Demo Question 7.

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 testing and stabilization of Applications. One of the EliteCertify.com Windows Forms applications contains the following production environment specifications: 1. The application is deployed to production desktop computers. 2. A Web service that is used by the application is deployed to a production Web server. 3. The production desktop computers run Microsoft Windows XP Professional. Following is the test environment specification for performance testing that the development team created: 1. The application is deployed to production desktop computers. 2. The Web service is deployed to a staging Web server. 3. The staging Web server's hardware configuration is identical to the production Web server. 4. The Web servers have 1 gigabyte (GB. of memory. You need to make a decision as to whether the test environment specification is appropriate. What conclusion can you draw?

A. The test environment is appropriate.
B. The test environment is inappropriate. The Web service should be deployed to the production Web server.
C. The test environment is inappropriate. The staging Web server's hardware configuration should be changed.
D. The test environment is inappropriate. The application should be deployed to test desktop computers.


Display Answer

Answer: D

Explanation: When testing an application for performance, one should perform testing in an isolated environment that is similar to the production environment and not to the production desktop computers as suggested in the question. The test environment is thus inappropriate. You should also be making use of test desktop computers. Incorrect answers: A. This is incorrect since you should not make use of production desktop computers when doing performance testing. B. You should not be deploying the Web service to the production server; it should be deployed to a staging server so as to facilitate the isolation aspect of performance testing. C. There is no need to change the hardware configuration of the staging server because the test environment should mimic the production environment which also includes hardware configuration.
