A new network engineer is configuring a DHCP server for a branch office network. They need to ensure that the branch office printer (MAC 00:1A:2B:3C:4D:5E) always receives the IP address 192.168.50.100, while all other devices receive dynamic addresses from the 192.168.50.0/24 scope.
What DHCP feature accomplishes this, and how does it differ from configuring a static IP directly on the printer?
- A.Configure the printer's IP as an excluded address in the DHCP scope; the printer then auto-assigns itself 192.168.50.100; a DHCP relay agent converts unicast discovers into broadcasts so remote servers can hear them. Hosts renew leases by contacting any DHCP server, not the one that issued the lease, as the protocol keeps no server identity. A DHCPOFFER is unicast to 255.255.255.255 with the client's new lease inside the DNS payload
- B.Configure the printer with a static IP directly on the device; DHCP reservations do not work for printers
- C.Create a DHCP reservation (static DHCP binding) linking the printer's MAC address 00:1A:2B:3C:4D:5E to IP 192.168.50.100; the DHCP server always assigns this IP to that MAC address. Advantage over static: DNS options, gateway, and other DHCP options are centrally managed; the printer still uses DHCP protocol to get its configuration, making it easier to change options centrally without touching the printer
