Free Cisco 350-501 SPCOR Actual Exam Questions - Question 2 Discussion

C and D can be ruled out since UDP and BGP don’t handle the control plane in this context. But could OTCP be a trick option? Not sure it’s ever used here.

This one’s definitely B. OMP is Cisco’s Overlay Management Protocol used for the control plane in SD-WAN, specifically between routers and vSmart controllers. A and D don’t fit here—OTCP isn’t related, and BGP isn’t the main control plane protocol in Cisco SD-WAN. C is just a transport type, not a control protocol. So B makes the most sense given how Cisco’s SD-WAN architecture works.

It’s B, OMP. That’s the protocol Cisco SD-WAN uses to exchange routing info between routers and vSmart controllers. Not sure why they threw in UDP since that's just a transport layer, not a control plane protocol. Anyone else find this question kinda confusing with those options?
