Your network has a single Active Directory domain named westsim.local. All westsim.local authoritative DNS servers are configured to forward DNS requests across a firewall to a public DNS server. All client computers are members of the westsim.local Active Directory domain and are configured to use westsim.local authoritative DNS servers.

Your company has opened one new site in South America. The South America site has its own internet connection and uses a dedicated wide area network $($WAN$)$ link to company headquarters in North America for intranet traffic.

The WAN link between company headquarters in North America and the South America site is expensive and somewhat unreliable. DNS traffic across this WAN link must be minimized. You need to make appropriate DNS configurations to meet this requirement.
