Answer 1

Since the answer is already explained well for both port speed, and addressing bits, I’d like to add in a caveat.

There is a thing called burst traffic. It’s typically only used between carriers, but some businesses will opt to get it.

In essence, a cache is configured on the handoff device, so that if the traffic goes over the assigned bandwidth momentarily you will still get it, instead of it being dropped by the policers. It only works for intermittent “bursts” of traffic though, and can’t be done continually since it’s cache dependent.
