CV0-004 Deployment Practice Question
This CV0-004 practice question tests your understanding of deployment. 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 cloud engineer needs to deploy a containerized application on Amazon EKS. The application requires a persistent storage volume that can be dynamically provisioned. Which Kubernetes resource should be used to request storage?
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 Kubernetes resource to request storage because it acts as a request for storage by a pod, specifying size, access modes, and optionally a StorageClass. In Amazon EKS, a PVC can trigger dynamic provisioning of an EBS or EFS volume via a StorageClass, decoupling the storage request from the underlying PersistentVolume. This allows the cloud engineer to deploy the containerized application without manually pre-provisioning 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
Cisco often tests the distinction between a PersistentVolume (the actual storage resource) and a PersistentVolumeClaim (the request for storage), leading candidates to mistakenly select PV when the question asks for the resource that 'requests' storage.
Detailed technical explanation
How to think about this question
Under the hood, when a PVC is created in EKS with a StorageClass that uses the EBS CSI driver, the Kubernetes controller manager triggers the external provisioner to call the AWS API (CreateVolume) to dynamically provision an EBS volume. The resulting PV is then bound to the PVC, and the pod mounts the volume via the CSI driver. A real-world scenario is deploying a stateful database like PostgreSQL on EKS, where each pod needs its own dynamically provisioned EBS volume to ensure data persistence across pod restarts.
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.
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 practitioner preparing for the CV0-004 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
