NEW QUESTION 1
You have beenasked to test the performance ofa 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.
An essential operational profile you identified is the quiz participant Your operational profile discovery efforts have yielded a number of profile attributes A quiz participant will answer twelve questions if they manage to answer the first eleven correctly Every user is made aware of a new question nearly simultaneously.The quiz user has limited time to respond using a mobile application.They are unable to respond to subsequent questions after they incorrectly answer a question. However, the quiz participant continues to see new questions even though they may have responded incorrectly to a previous question. If they manage to answer all twelve questions correctly, the quiz application notifies them that they have tentatively won (subject to formal verification) an equal share of a cash prize of an amount set for the particular quiz event In addition to this individualized interaction, a broadcast video stream is presented in the quiz app providing entertaining commentary, quiz event coordination event status and answer explanations.
Given this information, what is missing to construct the operational profile for the quiz participant?

• A. The network bandwidth requirements of the video stream intermissions between questions is unknown.The network bandwidth requirements of the video stream intermissions between questions is unknown
• B. No survey results from past quiz winners that explore how they won No survey results from past quiz winners that explore how they won.
• C. The quiz response time limit is not specified.The quiz response time limit is not specified
• D. The design maximum number of users within quiz participant user class is unknown.The design maximum number of users within quiz participant user class is unknown

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 promised a 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.
You performed 100 test runs that provided 5 million virtual concurrent users.You have measurements of participant concurrency at the last question for each test run In your analysis, you order all the concurrency test results by measured concurrency value from best to worst.You determine 85%. 90%. 95% and 100% values by selecting the 85th. 90th. 95th and 100th (last and worst) measured values by counting list positions starting from the best value going towards the worst until you reach the desired list position (ex. 85). Keep in mind, the results in lower list positions are as good or better than the results chosen for reporting.
After analyzing the results of the performance tests, you present the following results 85% 4.92 million valid concurrent users
90% 4.90 million valid concurrent users
95%: 4.0 millionvalid concurrent users
100%. 3.8 million valid concurrent users
Based on these results, what should you report to thestakeholders?

• A. The performance tests clearly have failed to produce a realistic and compatible load.The results should confirm the test oracle in that the 99% of five million participants concurrency objective has been achieved.If the performance test plan had worked correctly, the reported values should have been 85% 4.95, 90% 4.95, 95% 4 95 and 100% 4.95 million valid concurrent users.
• B. These results clearly show that the system update successfully supports 99% of five million participants
• C. Four samples from the first fifteen ordered test results are presente
• D. The system update performed much worse than what is presented her
• E. The system update has failed to meet the 99% of five million participants concurrency objective.
• F. If we pick 85 out of 100 test runs as the minimum level of reliability, thesystem update does not reliabilitymeet the 99% of five million participants concurrency target,However not all results are as bad as these

Answer: A

NEW QUESTION 4

• A. Record insertions align with transaction objectivei
• B. Component failure within the system under testii
• C. Load generator produces low load leveli
• D. Database log remains synchronized with load generators time source
• E. Virtual users authenticate with distinct IDs
• F. i, iii true ii, iv, v false
• G. i
• H. iii true
• I. iv, v false
• J. ii, v true i, iii, iv false
• K. iv, v true i, ii, iii false

Answer: C

NEW QUESTION 5
Which tool is ideally the only source of execution burden experienced by the system under test?

NEW QUESTION 9
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
