200-301: Cisco Certified Network AssociateDemo

On Cisco IOS, SSH server access using RSA requires the device to have its identifying settings configured first, including the domain name, and then an RSA key pair must be created. The command that creates that key pair is crypto key generate rsa. crypto key zeroize rsa removes existing RSA keys, crypto key pubkey-chain rsa is used to manage public keys, and crypto key import rsa pem is for importing keys rather than performing the normal next step in basic SSH setup.
