Queries on SQL Data Sync

Question

Hi,
One of our customers had the following query on SQL Data Sync
1. ALter database permission is required during setup of sync services and it switches ON the SNAPSHOT ISOLATION level on our on premise DB. what is the impact of it?
2. After setting up the SNAPSHOT ISOLATION LEVEL ON, it creates tracking tables, some SPs, and triggers and set read commited isolation level multiple times. Is there a way that these
objects will be created in some other DB and not on the main OLTP so that we can avoid cluttering the main DB with tracking tables, triggers, SPs ets?
3. As the SNAPSHOT isolation level is introduced in SQL 2005 onwards and is for maintaining row versions in TEMP DB. Does it mean switching it on at DB level, it's going to maintain the
row and transaction version for all DB objects in TEMP DB , irrespective of whether they are part of sync group or not?
Any pointers on this would be appreciated.
Cheers!

Hi Harish,
For the knowledge about SNAPSHOT ISOLATION, please check the detail here:

For the objects created on the database, they cannot be created on other database since the objects need to visit the source database data.
Actually those objects are required by sync framework, you can find more details here:
