Rational Performance Tester V8

Question No: 11

What is a key consideration for using a loop in a test?

  1. be sure to preserve the test flow and logic

  2. selectstatements to be enclosed in the loop

  3. set parameters for pacing the loop

  4. calculate the correct number of loop iterations for the expected duration of the test

Answer: A

Question No: 12

When should performance measurement of a test be recorded?

  1. when the system is reaching its steady state

  2. as soon as all virtual users hit the application

  3. after all virtual users reach synchronization point

  4. anytime after test execution

Answer: A

Question No: 13

What are three typical goals of performance testing? (Choose three.)

  1. identification of system response times

  2. capacity planning

  3. monitoring the network traffic

  4. scalability testing

  5. Think time determination

Answer: A,B,D

Question No: 14

What does checking quot;Show Referencesquot; in theTest Data view do?

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

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

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

  4. display automatically correlated data values in tabular form

Answer: D

Question No: 15

What is the main difference between correlated and pooled data?

  1. Correlated data all comes from the same row of the table, while pooled data uses a different line for eachrequest.

  2. A separate copy of correlated data is owned by each test agent, while pooled data is shared across all agents.

  3. Correlated data is varied at runtime, while pooled data is varied at record time.

  4. Correlated data is varied by the server, while pooled data is varied by the client.

Answer: D

Question No: 16

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

  1. datapooling

  2. creating a schedule

  3. resource monitoring

  4. profiling and logging

Answer: B Explanation:

What happens to an unused reference?

  1. It will not be used by any later request in the test.

  2. It will be automatically reset at the end of each test run.

  3. It will be automatically reset when the test is saved.

  4. It will become used if it matches a string in a later request. Answer: A

Question No: 17

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

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

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

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

  4. to simulate actual browser behavior

Answer: A

Question No: 18

Which three verification points can be applied at the element level? (Choose three.)

  1. Page Title VP

  2. Page Content VP

  3. Response Size VP

  4. Response Code VP

Answer: B,C,D

Question No: 19

What is the purpose for correcting time offset?

  1. to synchronize the workbench machine with all the virtual tester agents?machines

  2. to adjustfor daylight saving hours on the workbench machine

  3. to ensure that the response time breakdown test reports are correct

  4. to ensure that agent machines with faster CPU run at the same rate as slower machines

  5. to ensure all the data for response timebreakdown is time-stamped using the time from the workbench machine

Answer: C

Question No: 20

What is the easiest way that a current timestamp in a page request can be generated?

  1. by writing a custom code method that invokes java.util.Date

  2. by writing a custom code method that invokes java.util.Timer

  3. by correlating the timestamp value to a built-in datasource

  4. by using the NOW() Excel function in a column of a datapool
