The correct answer is B. No. The proposed DNS solution does not satisfy the requirement because at least one DNS server cannot resolve all internal namespaces and internet names given the zone delegation and root hints configuration.

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.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?

Why each option
The proposed DNS solution does not satisfy the requirement because at least one DNS server cannot resolve all internal namespaces and internet names given the zone delegation and root hints configuration.
The solution does not fully meet the stated goals because the DNS configuration has a gap that prevents at least one server from resolving all internal and internet names.
The solution fails because DNS servers using only root hints cannot automatically resolve internally delegated zones like east.contoso.local and west.contoso.local unless the delegating server (hosting contoso.local) is reachable and delegation records are properly configured; without forwarders or stub zones to bridge internal resolution, not all servers can resolve every namespace.
