When an ExpressRoute circuit and a VPN Gateway coexist in the same VNet, which connection type takes precedence for on-premises traffic by default?
Answer: ExpressRoute takes precedence
In coexistence scenarios, ExpressRoute connections are preferred over VPN by default due to their higher AS path weight in BGP.
What does 'circuit resiliency' in ExpressRoute refer to?
Answer: Deploying redundant physical connections to avoid single points of failure
Circuit resiliency involves deploying two physical ExpressRoute connections at different peering locations to eliminate single points of failure.
Which Azure feature provides a managed ExpressRoute connection without requiring a dedicated circuit from a provider?
Answer: ExpressRoute Direct
ExpressRoute Direct allows customers to connect directly into Microsoft's global network at 10G or 100G ports without an intermediary provider.
What is the billing model for ExpressRoute data transfer by default on the Standard and Premium SKUs?
Answer: Metered — inbound free, outbound charged per GB
Standard and Premium ExpressRoute circuits use a metered billing model where inbound data is free but outbound data is charged per GB.
Which BGP community value should on-premises routers use to identify routes learned from Azure's West US region over Microsoft peering?
Answer: 12076:51006
Azure uses BGP community 12076:5XXXX values per region; West US uses 12076:51006 to tag its prefixes in Microsoft peering.
What is required to enable encryption over an ExpressRoute private peering connection?
Answer: Run a VPN Gateway over the ExpressRoute circuit using IPsec/IKE
To encrypt traffic over ExpressRoute private peering, you layer an IPsec/IKE VPN tunnel on top of the ExpressRoute circuit using a VPN Gateway.
