GIAC Certified Incident Handler (GCIH) — Question 76

Which of the following netcat commands will connect to tcp port 2222 on a remote system (10.0.0.1)?

Answer options

• A. C:\>nc.exe 10.0.0.1 2222
• B. C:\>nc.exe 10.0.0.1 -l -p 2222
• C. C:\>nc.exe 10.0.0.1 -L 2222
• D. C:\>nc.exe 10.0.0.1 -p 2222

Correct answer: B

Explanation

The correct answer is B, as the command includes the '-l' option which specifies that netcat should listen for incoming connections on the specified port. Options A, C, and D do not have the correct syntax for establishing a listening connection, making them unsuitable for the desired action.
