What is the purpose of a PersistentVolumeClaim in Kubernetes?

• A. To request and bind storage resources for a Pod
• B. To define a network policy
• C. To specify container image
• D. To configure memory limits

Answer: (A)

A PersistentVolumeClaim is a request for storage resources that a pod can use. It lets you specify how much storage you need, the access mode (how the volume can be mounted by the pod), and optionally a storage class for provisioning. Kubernetes then binds this claim to a matching PersistentVolume (or dynamically provisions one via a StorageClass) and the pod can mount that storage by referencing the claim. This decouples the storage lifecycle from the pod lifecycle, enabling flexible, on-demand storage for workloads. The other choices describe network policy, container image, and memory limits, which are unrelated to reserving or binding storage resources.
