Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Integration with Linux security modules (Seccomp, AppArmor, SELinux)
Why this is correct
Container runtimes interface with LSMs to enforce system call filtering and access controls.
- ✗
Management of Kubernetes RBAC roles and cluster permissions
Why it's wrong here
RBAC is handled by the Kubernetes API server auth modules.
- ✓
Namespace isolation (PID, network, mount, user namespaces) for containers
Why this is correct
Namespaces isolate container processes, network stacks, and mount points from the host and other containers.
- ✗
Automatic deployment of service mesh sidecar proxies
Why it's wrong here
Sidecar injection is handled by mutating admission webhooks in the Kubernetes control plane.
- ✗
Automatic generation of Kubernetes Ingress TLS certificates
Why it's wrong here
Ingress certificates are managed by ingress controllers or cert-manager, not container runtimes.
