Not sure about that firewall option, seems risky.

A separate VRF for guests makes total sense!

Wait, can guests really be on the same network as corporate teams?

I think option C is the best fit here!

MPLS Layer 3 VPN is a solid choice for this scenario.

I’m leaning towards option D because it mentions separate VRFs for each branch, but I’m not entirely sure how that would handle guest traffic effectively.

I practiced a similar question where we had to consider guest access, and I think a firewall in the data center could be crucial for security.

I think option C makes sense since it allows for separate VRFs, but I’m a bit confused about how the firewall would fit into the solution.

I remember studying about MPLS and how it can separate traffic using VRFs, but I'm not sure if it's the best choice for guest access.

I'm not too confident on this one. The firewall option seems like it could work, but I'm not sure if that's the most efficient solution given the requirements. I'll need to review the MPLS VPN concepts again.

Hmm, I'm a bit unsure about this one. The different VRF options are throwing me off. I'll need to re-read the question and think through the pros and cons of each approach.

This seems like a straightforward WAN design question. I'll need to carefully consider the requirements around guest access and the location of the internet gateway.

Okay, I think I've got this. The key is separating the guest traffic from the corporate traffic, and using a MPLS Layer 3 VPN with a separate VRF for guests is the way to go.

I bet the engineer who wrote this question is sitting back, laughing at all the poor souls trying to figure it out. 'Separate VRFs? Haha, good luck with that!

Ah, the age-old dilemma of corporate and guest networks. I say we just put up a big 'No Guests Allowed' sign and call it a day. But seriously, I agree with C. Gotta keep those pesky guests away from the good stuff.

Option D sounds like overkill. Do we really need a separate VRF for each branch? I think C is the way to go - keep it simple, but still keep the traffic separated.

I don't know, man. Putting the firewall in the data center seems like a lot of extra work. Why not just use a different service provider for the guests? That's the simple solution.

I'm not sure, but option D could also work well for providing connectivity to branch locations.

Option C looks good to me. Separating corporate and guest traffic is a must, and MPLS VPNs are a solid choice for WAN connectivity.

That could work too, but MPLS Layer 3 VPNs provide a more scalable and flexible solution for connecting branch locations.

But wouldn't it be more cost-effective to have a firewall in the data center to filter guest traffic?
