Hmm, I'm not too familiar with ExpressRoute, but based on the name, I'm guessing it's some kind of express or fast connection. So my money's on Layer 7, the application layer.

Ah, I remember learning about ExpressRoute in my networking class. I think it's a Layer 2 service because it provides a direct, private connection to Microsoft's cloud infrastructure.

I'm pretty sure ExpressRoute is a direct connection to Microsoft's network, so it has to be operating at Layer 2 or 3. I'm leaning towards Layer 2 since it's a dedicated connection.

Hmm, this is a tricky one. ExpressRoute is a Microsoft service, so I'm guessing it operates at a higher layer, probably Layer 3 or 7.
