CGOA Gitops Patterns Practice Question
You are implementing progressive delivery using Flagger. After a Canary resource is defined, which metric is most critical for Flagger to automatically rollback a deployment during a blue/green shift?
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 success rate and latency metrics
Flagger uses analysis templates to evaluate Prometheus metrics; if the error rate or latency thresholds are exceeded, it triggers a rollback.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Pod CPU usage
Why it's wrong here
CPU usage is a resource metric, but Flagger typically focuses on service-level objectives like latency and error rates for rollbacks.
- ✗
Number of running replicas
Why it's wrong here
This relates to deployment scale, not the success of the traffic shift.
- ✓
Request success rate and latency metrics
Why this is correct
Flagger specifically monitors service mesh or ingress metrics to decide if a traffic shift is safe.
- ✗
Git commit hash parity
Why it's wrong here
Git commit parity is for synchronization, not for behavioral traffic analysis.
