Made my own homework (broadcast and collision domains)

drew2000

Hey All,
I couldn't find enough ways to test myself on broadcast and collision domains, so I made the following Visio diagram. I'm going to post my answers in a few minutes, but I could use some help making sure I'm correct.

I separated the diagram out into three buildings to make it faster if you don't have time to correct the whole thing.

Here is the worksheet, I'll post my answers in a bit.

Thanks,
Drew
