EX280 User And RBAC Management Practice Question
An administrator is troubleshooting a service account named 'cicd-bot' in the 'ci-cd' namespace that is failing to read pods in the 'production' namespace, despite a RoleBinding existing. Upon inspection, the RoleBinding references a Role (not a ClusterRole) in the 'ci-cd' namespace. Why is the service account failing to access resources in 'production'?
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
✓
Standard Roles are namespace-scoped and cannot grant permissions to resources in another namespace
A standard Role and RoleBinding are strictly namespace-scoped. A Role in namespace A cannot grant permissions to resources in namespace B. To grant cross-namespace access, a ClusterRole must be used with either a RoleBinding (in the target namespace) or a ClusterRoleBinding.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Standard Roles are namespace-scoped and cannot grant permissions to resources in another namespace
Why this is correct
Correct. Namespaced Roles only apply to the namespace in which they are created.
- ✗
Roles cannot reference service accounts as subjects unless they are in the openshift-infra namespace
Why it's wrong here
Incorrect. Service accounts from any namespace can be subjects in RoleBindings.
- ✗
Service accounts cannot use RoleBindings, they require ClusterRoleBindings for any authorization
Why it's wrong here
Incorrect. Service accounts can be subjects in standard RoleBindings.
- ✗
The service account token has expired and must be manually regenerated using oc adm ca
Why it's wrong here
Incorrect. OpenShift automatically manages and mounts tokens for service accounts.
