George wants to monitor only SFTP traffic in Ethereal. Which filter should he apply?

Explanation:
SFTP traffic is carried by SSH, which uses TCP port 22. To monitor only SFTP, you filter for traffic on port 22 so you see SSH/SFTP packets and exclude others. The other options point to the wrong protocol (Telnet on 23) or a UDP filter (SFTP uses TCP), and one option uses an invalid syntax. Filtering by port 22 isolates SSH/SFTP traffic effectively.
