Haha, imagine if it used TCP for transport. That would be a mess! VXLAN is all about speed and efficiency, so it's definitely C. Good thing we're not taking the 'How to Slow Down Your Network' certification exam.

Nah, I'm pretty sure it's not 12 bytes. That's way too small for a VXLAN header. I think C is the right answer – the frame encapsulation is done using MAC-in-UDP, not TCP.

I'm confident that C) It frame encapsulation is performed by MAC-In-UDP is the characteristic of VXLAN.

VXLAN indeed uses MAC-in-UDP for frame encapsulation, making C the right answer.

No, I disagree. It's not 12 bytes. I believe C) It frame encapsulation is performed by MAC-In-UDP.

I was thinking the same thing, but I'm a little unsure about the packet header size. I thought it was 50 bytes or something, not 12 bytes. Maybe B is correct?

This is a tricky question, but I'm pretty sure the answer is A. VXLAN is designed to extend Layer 2 and Layer 3 networks over a Layer 2 underlay, which allows for more efficient use of the network infrastructure.
