CompTIA Network+ (N10-006) — Question 21

Ann, an employee, has properly connected her personal wireless router to a network jack in her office. The router is unable to get a DHCP address though her corporate laptop can get a DHCP address when connected to the same jack. Ann checks the router configuration to ensure it is configured to obtain a DCHP address.
Which of the following is the MOST likely reason why the router is not receiving a DHCP address?

Answer options

• A. The administrator has enabled DHCP snooping on the network
• B. The administrator is blocking DHCP requests that originate from access points
• C. The administrator is blocking the wireless router's MAC address using MAC filtering
• D. The Administrator has implemented a feature that only allows white-listed MAC addresses

Correct answer: D

Explanation

The correct answer is D because the administrator's policy likely restricts devices to only those with approved MAC addresses, preventing Ann's router from obtaining a DHCP address. Options A and B refer to blocking DHCP requests, which would affect all devices, and option C points specifically to MAC filtering, but since the correct answer is focused on a whitelist policy, it is the most accurate explanation.
