Actual exam question from Microsoft's 70-345

Question #: 108
Topic #: 1

Your company has one Exchange Server 2016 database availability group (DAG) across two data centers.
You need to load balance a single namespace across both data centers. The solution must be able to check service health check.
Which two solutions should you use? Each correct answer presents part of the solution.

A. A Layer 7 load balancer
B. An unbound model
C. A bound model
D. DNS round-robin

Show Suggested Answer

Suggested Answer: AB 🗳️
You should use an unbound model. With an unbound model, a single namespace is used across two datacenters.
You should use a Layer 7 load balancer. In this scenario, a DAG has active databases across two datacenters.
Users are distributed with a load balancer across the two datacenters.
A Layer 7 load balancer checks service health at the application level.
You should not use a bound model. A bound model uses two separate namespaces across two datacenters.
You should not use DNS round-robin. DNS round-robin load balancing uses a single namespace, but it does not check the health of the application or server.
