Google PCA Practice Question: Managing Implementation and Ensuring Solution and Operations Reliability
Your company runs a stateful application on GKE that stores data in persistent volumes backed by Compute Engine persistent disks. You need to back up the application data and the Kubernetes resource configurations (deployments, services, etc.) for disaster recovery. Which tool should you use?
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
✓
Velero
Velero (formerly Heptio Ark) is an open-source tool for backing up and restoring Kubernetes cluster resources and persistent volumes. It supports GCP as a storage destination (Cloud Storage). Cloud Storage versioning can back up files but not Kubernetes resources. gcloud container clusters create does not back up. Cloud SQL is for relational databases.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Velero
Why this is correct
Velero backs up Kubernetes resources and persistent volumes to Cloud Storage.
- ✗
gcloud container clusters create --async
Why it's wrong here
This command creates a new cluster, not a backup of existing resources.
- ✗
Cloud SQL for MySQL
Why it's wrong here
Cloud SQL is a database service, not for backing up arbitrary Kubernetes resources.
- ✗
Cloud Storage with object versioning and lifecycle policies
Why it's wrong here
Object versioning stores object versions but does not capture Kubernetes resource state.
