- A
StatefulSet with volumeClaimTemplates for persistent storage
Why wrong: StatefulSets are intended for stateful applications that require stable network identities and persistent storage, not for stateless microservices that need rolling updates and zone spreading.
- B
Deployment with pod anti-affinity rules spread across zones
Deployments provide rolling updates and replica management; combined with pod anti-affinity, they can ensure pods are distributed across zones for high availability.
- C
Job for batch processing
Why wrong: Jobs are for running a finite task to completion, not for long-running services that need to be always available and scaled.
- D
DaemonSet to ensure one pod per node
Why wrong: DaemonSets run a pod on every node, which is not suitable for services that should be scaled and spread across zones; they are used for node-level functions like logging or monitoring.
Google PCA Deployment Practice Question
This PCA practice question tests your understanding of design and plan a cloud solution architecture. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. A key principle to apply: deployment. 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 is designing a microservices architecture on Google Kubernetes Engine (GKE) for a global user base. They require high availability across multiple zones, automatic scaling, and rolling updates without downtime. Which Kubernetes workload resource should they use for each service?
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
Deployment with pod anti-affinity rules spread across zones
Option B is correct because Deployments support rolling updates for zero-downtime deployments, and pod anti-affinity rules can be configured to spread pods across different zones, ensuring high availability. StatefulSets are intended for stateful workloads requiring stable network identities and persistent storage, not for stateless microservices. DaemonSets run one pod per node, typically for node-level services like logging, not for scaling microservices. Jobs are for batch processing and do not provide rolling updates or high availability across zones.

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
Treat this as a scenario question. Identify the problem, the constraint, and the best action. Then compare each option against those facts.

- Rolling Update
TExam Day Tips
- 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
Deployment
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.
