LPIC-2 Exam 202 (Linux Engineer) — Question 48

Which of the following nmap parameters scans a target for open TCP ports? (Choose two.)

Answer options

• A. -sO
• B. -sZ
• C. -sT
• D. -sU
• E. -sS

Correct answer: C, E

Explanation

The correct options, -sT and -sS, are used to perform TCP scans; -sT is a connect scan and -sS is a stealth SYN scan. The other options, -sO (IP protocol scan), -sZ (TCP ACK scan), and -sU (UDP scan), do not apply to scanning for open TCP ports.
