EX280 User And RBAC Management Practice Question
An administrator needs to ensure that no pod in the 'secure-zone' namespace can run with root privileges or use host networking. Which mechanism natively enforces this across all pods in the namespace?
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.
Correct answer & explanation
✓
Assigning a restrictive SecurityContextConstraints (SCC) policy to the service accounts running the pods
SecurityContextConstraints (SCCs) control pod security attributes. By assigning a restrictive SCC (like 'restricted') to the service accounts in the namespace, root execution and host networking are prevented.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Setting container securityContext in every deployment manually
Why it's wrong here
While manual container settings work, SCCs enforce this cluster/namespace-wide automatically.
- ✓
Assigning a restrictive SecurityContextConstraints (SCC) policy to the service accounts running the pods
Why this is correct
SCCs enforce constraints on runAsUser, hostNetwork, capabilities, and privileged flags.
- ✗
Configuring a NetworkPolicy to block root network namespaces
Why it's wrong here
NetworkPolicies handle Layer 3/4 packet filtering, not container security run-as users or host namespaces.
- ✗
ResourceQuota limits on security capabilities
Why it's wrong here
ResourceQuotas manage resource quantities, not security contexts.
