A stateful inspection app needs data that outlives pod rescheduling onto another node. Which storage choice best fits?
Select an answer to reveal the explanation.
Short Explanation
Stateful apps need luggage that follows them when the pod changes hotels. A persistent volume is that luggage. The container's scratch layer is a hotel notepad—gone at checkout.
Full Explanation
Persistent volumes provide durable storage that can outlive individual pods and support rescheduling onto other nodes when the platform allows reattachment. Ephemeral writable layers and tmpfs lose state on restart or move. Stateful inspection workloads generally require persistent volume abstractions rather than disposable local layers.
