CompTIA Network+ (N10-009) — Question 127

Which of the following attacks would most likely cause duplicate IP addresses in a network?

Answer options

• A. Rogue DHCP server
• B. DNS poisoning
• C. Social engineering
• D. Denial-of-service

Correct answer: A

Explanation

A Rogue DHCP server can distribute IP addresses that conflict with those already assigned by the legitimate DHCP server, leading to duplicate IP addresses on the network. The other options, such as DNS poisoning, social engineering, and denial-of-service, do not inherently cause IP address duplication.
