Your company has an Active Directory forestthat contains two domains.
The forest hasuniversal groupsthat contain members from each domain.
A branch officehas a domain controllernamed DC1.
Users at the branch office report that the logon process takes too long.
You need to decrease the amount of time it takes for the branch office users to logon.
What should you do?
A.
Configure DC1 as a Global Catalog server.
B.
Configure DC1 as a bridgehead server for the branch office site.
C.
Decrease the replication interval on the site link that connects the branch office to the corporate network.
D.
Increase the replication interval on the site link that connects the branch office to the corporate network.

What Is the Global Catalog?
The global catalog is a distributed data repositorythat contains a searchable, partial representationof every
object in every domain in a multidomain Active Directory Domain Services (AD DS) forest. The global catalog is
stored on domain controllers that have been designated as global catalog servers and is distributed through
multimaster replication. Searches that are directed to the global catalog are fasterbecause they do not
involve referrals to different domain controllers.
In addition to configuration and schema directory partition replicas, every domain controller in a forest stores a
full, writable replica of a single domain directorypartition. Therefore, a domain controller can locate only the
objects in its domain. Locating an object in a different domain would require the user or application to provide
the domain of the requested object.
The global catalog provides the ability to locate objects from any domain without having to know the domain
name. A global catalog server is a domain controller that, in addition to its full, writable domain directory
partition replica, also stores a partial, read-onlyreplica of all other domain directory partitions in the forest. The
additional domain directory partitions are partial because only a limited set of attributes is included for each
object. By including only the attributes that are most used for searching, every object in every domain in even
the largest forest can be represented in the database of a single global catalog server.
