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 it’s more about simultaneous users rather than sudden spikes.

I remember practicing with load testing questions, but this seems more specific to handling bursts of traffic, 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.
