Explanation:
The DNS server is said to be a caching-only DNS server.
A caching-only Domain Name System server, works by recieving queries from the client, proceeds to perform queries against other named servers, then caches the results and returns the results to the client.
Subsequent queries are resolved and returned for the specified host straight from the the cache, by the server, instead of submitting to the external server.
The advantage of this process is that it reduces traffic from outgoing DNS and speeds up the name resolution. Also, there is a reduction in the amount of query traffic.
