license profile for the associated domain

[FireChief]

I’m planning to introduce the “associated domain” into our company’s Zoom settings. But, before getting started, I’d like to ask the following two questions:

1  Is it possible to have Pro licenses, Business licenses, and Basic licenses within the same Zoom account? For example, are we allowed to have 10 Pro licenses, 2 Business licenses, and 100 Basic licenses in the same account?

2  Assuming the answer to the above question is positive, is it possible for an admin user with a Business license to manage the associated domain settings?
