Certified Ethical Hacker (CEH v13) — Question 36

A certified ethical hacker is conducting a Whois footprinting activity on a specific domain. The individual is leveraging various tools such as Batch IP Converter and Whois Analyzer Pro to retrieve vital details but is unable to gather complete Whois information from the registrar for a particular set of data. As the hacker, what might be the probable data model being utilized by the domain's registrar for storing and looking up Whois information?

Answer options

• A. Thin Whois model working correctly
• B. Thin Whois model with a malfunctioning server
• C. Thick Whois model with a malfunctioning server
• D. Thick Whois model working correctly

Correct answer: A

Explanation

The correct answer is A, as a Thin Whois model allows registrars to provide minimal information and still function properly. In this case, the hacker is able to retrieve some data, indicating that the model is working correctly. Options B and C suggest server issues, which would prevent any data from being accessed, while D implies the Thick Whois model is functioning correctly, but the hacker is specifically not able to gather complete information.
