A university has a cage in a colocation hall that offers an Azure ExpressRoute meet-me. The university will order the cross-connect itself. No MPLS carrier is involved. Which model is this?
Select an answer to reveal the explanation.
Short Explanation
You are standing in the building, and you are the one ordering the cable. That is a colocation cross-connect to ExpressRoute. An MPLS handoff would be the carrier's job, and you already said no carrier is involved.
Full Explanation
Colocation private connectivity is the customer's own cross-connect from the customer's equipment to the cloud provider inside a shared facility. The university has the cage, the hall has the ExpressRoute meet-me, and the university orders the cable. No MPLS carrier is in the design, so this is not a provider handoff. An MPLS handoff would be the carrier extending the private WAN into ExpressRoute. An SDCI virtual circuit from a metro where they have no port does not use the cage they already occupy. Native IPsec over the hall's internet is the internet model. It never uses the ExpressRoute meet-me they are standing next to. Exam caveat: the cross-connect still needs the right ExpressRoute peering. Private peering carries virtual networks. Microsoft peering is for Microsoft public services. Operational check: the ExpressRoute circuit should show the provider status and the cross-connect up, and the university router should peer on the VLAN they ordered rather than on a VPN gateway public address.
