You are the network administrator for the ABC Company. Your network consists of two DNS servers named DNS1 and DNS2. The users who are configured to use DNS2 complain because they are unable to connect to internet websites. The following shows the configuration of both servers:

Server Configurations:

DNS1: _msdcs.abc.comabc.com
DNS2: .(root)_msdcs.abc.comabc.com

The users connected to DNS2 need to be able to access the internet. What should be done?

Delete the .(root) zone from the DNS2. Then configure conditional forwarding on the DNS2 server. If this is not done, the users will be unable to access the internet.

Explanation:

DNS forwarding enables DNS queries to be forwarded to a designated server, say DNS2, for resolution according to the DNS domain name. This stops the initial server, DNS1, that was contacted by the client from handling the query, thereby improving the network's performance and resilience and enabling the users to be connected to the DNS2 in order to access the internet.
