Which of the following best describes a DHCP server?

A DHCP server is primarily responsible for assigning IP addresses dynamically to devices on a network. This function is essential for managing the IP address allocation process, enabling devices to communicate within a network without the need for manual configuration. When a device connects to the network, the DHCP server provides it with a unique IP address from a predefined pool of addresses, along with other configuration information such as subnet mask, default gateway, and DNS servers.

This dynamic allocation enhances network efficiency and simplifies administrative tasks, especially in environments with a high number of devices, or when devices are frequently added or removed. By automating IP address management, DHCP servers reduce the risk of address conflicts and ensure that devices can join the network seamlessly.

Other options, while related to networking, serve different functions. For instance, servers that store website data are more related to web hosting, routing servers facilitate data transfer across networks, and traffic monitoring servers help analyze and manage internet traffic; none of these accurately describes the specific role of assigning IP addresses, which is the core function of a DHCP server.
