ISQI CTFL-PT : ISTQB Certified Tester Foundation Level-Performance Testing

How does a performance test script determine the duration of a request?

• A. Forking a child of itself and then blocking when the request is made and resuming operations when the result is received
• B. Starting a counter when the result is received and stopping the counter when the request is made
• C. Starting a timer when the request is made and stopping the timer when a result for the request is received.
• D. Entering an interrupt service routine when the request is made and returning when the result is received.

Which of the following activities Is performed last within a performance test run?

• A. Restore original data to ensure the system is in the proper state for testing
• B. Deploy load generators in places where users are located.
• C. Verify the test run functioned property by reviewing logs, database content and monitoring data
• D. Configure hardware and software to meet the test goal and plan

Which Is a valid reason for why performance testing load would be applied to the SUT in a ramp-up pattern during a performance test?

• A. Frequent sudden significant increases of toad allows the SUT performance to stabilize after each |ump in load thus exhibiting consistent behavior that results in measurements that are more reliable
• B. Frequent sudden significant increases of load ensures the SUT remains in a transient performance condition as it responds to each new large increase in load thus exhibiting consistent behavior that results in measurements that are more reliable.
• C. Gradually increasing the load allows the SUT performance to stablize after each progressive increment of load thus exhibiting consistent behavior that results in measurements that are more reliable
• D. Gradually increasing the load ensures the SUT remains in a transient performance condition as it responds to the new increase in load thus exhibiting realistic behavior that improves the realism of the performance test

You have been asked to test the performance of a software and system update to a North American mobile trivia quiz game application.The quiz app is available on major app stores serving English-speaking users.The number of concurrent users planned for is 5 million Winning quiz participants are promiseda share of an allocated cash prize Once participants start playing, their quiz sessions must not be lost especially if all previous questions were answered correctly. The application owner wants to ensure that 99% of quiz sessions are maintained (up to 4.95 million sessions) until the last answer has been successfully recorded Based on this scenario, when is It best time within this software and system update project to analyze and assess performance risks?

• A. After design phase but prior to implementation phase
• B. During user acceptance testing and subsequent regression testing
  :,
• C. Revisited overthe course of the developmentLifecycles
• D. During the requirements phase

The application owner wants to ensure that 99% of quiz sessions are maintained (up to 4.95 million sessions) until the last answer has been successfully recorded Before your team begins testing, the team needs to present the performance test plan to technical stakeholders Which of the following sets of plan attributes would you recommend be included in this presentation?
i.Sales has indicated that quiz events for Sponsor A offering $65,000. Sponsor B offering $45,500. Sponsor C offering $25,000 will be taking place during the first week of performance testing.
ii. Simultaneous session tests are focused on the backend. and are not end-to-end. Variability in user behavior, mobile devicesand mobile communications introduces session drop opportunities outside application control.
Using load generators located
in 5 high availability data centers in North America will ensure session drops are most likely caused by application issues, thus allowing us to isolatethe root cause of any concurrency issues that arise iii.Test scripts based on replaying recorded communication will take 30 hours each to write and test due to the extensive parameterization required to respond to quiz questions Development has agreed to share client code that can be scripted to authenticate and respond to quiz questions automatically. The fully programmed script will likely take 18 hours each to write and test Fully programmed scripts will utilize the identical communications stack of the actual client avoiding missed communication nuances.
iv The U S Federal Trade Commission has recently sued SmartyBogusFauxApp and OutSmartMeexample com over promises of prizes andunreliability v The upgrade being tested was paid for by the latest round of venture funding Supporting 5 million users is requirement thatwas a condition of their funding.
