You are developing a Microsoft ASP.NET Web application. The application is hosted on a server named
WEB01.
The application uses a state server named SESS01 to maintain session information.
You need to track the number of sessions that become inactive due to user inactivity.
What should you do?

• A. Monitor the state server sessions that are timed out in SESS01.
• B. Monitor the state server sessions that are abandoned in WEB01.
• C. Monitor the state server sessions that are timed out in WEB01.
• D. Monitor the state server sessions that are abandoned in SESS01.

You are developing a Microsoft ASP.NET Web application. The application uses methods of the Trace
class.
You add a TextWriterTraceListener class to the Listeners collection that writes trace messages to a log file.
You need to ensure that the following requirements are met:
The trace messages are written to the TextWriterTraceListener class.
The trace output is accessible only by using the Trace Viewer or by viewing the log file.
Which trace element should you add to the configuration file of the application?

• A. <trace enabled="true" pageOutput="true" writeToDiagnosticsTrace="false"/>
• B. <trace enabled="true" pageOutput="false" writeToDiagnosticsTrace="false"/>
• C. <trace enabled="true" pageOutput="true" writeToDiagnosticsTrace="true"/>
• D. <trace enabled="true" pageOutput="false" writeToDiagnosticsTrace="true"/>

You are debugging a Web application.
Users must be able to perform a search on the Search page of the application by performing the following tasks:
Selecting an item from a data-bound DropDownList control named ddlRoles
Clicking a Button control named btnSearch
The code-behind file for the Search page contains the following code segment. (Line numbers are included for reference only.)
01 protected void Page_Load(
02 object sender, EventArgs e) {
04 PopulateDropDownList();
06 }
07 protected void btnSearch_Click(
08 object sender, EventArgs e) {
09 PerformSearch(ddlRoles.SelectedItem.Value);
10 }
Each time the user clicks the Search button, the selected item in the DropDownList control is changed to the first item in the control and the search results for the first item are displayed.
You need to ensure that a user can perform a search by using the selected item as the search parameter.
Which code segment should you use to replace lines 03 through 05?

• A. if (!Page.IsPostBack) { PopulateDropDownList(); }
• B. if (!Page.IsAsync) { PopulateDropDownList(); }
• C. if (!Page.IsCallback) { PopulateDropDownList(); }
• D. if (!Page.IsCrossPagePostBack) { PopulateDropDownList(); }
