I’m leaning towards B) 5004 too. It’s logical.

C) 5008 has to be the answer. Encapsulation needs space!

A) 5000 is safe, but I’m not sure it’s optimal.

I agree with B) 5004. It accounts for the extra tags.

D) 5018? That’s way too high, isn’t it?

C) 5008 seems right. More room for encapsulation.

I feel like A) 5000 is too straightforward.

I think it should be B) 5004. It makes sense with the overhead.

Wait, why isn't it just 5000? That seems odd.

Definitely 5004, that's standard for Q-in-Q.

The MTU on the access port should be 5004.

I feel like I might be mixing up the values. Was it 5004 or 5018? I need to double-check the overhead calculations for Q-in-Q.

I practiced a similar question where we had to calculate the MTU for encapsulation, and I think it was always about adding the overhead. Could it be 5008?

I remember something about adding the VLAN tags for Q-in-Q, which might mean we need to add 4 bytes to the MTU. So, maybe 5004?

I think the MTU on the access port should be larger than the service MTU, but I'm not sure by how much.
