True or False?

Comprehensive and Detailed in Depth Explanation:

The statement isTrue. The vault lease revoke -prefix aws/ command revokes all leases under the specified prefix. The HashiCorp Vault documentation states: "The vault lease revoke command is used to revoke leases. Using the -prefix flag allows you to revoke entire trees of secrets." When applied to aws/, it targets all leases associated with the secrets engine mounted at that path.

The docs further explain under "Prefix-Based Revocation": "The -prefix option allows revocation of all leases that share a common prefix, effectively cleaning up all secrets under a mount point or path." Thus, A (True) is correct.
