But wait, didn't the question mention that they're using HSRP as the FHRP? Wouldn't that mean the STP root bridge doesn't need to align with the VRRP active node? In that case, option B might be worth considering.

Haha, yeah, I hear you Naomi. These network design questions can be like a game of chess sometimes. You've got to think several moves ahead to make the right call. *sips coffee* Alright, let's keep debating this one. I'm still leaning towards option A, but I'm open to being convinced otherwise.

You know, I can already see this question causing some headaches on the exam. There are pros and cons to each option, and it really depends on how we interpret the requirements. I hope the actual exam question is a bit more straightforward!

Hmm, good point Neha. I didn't think about the HSRP aspect. In that case, maybe option B is the way to go. The access layer could be a good spot to terminate the Layer 2 interconnection.
