A system administrator needs to specify a set of FQDN to IP address mappings for a legacy server; the administrator does not want the legacy server to be referenced by other servers. Which of the foll

A DHCP server assigns IP addresses and other network configurations, but it does not manage FQDN to IP mappings in the way described for local resolution.

A DNS server provides FQDN to IP mappings for an entire network or domain, making the server publicly resolvable by other machines, which contradicts the requirement of not being referenced by other servers.

The host file is a local text file on an operating system that maps hostnames to IP addresses, acting as a local DNS resolver for that specific machine. By modifying the host file on the legacy server, the administrator can ensure that only this server resolves certain FQDNs to specific IP addresses, without broadcasting these mappings to other servers or the entire network via a central DNS server. This allows for isolated name resolution configurations for a single system.

Route statements define network paths for IP packets and are not used for FQDN to IP address resolution.
