We have configured two managed Metadata services in our SharePoint 2010 Farm, named MMS1 & MMS2 and both has its own proxy service.

**Question:1<br/>**
MMS1 has a termset group - MMS1_TG1<br/>
MMS2 has a termset group - MMS2_TG1

If I open any of the MMS, it shows both MMS1_TG1 & MM2_TG1. How is this possible as both of those are in different DBs.


**Question:2<br/>**
MMS1 is associated with Default proxy group.<br/>
MMS2 is associated with Custom proxy group.<br/>


Default proxy group is associated with a Webapplication - MyDemo. If I open a Metadata management tool in Mydemo webapplication, I could see again both the Termset Group MMS1_TG1 & MMS2_TG1. 

How is this possible, The Webapplication Mydemo is just connected only with MMS1 through the proxy group default and how I could see both the termset group from two different MMS?


**Question:3<br/>**
As per the Microsoft article, User should be able to view his local & global (associated with the webapplication). 

If I want to hide a global termset group from the enduser, what has to be done?

**Question:4<br/>**
Should I need to give Read permission to All authenticated Users in the MMS Administrator section?

**Note:**
I have only one service account in my entire Farm.
Application pool uses the same service account used as a Farm account.
