Certified Ethical Hacker (CEH v13) — Question 80

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 using a tool that supports IPv6 is essential for effective enumeration in an IPv6 environment. Option B is incorrect as nbtstat does not natively support IPv6 addresses directly in that format. Option C won't provide the needed enumeration for the target since it only shows cached names. Option D, while useful, does not specifically cater to the immediate need to switch to an IPv6-compatible tool.
