All servers on the ABC.com network run Windows Server 2003 and all client computers run
Windows XP Professional. The Active Directory forest operates at Windows Server 2003 level.
ABC.com has a head office in Chicago and several branch offices. Each office contains a domain
controller and is configured as an Active Directory Site. Every domain controller also serves as a
DNS server. The branch offices access the resources in the Chicago office via a 128-Kbps WAN
connection.
You received a report from branch office users that they cannot access the Chicago office
resources during peak business hours.
How can you solve the logon issues while ensuring Active Directory replication traffic across the
WAN links is kept to a minimum?
A.
Configure Conditional Forwarding on the branch office DNS servers.
B.
Install an additional domain controller in each branch office.
C.
Configure the SRV records in the DNS zone on each domain controller to point to the local
domain controller.
D.
Configure universal group membership caching for each branch office.
E.
Configure the branch office domain controllers as Global Catalog servers.
Explanation:
When a user logs on to the network, the global catalog provides universal group
membership information for the account to the domain controller processing the user logon
information. If a global catalog is not available when a user initiates a network logon process, the
user is able to log on only to the local computer unless the site has been specifically configured to
cache universal group membership lookups when processing user logon attempts. In this scenario
the domain controller must contact the global catalog server across a WAN link that is saturated.
Enabling universal group membership caching will overcome this problem.
