Exam N10-008 topic 1 question 869 discussion

When a user installs a personal router, it often comes with a built-in DHCP server. This can conflict with the existing DHCP server on the network, causing IP address allocation issues and resulting in network connectivity problems.

C. Rogue DHCP server The user has most likely introduced a rogue DHCP server into the network. Personal routers often come with their own DHCP servers that automatically assign IP addresses to connected devices. If the user’s router is not properly configured or is conflicting with the network’s primary DHCP server, it can cause IP address conflicts and connectivity issues. The other options—broadcast storms, collisions, and DNS poisoning—are less directly related to the introduction of a personal router and switch.
