312-50V13 Question #417: Real Exam Question with Answer & Explanation

Question

Which type of malware spreads from one system to another or from one network to another and causes similar types of damage as viruses do to the infected system?

Options

• ARootkit
• BTrojan
• CWorm
• DAdware

Explanation

A worm is a type of malware that self-replicates and spreads independently across networks, causing damage similar to a virus but without requiring user interaction for propagation.

Common mistakes.

• A. A rootkit allows an attacker to maintain hidden access to a system but does not primarily describe a method of self-replication or widespread damage across systems.
• B. A Trojan disguises itself as legitimate software to trick users but typically does not self-replicate and spread to other systems.
• D. Adware displays unwanted advertisements and is not primarily designed to self-replicate and spread across systems to cause damage.
