Task
In namespace monitoring, Pod metrics-pod is using ServiceAccount wrong-sa and receiving authorization errors.
Multiple ServiceAccounts, Roles, and RoleBindings already exist in the namespace:
- ServiceAccounts:
monitor-sa,wrong-sa,admin-sa - Roles:
metrics-reader,full-access,view-only - RoleBindings:
monitor-binding,admin-binding
Requirements
- Identify which ServiceAccount/Role/RoleBinding combination has the correct permissions
- Update Pod
metrics-podto use the correct ServiceAccount - Verify the Pod stops showing authorization errors
Hint: Check existing RoleBindings to see which ServiceAccount is bound to which Role.
What this tests
Wire up configmaps, secrets, service accounts, RBAC, securityContext, and resource limits. On the CKAD exam, Application Environment, Configuration and Security tasks are graded purely on what you build in the cluster — not multiple choice — so the only way to get faster is to do them on a real cluster against a clock.
Practice it for real
prepium.sh drops you into your own isolated Kubernetes cluster in the browser — no install, no credit card. You solve the task in a real terminal, hit validate, and a programmatic checker scores exactly what you got right and wrong (with partial credit). The canonical solution unlocks after you attempt it, so you learn the fast, exam-ready way to do it.
