[All CTAL-TTA Questions]

Which of the following is a valid reason for including performance testing in a test approach?

ATo reduce the threat of code insertion into a web page which may be exercised by subsequent users.

BTo evaluate the system's tolerance to faults in terms of handling unexpected input values.

CTo mitigate the risk of long response times to defects reported by users and/or customers.

DTo evaluate the ability of a system to handle increasing levels of load.

Show Suggested Answer

Suggested Answer: D

Performance testing is a key part of ensuring that a system can handle the expected load and perform well under high demand. This type of testing is designed to test the robustness, speed, scalability, and stability of the system under a given workload. It is not primarily concerned with security threats such as code insertion (Option A), nor with fault tolerance in terms of unexpected input values (Option B), nor with the speed of addressing user-reported defects (Option C), although these may be tangential benefits. Performance testing is focused on ensuring that the system meets performance criteria and can handle increasing loads without degradation of service, which is essential for providing a good user experience and for the system's reliability.

I practiced a similar question where we had to identify the purpose of performance testing, and I think it was about evaluating system load capabilities.

I think option D makes the most sense since performance testing is all about load handling, right?

Okay, the key steps seem to be installing chrony, configuring the NTP server, enabling and restarting the chronyd service, and then setting the timezone. I think I can handle this.
