Which of the following Is a valid reason for aggregating performance test results?

1. A. Business stakeholders work with detailed technical status indicators when evaluating an application's performance
2. B. Business stakeholders can evaluate an application's overall performance status.
3. C. Technical stakeholders work with aggregated data when isolating causes of performance problems
4. D. Technical stakeholders work with detailed technical status indicators when evaluating an application's performance

Correct Answer: A

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?

1. A. During the actual quiz, users logon gradually but play simultaneousl
2. B. The load injection of quiz responses will not ramp u
3. 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%
4. 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
5. 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
6. 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
7. G. There is a 10% chance that the production system will not restored in time for a quiz.

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?

1. A. 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.i
2. B. Simultaneous session tests are focused on the backen
3. C. and are not end-to-en
4. D. Variability in user behavior, mobile devicesand mobile communications introduces session drop opportunities outside application contro
5. E. 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 ariseii
6. F. 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 automaticall
7. G. 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 andunreliabilityv 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.

An essential operational profile you identified is the quiz participant Your operational profile discovery efforts have yielded a number of profile attributes / 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.
Which of thefollowingIs a proper load profilefor thequiz participants?

1. A. 240.000,000 question responses per hour
2. B. Steady ramp-up of quiz response transactions from one million until the design maximum is reached within the first three questions.The maximum is sustained until question twelve
3. C. Stepped ramp-up of quiz response transactions from one million increasing by a one million after each question until the design maximum is reached.The minimum is sustained until question twelve.
4. D. Maximum number of planned concurrent quiz responses will occur at the first question with a steppedramp-down after each question.The size of each step and the final number of nearly simultaneous quiz responses are random values within historical ranges observed over the last three

During your conversations with stakeholders you determine that an essential transaction was the quiz participant's responses to questions As you prepare to speak to stakeholders regarding their test objectives for this transaction, you develop a collection of prepared questions to ask them.
Which question is best aligned to the types of questions recommended for gathering test objectives information from stakeholders?

1. A. How long should it take before the user becomes aware that their last response was incorrect'
2. B. What are the targeted percentages of correct responses for each of the questions asked during a quiz event?
3. C. What are the targetfor CPU utilization and memory consumption for the web services platforms receiving question responses?
4. D. What is the projected participation growth rate over the next nine months?

Correct Answer: C
