   A performance acceptance test for a new document management system has been executed. The results show that the average response time for uploading a document is 4 seconds, but the 95th percentile is 12 seconds. The acceptance criterion states: 'The average upload time must be less than 5 seconds.' What is the correct conclusion?

   • AThe system fails because the 95th percentile shows that some users experience very slow uploads.
   • BThe system fails because the 95th percentile is too high, indicating a performance problem.
   • CThe system passes because the average response time is below 5 seconds.
   • DThe test is inconclusive because the team did not measure the number of concurrent users.

   After executing a performance acceptance test, the team has the following results: average response time = 1.8 seconds, 95th percentile = 3.2 seconds, and error rate = 0.5%. The acceptance criterion states: '95% of requests must complete within 2 seconds, and the error rate must be below 1%.' What is the correct conclusion?

   • AThe system passes the acceptance test because the average response time is below 2 seconds and the error rate is below 1%.
   • BThe test is inconclusive because the team did not record the number of concurrent users during the test.
   • CThe system passes because the error rate is below 1%, and the response time is acceptable for a peak load test.
   • DThe system fails the acceptance test because the 95th percentile response time exceeds 2 seconds.

   During the execution of performance efficiency acceptance tests, what is the primary purpose of collecting measurements?

   • ATo verify that the system is functioning correctly from a functional perspective.
   • BTo provide a baseline for future performance tuning activities.
   • CTo identify all defects in the system before release.
   • DTo gather data that can be compared against the acceptance criteria to determine if the system meets performance requirements.
