Q:

You plan to deploy your ASP.NET application over XYZ’s intranet. The application uses data retrieved from a Microsoft SQL Server database. You want to use SQL Server connection pooling to optimize performance. You also need to protect confidential data stored on the server while minimizing administrative costs.

You need to configure security for your application. What should you do?

A) Use Microsoft Windows authentication in the application. Enable impersonation for users to access the SQL Server database from your application.	B) Use Microsoft Windows authentication in the application. Use a single Windows account for users to access the SQL Server database from your application.
C) Use form-based authentication in the application. Use the system administrator (sa) SQL Server login for users to access the SQL Server database from your application.	D) Use form-based authentication in the application. Assign each user a separate SQL Server login to use to access the SQL Server database from your application.

Answer & Explanation Answer: B) 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.

Q:

You create English, French, and German versions of a test engine ASP.NET application you are developing for XYZ Inc. You have separate resource files for each language version.You need to deploy the appropriate resource file based on the language settings of the server. What should you do?

A) Create an installer and set the Installer.Context property for each version of your application.	B) Create an installer that has a launch condition to verify the locale settings.
C) Create an installer that has a custom action to install only location-specific files.	D) Create an installer that has an MsiConfigureProduct function to install the appropriate version.

Answer & Explanation Answer: C) 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.

Q:

You are creating an ASP.NET application for XYZ. The company data is stored in a Microsoft SQL Server 6.5 database. Your application generates accounting summary reports based on transaction tables that contain million of rows.

You want your application to return each summary report as quickly as possible. You need to configure your application to connect to the database and retrieve the data in a away that achieves this goal.

What should you do?

A) Use a SqlConnection object to connect to the database, and use a SqlCommand object to run a stored procedure that returns the data.	B) Use an OleDbConnection object to connect to the database, and use an OleDbCommand object to run a stored procedure that returns the data.
C) Configure SQL Server to support HTTP access, and create an XML template to run a stored procedure that returns the data in XML format.	D) Use COM interop to create an ADODB.Connection object, and use an ADODB.Command object to run a SQL statement that returns the data.

Answer & Explanation Answer: B) Use an OleDbConnection object to connect to the database, and use an OleDbCommand object to run a stored procedure that returns the data.

Explanation:

We need to use an OleDBConnection to connect to SQL Server Version 6.5 (or earlier).

Incorrect Answers:

A: We could use a SqlConnection object only if the SQL Server were SQL Server 7.0, 2000 or later.

C: HTTP functionality is not required in this scenario. It would introduce unnecessary overhead.

D: ADODB is a legacy standard and should not be used here

Q:

You create an ASP.NET page that uses images to identify areas where a user can click to initiate actions. The users of the application use Internet Explorer.

You want to provide a pop-up window when the user moves the mouse pointer over an image. You want the pop-up window to display text that identifies the action that will be taken if the user clicks the image.

What should you do?

A) For each image, set the AlternateText property to specify the text you want to display, and set the ToolTip property to True.	B) For each image, set the ToolTip property to specify the text you want to display.
C) In the onmouseover event handler for each image, add code that calls the RaiseBubbleEvent() method of the System.Web.UI.WebControls.Image class.	D) In the onmouseover event handler for each image, add code that calls the ToString() method of the System.Web.UI.WebControls.Image class.

Answer & Explanation Answer: B) 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.

Q:

You are creating an ASP.NET page for selling movie tickets. Users select a region, and then they select from a list of cities in that region. The site displays the names and locations of movie theaters in the city selected by the user.

Your company, XYZ Brothers, maintains a list of theaters in a database table that includes the city, name, and street address of each theater. You want to minimize the time required to retrieve and display the list of theater names after a user selects the region and city.

What should you do?

A) Modify the connection string to add the packet size property and set its values to 8192.	B) Add the following directive to the page: OutputCache VaryByParam=?
C) Add the following directive to the page: OutputCache VaryByControl=?region;city?	D) Modify the connection string to keep your database's connection pool as small as possible.

Answer & Explanation Answer: B) 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.

Q:

You are a member of a team of developers creating several ASP.NET applications for XYZ. You want to create a reusable toolbar that will be used in each of the applications. The toolbar will be displayed at the top of each page viewed by the user.

The contents of the toolbar will vary depending on options each user selects when creating a profile.

You want to be able to add the toolbar to the ASP.NET toolbox for each of the developers on your team.What should you do?

A) Create a new Web Control Library project. Create the toolbar within a Web custom control.	B) Add a new Web user control to your ASP.NET project. Create the toolbar within the Web user control.
C) Add a new Web Form to your ASP.NET project. Design the toolbar within the Web Form and save the Web Form with an .ascx extension.	D) Add a new component class to your ASP.NET project. Design the toolbar within the designer of the component class.

Answer & Explanation Answer: A) Create a new Web Control Library project. Create the toolbar within a Web custom control.

Explanation:

Web custom controls are compiled code, which makes them easier to use but more difficult to create. You can add a Web custom control to the Toolbox and display it in a visual designer with full Properties window support and all the other design-time features of ASP.NET server controls.

Incorrect Answers:

B: Web user controls are easy to make, but they can be less convenient to use in advanced scenarios such as this. Because Web user controls are compiled dynamically at run time they cannot be added to the Toolbox

C: A Web form would be inadequate.

D: The Component class Provides the base implementation for the IComponent interface and enables object-sharing between applications. It does not fit in this scenario.

Q:

You create an ASP.NET application to provide corporate news and information to XYZ’s employees. The application is used by employees in New Zealand.

Default.aspx has a Web Form label control named currentDateLabel. The Page.Load event handler for Default.aspx included the following line of code:
currentDateLabel.Text = DateTime.Now.ToString(“D”)

You need to ensure that the data is displayed correctly for employees in New Zealand. What should you do?

A) In the Web.config file for the application, set the culture attribute of the globalization element to en-NZ.	B) In the Web.config file for the application, set the uiCulture attribute of the globalization element to en-NZ.
C) In Visual Studio .NET, set the responseEncoding attribute in the page directive for Default.aspx to UTF-8.	D) In Visual Studio .NET, save the Default.aspx page for both versions of the application by selecting Advanced Save Options from the File menu and selecting UTF-8.

Answer & Explanation Answer: A) 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.
