A technician needs to enter a reservation into a router for a customer’s printer to ensure that the printer can be reached consistently. Which of the following does the technician need from the printer?
The technician is creating a DHCP reservation . A DHCP reservation associates a specific IP address with a particular network interface. The network interface is normally identified by its MAC address , also called its physical address or hardware address.
When the printer requests an address from DHCP, the DHCP service recognizes the printer’s MAC address and repeatedly assigns the reserved IP address. This allows computers and print servers to reach the printer consistently without requiring the printer to be manually configured with a static address.
The printer driver version affects how the operating system communicates with the printer, not DHCP addressing.
A spool target relates to print-job processing.
A serial number identifies the physical product but is not normally used by DHCP.
CompTIA objective 2.4 includes DHCP reservations, while objective 2.5 identifies the MAC address as the physical address of a network interface card. Microsoft confirms that DHCP reservations assign an address to a particular client NIC based on its MAC address.
