- A
A separate database such as Cloud SQL
Why wrong: Incorrect. Velero does not require Cloud SQL; it uses object storage for backups.
- B
A Velero plugin for each persistent volume
Why wrong: Incorrect. Velero backs up cluster resources and volumes, not etcd itself.
- C
A dedicated backup server with stateful storage
Why wrong: Incorrect. kubeconfig is a client configuration, not a required component for Velero's backend.
- D
A Cloud Storage bucket for backup storage
Correct. A Cloud Storage bucket is needed to store backup data.
- E
Access to the cluster's kubeconfig file
Access to the cluster's kubeconfig file is required so that Velero can authenticate to the Kubernetes API server and perform backups of cluster resources and persistent volumes.

Google PCA Practice Question: Managing Implementation and Ensuring Solution and Operations Reliability
This PCA practice question tests your understanding of managing implementation and ensuring solution and operations reliability. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company wants to back up their GKE cluster's etcd data and persistent volumes for disaster recovery. They are evaluating Velero. Which two components does Velero require to perform backups? (Choose two.)
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
✓
A Cloud Storage bucket for backup storage
Velero requires two core components: a storage destination (like a Cloud Storage bucket) to store backup artifacts, and access to the Kubernetes API server, typically through a kubeconfig file, to orchestrate backups. The kubeconfig file allows Velero to authenticate and interact with the cluster's API server to collect resource definitions and trigger volume snapshots. Without it, Velero cannot access cluster resources. A storage bucket is needed for durable backup storage.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
