Designing and Implementing a Server Infrastructure — Question 29

A new company registers the domain name of contoso.com. The company has a web presence on the Internet. All Internet resources have names that use a DNS suffix of contoso.com.
A third-party hosts the Internet resources and is responsible for managing the contoso.com DNS zone on the Internet. The zone contains several hundred records.
The company plans to deploy an Active Directory forest.
You need to recommend an Active Directory forest infrastructure to meet the following requirements:
✑ Ensure that users on the internal network can resolve the names of the company's Internet resources.
✑ Minimize the amount of administrative effort associated with the addition of new Internet servers.
What should you recommend?

Answer options

• A. A forest that contains a single domain named contoso.local
• B. A forest that contains a root domain named contoso.com and another domain named contoso.local
• C. A forest that contains a root domain named contoso.com and another domain named ad.contoso.com
• D. A forest that contains a single domain named contoso.com

Correct answer: A

Explanation

The correct answer is A, as using a single domain named contoso.local allows for separation from the public DNS and ensures internal resolution without conflict. Options B and C introduce additional complexity and administrative overhead by mixing public and private domains. Option D is incorrect because it would not allow internal users to resolve Internet resource names effectively.
