Hi Team

As part of an earlier That I did with Databricks team , I got the info for that if one wants to dump the data in unity catalog schema from a DLT pipeline , The specific schema's Storage location must not be specified . else he DLT pipeline will fail at the "waiting Resources" stage.
Question 1: I want to know if DLT picks up a location by default in Unity catalog where is this location. Does it store the data files in the ADLS location tagged to the meta store? 

Question2: if I have two catalogs(say for business module 1 and business module 2)  tagged to same meta store, and I want to adopt DLT pipeline for business module1, would the users of business module2 have access to data of business module 1. Is there any access concern ?
