Surprised that people think it's anything other than physical connectivity!

Nah, I think it's more about emulating LAN segments.
NI

Wait, I thought it was about abstracting IP-based connectivity?

It's all about establishing physical connectivity between switches and routers.

I’m a bit confused; I thought the underlay was just for transporting Layer 2 frames, which sounds like B. But I could be mixing it up with something else!

I practiced a question similar to this, and I feel like the underlay is more about abstracting connectivity. Maybe A is the right choice?

I remember something about encapsulating traffic, but I’m not sure if that’s the main purpose of the underlay. Could it be D?

I think the underlay network is mainly about establishing physical connectivity, so I’m leaning towards option C.

I feel pretty confident that the underlay network is used to abstract the IP-based connectivity from the physical connectivity, so I'm going to go with option A.

Based on my understanding, the purpose of the Cisco SD-Access underlay network is to provide virtualization by encapsulating network traffic over IP tunnels. That sounds like option D to me.

The underlay network is responsible for establishing the physical connectivity between the switches and routers, so I'm leaning towards option C as the correct answer.

I think the purpose of the Cisco SD-Access underlay network is to abstract IP-based connectivity from physical connectivity, so that's my best guess for option A.

Hmm, I'm a bit confused on this one. I'm not sure if the underlay network is meant to emulate LAN segments or provide virtualization. I'll have to think this through more carefully.

This seems straightforward. The user can see the reports but not execute them, so the administrator needs to configure the appropriate permissions, likely at the SQL database level, to allow the user to run the reports. I'll go with option C.

Hmm, this is a tricky one. I'm not totally sure about the differences between these types of letters, but I'll try to reason through it.

Haha, the underlay is like the superhighway that the SD-Access network rides on. You can't have virtualization without that physical layer!

D definitely seems like the answer. Encapsulating network traffic over IP tunnels - that's the whole point of the underlay, right?
MA
Marcelle

Exactly, D is the answer because it establishes virtualization through IP tunnels.
WI
Wilbert

That's right. It helps provide virtualization by encapsulating network traffic.
SH

I'm pretty sure the underlay is for establishing the physical connections. I mean, how else would the SD-Access network work without that foundation?
