You are planning the deployment of DNS to a new network.
You have three internal DNS servers as shown in the following table.
The contoso.local zone contains zone delegations for east.conloso.local and west.contoso.local. All the DNS servers use root hints.
You need to ensure that all the DNS servers can resolve the names of all the internal namespaces and internet hosts.
Solution: On Server2 and Server3, you configure a conditional forwarder for contoso.local.
Does this meet the goal?
- A. Yes
- B. No
B. No
The suggested answer is correct, proposed solution not enough.
in addition for solution we need two additional forwarders:
- east.contoso.local -> west.contoso.local
- west.contoso.local -> east.contoso.local

I say NO because it's not sufficient; You *do* need to have S1 as a conditional forwarder for S2 and S3... but S2 and S3 also need to be set up as cond. forwarders for EACHOTHER, otherwise they wont be able to find eachother. S2 and S3 would NOT be able to find eachother via S1 as a result of delegation.. In fact, delegation prevents it; Since they are delegates of S1, they are authoritative for their own domains.. contoso.locol/S1 is no longer authoritative over them, so it could not help S2 find S3 or vice versa. Please correct me if needed.

No, this solution would not meet the goal. A conditional forwarder is used to forward DNS requests to specific DNS servers based on the domain name queried. By configuring a conditional forwarder on Server2 and Server3 for contoso.local, it would only forward requests for that specific domain to another DNS server, but it would not ensure that all the DNS servers can resolve the names of all the internal namespaces and internet hosts.

No. Conditional forward can work, make no mistake but the problem here is they are forwarding to a domain name, not a ip address. How they know the IP address of the domain they don't know?

Nvm. After pondering on the "english", it is saying that it only create condition forwarding for one zone while excluding the other zone. So the answer still B.

In order for this question to be true, the dns replication must be for forestdns zones- otherwise this must be false , without creating addtional zones in the child domain, and the forwarder back to the parent- https://blogs.msmvps.com/acefekay/2010/10/01/dns-parent-child-dns-delegation-how-to-create-a-dns-delegation/

Things is that this is trick question. You cannot create conditional forwarder for zone that already exist. You usually create cond. forwarders to resolve dns queries from another forest domain , that usualy have another dns name.
