Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Request latency (P99)
Latency and request rates (throughput) are the primary indicators of performance issues.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Request latency (P99)
Why this is correct
Helps identify slow services.
- ✗
Number of active connections
Why it's wrong here
Less useful than RPS/Latency for general bottleneck identification.
- ✗
CPU usage of the sidecar
Why it's wrong here
Resource usage is useful but not the primary indicator of service-to-service performance.
- ✗
Memory usage of the application
Why it's wrong here
App memory doesn't explain network bottleneck issues.
- ✓
Request rate (RPS)
Why this is correct
Helps identify traffic volume and potential saturation.
