QUESTION 344
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.
The other record points to the IP address of Server2.
All users access the website by using the URL http://web.litwareinc.com.
You discover that the client computers on Subnet1 always connect to Server1 when they access the URL http://web.litwareinc.com.
You need to ensure that all of the client computers are distributed randomly between Server1 and Server2 when accessing the URL http://web.litwareinc.com.
What should you do?

A.    Modify the time-to-live (TTL) value for the A records of Server1.litwareinc.com and

B.    Disable DNS round robin on DC1.
C.    Disable netmask ordering on DC1.
D.    Modify the time-to-live (TTL) value for the A records ofweb.litwareinc.com.

Answer: C
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.
