CompTIA Linux+ (XK0-004) — Question 5

A Linux systems administrator wants the ability to access systems remotely over SSH using RSA authentication. To which of the following files should the RSA token be added to allow this access?

Answer options

• A. authorized_keys
• B. ~/.ssh/ssh_config
• C. id_rsa.pub
• D. known_hosts

Correct answer: A

Explanation

The correct answer is A, 'authorized_keys', because this file stores the public keys that are allowed to authenticate to the SSH server. Options B, C, and D are incorrect as they serve different purposes: B is for client-side configuration, C is the public key file itself, and D is for known hosts verification.
