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
✓
Readiness probe
Readiness probes determine whether a pod is ready to receive traffic; only when the probe succeeds is the pod added to service endpoints.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Startup probe
Why it's wrong here
Startup probes check if the application has started; they do not manage ongoing readiness.
- ✗
Liveness probe
Why it's wrong here
Liveness probes indicate whether the container is running; they do not control traffic routing.
- ✗
Resource limits
Why it's wrong here
Resource limits constrain CPU/memory usage, not health checks for traffic routing.
- ✓
Readiness probe
Why this is correct
Readiness probes indicate when a pod is ready to serve traffic; Kubernetes only sends traffic to pods with a successful readiness probe.
