70-548 Designing and Developing Windows-Based Applications by Using the Microsoft .NET Framework Practice Test

Demo Question 3.

You work as the Enterprise application developer at EliteCertify.com. The EliteCertify.com network consists of a single Active Directory domain named EliteCertify.com. All servers in the domain run Windows Server 2003 and all client computers run Microsoft Windows XP Professional. Your responsibilities at EliteCertify.com include the deployment and support of Applications. EliteCertify.com operates as a financial institution. You need to evaluate a Microsoft Windows Forms application for EliteCertify.com. This application allows EliteCertify.com employees to access accounts on behalf of their customers. The application accesses an Extensible Markup Language (XML) Web service to authenticate users and retrieve account data. At present there are approximately 20,000 users that make use of this application. You need to evaluate the application's performance while it is in production. What should you do? (Each correct answer presents part of the solution. Choose two.)

A. Establish the total number of users that log on to the application on a given day.
B. Establish the longest elapsed time that a single user is logged on to the application.
C. Establish the time of day at which the largest number of users are logged on to the application.
D. Establish the largest number of times that a single user logs on to the application on a given day.
E. Evaluate the performance of the application for the single user.
F. Evaluate the performance of the application at that time.


Display Answer

Answer: C, F

Explanation: You should establish the time of day at which the largest number of users are logged on to the application. Then you should evaluate the application's performance at that time. You will be able to establish the time by tracking the user logon times. Incorrect answers: A. You should not establish the total number of users that log on to the application on a given day; you need to know when users are logged on to the application at the same time. B. You should not establish the longest elapsed time that a single user is logged on to the application because multiple users will access the application, you need to establish the time at which the largest number of users are logged on to the application at the same time. D : You should not establish the largest number of times that a single user logs on to the application on a given day because multiple users will access the application. Instead you need to establish the time at which the largest number of users are logged on to the application. E. You should be evaluating the application's performance for the largest number of users simultaneously logged on; and not the performance of the application for a single user.
