CompTIA Network+ (N10-009) — Question 467

Which of the following is an attack that provides a malicious default gateway IP over a wired network?

Answer options

• A. Evil twin
• B. DNS spoofing
• C. ARP poisoning
• D. Rogue DHCP server

Correct answer: D

Explanation

The correct answer is D, Rogue DHCP server, as it can assign a malicious default gateway IP to clients on the network. Option A, Evil twin, refers to a Wi-Fi attack where a malicious access point mimics a legitimate one, but does not specifically deal with default gateways. Option B, DNS spoofing, involves manipulating DNS responses and does not provide a gateway IP, while C, ARP poisoning, involves misleading devices about IP-to-MAC address mappings but does not directly assign a gateway.
