Designing and Implementing a Server Infrastructure — Question 34

Your network contains an Active Directory forest named contoso.com.
You plan to add a new domain named child.contoso.com to the forest.
On the DNS servers in child.contoso.com, you plan to create conditional forwarders that point to the DNS servers in contoso.com.
You need to ensure that the DNS servers in contoso.com can resolve names for the servers in child.contoso.com.
What should you create on the DNS servers in contoso.com?

Answer options

• A. A zone delegation
• B. A conditional forwarder
• C. A root hint
• D. A trust point

Correct answer: A

Explanation

Creating a zone delegation on the DNS servers in contoso.com allows them to delegate the resolution of queries for child.contoso.com to the appropriate DNS servers in that domain. The other options do not facilitate the necessary resolution; a conditional forwarder would direct queries in the opposite direction, a root hint is for resolving names outside the local network, and a trust point is related to security rather than DNS resolution.
