Before you deploy the SDDC by following this validated design, you must create a DNS configuration of fully qualified domain names (FQDNs) and map them to the IP addresses of the management application nodes. 

In a multi-region deployment with domain and forest structure, you must assign own IP subnets and DNS configuration to each sub-domain, sfo01.rainpole.local and lax01.rainpole.local. The only DNS entries that reside in the rainpole.local domain are the records for the virtual machines within the network containers that support disaster recovery failover between regions such as vRealize Automation and vRealize Operations Manager.
