What is the purpose of DHCP reservations?

• A. To assign dynamic addresses randomly
• B. To ensure specific devices receive the same IP address
• C. To configure network devices for static IP
• D. To improve broadcast domain efficiency

Answer: (B)

The purpose of DHCP reservations is to ensure that specific devices receive the same IP address each time they connect to the network. When a DHCP server is configured to reserve an IP address for a particular device, it associates the device's MAC (Media Access Control) address with that designated IP address. This way, whenever the device requests an IP address through DHCP, the server recognizes it and assigns the reserved IP, maintaining consistency in addressing for that device. This is particularly useful for devices that need a static IP address for reliable network communication, such as printers, servers, or any critical workstation. By using reservations, network administrators can manage IP assignments centrally through the DHCP server rather than manually configuring static IPs on each device, thus reducing the likelihood of IP conflicts and ensuring that the same devices always receive the same IP address without requiring extensive configuration on each individual device.
