   A DevOps team is setting up Vault Enterprise with HSM auto-unseal. They have already initialized the HSM and confirmed it is accessible from the Vault nodes. Which additional configuration step is required before Vault can use the HSM for auto-unsealing?

   • AInstall the HSM client software on every client machine that will access Vault secrets.
   • BGenerate a new master key and store it in the HSM using the Vault CLI before starting the service.
   • CSet the Vault configuration file to specify the HSM library path, the PKCS#11 module, and the partition/slot, then restart Vault.
   • DDisable Shamir unsealing by setting the 'seal' option to 'shamir' in the Vault configuration file.

   A company is required to maintain an audit trail of who unsealed the Vault. They are considering both Shamir and HSM auto-unseal. Which approach provides a clearer audit trail of the individuals involved in the unseal process?

   • ABoth approaches provide the same level of audit detail.
   • BShamir, because each administrator's share entry is logged with their identity.
   • CHSM auto-unseal, because the HSM logs every key usage with a timestamp.
   • DNeither approach provides an audit trail of unseal actions.

   A Vault Enterprise administrator is setting up HSM auto-unseal with a new HSM. The HSM is powered on and connected to the network, but Vault fails to start with an error about the PKCS#11 module. What is the most likely cause of this error?

   • AThe Vault nodes do not have network access to the HSM, so the module cannot be loaded.
   • BThe Vault configuration file does not specify the correct path to the PKCS#11 library.
   • CThe HSM firmware is outdated and does not support the required cryptographic algorithms.
   • DThe HSM is not initialized with a partition, so Vault cannot find a slot.

   A company is moving from Shamir unsealing to HSM auto-unseal. The operations team is concerned about the loss of the 'break-glass' procedure where multiple administrators must come together to unseal. What is a valid way to address this concern while still using HSM auto-unseal?

   • AConfigure the HSM to require a PIN that is split among multiple administrators.
   • BKeep a set of Shamir unseal keys as a backup, stored securely offline, for emergency manual unsealing.
   • CDisable HSM auto-unseal and rely solely on Shamir for all unseal operations.
   • DUse Vault's replication feature to automatically unseal standby nodes in case of a failure.

   In Vault Enterprise, how does auto-unsealing with an HSM work to make the Vault available after a restart?

   • AThe Vault sends the encrypted master key to the HSM, which decrypts it using a key that never leaves the HSM.
   • BVault stores the master key in a file on the HSM's filesystem and reads it during startup.
   • CThe HSM stores the unseal keys in plaintext and automatically applies them to the Vault on startup.
   • DThe HSM generates a new master key each time Vault starts, eliminating the need for any stored key material.
