9126? That seems high, are you sure about that?

9100 seems too low for access ports, right?

Wait, isn't it 9104? I thought that was the standard.

The recommended MTU is usually 9122 for dot1q.

I thought the MTU needed to be 9122 to account for the extra bytes, but I could be mixing it up with another topic.

I feel like the answer might be 9104, but I can't remember if that's the right adjustment for the overhead.

I think we practiced a question like this, and I recall that the MTU should be a bit higher than 9100 because of the encapsulation.

I remember that the MTU for dot1q adds some overhead, but I'm not sure how much exactly.

I'm pretty confident this is a 17% question. The long form is only sent to a sample of households, not the whole population.

Hmm, I'm a little unsure about this one. I know audits can be requested by different parties, but I'm not totally clear on the specific differences between the options given. I'll have to think this through.
