Correct Answer: Use Microsoft Windows authentication in the application. Use a single Windows account for users to access the SQL Server database from your application.
Explanation:
We should only use one account to access the SQL Server database. This ensures that connection pooling is optimized.
Incorrect Answers:
A: We should only use a single account to access the SQL Server database.
C: Form-based authentication is less secure. Furthermore, running as the System Administrator with the sa login would compromise security.
D: Form-based authentication is less secure. Furthermore, creating a separate SQL Server login for each user is a daunting administrative task.
Correct Answer: Create an installer that has a custom action to install only location-specific files.
Explanation:
Custom actions are a Windows Installer feature that allows you to run code at the end of an installation to perform actions that cannot be handled during installation. This is an appropriate solution for this scenario as we only want to deploy the resource files on the server.
Incorrect Answers:
A: We just want to deploy the resource files. We do not need to set the Context property in the application.
B: We don?t need any launch conditions. We just want to deploy the resource files.
D: We just want to deploy the resource files.
Correct Answer: For each image, set the ToolTip property to specify the text you want to display.
Explanation:
WebControl.ToolTip property gets or sets the text displayed when the mouse pointer hovers over the Web server control. The use of the ToolTip property meets the requirement of this scenario.
Incorrect Answers:
A: The AlternateText property is used to specify the text to display if the image is not available.
C: The RaiseBubbleEvent is not useful here. ASP.NET server controls such as the Repeater, DataList and DataGrid Web controls can contain child controls that raise events. Rather than each button raising an event individually, events from the nested controls are "bubbled"?that is, they are sent to the control's parent.
D: The ToStringMethod() would not by itself provide the functionality required.
Correct Answer: Add the following directive to the page: OutputCache VaryByParam=?
Explanation:
You can vary user control output to the cache by specifying the user control name and the parameter. We use the VaryByParam attribute of the OutputCache
Incorrect Answers:
A: The Packet Size property of the Connection string is the size in bytes of the network packets sed to communicate with an instance of data provider. It is not an optimal property to change to optimize data retrieval.
C: The company database does not seem to include a region column.
D: If we keep the connection pool small we would allow less simulation connections. However, this would not minimize the required to retrieve and display the data.
Correct Answer: In the Web.config file for the application, set the culture attribute of the globalization element to en-NZ.
Explanation:
The culture attribute of the globalization element specifies the default culture for processing incoming Web requests.
Incorrect Answers:
B: The uiculture attribute of the globalization specifies the default culture for processing locale dependent resource searches. It does not apply in this scenario.
C, D: The UTF8Encoding Class class encodes Unicode characters using UCS Transformation Format, 8-bit form (UTF-8). This encoding supports all Unicode character values and surrogates. However, it does not help in displaying data in New Zealand format.
Correct Answer: an X-HTTP-Method header as part of a POST request
Correct Answer: Call the Refresh method of ObjectContext by using the RefreshMode.ClientWins method.
Correct Answer: ordersFK.DeleteRule = Rule.None;
Correct Answer: Set the Value property of the EntityReference of the Order entity.
Correct Answer: AESCryptoServiceProvider
