Linux Foundation Certified System Administrator (LFCS) — Question 116

Which of the following commands connects to the remote host example.com which has OpenSSH listening on TCP port 2222? (Choose TWO correct answers.)

Answer options

• A. ssh --port 2222 example.com
• B. ssh -p 2222 example.com
• C. ssh -o Port=2222 example.com
• D. ssh -o GatewayPort=2222 example.com
• E. ssh example.com:2222

Correct answer: B, C

Explanation

The correct answers are B and C because both commands specify the port for the SSH connection correctly using the '-p' option and the '-o Port=' option respectively. Option A is incorrect due to the use of '--port', which is not a recognized option in SSH, while D and E do not correctly set the port for the SSH connection.
