A network administrator needs to ensure a critical server consistently receives the same IP address from the DHCP server to avoid connectivity disruptions. Which of the following methods is the BEST solution to meet this requirement?
Conduct a capacity test on the DHCP server's address assignment capabilities.
Manually set a static IP address on the server from within the DHCP server's assignable address pool.
Adjust the DHCP server's pool of available addresses to create an exclusion range.
Create a DHCP reservation for the server's MAC address on the DHCP server.
Creating a DHCP reservation for the server's MAC address on the DHCP server is the best solution. A reservation ensures the DHCP server will always assign the same specific IP address to that server's MAC address. This method maintains consistent network access for the server, even after a reboot or lease expiration. Manually setting a static IP address on the server from within the DHCP server's assignable address pool could cause an IP address conflict. Adjusting the address pool (creating an exclusion) only prevents the DHCP server from assigning addresses from the excluded range; it does not assign a specific address to the server. A capacity test is irrelevant as it measures server performance, not specific address assignment.
