During a reconnaissance phase, a penetration tester is using a tool to enumerate NetBIOS names on a target internal network. The tester issues the command 'nbtstat -A 192.168.1.100' on a Windows machine. What type of information is the tester most likely trying to obtain?

Answer choices

Why each option matters

Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.

A

Distractor review

The operating system version and patch level

Operating system details are not part of NetBIOS name table output. Tools like nmap with OS detection are used for that.

B

Distractor review

A list of currently open TCP ports on the remote system

nbtstat does not scan ports; it queries NetBIOS over TCP/IP services (port 139/445) for name information.

C

Distractor review

The MAC address of the remote network interface

While NetBIOS name table may include a MAC address in some cases, the primary goal is to obtain names, not the MAC.

D

Best answer

The NetBIOS name table including computer name, logged-in users, and domain

nbtstat -A retrieves the NetBIOS name table, which contains names associated with the system, useful for identifying roles and users.

Common exam trap

Common exam trap: NAT rules depend on direction and matching traffic

NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.

Technical deep dive

How to think about this question

NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.

KKey Concepts to Remember

  • Static NAT maps one inside address to one outside address.
  • PAT allows many inside hosts to share one public address using ports.
  • Inside local and inside global describe the private and translated addresses.
  • NAT ACLs identify traffic for translation, not always security filtering.

TExam Day Tips

  • Identify inside and outside interfaces first.
  • Check whether the scenario needs static NAT, dynamic NAT or PAT.
  • Do not confuse NAT matching ACLs with normal packet-filtering intent.

FAQ

Questions learners often ask

What does this PT0-002 question test?

Static NAT maps one inside address to one outside address.

What is the correct answer to this question?

The correct answer is: The NetBIOS name table including computer name, logged-in users, and domain — The 'nbtstat -A' command displays the NetBIOS name table of the remote computer, including the computer name, domain/workgroup name, and logged-in users. This information can help identify the role of the machine or find active usernames for further attacks. It does not provide detailed system information like OS version or patch level (that would be done with nmap OS detection or other tools). It also does not show open TCP ports (that requires port scanning). And it does not directly provide the MAC address (though some output may include adapter addresses, the primary purpose is NetBIOS names).
