Which storage type in Kubernetes is typically allocated for short-lived data that doesn't survive pod restarts?

• A. Persistent Volume
• B. Network File System
• C. Ephemeral storage
• D. Persistent Volume Claim

Answer: (C)

Ephemeral storage is the storage tied to a Pod’s lifetime on the node. It provides scratch space for temporary files, caches, and other data that can be recreated or discarded if the Pod restarts. Because it lives on the node and isn’t backed by a persistent volume, the data is not guaranteed to survive pod restarts, making it the typical choice for short-lived data. In contrast, persistent volumes and persistent volume claims are designed to persist beyond Pod lifecycles, and a network file system can also provide durable storage depending on configuration. So ephemeral storage is the best fit for data that should not survive restarts.
