between servers for disaster recovery, as well as stretching of a failover cluster for high availability. Synchronous replication enables mirroring of data in physical sites with crash-consistent volumes ensuring zero data loss at the file system level. Asynchronous replication allows site extension beyond metropolitan ranges with the possibility of data loss.
Scenario:
* Server1 is in a private cloud in the Seattle Office
* Infrastructrure requirements include:
Ensure that all of the private cloud components are highly available.

QUESTION 166
You use Microsoft .NET Framework 4.0 to develop an application that uses LINQ to SQL. The Product entity in the LINQ to SQL model contains a field named Productlmage. The Productlmage field holds a large amount of binary data. You need to ensure that the Productlmage field is retrieved from the database only when it is needed by the application. What should you do?

A.    Set the Update Check property on the Productlmage property of the Product entity to Never.
B.    Set the Auto-Sync property on the Productlmage property of the Product entity to Never.
C.    Set the Delay Loaded property on the Productlmage property of the Product entity to True.
D.    When the context is initialized, specify that the Productlmage property should not be retrieved by using DataLoadOptions

Answer: C
Explanation:
Lazy loading is configured in the LINQ to SQL designer by selecting an entity and then, in the Properties window, setting the Delay Loaded property to true.The Delay Loaded property indicates that you want lazy loading of the column.

How to: Call Model-Defined Functions in Queries
http://msdn.microsoft.com/en-us/library/dd456857.aspx
The model-defined function has been created in the conceptual model, but you still need a way to connect your code to it. To do so, add a function into your C# code, which will have to be annotated with the EdmFunctionAttribute attribute. This function can be another instance method of the class itself, but best practice is to create a separate class and define this method as static.

QUESTION 175
You use Microsoft .NET Framework 4.0 to develop an application that connects to a Microsoft SQL Server 2008 database. The application uses nested transaction scopes. An inner transaction scope contains code that inserts records into the database. You need to ensure that the inner transaction can successfully commit even if the outer transaction rolls back. What are two possible TransactionScope constructors that you can use for the inner transaction to achieve this goal? (Each correct answer presents a complete solution. Choose two.)

A.    TransactionScope(TransactionScopeOption.Required)
B.    TransactionScope()
C.    TransactionScope(TransactionScopeOption.RequiresNew)
D.    TransactionScope(TransactionScopeOption.Suppress)

Answer: CD
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.

You need to retrieve a list of all Products from todays sales orders for a specified customer. You also need to ensure that the application uses the minimum amount of memory when retrieving the list. Which code segment should you insert at line 02?

A.    Contact customer = context.Contact.Where(“it.ContactID = @customerId”, new ObjectParameter(“customerId”, customerId)).First();
customer.SalesOrderHeader.Load();
foreach (SalesOrderHeader order in customer.SalesOrderHeader)
{
  order.SalesOrderDetail.Load();
  if (order.OrderDate.Date == DateTime.Today.Date)
  {
    foreach (SalesOrderDetail item in order.SalesOrderDetail)
    {
Console.WriteLine(String.Format(“Product: {0} “, item.ProductID));
    }
  }
}
B.    Contact customer = context.Contact.Where(“it.ContactID = @customerId”, new ObjectParameter(“customerId”, customerId)).First();
customer.SalesOrderHeader.Load();
foreach (SalesOrderHeader order in customer.SalesOrderHeader)
{
  if (order.OrderDate.Date == DateTime.Today.Date)
  {
    order.SalesOrderDetail.Load();
    foreach (SalesOrderDetail item in order.SalesOrderDetail)
    {
Console.WriteLine(String.Format(“Product: {0} “, item.ProductID));
    }
  }
}
C.    Contact customer = (from contact in context.Contact.Include(“SalesOrderHeader”) select contact).FirstOrDefault();
foreach (SalesOrderHeader order in customer.SalesOrderHeader)
{
  order.SalesOrderDetail.Load();
  if (order.OrderDate.Date == DateTime.Today.Date)
  {
    foreach (SalesOrderDetail item in order.SalesOrderDetail)
    {
Console.WriteLine(String.Format(“Product: {0} “, item.ProductID));
    }
  }
}
D.    Contact customer = (from contact in context.Contact.Include(“SalesOrderHeader.SalesOrderDetail”) select contact).FirstOrDefault();
foreach (SalesOrderHeader order in customer.SalesOrderHeader)
{
  if (order.OrderDate.Date == DateTime.Today.Date)
  {
    foreach (SalesOrderDetail item in order.SalesOrderDetail)
    {
Console.WriteLine(String.Format(“Product: {0} “, item.ProductID));
    }
  }
}

Answer: B
Explanation:
A & C check the Order date after Order Detail, so we are retrieving more Order details than necessary. D is calling a Function (using eager loading) for the First Contact record only, so does not meet the requirements.

