The Ole' Collision/broadcast domain question.

[teamdoa]

Hey guys, yes, that question again! very simple one for yah.

How many collision domains and broadcast domains.

I would count it as 3 collision, 1 broadcast, but i'm not 100%

Do I count the serial off the router as a 1 broadcast and 1 collision? ..kind of confused there.

Also, if there are two routers connected via a serial cable, is that still 1 collision, and one broadcast? or does Cisco see it different?

Here is the pic.
