C9510-058 Online Practice Questions and Answers

After a test run, the tester sums up all the individual requests response times but discovers that the total is not equal to the overall page response time. What are three causes of the difference? (Choose three.)

A. There is a defect in IBM Rational Performance Tester 8.2 that will be fixed in the next fix pack.

B. The page response time is more than the sum of the requests because it accounts for time taken to set up the connections.

C. The page response time is less than the sum of the requests because several requests could have been executed concurrently.

D. The page response time is more than the sum of the requests because custom code for response correlation in a page is executed serially and is added to the page response time.

E. The page response time is less than the sum of the requests because the response for the request is in the system cache.

Two workstations are installed with the full IBM Rational Performance Tester 8.2 product in addition to a

server that is installed with the IBM Rational Agent Controller. Stress testing is conducted with all the machines. Response time breakdown data is collected. Later the tester discovers that the data was in fact not collected. What are four probable causes? (Choose four.)

A. The server has not been instrumented.

B. IBM Rational Performance Tester is running on the other workstation.

C. The response time breakdown collection has not been enabled.

D. The firewall between the server and the two servers has not been opened.

E. IBM Rational Performance Tester 8.2 is not compatible with IBM Rational Agent Controller.

F. IBM Rational Agent Controller is not running on the workstation.

Why should you clear the cache when you record a test?

A. to force the browser to download all page elements resulting in a more accurate test

B. to force the browser to download all page elements resulting in longer page load times

C. to simulate a new user who has never used the application

D. to simulate actual browser behavior

D. clarifying the objectives of performance testing and the use cases

E. determining the performance measures and criteria

F. identifying the quality of application architecture

How do you set the condition in an if-then statement?

A. use the value of a string or a reference to control executing specified HTTP requests

B. select a reference that has been previously defined in the test

C. enter a string that has been previously defined in the test

D. set a condition that can be evaluated to be true or false

How can you guarantee unique datapool values across a very large test?

A. have each user draw from a private view of the datapool

B. wrap when the last row of the datapool is reached

C. fetch a datapool record only once for each virtual user

D. segment the datapool so that each agent machine has its own datapool records

What is the term for accurately defining the loading conditions under which the target test items must operate within their target configuration environment?
