NEW QUESTION 2
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. 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
• 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. 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.

Answer: B

NEW QUESTION 3
Which of the situations test adheres to general performance testing principles?

NEW QUESTION 7
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.
Before your team begins testing, the team needs to present the performance test plan to business stakeholders Which of the following sets of plan attributes would you recommend be part of this presentation?

• A. During the actual quiz, users logon gradually but play simultaneousl
• B. The load injection of quiz responses will not ramp u
• C. therefore nearly 5 million quiz responses will need to be generated in a 4 second time frame with no opportunity to reach steady state.Test plans have been discussed with Operations Development and Data Center representatives and we believe the tests will tax the quiz application consistent with actual use.The JMeter monitoring system has been tuned however, with 5 million service requests over 4 seconds there is concern that the services queue measurements may be off by 25%
• D. There is a less then10% chance of missing a scheduled quiz session due to performance test activities, which will likely cost the company $50,000 in lost sponsor revenue and brand damage To avoid this risk, we are scheduling Operations and Development representatives to be available during test execution We will require that the RAID 5+1 LUNs associated with the database server cluster be broken at 22 30 and the RAID 5+1 LUNs restored, ensuring the offline set mirrors back to the RAID 5 set that was under test, at 03:00
• E. Since the client uses an asynchronous REST web services based sessions back to the QUZRAC services cluster, the loadprofile will consist of virtualusers running programmed load scripts based in C# that will randomly select the correct answer following a normal distribution thus modeling the typical success distribution among users The strict 4 second cap on user responses will translate into think times that are randomly selected between 1/2 second and just under 4 seconds using a uniform distribution
• F. If the quiz application drops more than 1% of quiz sessions, users will likely write bad reviews on app stores and other gaming sites Performance tests will verify that system can support at least 4 95 million users Planned tests, which include the simultaneous sessions test, will cost $350,000 Since only two quizzes are scheduled a day, performance tests on the production system during the "down' times should be representative of what users experienc
• G. There is a 10% chance that the production system will not restored in time for a quiz.

Answer: C

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
In order to avoid cooperation among quiz participants, the answers to the multiple choice questions are listed randomly Confidence in the game's fairness requires that a registered user originate from only one quiz client device Every user must respond over the same short window of time in order to avoid external assistance and learning the official answer before responding.Only participants who respond correctly may answer the next question Any activity that appears to violate expected behavior of a rule-following participant will cause the client session to be rejected.
You are currently preparing test scripts to function as a quiz participant.
What input data type is most critical for the test script to incorporate to ensure that the concurrency objective will be properly tested?

• A. In order to property test theconcurrency objective,the test script must answer each trivia question with the same answer as every other virtual user
• B. In order to property test the concurrency objective, the test script must provide a random password to the application's login system
• C. In order to properly test the concurrency objective, the test script must present a unique user name to the application's login system
• D. In order to properly test the concurrency objectivesthe test script must supply the system provided unique session ID with each answer provided

Answer: B

NEW QUESTION 12
How does service virtualization contribute to the performance test environment?

• A. Service virtualization allows the load generators to produce more load per virtual instance.
• B. Service virtualization enables the system under test to avoid functional error conditions caused by a necessary service being unavailable at the time of the performance test.
• C. Service virtualization enables load balancers to operate in a distributed environment thereby creating a realistic emulation of a production environment when available system under test equipment is inferior to production.
• D. Service virtualization allows the database to perform as if it were loaded with a data set many times larger than is actually loaded
