Question

Quizplus · Accepted Answer

When an internal DNS server receives queries to resolve domain names on the Internet, it can use a forwarder to send the query to an external DNS server that can resolve the domain name. This helps to reduce the load on the internal DNS server and improve the response time for clients.

Answer: C
 A forwarder can also be used to make use of a server that caches the results of DNS queries. This can improve the response time for clients by providing them with cached results instead of having to query multiple DNS servers for the same information.
