A manufacturer has ExpressRoute circuits serving a plant in Chicago and another in Toronto. The two plants must exchange routes and traffic across Microsoft's network, not over the internet. Which capability should be enabled?
Show answer and explanation
Answer: A
ExpressRoute Global Reach connects ExpressRoute circuits so that on-premises sites can exchange traffic through Microsoft's backbone. It is designed for this site-to-site case between two plants. FastPath improves the data path into Azure virtual networks, BGP communities only tag routes, and gateway transit concerns virtual network peering.
Why the other options are wrong
- B. BGP communities tag or filter route advertisements. Tagging alone does not create a path between the two circuits.
- C. FastPath optimizes traffic from ExpressRoute into virtual networks. It does not connect two on-premises sites to each other.
- D. Gateway transit shares a VPN gateway between peered virtual networks. It does not link on-premises sites that use ExpressRoute circuits.
