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.
Correct Answer: A

WSUS SERVER LAYOUT
You can connect WSUS servers in Autonomous mode (to achieve 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 both autonomous 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 installed to 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 WSUS server, do not schedule synchronization to run at the same time on each replica server. This practice will avoid sudden surges in bandwidth usage.
