Hi,
Thank you for posting in Symantec community.
I would be glad to answer your query.
Q. I have 4 countries > each countries has 10 groupings. Does it mean that I need to have 10 GUP client for each group
--> Not necessary it totally depends upon business requirement. I would request you to understand the concept of Group update provider.
Ideally each country can have single SEPM and each location can have a GUP.
You can configure several different types of Group Update Providers in the LiveUpdate Settings policy: a single Group Update Provider, an explicit list of Group Update Providers, and multiple Group Update Providers. The types of Group Update Provider are not mutually exclusive. You can configure one or more type of Group Update Provider per policy.
