You have manually created some usernames and passwords for a Microsoft SQL database on Azure, and need to store these credentials in Vault. What secrets engine should you use for this?

The MSSQL database secrets engine is used for dynamically generating database credentials, not for storing existing static ones.

The Key/Value (KV) secrets engine, particularly version 2, is designed for storing arbitrary static secrets like manually created usernames and passwords, offering versioning and auditing capabilities.

The Azure secrets engine is used for dynamically generating Azure-specific credentials, not for storing general database credentials.

The Transit engine is used for cryptographic functions like encryption as a service, not for storing secrets directly.
