A. B. C. D.D.
https://www.linode.com/docs/security/securing-your-server/The file that should contain the public key to gain remote access to a Linux server using SSH is the ~/.ssh/authorized_keys file. This file is located in the user's home directory, and it contains a list of public keys that are authorized to access the server using SSH.
Here's a more detailed explanation of each of the options:
A. ~/ssh/authorized-keys: This is not a valid path for an authorized keys file. The correct directory is ~/.ssh/.
B. /etc/authorized_keys: This is also not a valid path for an authorized keys file. The correct path is ~/.ssh/authorized_keys, which is located in the user's home directory.
C. /etc/sshd/ssh.conf: This file does not contain authorized keys. Instead, it is the main configuration file for the SSH server, and it contains settings for the server's behavior and security.
D. ~/.ssh/authorized_keys: This is the correct file and location for authorized keys. The ~ symbol represents the user's home directory, and the . before ssh indicates that it is a hidden directory. The authorized_keys file should contain a list of public keys, one per line, that are authorized to access the server using SSH.
Therefore, the correct answer is D. ~/.ssh/authorized_keys.
