Two management VPLS sounds complicated, but could work.

Wait, are we really saying there's no load balancing possible? (option C)

I think option B is the way to go with 802.1D-2004.

I thought we discussed using multiple management VPLS for redundancy, so option D might be the right choice.

I feel like I read that load balancing might not be possible with redundant spoke-SDPs, but I can't recall the details.

I think option B sounds familiar, especially with 802.1D-2004. We practiced something similar in class.

I remember something about RSTP, but I'm not sure if it applies here for load balancing.

This is a great question. I feel pretty confident in my understanding of load balancing across redundant spoke-SDPs. I'll go with option A.

I'm a bit confused by the difference between RSTP and 802.1D-2004. I'll have to make sure I understand the implications of each before selecting an answer.

Okay, I think I've got this. The key is using a management VPLS to control the SDP blocking. I'll go with option D.

Hmm, I'm not sure I fully understand the concept of redundant spoke-SDPs. I'll have to review that before attempting this.

Haha, this reminds me of that time I tried to load balance my home network. Ended up just unplugging half the cables. But this VPLS thing sounds way more professional.

I was thinking C, but now that I think about it, using two VPLSes like in D makes a lot more sense. Clever solution!

Option D seems like the way to go. Using two management VPLSes with RSTP would allow for load balancing across the redundant spoke-SDPs.

That makes sense. Having two management VPLSes with RSTP blocking different SDPs for different VPLS services would help achieve load balancing.
