Exam 202-450 topic 1 question 11 discussion

the answer should be C ~/.ssh/id_rsa.pub

I agree with Ianc. The answer should be C. The authorized_keys contains the list of public keys that are authorized to access. The "id_rsa.pub" contains the public key of the client and it's append in the remote server into the authorized_keys file.

Correct answer C: Copy the id_rsa.pub file to the remote server. The key contents must be copied into the ∼/.ssh/authorized_keys file for your user account on the remote server. You can do that using the cat command: $ cat id_rsa.pub >> ∼/.ssh/authorized_keys

Correct answer is C.

The correct answer is C ssh-copy-id username@remote_host The utility will connect to the account on the remote host using the password you provided. It will then copy the contents of your ~/.ssh/id_rsa.pub key into a file in the remote account’s home ~/.ssh directory called authorized_keys. https://www.digitalocean.com/community/tutorials/how-to-configure-ssh-key-based-authentication-on-a-linux-server

C is the right one

To log into a remote SSH server using SSH keys, you need to transmit the content of your public key to the remote server. The public key is usually stored in a file named ~/.ssh/id_rsa.pub (option C). So, the correct answer is: C. ~/.ssh/id_rsa.pub This public key file needs to be added to the ~/.ssh/authorized_keys file on the remote server to grant you access using SSH keys.

The question is referring to the CONTENT of the file that is LOCAL ON THE SERVER. So, the client needs to trasmit data that match the content of authorized_keys on the server. The question is really ambigous though.

C is the answer . The question is referring to the file you need to copy in a server for authenticate by ssh-key pair handshake.

I think its C

C 100%

~/.ssh/id_rsa.pub is the file to be copy. The question ask about the CONTENT of local file. If you copy the authorized_keys, you are able to use a remote server, because the authorized_keys has the pub key. Then, the correct answer is A

Read the question as _which file should be copied?_ and think _source and destion file_ remain the same.

The answer should be C.

The question is regarding a LOCAL file that should be placed on remote server. ~/.ssh/id_rsa.pub is the LOCAL file that will "become" a authorized_keys on the remote

I think that "A" "~/.ssh/authorised_keys" is a file used on the SSH server side to store the SSH public key of a trusted user. This is the correct answer. "~/.ssh/config" is the file used by the SSH client to configure SSH. "~/.ssh/id_rsa.pub" is the file containing the user's SSH public key. "~/.ssh/id_rsa" is the file containing the user's SSH private key. "~. /ssh/known_hosts" is the file that stores the public key of the trusted SSH server (the public key of the SSH server itself is stored in "/etc/ssh/ssh_host_TYPE_key.pub", where "TYPE" is the encryption method).

authorized_keys = public keys that are authorized to access. id_rsa.pub contains = public key of the client that should be added into the authorized_keys file of remote server.
