Which tool helps security professionals check for both LLMNR and NBNS spoofing?

• A. got-responded
• B. Vindicate
• C. Respounder
• D. SecurityFocus

Answer: (A)

LLMNR and NBNS spoofing checks rely on a tool that can monitor and respond to local name resolution traffic in order to reveal impersonation attempts. got-responded is designed for this purpose: it engages with LLMNR and NBNS traffic to detect when another host is spoofing those services, helping security professionals identify vulnerable machines or misconfigurations and verify whether defenses against these attacks are effective. By using such a tool, you can observe if clients are credibly lured into authenticating to a rogue responder, which is the telltale sign of spoofing in these protocols. In practice, this kind of tool acts as a controlled tester in the network, capturing and analyzing responses to local name resolution requests and highlighting anomalies that indicate spoofing activity. This makes it the best fit among the options for proactively checking both LLMNR and NBNS spoofing in a real environment. The other choices don’t fit as a combined LLMNR/NBNS spoofing checker: one is not a recognized tool for this purpose, another isn’t a known utility for spoofing detection, and SecurityFocus is a vulnerability information resource rather than a tool for testing spoofing.
