Answer 2

Answer:

From the above given options, the one which is true for DNS name resolution is - option d) All of these.

The process in which, an unique Internet Protocol address that is in textual form is being translated to an Internet Protocol address is called DNS resolution.

In case of iterative resolution , multiple DNS requests are sent to many DNS servers.

In case of recursive resolution only one DNS request is being sent to an immediate DNS server of its root.

For better performance distribution of load and aliasing of host is being done.
