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 new clusterrole storage-reader --permissions=pv:get,list
Why it's wrong here
'oc new' is not a valid subcommand for creating cluster roles.
- ✗
oc create role storage-reader --cluster --verb=get,list --resource=persistentvolumes
Why it's wrong here
The 'oc create role' command creates namespace-scoped roles; 'clusterrole' must be used for cluster-wide roles.
- ✗
oc adm create-role storage-reader --cluster-wide --verbs=get,list --resources=pv
Why it's wrong here
This subcommand syntax is invalid.
- ✓
oc create clusterrole storage-reader --verb=get,list --resource=persistentvolumes
Why this is correct
This command correctly provisions a cluster-scoped role for persistent volumes.
