You receive several calls from a group of users about a lack of network connectivity. After investigating, you find all the users are on a brand-new segment off the internal router. Your network uses DHCP and all users on the original segment are functioning fine. What is the most likely cause of the problem?

A. Every user on the new segment has manually assigned their own TCP/IP address information.

B. The DHCP server is on the original segment, and DHCP requests are not allowed to cross a router.

C. Cabling to a single host on the new segment has been severed, taking down the entire network.

D. This is a temporary problem. Simply waiting longer will fix it.

Solution

B is correct. DHCP messages are sent broadcast and therefore will not cross the router.

A, C, and D are incorrect. A is incorrect because it is unlikely every client manually changed their TCP/IP configuration at the same time. C is incorrect because cabling to a single host would not bring the entire network segment down. D is incorrect because waiting will not fix this problem.
