An administrator is configuring SSH access on a Cisco router. After setting the hostname and domain name, which command must be used to create the encryption parameters required for SSH?
To enable SSH on a Cisco router, you must generate RSA keys using the crypto key generate rsa command. This command creates the cryptographic keys required for SSH encryption. The hostname and domain name must be configured before generating the keys, as they are used in key generation. The other options do not generate the required encryption keys: ip ssh rsa keys is not a valid command, enable secret password sets the privileged EXEC mode password, and transport input ssh configures the VTY lines to accept SSH connections but does not generate keys.
