Designing and Deploying Microsoft Exchange Server 2016 — Question 112

You manage an Exchange Server 2016 organization in an Active Directory forest that contains three sites.
The sites are located in Chicago, Los Angeles, and New York.
A database availability group (DAG) named DAG1 contains eight mailbox servers in the Los Angeles site and eight mailbox servers in the New York site.
The servers run Windows Server 2012 R2. The Los Angeles and New York sites both have independent network access to the Chicago site.
You need to configure the environment to provide the organization with the best chance of surviving a service outage if a site or a WAN link fails.
Additionally, the New York site must be considered the primary data center and given preference for survival.
Which two actions should you perform? Each correct answer presents part of the solution.

Answer options

• A. Add an additional Exchange server to DAG1 and place it in the New York site.
• B. Place the cluster core resource group in the Chicago site.
• C. Place the file share witness in the Chicago site.
• D. Add an additional Exchange server to DAG1 and place it in the Chicago site.
• E. Place the cluster core resource group in the New York site.
• F. Place the file share witness in the New York site.

Correct answer: C, E

Explanation

Placing the file share witness in the Chicago site (option C) ensures that it is accessible to both the Los Angeles and New York sites, thus maintaining quorum in case of a site failure. Positioning the cluster core resource group in the New York site (option E) prioritizes the New York site as the primary data center, which is essential for meeting the requirement of giving it preference for survival during outages. The other options either do not enhance redundancy effectively or do not align with the requirement to prioritize the New York site.
