Show Suggested Answer

Suggested Answer: D

Spike testing is a type of performance testing that evaluates how a system responds to sudden, extreme increases or decreases in load. It is designed to simulate unexpected surges in user activity or workload, such as flash sales, viral events, or cyberattacks.

Option A (Gradual load increase testing) describes load testing, not spike testing.

Option B (Handling expected peak load) describes stress testing, which pushes the system to or beyond its limits but does not focus on sudden changes.

Option C (Meeting future efficiency requirements) relates to capacity planning rather than spike testing.

Spike testing helps to identify system bottlenecks, resource allocation issues, and performance degradation when traffic surges unexpectedly.

Wow, this is a tough one! I was tempted to go with option A, but I think B is the most accurate description. Spike testing is all about pushing the limits, not just gradual load increases.

Option D sounds good to me. Spike testing is about the system's ability to respond to quick and extreme changes in load, not just gradually increasing loads.
