Question
Your network contains an Active Directory domain named litwareinc.com. All domain controllers and servers run Windows Server 2008 R2 Service Pack 1 (SP1). A domain controller named DC1 hosts a primary zone for litwareinc.com. You have two servers named Server1 and Server2. Both servers host the same website. Server1 is located on a subnet named Subnet1. Server2 is located on a subnet named Subnet2. You create two host (A) records for web.litwareinc.com. One record points to the IP address of Server1.

Explanation
Round robin: Determines whether the DNS server uses the round robin mechanism to rotate and reorder a list of resource records if multiple resource records exist of the same type that exist for a query answer. By default, the DNS Server service uses round robin. Netmask ordering: Determines whether the DNS server reorders address (A) resource records within the same resource record that is set in the server's response to a query based on the Internet Protocol (IP) address of the source of the query. By default, the DNS Server service uses local subnet priority to reorder A resource records.
