Certified Ethical Hacker (CEH v13) — Question 268

Which file is a rich target to discover the structure of a website during web-server footprinting?

Answer options

• A. domain.txt
• B. Robots.txt
• C. Document root
• D. index.html

Correct answer: B

Explanation

The correct answer is Robots.txt because it contains directives for web crawlers about which parts of the site should not be accessed, often revealing the site's structure and sensitive areas. The other options, such as domain.txt, Document root, and index.html, do not provide the same level of insight into the site's navigation and restrictions placed on it.
