CompTIA Server+ (SK0-005) — Question 220

An administrator is troubleshooting a failed NIC in an application server. The server uses DHCP to get all IP configurations, and the server must use a specific IP address. The administrator replaces the NIC, but then the server begins to receive a different and incorrect IP address. Which of the following will enable the server to get the proper IP address?

Answer options

• A. Modifying the MAC used on the DHCP reservation
• B. Updating the local hosts file with the correct IP address
• C. Modifying the WWNN used on the DHCP reservation
• D. Updating the NIC to use the correct WWNN

Correct answer: A

Explanation

The correct answer is A because DHCP reservations are tied to MAC addresses, and modifying the MAC in the reservation will allow the server to get the correct IP. Options B and C do not affect DHCP assignments, and D is irrelevant since WWNN is not typically used for standard DHCP configurations.
