Which of the following is a key feature of dynamic host configuration protocol (DHCP)?

Dynamic Host Configuration Protocol (DHCP) is fundamentally designed to automate the process of assigning IP addresses to devices on a network. This automation ensures that devices can connect to the network without the need for manual configuration. When a device connects to a network, DHCP enables it to request an IP address, and the DHCP server then assigns an available address from a predefined pool. This process simplifies network management and reduces the potential for IP address conflicts, making it an essential feature for modern networks.

The other options do not accurately represent the primary function of DHCP. The assignment of static IP addresses is typically managed differently and involves manual configuration, while encryption of data over networks is related to security protocols rather than DHCP. Additionally, the management of domain name services is handled by DNS, which is a separate system from DHCP.
