What is the purpose of a Kubernetes namespace?

To isolate network traffic between pods using network policies.

To define the resource limits and quotas for all pods in the cluster.

To provide a scope for naming and organizing Kubernetes resources within a cluster.

To assign a unique IP address to each pod in the cluster.

A stateful application running in a Kubernetes cluster needs to persist data across pod restarts and be available to any pod that is scheduled on the same node. The cluster uses dynamically provisioned storage. Which storage object should be used?

PersistentVolumeClaim with a StorageClass that provisions a ReadWriteOnce volume

A hostPath volume pointing to a node directory

A ConfigMap mounted as a volume

A team runs a stateful application on Kubernetes with a PersistentVolumeClaim (PVC). They need to ensure that the data is replicated across multiple availability zones to protect against zone failures. Which approach should they use?

Use an emptyDir volume with multiple replicas

Use a StorageClass that supports zone-redundant storage

Use a ConfigMap to store the data

Use a hostPath volume on each node

Part of the Container and Kubernetes Security domain, which makes up ~11% of our current practice bank. GIAC (SANS) does not publish an official question count, but from its 120-minute exam (~50–80 total, ~6–9 in this domain), expect 6–9 from this objective — we provide 49 practice questions to prepare you well beyond it.
