Designing and Deploying Microsoft Exchange Server 2016 — Question 124

A new company has the following:
✑ Two offices that connect to each other by using a low-latency WAN link
✑ In each office, a data center that is configured as a separate subnet
✑ Five hundred users in each office.
You plan to deploy Exchange Server 2016 to the network.
You need to recommend which Active Directory deployment to use to support the Exchange Server 2016 deployment.
What is the best recommendation to achieve the goal?

Answer options

• A. Deploy two forests that each contains one site and one site link. Deploy two domain controllers to each forest. In each forest configure one domain controller as a global catalog server
• B. Deploy one forest that contains one site and one site link. Deploy four domain controllers. Configure all of the domain controllers as global catalog servers.
• C. Deploy one forest that contains two sites and two site links. Deploy two domain controllers to each site in each site, configure one domain controller as a global catalog server
• D. Deploy one forest that contains two sites and one site link. Deploy two domain controllers to each site. Configure both domain controllers as global catalog servers

Correct answer: D

Explanation

The correct answer is D because deploying one forest with two sites and a single site link allows for efficient management of the two offices while ensuring redundancy with two domain controllers in each site. This configuration also allows both domain controllers to act as global catalog servers, which is beneficial for user authentication and directory lookups. Options A, B, and C do not provide the same level of redundancy and efficiency needed for the network's requirements.
