I remember that using an IGP isn't mandatory for EBGP underlay, so I think option D is definitely incorrect.

I’m uncertain about the multipath multiple-as parameter; it sounds familiar, but I can't recall if it's specifically required for EBGP underlay.

I feel like I've seen a question about route reflection and IBGP scalability before, so maybe option C is correct?

Ah, this is a good one. I've worked with BGP in IP fabrics before, so I think I can apply that knowledge to identify the correct statements. Time to put on my thinking cap.

I remember learning about BGP in the underlay, but I'm not sure I fully understand the requirements for EBGP versus IBGP. I'll need to review my notes to make sure I get this right.

Okay, let's see. I know BGP can be used as the underlay routing protocol, and I think Route Reflection is related to IBGP scalability. I'll give it my best shot.

Haha, underlay routing with BGP? That's like driving a Ferrari on gravel roads. But if you must, then B and C are the way to go. Gotta get that load-balancing and control plane scalability dialed in, am I right?

Hmm, I think A and D are the right answers. You gotta have those static routes for the EBGP peerings, and an IGP is usually a must-have. B and C are just too advanced for the underlay, in my opinion.

B is the key here. EBGP underlay needs that multipath multiple-as parameter to handle the load-balancing. C is also spot on - Route Reflection is super useful for the control plane in this scenario.

A and C are definitely correct. BGP is a great choice for the underlay, and Route Reflection can help with scalability. But D seems a bit off - I've seen EBGP underlays work just fine without an IGP.
