Your company uses the internet domain westsim. Your network has a single Active Directory domain named westsim. local. You manage your network's DNS servers for the westsim zone and the westsim. local zone. All Domain Name Service (DNS) servers on your network run Windows Server 2016.

You want to minimize administrative effort and communication between the two divisions as the Asia division installs DNS servers. To support this goal, you need to make appropriate configurations on the DNS servers that you manage. What should you do?
