CompTIA Data+ DA0-002 (V2) Practice Question

Stress testing intentionally drives a system beyond its normal operating limits to expose bottlenecks, failures, and recovery behavior under extreme conditions. Because the team must confirm that the pipeline keeps functioning when input volume spikes to five times the typical load, a stress test is the most appropriate method. A load test would measure performance at expected or slightly elevated volumes, not at overload conditions. User acceptance testing checks that outputs meet business needs but does not evaluate capacity. Creating documentation such as a data dictionary improves governance and explainability but does not test runtime performance.
