What is the purpose of the Dynamic Host Configuration Protocol (DHCP)?

The Dynamic Host Configuration Protocol (DHCP) is a network management protocol used primarily for automating the process of configuring devices on IP networks. The primary purpose of DHCP is to automatically assign IP addresses to devices on a network, ensuring that each device can communicate with others on the network and on the internet without requiring manual configuration.

When a device, such as a computer or smartphone, connects to a network, DHCP enables it to request an IP address from a pool of available addresses managed by a DHCP server. This server then assigns an appropriate IP address to the device along with other necessary network parameters such as the subnet mask, default gateway, and Domain Name System (DNS) server information. This process simplifies network administration, reduces potential errors in IP address configuration, and facilitates easier management of devices joining or leaving the network.

In contrast, the other choices describe functions that are not related to DHCP's main purpose. Assigning static IP addresses, creating backups of IP addresses, and managing encryption keys are outside the scope of what DHCP is designed to do. Static IP assignments require manual configuration, backup of IP addresses is typically a function of network management or documentation processes, and encryption key management relates to network security protocols distinct from DHCP. This distinction highlights why DHCP's
