• A、In each satellite office， install a WSUS server. Configure each satellite office WSUS server as an  autonomous server.
• B、In each satellite office， install a WSUS server. Configure each satellite office WSUS server as a replica  of the branch office WSUS server.
• C、In each satellite office， install a WSUS server. Configure each satellite office WSUS server to use the  branch office WSUS server as an upstream server.
• D、For each satellite office， create organizational units （OUs）. Create and link the Group Policy objects  （GPOs） to the OUs. Configure different schedules to download updates from the branch office WSUS  server to the client computers in each satellite office.
