Why each option
A DNS server's primary capability is to translate human-readable hostnames into their corresponding numerical IP addresses, enabling devices to locate resources on a network.
Assigning an IP address to a host is a function of a DHCP (Dynamic Host Configuration Protocol) server, not a DNS server.
Converting an IP address into a MAC address is the function of the ARP (Address Resolution Protocol) or RARP (Reverse ARP) at the data link layer, not a DNS server.
While DNS associates hostnames with IP addresses, it does not assign a hostname to a host; hostnames are typically configured on the host itself or through directory services.
The fundamental capability of a Domain Name System (DNS) server is to perform name resolution, which involves converting a Fully Qualified Domain Name (FQDN) or hostname (e.g., www.example.com) into its corresponding IP address (e.g., 192.0.2.1 or 2001:db8::1). This allows clients to connect to services using memorable names instead of numerical IP addresses.
