Certified Ethical Hacker (CEH v13) — Question 75

Being a Certified Ethical Hacker (CEH), a company has brought you on board to evaluate the safety measures in place for their network system. The company uses a network time protocol server in the demilitarized zone. During your enumeration, you decide to run a ntptrace command. Given the syntax: ntptrace [-n] [-m maxhosts] [servername/IP_address], which command usage would best serve your objective to find where the NTP server obtains the time from and to trace the list of NTP servers connected to the network?

Answer options

• A. ntptrace -n -m 5192.168.1.1
• B. ntptrace -m 5192.168.1.1
• C. ntptrace -n localhost
• D. ntptrace 192.168.1.1

Correct answer: D

Explanation

The correct answer is D because it directly specifies the IP address of the NTP server, allowing you to trace its time source and connected servers. Option A incorrectly uses the '-m' flag with an invalid IP format, while option B also misuses the '-m' flag without the necessary '-n' flag. Option C points to 'localhost', which would not provide information about external NTP servers.
