Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
In the IngressController custom resource spec
Why this is correct
Wait, IngressController configures router parameters, but pod probes are strictly workload properties. (Correction: Option A is correct, container probes belong in the pod template).
- ✓
In the Deployment pod template spec under livenessProbe and readinessProbe
Why this is correct
Probes are defined in the container specifications inside the workload object (Deployment/Pod).
- ✗
In the Service specification under healthCheckNodePort
Why it's wrong here
healthCheckNodePort is only used for external load balancer health checks, not container readiness/liveness.
- ✗
In the DNS operator configuration
Why it's wrong here
DNS operator has no visibility into pod probes.
