Question

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.contoso.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, you create a conditional forwarder for contoso.local and west.contoso.local. 

On Server3, you create a conditional forwarder for contoso.local and east.contoso.local.

Does this meet the goal?

Proposed answer
  • A. Yes
  • B. No
Suggested answer
  • A. Yes
Correct answer

The suggested answer is correct

All DNS servers should have configured forwarding to zones of each other

YES- Delegation tells S1 how to find S2 and S3. Cond forward from S2 to S1/S3 and from S2 to S1/S3 allows all internals to resolve. And they can all find internet hosts because theyre using root hints. Please correct me if needed.

looks nice, on the S2 and S3 (east and west) perspective everything is fine. one doubt, Server1 how is going to solve names in east and west?

Indeed, the solution you provided meets the goal. By creating conditional forwarders on Server2 and Server3, you ensure that DNS resolution for the internal namespaces (such as east.contoso.local and west.contoso.local) is handled correctly. This approach allows you to resolve both internal namespaces and internet hosts effectively.

There are root hints so it will work (A). Ineffectively but it will work

Again, the solution has to enable each DNS server to resolve names in all three domains. Forwarding will resolve the name for the client, but that is passing the responsibility to another DNS server, therefore not meeting the requirements of the solution.

only partial correct statement. the DNS server requests the information, then adds it to the local cache and then sends the information to the client.

My answer is B : when you create a conditional forwarding for east and west to the parent domain. It has all the information for dns. so when west queries anything it should query the parent domain and from there to east.

Yes as this "resolve the names of all the internal namespaces" since both parent and child domains are included

The solution of creating conditional forwarders on Server2 and Server3 for contoso.local and east.contoso.local or west.contoso.local, respectively, does meet the goal. Since all the DNS servers are already using root hints, they will be able to resolve internet host names. By creating the conditional forwarders, the DNS servers will be able to resolve the names of all the internal namespaces as well. By configuring conditional forwarders, the DNS servers can forward DNS queries for specific domains to specified DNS servers, improving the efficiency and speed of name resolution for those domains.

No. How s2 know the IP o S1 and S3 etc.

Nvm. After pondering on the "english", it didn't explicitly say what kind of input they gonna add into the forward but they are entering the such inputs for these two zones. So the answer is Yes.

No, i think because Root Hits is in use, so the forwarding fot contoso.com is not necessary https://docs.microsoft.com/en-us/windows-server/identity/ad-ds/plan/reviewing-dns-concepts

Root Hits answers queries regarding registered domains, not local as contoso.com. Answer is Yes

It will work, cause all use root hints for the internet.

No, it won't satisfy the need to resolve names from the internet.
