Correct answer & explanation

Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Review the OperatorHub catalog source logs in openshift-marketplace.
Why it's wrong here
openshift-marketplace hosts Operator catalog pods, unrelated to node configuration daemons.
- ✓
Check the logs of the machine-config-daemon pods in the openshift-machine-config-operator namespace.
Why this is correct
The machine-config-daemon runs on every node and logs configuration application failures.
- ✗
Run 'oc adm node-logs --role=worker' to view kernel panic messages.
Why it's wrong here
The 'oc adm node-logs' command exists for system logs, but machine-config-daemon logs are found via pod log inspection.
- ✗
Inspect the Cluster Version Operator logs in openshift-cluster-version.
Why it's wrong here
CVO logs show cluster release upgrades, not individual node-level MCO daemon execution errors.
