Difficulty: EasyIP Addressing and Network Configuration

A system administrator needs to configure a network printer so that it automatically receives the exact same IPv4 address every time it boots up, without manually configuring a static IP address on the printer itself. Which of the following should the administrator configure on the network server?

  1. A DHCP reservation linked to the printer's MAC addressAnswer
  2. B
    A DNS A record mapping the printer's host name to an IP address
  3. C
    An APIPA address block assignment on the network interface
  4. D
    A default gateway IP address on the local router interface

Answer

A DHCP reservation linked to the printer's MAC address
Configuring a DHCP reservation on the server binds the printer's unique MAC address to a specific IPv4 address. Every time the printer requests dynamic configuration upon startup, the DHCP server matches the MAC address and leases the exact designated IP address.

Step-by-Step Solution

1
Identify the configuration requirement
The printer requires a permanent, predictable IP address assigned automatically via the network rather than set manually on the physical device.
Centralized IP management reduces manual administrative effort and prevents configuration conflicts.
2
Evaluate network server roles
DHCP is responsible for leasing IP addresses. A DHCP reservation binds the hardware MAC address of the printer to a specific static IP address pool entry.
When the printer broadcasts a DHCP Request, the DHCP server recognizes its MAC address and always assigns the reserved IP address.
