GUP, SEPM and Symantec Live update are all configured for virus definitions

 Hi,

I have more than 20 GUP servers globally and one SEPM with more than 10 000 Sep clients and a SQL Server. All my GUP servers are configured as shown below, with all the options checked.

Questions:

1. Where will the Sep clients download the updates from, Will they get them from SEPM or Liveupdate server or the Gup servers.
2. What impact will this have on my environment, is it good or bad.

Please advise as I am not sure whether to live these settings as they are or make changes.
