how are layers and scenes treated in unity networking?

i am working on a multiplayer game involving 2 teams with 4 players and i'm wondering how i will get the layer system to work in this madness. however it dawned on me that scenes for one player with the same scenes can work the other way for another player. so the real question is how are layers and scenes treated in unity networking?


-- i'm sorta new to networking, i've started about a week ago(with a half hearted attempt).
