CompTIA Network+ (N10-007) — Question 210

A network technician receives a call from a user who is experiencing network connectivity issues. The network technician questions the user and learns the user brought in a personal wired router to use multiple computers and connect to the network. Which of the following has the user MOST likely introduced to the network?

Answer options

• A. Rogue DHCP server
• B. Evil twin
• C. VLAN mismatch
• D. Honeypot

Correct answer: A

Explanation

The user most likely set up a personal wired router that can act as a rogue DHCP server, providing IP addresses that conflict with the main network's DHCP server. This can lead to connectivity issues for other devices on the network. The other options, such as Evil twin, VLAN mismatch, and Honeypot, do not directly relate to the scenario of a personal router causing DHCP conflicts.
