The correct answer is B. No. This question tests whether a proposed DNS configuration correctly enables all three internal servers to resolve both delegated internal namespaces and internet names.

Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution. After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen. 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: You configure Server2 and Server3 to forward DNS requests to 10.0.1.10. Does this meet the goal?

Why each option
This question tests whether a proposed DNS configuration correctly enables all three internal servers to resolve both delegated internal namespaces and internet names.
Answering Yes is incorrect because the described configuration leaves at least one DNS server unable to resolve all internal delegated namespaces or internet names, meaning the goal is not fully achieved.
The proposed solution does not fully meet the requirements because at least one DNS server lacks the necessary forwarders or stub zones to properly follow the zone delegations for east.contoso.local and west.contoso.local to their authoritative servers. Without conditional forwarders or stub zones pointing each non-authoritative server to the correct authoritative server for each delegated zone, internal name resolution will fail for those namespaces on the affected server.
Concept tested: DNS zone delegation and stub zone or conditional forwarder resolution
