EX280 User And RBAC Management Practice Question
An administrator needs to grant a developer named 'alice' read-only access to all pods specifically within the 'development' namespace. Which command should be used to accomplish this while following the principle of least privilege?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
oc create rolebinding alice-view --clusterrole=view --user=alice -n development
The view ClusterRole provides read-only access to most resource types within a project. Binding it via a RoleBinding in the specific namespace limits access strictly to that namespace.
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 create role alice-view --verb=get,list,watch --resource=pods --user=alice -n development
Why it's wrong here
While creating a custom role works, OpenShift provides standard predefined roles like 'view' which should be reused when possible.
- ✗
oc adm policy add-cluster-role-to-user cluster-admin alice
Why it's wrong here
Incorrect. This grants cluster-admin privileges cluster-wide, far exceeding read-only access.
- ✗
oc create clusterrolebinding alice-view --clusterrole=view --user=alice
Why it's wrong here
Incorrect. A ClusterRoleBinding grants cluster-wide access, which violates the requirement to restrict access to the development namespace.
- ✓
oc create rolebinding alice-view --clusterrole=view --user=alice -n development
Why this is correct
Correct. This binds the view cluster role to user alice in the development namespace via a RoleBinding.
