You are heading the testing effort for a system that manages the air/fuel ratio of direct-injection fuel devices built specifically for high-altitude rescue helicopter engines. At altitude, the system must be able to perform in order to make enough air/fuel ratio adjustments per millisecond between fuel and both an on-board source and available ambient air in order to prevent an engine stall due to oxygen starvation. The system is following a sequential development lifecycle.
For this safety-critical software, when is the appropriate point in the lifecycle to identify and define the performance goals?

• A.At the very beginning of the project during the concept stage
• B.After test readiness has been achieved, but before system testing starts
• C.During the requirements phase when the business stakeholders have the opportunity to agree
• D.During the software design phase when the requirements are set and the design is being defined

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

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

What is typically the result of oversaturation of system resources during performance testing?

• A.The size of the database will gradually decrease.
• B.Response time will gradually improve over a period of time.
• C.Error logging will decrease.
• D.Response time will be slow under significant load levels.

Which of the following should be a key part of your test acceptance criteria in your performance test plan?

• A.Describing the system under test in order to provide context to the metrics
• B.Highlighting any technical differences in the hardware between the test environment and the production environment
• C.Convincing technical and business stakeholders to provide realistic performance goals for the regional servers
• D.Documenting previously baselined performance metrics in order to compare these to the new performance measurements

Which of the following can provide measurements for both individual and aggregated elements within a single performance test?

• A.Nested transactions
• B.Aggregated metrics
• C.Measuring underlying transactions
• D.Process optimization tracking
