CompTIA Network+ (N10-008) — Question 350

An IT technician successfully connects to the corporate wireless network at a bank. While performing some tests, the technician observes that the physical address of the DHCP server has changed even though the network connection has not been lost. Which of the following would BEST explain this change?

Answer options

• A. Server upgrade
• B. Duplicate IP address
• C. Scope exhaustion
• D. Rogue server

Correct answer: D

Explanation

The correct answer is D, as a rogue server can appear on the network and provide DHCP services, which may result in a change of the DHCP server's physical address. Options A, B, and C do not adequately explain the sudden change in the DHCP server's MAC address since they pertain to different network issues that wouldn't affect the server's physical address directly.
