سؤال مشكوك بجوابه في TESTKING 70-291

(H) يا شباب MCSE في سؤال أنا شاكك بجوابه إذا كان صح أو خطأ و السؤال هو:
You are the network administrator for TestKing.com. The network consists of a
single Active Directory domain named testking.com. All servers run Windows
Server 2003. All client computers run either Windows 2000 Professional or
Windows XP Professional.
TestKing has offices in San Francisco, Los Angeles and London. Each office
contains three servers that are configured as domain controllers and run the DNS
Server service. All client computers and servers are configured to use a local DNS
server as the primary DNS server.
You create a new primary zone named east.testking.com on a server in London
named Testking1.
You need to configure DNS servers in San Francisco and Los Angeles to resolve
queries for resources in east.testking.com. You must ensure that client computers
can update DNS data on the local DNS servers. You also need to minimize WAN
network traffic relating to DNS queries for resources in east.testking.com.
What should you do?
