[All CT-PT Questions]

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

AResponse time will gradually improve over a period of time.

BResponse time will be slow under significant load levels.

CError logging will decrease.

DThe size of the database will gradually decrease.

Show Suggested Answer

Suggested Answer: B

When system resources (e.g., CPU, RAM, I/O) are oversaturated, the system becomes overloaded, leading to increased response times and poor application performance.

Option A (Gradual improvement of response time) is incorrect because performance degrades under heavy load.

Option C (Error logging decreases) is unlikely; in most cases, errors increase when systems reach their limits.

Option D (Database size decreases) is unrelated to performance saturation.

I agree with Vicente, oversaturation of system resources will definitely slow down response time.

B) Response time will be slow under significant load levels. Yup, that's the one. I can practically feel the system groaning under the pressure just thinking about it.

C) Error logging will decrease? I guess if the system crashes and burns, there won't be any errors to log. But that's not exactly the best outcome, is it?

A) Response time will gradually improve over a period of time? Umm, no. That's not how it works. Unless the system is magical, it's going to struggle under heavy loads.

Wow, D) The size of the database will gradually decrease? That's definitely not the result of oversaturation. I think someone needs to go back to performance testing 101.

B) Response time will be slow under significant load levels. This is exactly what we would expect to see when system resources are oversaturated during performance testing.
