VA-003 Compare and configure secrets engines Practice Question
An admin needs to store a configuration value that is unique to each Vault client and must not be shared. Which secrets engine should they use?
⚠ Common exam trap
HashiCorp often tests the misconception that KV v2 with strict ACLs provides the same isolation as Cubbyhole, but the trap is that KV v2 is path-based and policy-dependent, whereas Cubbyhole is inherently token-scoped and cannot be accessed by any other token, even with root privileges.

Correct answer & explanation
✓
Cubbyhole
The Cubbyhole secrets engine creates a private, ephemeral storage space that is scoped to the requesting token. Each token gets its own isolated cubbyhole, and no other client or token can read or write to it, even with root privileges. This makes it the only built-in engine that guarantees a configuration value is unique to each Vault client and cannot be shared.
