Explanation/Reference:
A switch uses a separate collision domain for each port so there are a total of 9 for each device
shown. In addition to this, the switch to switch connections (3) are a separate collision domain.
Finally, we add the switch to router connections (2) and the router to router connection (1) for a
total of 15.
