[All CTFL-PT_D Questions]

If Emily is conducting a performance test to determine that a system exposed to a load can respond to a high number of concurrent users during short periods of time that occur on specific days and at specific times, and then return to a stable state.

Suggested Answer: B

Spike testing involves subjecting a system to a significant increase in load for short periods of time to determine if it can handle sudden spikes in traffic. Emily's scenario of testing a system's response to a high number of concurrent users during specific periods and then returning to a stable state fits the description of spike testing.

Concurrency testing sounds familiar, but I feel like that’s more about simultaneous users rather than the sudden load Emily is testing for.

I remember practicing with a question about load testing, but this seems more specific to handling bursts of users, so maybe it's spike testing?

I think this might be spike testing since it focuses on sudden increases in load, but I'm not entirely sure.

I think the answer is B, spike testing. The key details are the system being exposed to a high number of users during specific time periods, and then returning to a stable state. That's exactly what spike testing is meant to evaluate.

Hmm, I'm leaning towards concurrency testing. The question specifically mentions the system handling a high number of concurrent users, which is what concurrency testing is all about.

I'm a bit unsure on this one. The question talks about the system returning to a stable state, which could also be a characteristic of load testing. I'll need to think this through carefully.

This seems like a classic case of spike testing. The question mentions the system being exposed to a high number of concurrent users during specific time periods, which is exactly what spike testing is designed to assess.

I think it's a combination of load testing and concurrency testing. The system needs to handle both the high load and the large number of concurrent users.

Definitely spike testing. The question mentions high numbers of concurrent users during specific time periods, which is exactly what spike testing is all about.
