A developer mistakenly committed code that contained AWS S3 credentials into a public repository.

The correct answer is A because the lease ID is the unique identifier for the credential. Thelease ID is used to revoke the credential using the vault lease revoke command. This command will invalidate the credential immediately and prevent any further renewals. It will also delete the access key and secret key from AWS, rendering them useless1. The access key and secret key are not sufficient to revoke the credential, as they are not recognized by Vault. The lease ID is composed of the path of the secrets engine, the role name, and a random UUID. In this case, the path is aws/creds, the role name is s3-access, and the UUID is f3e92392-7d9c-99c8-c921-57Sd62fe89d8.
