Your network contains an Active Directory domain named contoso.com. All domain controllers run Windows
Server 2012 R2.
The network has the physical sites and TCP/IP subnets configured as shown in the following table.
You have a web application named App1 that is hosted on six separate Web servers. DNS has the host names
and IP addresses registered as shown in the following table.
You discover that when users connect to appl.contoso.com, they are connected frequently to a server that is
not on their local subnet.
You need to ensure that when the users connect to appl.contoso.com, they connect to a server on their local
subnet. The connections must be distributed across the servers that host appl.contoso.com on their subnet.

I think it is wrong answer. It should be A.Run dnscmd and specify the CacheLockingPercent parameter.
CacheLockingPercent parameter is “100%” as Default. It means cannot overwrite the DNS record on the cache. As the result, DNS server returns the old IP address if the IP address has been changed to the new one.
So you should change the parameter and allow the overwrite of DNS record cache.
