What best describes Ephemeral Storage in Kubernetes?

• A. A persistent storage type linked to a node.
• B. A temporary storage type that is tied to the lifecycle of a Pod.
• C. A network-tied storage for cross-pod sharing.
• D. A storage class that enables dynamic provisioning.

Answer: (B)

Ephemeral storage is storage that exists on the node for the lifetime of a Pod and disappears when the Pod is deleted. It’s used for temporary data like scratch space, caches, and logs, and it won’t survive Pod restarts or rescheduling. This kind of storage is typically backed by volumes like emptyDir, which are created when the Pod starts and removed when the Pod ends. You can also declare ephemeral-storage resources in a Pod so the scheduler and kubelet can handle disk pressure and eviction if needed. It’s not meant for long-term persistence, not shared across pods, and not provided by a StorageClass for dynamic provisioning.