QUESTION 185
You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to create an application. The application contains the following code segment. (Line numbers are included for reference only.)
01 class DataAccessLayer
02 {
03   private static string connString;
04   …
05   …
06   public static DataTable GetDataTable(string command){
07   …
08   …
09   }
10 }
You need to define the connection life cycle of the DataAccessLayer class. You also need to ensure that the application uses the minimum number of connections to the database. What should you do?

A.    Insert the following code segment at line 04.
private static SqlConnection conn = new SqlConnection(connString);
public static void Open()
{
   conn.Open();
}
public static void Close()
{
   conn.Close();
}
B.    Insert the following code segment at line 04.
private SqlConnection conn = new SqlConnection(connString);
public void Open()
{
   conn.Open();
}
public void Close()
{
   conn.Close();
}
C.    Replace line 01 with the following code segment.
class DataAccessLayer : IDisposable
Insert the following code segment to line 04.
private SqlConnection conn = new SqlConnection(connString);
public void Open()
{
   conn.Open();
}
public void Dispose()
{
   conn.Close();
}
D.    Insert the following code segment at line 07:
using (SqlConnection conn = new SqlConnection(connString))
{
   conn.Open();
}

Answer: D
Explanation:
One thing you should always do is to make sure your connections are always opened within a using statement. Using statements will ensure that even if your application raises an exception while the connection is open, it will always be closed (returned to the pool) before your request is complete. This is very important, otherwise there could be connection leaks.

QUESTION 186
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 contains two SqlCommand objects named cmd1 and cmd2. You need to measure the time required to execute each command. Which code segment should you use?

A.    Stopwatch w1 = new Stopwatch();
w1.Start();
cmd1.ExecuteNonQuery();
w1.Stop();
Trace.WriteLine(w1.ElapsedMilliseconds);
w1.Start();
cmd2.ExecuteNonQuery();
w1.Stop();
Trace.WriteLine(w1.ElapsedMilliseconds);
B.    Stopwatch w1 = new Stopwatch();
w1.Start();
cmd1.ExecuteNonQuery();
w1.Stop();
Trace.WriteLine(w1.ElapsedMilliseconds);
w1.Reset();
cmd2.ExecuteNonQuery();
w1.Stop();
Trace.WriteLine(w1.ElapsedMilliseconds);
C.    Stopwatch w1 = Stopwatch.StartNew();
cmd1.ExecuteNonQuery();
w1.Stop();
Trace.WriteLine(w1.ElapsedMilliseconds);
w1.Start();
cmd2.ExecuteNonQuery();
w1.Stop();
Trace.WriteLine(w1.ElapsedMilliseconds);
D.    Stopwatch w1 = Stopwatch.StartNew();
cmd1.ExecuteNonQuery();
w1.Stop();
Trace.WriteLine(w1.ElapsedMilliseconds);
w1 = Stopwatch.StartNew();
cmd2.ExecuteNonQuery();
w1.Stop();
Trace.WriteLine(w1.ElapsedMilliseconds);

Answer: D
Explanation:
A & C do not reset the stopwatch before running cmd2. B does not start the stopwatch after resetting the stopwatch Start() does not reset the stopwatch, whereas StartNew() will create a new instance of the Stop watch and initialise the elapsed time to Zero.

You use Microsoft .NET Framework 4.0 to develop an application that connects to a Microsoft SQL Server 2008 database. You add the following table to the database.
CREATE TABLE Orders(
ID numeric(18, 0) NOT NULL,
OrderName varchar(50) NULL,
OrderTime time(7) NULL,
OrderDate date NULL)
You write the following code to retrieve data from the OrderTime column. (Line numbers are included for reference only.)
01 SqlConnection conn = new SqlConnection(“…”);
02 conn.Open();
03 SqlCommand cmd = new SqlCommand(“SELECT ID, OrderTime FROM Orders”, conn);
04 SqlDataReader rdr = cmd.ExecuteReader();
05 ….
06 while(rdr.Read())
07 {
08     ….
09 }
You need to retrieve the OrderTime data from the database. Which code segment should you insert at line 08?

