Google PCA Manage implementation of cloud architecture Practice Question
A developer needs to deploy a stateful application that requires persistent storage across pod restarts in Google Kubernetes Engine. Which resource should they use?
⚠ Common exam trap
Test-takers frequently confuse ephemeral volumes (EmptyDir) with persistent storage, or assume ConfigMaps/Secrets can store application data, when in fact they are for configuration and secrets only.
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
✓
PersistentVolumeClaim
A PersistentVolumeClaim (PVC) is the correct resource because it allows a pod to request persistent storage that survives pod restarts. In GKE, a PVC binds to a PersistentVolume (PV), which can be backed by Compute Engine persistent disks, ensuring data remains available even if the pod is rescheduled or restarted.
