A company with strict security requirements uses Vault's Transit secrets engine to encrypt data in a microservices architecture. They have multiple applications that each require a unique encryption key. The security team wants to enforce key rotation every 30 days for all keys, and also require that keys be destroyed after they are no longer used. The application team is concerned that key rotation might cause downtime because applications need to re-encrypt data. The Vault architect needs to design a key management solution. What is the best approach?

Which TWO statements about Vault's Storage Backend are correct?

Drag and drop the steps to configure Vault's PKI secrets engine to issue certificates into the correct order.

A Vault administrator is configuring a new Vault server and wants to ensure that audit logs capture every request and response, including the ability to detect tampering. Which Vault architectural component is responsible for providing this capability?

A Vault operator is troubleshooting a newly deployed Vault server that is initialized but not yet unsealed. The operator needs to understand which component is responsible for holding the unseal keys and root token during the initialization process. Which statement accurately describes the role of the barrier in Vault's architecture?

A Vault administrator is configuring a new Vault server. The server will store secrets in a HashiCorp Consul cluster. The administrator writes a configuration file with the `storage` stanza pointing to Consul and starts Vault. After initialization and unsealing, the administrator notices that Vault is functioning but wants to ensure that the storage backend is highly available. Which statement about Vault's storage backend is accurate?
