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.

What happens to all the page elements in a test?

A. They are grouped by page unless the application under test uses AJAX.

B. They are grouped by page as a visual aid to enhance readability.

C. They are assigned dynamically to separate virtual testers at playback time.

D. They use separate records from a single datapool.

What does checking "Show References" in the Test Data view do?

A. highlight the regular expression being used to capture each reference

B. jump forward from a response to the correlated request that refers to it

C. jump back from the correlated request to the response that refers to it

D. display automatically correlated data values in tabular form

Which option in IBM Rational Performance Tester helps in emulating workloads?

A. datapooling

B. creating a schedule

C. resource monitoring

D. profiling and logging

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

When recording a test, how should you pace the test?

A. record the test slowly, allowing all pages to load completely so that all elements are fully loaded before proceeding to another page

B. record the test using your normal pace

C. record the test quickly, as pages do not need to load completely for the recording

D. record the test with varying paces to simulate the behavior of various types of users

What is a good step to verify the behavior of a schedule?

A. validate activity using events listing

B. view the input and output of the test while it is running

C. verify external schedules?interaction with the schedule

D. use Rational Quality Manager to run a report to look at the schedule data

Workload analysis is a design-time activity that includes which four processes? (Choose four.)

A. identifying the performance bottlenecks of the application

B. identifying the workload to be simulated or emulated in the performance tests, in terms of number of actors or actor classes and actor profiles

C. identifying the actors and actor characteristics to be simulated or emulated in the performance tests

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

Which statement is true about paced loops?

A. They are used to pace the execution of steps in a test.

B. They are the basis for running loops within schedules.

C. They verify that information is being sent between the application under test and IBM Rational Performance Tester.

D. They execute n iterations of an element per time segment.

What is the term used for the Product that simulates virtual load on the application under test?

A. Synthetic users

B. Real users

C. Virtual users

D. Load balancers
