Google ACE Deploying and implementing a cloud solution Practice Question
This ACE practice question tests your understanding of deploying and implementing a cloud solution. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 is deploying a stateful application on Google Kubernetes Engine (GKE) that requires persistent storage. Each pod needs its own dedicated persistent disk that is not shared. Which Kubernetes resource should be used to manage the deployment?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
StatefulSet with volumeClaimTemplates
Option D is correct because a StatefulSet with volumeClaimTemplates is designed for stateful applications where each pod requires its own dedicated PersistentVolume (PV) that is not shared. The volumeClaimTemplates automatically generate a unique PersistentVolumeClaim (PVC) for each pod replica, ensuring each pod gets a separate, stable persistent disk that persists across rescheduling. This matches the requirement for a stateful application on GKE where pods need dedicated, non-shared storage.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Job with PersistentVolume
Why it's wrong here
Jobs are for batch tasks and not suitable for long-running stateful services.
✗
DaemonSet with hostPath volumes
Why it's wrong here
DaemonSet runs a pod on each node, but hostPath does not provide dedicated disks per pod and is not recommended for production.
✗
Deployment with PersistentVolumeClaim template
Why it's wrong here
Deployments treat pods as interchangeable and do not maintain stable persistent volume claims per pod.
✓
StatefulSet with volumeClaimTemplates
Why this is correct
StatefulSet creates unique PersistentVolumeClaims for each pod, ensuring dedicated persistent storage.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Google Cloud often tests the distinction between Deployments and StatefulSets, and the trap here is that candidates mistakenly choose a Deployment with a PVC template, not realizing that Deployments treat all pods as interchangeable and would share the same PVC, violating the 'dedicated disk per pod' requirement.
Detailed technical explanation
How to think about this question
Under the hood, StatefulSet uses a headless service (with clusterIP: None) to provide stable network identities, and volumeClaimTemplates create PVCs with a naming convention like <volumeClaimTemplate-name>-<statefulset-name>-<ordinal>, ensuring each pod gets a unique PV. In GKE, this leverages Compute Engine persistent disks, which are zonal resources; if a pod is rescheduled to a different zone, the PV will not be available, so StatefulSets often require regional persistent disks or topology-aware scheduling to maintain availability. A real-world scenario is deploying a Cassandra or MySQL cluster where each node needs its own data volume and stable hostname.

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
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.
