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.

Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Assign RBAC roles to all developers to prevent image pull actions.
Why it's wrong here
This prevents pulling, but does not enforce image source compliance.
- ✗
Modify the Kubelet configuration files directly on the nodes.
Why it's wrong here
Kubelet configuration cannot be used to restrict image source at the cluster level.
- ✗
Configure the Azure CLI to deny access to unauthorized ACR registries.
Why it's wrong here
This is a client-side control and does not prevent the deployment via K8s APIs.
- ✓
Use the Azure Policy add-on for Kubernetes to enforce an 'Allowed Container Images' policy.
Why this is correct
This acts as an admission controller to block non-compliant deployments.
