CompTIA Network+ (N10-008) — Question 871

A user is experiencing network connectivity issues. Upon investigation, the engineer learns that the user installed a personal router and switch to use for multiple computers in the department. Which of the following has the user most likely introduced into the network?

Answer options

• A. Broadcast storms
• B. Collisions
• C. Rogue DHCP server
• D. DNS poisoning

Correct answer: C

Explanation

The correct answer is C, as the introduction of a personal router can lead to the creation of a rogue DHCP server, causing IP address conflicts and connectivity issues. Options A and B refer to different types of network issues that are less likely to stem from the addition of a personal router, while D pertains to a different threat vector that does not directly relate to the user's setup.
