Certified Ethical Hacker (CEH v12) — Question 145

You are an ethical hacker tasked with conducting an enumeration of a company's network. Given a Windows Answered Marked for Review 37.6% system with NetBIOS enabled, port 139 open, and file and printer sharing active, you are about to run some nbtstat commands to enumerate NetBIOS names. The company uses IPv6 for its network. Which of the following actions should you take next?

Answer options

• A. Switch to an enumeration tool that supports IPv6
• B. Use nbtstat -a followed by the IPv6 address of the target machine
• C. Use nbtstat -c to get the contents of the NetBIOS name cache
• D. Utilize Nmap Scripting Engine (NSE) for NetBIOS enumeration

Correct answer: A

Explanation

The correct answer is A because you need an enumeration tool that supports IPv6 to properly interact with the network. While B suggests using an IPv6 address with nbtstat, the command doesn't support IPv6 directly. Option C is not relevant since it only retrieves cached names, and D, while useful for enumeration, does not directly address the need for IPv6 compatibility.
