datacenters. Datacenter 1 is used for production and Datacenter 2 is used for disaster recovery

Datacenter 1 are offline or are running a full load.

A.
Create a preferential load balancing policy.

B.
Create and assign a custom load evaluator at each datacenter.

C.
Create an OU, a worker group and a zone for each datacenter’s servers.
