You are managing a project that is testing a system that manages a newly redesigned jet engine for heavy aircraft. Given the fact that this engine is specifically engineered to reduce noise, it is important that the software maintains enough thrust for lift for a period of 5 minutes without exceeding 87.5dB. The software must achieve this independent of other internal systems such as fuel or navigation management.
Given the risk for the ability of the aircraft to meet the noise abatement regulations while still being able to fly, when is the optimum time in the software lifecycle to apply the performance testing?

• A.Preferably during system integration testing
• B.Preferably during each phase in the lifecycle
• C.Preferably at the end of system testing
• D.Preferably at the end of unit testing

You have run a load test. When examining the metrics, you see that the virtual users experienced many timeouts and excessive wait times. The system throughput metrics exceeded expected results, even during peak times.
Based on your analysis, what conclusion should you draw?

• A.Virtual users are exhibiting impatient behavior.
• B.New test data is needed.
• C.Processing speed is too slow.
• D.Network infrastructure should be investigated.

Which of the following is a best practice to include in performance test scripts when verifying results?

• A.Increase the number of scripts executed to provide greater coverage.
• B.Hold the development team accountable for system performance.
• C.Verify that correct information was added to the database.
• D.Add transaction timers to collect response times.

What is the primary purpose of a load generator?

• A.Create a steady and consistent background load on the system
• B.Record and analyze the behavior of the system as it is executing the prescribed tests
• C.Support root cause analysis when performance degradation is encountered
• D.Simulate user behavior in accordance with the defined operational profile

Which of the following is a typical performance risk associated with mainframe architectures?

• A.Slow hard disk speed
• B.Inconsistent loads when accessed via APIs
• C.Lack of RAM
• D.Misconfigured host machine
