Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Reinstall the entire cluster storage operator.
Why it's wrong here
Storage operators have no impact on network routing or routes.
- ✓
Check that the Route hostname resolves correctly via DNS to the cluster router IP.
Why this is correct
External DNS must point the route hostname to the ingress router load balancer/IP.
- ✓
Verify that the referenced Service has active endpoints.
Why this is correct
Zero endpoints cause 503 errors on routes.
- ✓
Inspect the Ingress controller operator logs for routing errors.
Why this is correct
Router logs indicate if requests are reaching the HAProxy instance and failing.
- ✗
Modify the cluster kube-apiserver certificates.
Why it's wrong here
API server certificates do not affect route data plane traffic.
