CKS Minimize Microservice Vulnerabilities Practice Question
Which flag enables the PodSecurity admission plugin in kube-apiserver?
⚠ Common exam trap
Candidates often confuse enabling a feature gate with enabling an admission plugin; the trap here is that candidates confuse `--feature-gates=PodSecurity=true` (which only makes the plugin available) with `--enable-admission-plugins=PodSecurity` (which actually activates it), or they mistakenly use the deprecated `--admission-control` flag.

Correct answer & explanation
✓
--enable-admission-plugins=PodSecurity
The PodSecurity admission plugin is enabled in kube-apiserver by passing the `--enable-admission-plugins=PodSecurity` flag. This flag activates the built-in Pod Security Admission (PSA) controller, which replaced the deprecated PodSecurityPolicy (PSP) in Kubernetes v1.25. The plugin enforces the Pod Security Standards (baseline, restricted, privileged) at the namespace level based on labels.
