Explanation:

The Domain Name System (DNS) role is a role that provides a standard method for
associating names with numeric Internet addresses. This lets users refer to network
computers by using easy-to-remember names instead of a long series of numbers. Windows
DNS services can be integrated with DHCP services, eliminating the need to add DNS
records as computers are added to the network.
