Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
oc get users --role=cluster-admin
Why it's wrong here
The 'oc get users' command does not accept a role filter flag.
- ✗
oc adm who-is cluster-admin
Why it's wrong here
'who-is' is not a valid OpenShift CLI subcommand.
- ✗
oc describe clusterrole cluster-admin
Why it's wrong here
Describing the ClusterRole shows its rules, not the subjects bound to it via bindings.
- ✓
oc get clusterrolebindings cluster-admin -o jsonpath='{.subjects}'
Why this is correct
Inspecting the subjects of the cluster-admin ClusterRoleBinding reveals all users and groups with cluster-admin access.
