During designdiscussions the performance testteam observed that database stored procedures for several popular use casesmay be badly coded.Which of thefollowing common performance failures would bestconfirm the team's confirmwas justified?

• A. Degraded response over time
• B. Inadequate or graceless error handling under heavy or over-limit load
• C. Slow response under all load levels
• D. Slow response fader moderate-to-heavy load levels

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. 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
• B. Four samples from the first fifteen ordered test results are presented. The system update performed much worse than what is presented here. The system update has failed to meet the 99% of five million participants concurrency objective.
• C. 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.
• D. These results clearly show that the system update successfully supports 99% of five million participants

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

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

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 properly test the concurrency objectivesthe test script must supply the system provided unique session ID with each answer provided
• C. In order to property test the concurrency objective, the test script must provide a random password to the application's login system
• D. In order to properly test the concurrency objective, the test script must present a unique user name to the application's login system
