You are planning an Exchange Server 2013 Deployment.
You plan to install exchange servers in two sites, SiteA and SiteB. You plan to add all exchange
servers to a single database availability group (DAG) and have all of the databases replicated to all
servers.
You implement the load balancers as configured in the following table:
You need to plan a solution that automatically allows all users to connect to their mailbox if all of the
exchange servers in one site fail.
What should you include in the plan?
A.
Create two host (A) records named mail.fabrikham.com that each point to one of the VIP’s.
B.
Change the DAG settings of AllowCrossSiteRPCAccess to $True.
C.
Create one host (A) record named site1.fabrikham.com that points to 192.168.1.10 and create
one host (A) record named site2.fabrikham.com that points to 192.168.2.10.
D.
Change the DAG setting of DatabaseAvailabilityGroupConfiguration to $Null.
this seems right, if you did C users would not be able to connect if their site fails as they will be looking at a load balancer in a failed site (unless you made changes to the DNS record to point to the other site manually).
Use DNS round robin to make this automatic
