D. ssh-copy-id F. scp The ssh-copy-id and scp commands can be used to copy an SSH key file to remote servers. The ssh-copy-id command is used to install the public key of an SSH key pair to the authorized_keys file of a remote server. This allows the user to log into the remote server without a password, using the private key of the key pair.

For example: ssh-copy-id user@remote_server The scp command is used to securely copy files between systems over an SSH connection. The command can be used to copy an SSH key file to a remote server. For example: scp ~/.ssh/id_rsa.pub user@remote_server:/tmp/id_rsa.pub

In this example, the public key of the SSH key pair (~/.ssh/id_rsa.pub) is copied to the remote server (remote_server) in the /tmp directory with the name id_rsa.pub. The administrator can then use the ssh-copy-id command to install the public key on the remote server.
