CompTIA Linux+ (XK0-005) — Question 246

A systems administrator creates a public key for authentication. Which of the following tools is MOST suitable to use when uploading the key to the remote servers?

Answer options

• A. scp
• B. ssh-copy-id
• C. ssh-agent
• D. ssh-keyscan

Correct answer: B

Explanation

The correct answer, ssh-copy-id, is specifically designed for installing SSH keys on remote servers, making it the most suitable option. While scp can transfer files, it is not tailored for key installation. ssh-agent is used for managing private keys, and ssh-keyscan is for gathering SSH public keys from remote hosts, neither of which fulfills the key uploading function.
