Replication Manager with Exchange 2010 Native DAG questions

I want to make sure that I have the Exchange 2010 Native DAG requirements correct:

1. We would add the Exchange server's DAG name instead of each server's name in RM, correct?

2. How do we differentiate between active/passive copies if #1 is correct? For example, I have Exchange-A which hosts 4 active and 4 passive (from Exchange-B) DBs. Exchange-B hosts 4 active and 4 passive (from Exchange-A) DBs as well. I want to set up a job so that the snaps/clones are taken from the passive copy. Will I be able to choose the 4 active DBs on Exchange-A and 4 active DBs on Exchaneg-B?

3. I want RM to truncate the logs so I will choose the "Online Full" option when configuring the RM job. If I create clones off of the passive copy will RM truncate the logs on the active DB copy?

Thank you in advance.
