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

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?

Options:

A.

How long should it take before the user becomes aware that their last response was incorrect'

B.

What are the targeted percentages of correct responses for each of the questions asked during a quiz event?

C.

What are the targetfor CPU utilization and memory consumption for the web services platforms receiving question responses?

D.

What is the projected participation growth rate over the next nine months?

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?

Options:

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 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.

D.

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
