That is correct for AVB as well as for the other RTP/IP (layer 3) based
transports such as Dante, Livewire, Ravenna, etc.

Correct

If you have access to IEEE specs see IEEE 1588-2008 and IEEE 802.1AS.
802.1AS is a profile of 1588-2008, there is what is known as "best master
clock algorithm" to select the best clock.  If multiple devices are
advertising equivalent quality ranking there is a tie breaker, I think
based on MAC address, but don't  quote that, I am going from memory and
have not looked at the details in quite a while.
