Kubernetes and Cloud Native Associate (KCNA) — Question 114

What is ephemeral storage?

Answer options

• A. Storage space that need not persist across restarts.
• B. Storage that may grow dynamically.
• C. Storage used by multiple consumers (e.g. multiple Pods).
• D. Storage that is always provisioned locally

Correct answer: A

Explanation

The correct answer, A, describes ephemeral storage as temporary storage that does not need to retain data after a restart, which is its defining characteristic. Option B refers to dynamic storage, which is not specific to ephemeral storage. Option C describes shared storage, which doesn't capture the transient nature of ephemeral storage. Option D inaccurately suggests that ephemeral storage is always local, which is not necessarily true.