A.    TimeSpan time = (TimeSpan)rdr[1];
B.    Timer time = (Timer)rdr[1];
C.    string time = (string)rdr[1];
D.    DateTime time = (DateTime)rdr[1];

Answer: A
Explanation:

QUESTION 199
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. The model contains an entity type named Product. You need to ensure that a stored procedure will be invoked when the ObjectContext.SaveChanges method is executed after an attached Product has changed. What should you do in the ADO.NET Entity Framework Designer?

A.    Add a new entity that has a base class of Product that is mapped to the stored procedure.
B.    Add a stored procedure mapping for the Product entity type.
C.    Add a complex type named Product that is mapped to the stored procedure.
D.    Add a function import for the Product entity type.

Answer: B
Explanation:
The ObjectContext class exposes a SaveChanges method that triggers updates to the underlying database.
By default, these updates use SQL statements that are automatically generated, but the updates can use stored procedures that you specify.
The good news is that the application code you use to create, update, and delete entities is the same whether or not you use stored procedures to update the database.
To map stored procedures to entities, in the Entity Framework designer, right-click the entity and choose Stored Procedure Mapping.
In the Mapping Details window assign a stored procedure for insert, update, and delete.

Answer: A

QUESTION 202
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. The application has two DataTable objects that reference the Customers and Orders tables in the database. The application contains the following code segment. (Line numbers are included for reference only.)
01 DataSet customerOrders = new DataSet();
02 customerOrders.EnforceConstraints = true;
03 ForeignKeyConstraint ordersFK = new ForeignKeyConstraint(“ordersFK”,
04                                    customerOrders.Tables[“Customers”].Columns[“CustomerID”],
05                                    customerOrders.Tables[“Orders”].Columns[“CustomerID”]);
06 …
07 customerOrders.Tables[“Orders”].Constraints.Add(ordersFK);
You need to ensure that an exception is thrown when you attempt to delete Customer records that have related Order records. Which code segment should you insert at line 06?

A.    ordersFK.DeleteRule = Rule.SetDefault;
B.    ordersFK.DeleteRule = Rule.None;
C.    ordersFK.DeleteRule = Rule.SetNull;
D.    ordersFK.DeleteRule = Rule.Cascade;

Answer: B
Explanation:
None No action taken on related rows, but exceptions are generated.
Cascade Delete or update related rows. This is the default.
SetNull Set values in related rows to DBNull.
SetDefault Set values in related rows to the value contained in the DefaultValue property. SetDefault specifies that all child column values be set to the default value.

QUESTION 205
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 ADO.NET Entity Framework to manage persistence-ignorant entities. You create an ObjectContext instance named context. Then, you directly modify properties on several entities. You need to save the modified entity values to the database. Which code segment should you use?

A.    context.SaveChanges(SaveOptions.AcceptAllChangesAfterSave);
B.    context.SaveChanges(SaveOptions.DetectChangesBeforeSave);
C.    context.SaveChanges(SaveOptions.None);
D.    context.SaveChanges();

Answer: B
Explanation:
None Changes are saved without the DetectChanges or the AcceptAllChangesAfterSave() methods being called.
AcceptAllChangesAfterSave After changes are saved, the AcceptAllChangesAfterSave() method is called, which resets change tracking in the ObjectStateManager.
DetectChangesBeforeSave Before changes are saved, the DetectChanges method is called to synchronize the property values of objects that are attached to the object context with data in the ObjectStateManager.

QUESTION 206
You develop a Microsoft .NET application that uses Entity Framework to store entities in a Microsft SQL Server 2008 database. While the application is disconnected from the database, entities that are modified, are serialized to a local file. The next time the application connects to the database, it retrieves the identity from the database by using an object context named context and stores the entity in a variable named remoteCustomer. The application then serializes the Customer entity from the local file and stores the entity in a variable named localCustomer. The remoteCustomer and the localCustomer variables have the same entity key. You need to ensure that the offline changes to the Customer entity is persisted in the database when the ObjectContext.SaveChanges() method is called. Which line of code should you use?

A.    context.ApplyOriginalValues(“Customers”, remoteCustomer);
B.    context.ApplyOriginalValues(“Customers”, localCustomer);
C.    context.ApplyCurrentValues(“Customers”, remoteCustomer);
D.    context.ApplyCurrentValues(“Customers”, localCustomer);
