Explanation
The correct arrangement maps each DNS lookup component to its specific function: 'DNS' refers to the protocol/service used for name resolution, 'cache' stores previously resolved queries to speed up future lookups, 'name resolver' is the client-side component that initiates DNS queries, 'domain' specifies the default domain name appended to unqualified hostnames, and 'no ip domain-lookup' is the IOS command that disables DNS lookup on a Cisco router to prevent unwanted lookup delays when mistyped commands are interpreted as hostnames. Each component plays a distinct role in the DNS resolution process on Cisco devices.
