Which statement about ephemeral storage in Kubernetes is true?

• A. A persistent volume bound to a node.
• B. A temporary storage type tied to the Pod lifecycle.
• C. An external network drive.
• D. A block device attached to the cluster's master.

Answer: (B)

Ephemeral storage is storage that exists only for the lifetime of a Pod and lives on the node’s local disk (for example, an emptyDir volume). It’s intended for scratch space, caches, or other data you don’t need to persist beyond the Pod’s life. When the Pod is deleted or rescheduled, this data is removed, unlike persistent volumes which are designed to outlive a Pod and can be reattached to other Pods or moved across nodes. You can also set requests and limits for ephemeral storage to influence scheduling and eviction during disk pressure. This makes the statement describing ephemeral storage as temporary storage tied to the Pod lifecycle the correct one.
