Well, I'm not sure your coding style is that elegant, Noelia, but I do agree that option A seems like the best choice here. It's the most future-proof, and it keeps the MTU settings in sync without potentially causing issues with other services. I'm feeling pretty confident about this one.

Haha, a cheat sheet would be nice! But seriously, I think option A is the way to go. It's the most straightforward, and if we need to change the IES MTU in the future, we can just update the VPLS service MTU. Simple and elegant, just like my coding style.

Interesting point, Odette. I hadn't considered the potential impact on other services. Option D does sound like the safest bet. Although, I have to admit, I'm a little worried about remembering all these different MTU settings. Maybe we should just ask the exam proctor to double-check our work - they probably have a cheat sheet or something.

Hmm, I'm not sure about that. Wouldn't option B potentially cause issues with other services running on the IES? Seems like it could have unintended consequences. I'm leaning more towards option D, setting the MTU of the IES network port to match the VPLS service MTU. That way, it's isolated to just that specific interface.

I agree, option A does seem like the simplest solution. Although, I wonder if that might cause issues if the IES MTU needs to be changed in the future. Maybe option B, setting the ip-mtu of the IES to match the VPLS, would be more flexible?

This is a tricky question! The MTU settings on both the VPLS and the IES need to be aligned, but it's not obvious which one should take precedence. I'm leaning towards option A, setting the service MTU of the VPLS to match the IES MTU, as that seems like the most straightforward approach.
