NR. 19 Which of the following performance tests could be best considered to be the opposite to the endurance test when comparing the duration of thetests?

NR. 20 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 storesserving 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.
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.
The average quiz event duration when measured from when the first question is presented to the last answer is reviewed is fifteen minutes. Over the fifteen minutes, twelve questions are presented to quiz participants. After making the following assumptions:
1. Questions must be responded to within a four second window;
2. Question responses will be sent evenly across this window of time (resulting in an average responder time of two seconds);
3. The designed maximum number of concurrent users will attempt the first question;
4. There will be no functional issues when handling the load.
5. The average time from response reception to database commitment is 1000 milliseconds under maximum concurrent usage.
What is the approximate maximum average systemthroughput if that assumptions hold?

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.

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?
