Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

✓
In the kube-apiserver static pod manifest file under '/etc/kubernetes/manifests/kube-apiserver.yaml'.
Why this is correct
The API server configuration file defines active admission plugins.
✗
In the CoreDNS deployment spec.
Why it's wrong here
CoreDNS handles cluster internal name resolution, unrelated to admission control.
✗
In the kubelet configuration file on each worker node.
Why it's wrong here
Kubelet manages node-level container lifecycles, not cluster-wide admission control.
✗
In the cluster-wide ConfigMap named 'kube-system/cluster-admission'.
Why it's wrong here
Admission plugins for the core API server are set via command-line flags, not a ConfigMap.
