How do you validate that the EPD Protocol Pilot meets its defined performance targets?

• A. Measure latency only.
• B. Ignore metrics.
• C. Measure only CPU usage.
• D. Compare measured metrics (latency, throughput, loss rates, CPU usage) against targets and perform regression tests.

Answer: (D)

Validation of performance targets comes from measuring a set of key metrics and checking them against predefined targets, then confirming stability over time with regression testing. For the EPD Protocol Pilot, you should track latency, throughput, loss rates, and CPU usage because together they reveal how fast responses are, how much load the system can handle, how reliable the data transmission is, and how efficiently resources are used. By comparing these measured metrics to the specified targets, you can determine if the pilot meets expectations. Running regression tests after any change ensures that improvements or fixes don’t inadvertently cause performance to degrade again; you re-measure the same metrics under representative conditions and verify they stay within targets. This approach prevents missing issues that could arise if you only watch a single metric (like latency or CPU usage) or if you skip metric checks altogether.
