CompTIA Linux+ (XK0-005) — Question 88

A systems administrator is tasked with setting up key-based SSH authentication. In which of the following locations should the administrator place the public keys for the server?

Answer options

• A. ~/.sshd/authkeys
• B. ~/.ssh/keys
• C. ~/.ssh/authorized_keys
• D. ~/.ssh/keyauth

Correct answer: C

Explanation

The correct answer is C, as the public keys must be placed in the ~/.ssh/authorized_keys file for SSH to recognize and authenticate them. The other options are incorrect because they refer to non-standard directories or filenames that do not serve the purpose of storing authorized keys for SSH access.
