70-305 Developing and Implementing Web Applications with Microsoft Visual Basic.NET Certification Exam

Demo Question 11.

You work as the Web developer at EliteCertify.com. You create a new ASP.NET application named EliteCertify App03. You must enable instrumentation on each requested page of EliteCertify App03. Tracing must be displayed for only the initial thirty requests made to EliteCertify App03, and the trace information must be displayed at the bottom of each requested Web page. Choose the three actions which you should perform to accomplish these tasks. Each correct answer presents only part of the complete solution.

A. Define the value of the @ Page directive's Trace attribute to True on each Web page that must show the trace information.
B. Configure the Web.config file in EliteCertify App03's root directory to ensure that the Trace element's requestLimit attribute is set to 30.
C. Configure the Web.config file in EliteCertify App03's root directory to ensure that the Trace element's pageOutput attribute is set to True.
D. Set the value of the @ Page directive's Trace attribute to 30 on each Web page that must show the trace information.
E. Configure the Web.config file in EliteCertify App03's root directory to ensure that the Trace element's enabled attribute is set to True.


Display Answer

Answer: B, C, E To enable tracing for the first thirty requests of all pages in your application and to display trace information at the bottom of each page, you should configure the Web.config file so that the Trace element's enable attribute is set to true, the requestLimit attribute is set to 30 and the pageOutput attribute is set to true. Tracing can be enabled on a page-by-page basis by using the @ Page directive, or it can be enabled for an entire application by configuring the Web.config file in the application's root directory. In this scenario, it is more efficient to enable tracing through a single setting in the Web.config file than to modify every page's @ Page directive. The Web.config file should include these lines: <system.web> <trace enabled="true" pageOutput="true" requestLimit="30" /> </system.web> The pageOutput attribute determines where the trace information is displayed. Setting the pageOutput attribute to false, or not specifying a pageOutput value, will send the trace information to a Trace.axd file; a true value will send the information to both the Trace.axd file and the bottom of the Web page. The requestLimit attribute determines the number of requests for which to record trace information.
