You have been hired to design a TCP/IP-based network that will contain both Unix and Windows computers. You are planning a name resolution strategy. Which of the following services will best suit…
The correct answer is C. DNS. DNS (Domain Name System) is the only name resolution service that operates across both Unix and Windows platforms, making it the correct choice for a mixed-OS TCP/IP network.

Why each option
DNS (Domain Name System) is the only name resolution service that operates across both Unix and Windows platforms, making it the correct choice for a mixed-OS TCP/IP network.
APIPA (Automatic Private IP Addressing) assigns IP addresses in the 169.254.x.x range when a DHCP server is unavailable - it does not perform name resolution.
LMHOSTS is a static file used for NetBIOS name resolution and is specific to Windows environments, not suitable for Unix hosts.
DNS is a platform-neutral, standards-based name resolution protocol (RFC 1034/1035) that operates natively on both Unix and Windows systems. It resolves hostnames to IP addresses for any TCP/IP-based host regardless of operating system, making it the ideal solution for heterogeneous networks.
DHCP dynamically assigns IP addresses and related configuration parameters but does not perform hostname-to-address name resolution.
WINS (Windows Internet Name Service) resolves NetBIOS names and is a Windows-proprietary service that does not natively support Unix clients.
