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.

Definitely spike testing! High load for short bursts.

I feel like this is definitely not endurance testing, but I can't quite recall the differences between spike and load testing.

I’m a bit confused; I thought concurrency testing was about handling multiple users at once, but this question seems to focus on the timing of the load.

I remember practicing with load testing scenarios, but this seems more specific to sudden increases in users, so maybe it's spike testing?

I think this might be spike testing since it focuses on short bursts of high load, but I'm not entirely sure.
