Your company has a branch office that contains a Windows Server 2008 R2 server.
The server runs Windows Server Update Services (WSUS).
The company opens four new satellite offices. Each satellite office connects to the branch office by using a
dedicated WAN link.
You need to design a strategy for patch management that meets the following requirements:
WSUS updates are approved from a central location.
WAN traffic is minimized between the branch office and the satellite offices.
What should you include in your design?
A.
In each satellite office, install a WSUS server. Configure each satellite office WSUS server as a replica of
the branch office WSUS server.
B.
In each satellite office, install a WSUS server. Configure each satellite office WSUS server as an
autonomous server that synchronizes to the branch office WSUS server.
C.
On the branch office WSUS server, create a computer group for each satellite office. Add the client
computers in each satellite office to their respective computer groups.
D.
For each satellite office, create an organizational unit (OU). Create and link a Group Policy object(GPO) to
each OU. Configure different schedules to download updates from the branch office WSUS server to the
client computers in each satellite office.
Explanation:
WSUS SERVER LAYOUT
You can connect WSUS servers in Autonomous mode (toachieve distributed administration) or in Replica
mode (to achieve centralized administration). You do not have to deploy a server hierarchy that uses only one
mode: you can deploy a WSUS solution that uses bothautonomous and replica WSUS servers.
Autonomous mode (Distributed Administration)
Distributed management by using autonomous mode is the default installation option for WSUS. In
autonomous mode, an upstream WSUS server shares updates with downstream servers during
synchronization. Downstream WSUS servers are administered separately and they do not receive update
approval status or computer group information from the upstream server. By using the distributed management
model, each WSUS server administrator selects update languages, creates computer groups, assigns
computers to groups, tests and approves updates, and makes sure that the correct updates are installedto the
appropriate computer groups.
Replica mode (Centralized Administration)
In replica mode, an upstream WSUS server shares updates, approval status, and computer groups with
downstream servers. Downstream replica servers inherit update approvals and are not administered separately
from the upstream WSUS server. If you set up several replica servers to connect to a single upstream W SUS
server, do not schedule synchronization to run at the same time on each replica server. This practice will avoid
sudden surges in bandwidth usage.
