Your network consists of a single Active Directory forest that contains two domains as shown in the image.
Server 1 has london.salespoint.com as the primary DNS zone and paris.salespoint.com as the secondary DNS zone with an IP address of 192.168.4.1. Server 2 has paris.salespoint.com as the primary DNS zone and london.salespoint.com as the secondary DNS zone with an IP address of 192.168.6.1.
How should you configure the primary and secondary DNS address referrals on the client computers in the Paris office to ensure that users have access to the Internet with as few network hops as possible?
