Certified Ethical Hacker (CEH v12) — Question 158

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 because a Thin Whois model provides basic information directly from the registrar without additional data, which aligns with the inability to gather complete information. Options B and C suggest server issues that would likely prevent any data retrieval, while D implies a Thick Whois model functioning properly, which contradicts the scenario presented.
