Certified Ethical Hacker (CEH) — Question 78

Which of the following is an application that requires a host application for replication?

Answer options

• A. Micro
• B. Worm
• C. Trojan
• D. Virus

Correct answer: D

Explanation

The correct answer is D, Virus, because a virus attaches itself to a host application to replicate and spread. In contrast, a worm can replicate independently over networks, a Trojan disguises itself but does not replicate, and Micro is not a recognized malware type related to replication.
