Which of the following is a function of the DHCP server?

The function of a DHCP server primarily involves the automatic assignment of IP addresses to devices within a network. Dynamic Host Configuration Protocol (DHCP) enables network administrators to manage IP address allocation efficiently without manual configuration on each device. When a device connects to the network, it sends a request to the DHCP server, which then provides an available IP address along with other network configuration details such as subnet mask and default gateway, allowing the device to communicate effectively on the network.

The process of dynamic IP address assignment also aids in conserving the IP address pool and ensuring that devices can join the network seamlessly, promoting scalability in network management. Thus, option B accurately represents the critical role of DHCP servers in network infrastructure.
