You are designing the hybrid connectivity between an on-premises data center and Azure.
The business requires a dedicated, private connection that does not traverse the public internet. The connection must support up to 10 Gbps throughput. Additionally, if this primary connection fails, there must be an automatic backup connection, though the backup connection can traverse the internet and operate at a lower bandwidth.
Which THREE components should you include in your design? (Select THREE)

Answer options:
A.
Azure ExpressRoute circuit
B.
ExpressRoute Gateway
C.
VPN Gateway
D.
Azure Front Door
E.
Azure Private Link
How to approach this question
Identify the service for private high-speed connectivity, its required gateway, and the service for internet-based backup connectivity.
Full Answer
Azure ExpressRoute circuit, ExpressRoute Gateway, VPN Gateway
To meet the requirements, you must use Azure ExpressRoute. ExpressRoute provides a private, dedicated connection up to 10 Gbps (or 100 Gbps with ExpressRoute Direct) that bypasses the public internet. To terminate this in Azure, you need an ExpressRoute Gateway. For the backup connection, the standard architectural pattern is to deploy a Site-to-Site VPN using an Azure VPN Gateway. If the ExpressRoute circuit fails, BGP routing automatically fails over to the VPN Gateway.
Common mistakes
Forgetting that ExpressRoute requires its own specific gateway (ExpressRoute Gateway) in addition to the circuit itself.
