Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Enable anonymous authentication on the kubelet secure port.
Why it's wrong here
Anonymous access increases exposure.
- ✗
Run kubelet containers in privileged mode.
Why it's wrong here
Kubelet runs directly on the host, not as a container, and privileged mode should be avoided.
- ✓
Configure kubelet authorization mode to Webhook.
Why this is correct
Webhook authorization ensures RBAC rules govern kubelet API calls.
- ✗
Set authorization.mode to AlwaysAllow.
Why it's wrong here
AlwaysAllow bypasses authorization checks.
- ✓
Disable the unauthenticated read-only port by setting readOnlyPort to 0.
Why this is correct
Disabling the read-only port stops unauthenticated local data exposure.
