Which of the following is NOT TRUE in the context of Domain Name Server (DNS)?
Answer and explanation
Correct answer D
In the Domain Name System (DNS), when an application invokes the resolver to map a domain name to an IP address, the resolver sends a query packet to the local DNS server and receives the reply using UDP packets (on port 53) rather than TCP packets. Therefore, "The query and response messages are sent as TCP packets." is not true.
