Q: 17
PPPoE server only works within one Ethernet broadcast domain that it is connected to. If there is a router between server and end-user host, it will not be able to create PPPoE tunnel to that PPPoE server.

That's false, PPPoE server can work across broadcast domains if you set up a relay.
Probably False, since PPPoE relay lets it work across routers. The question makes B sound tempting but A is right for Mikrotik.
I agree with A here. PPPoE can cross routers if PPPoE relay is configured, so it’s not limited to just one broadcast domain. Pretty sure that’s standard MikroTik behavior. If anyone had a scenario where it didn’t work, let me know.
False.
Yeah that's what I thought too, routers can block broadcast domains but if you use PPPoE relay, it works across them. So False.
False tbh. PPPoE can run over routed networks if you bridge the broadcast domains with something like PPPoE relay. Clean wording in the question made it easy to spot.
