A company has two on-premises data centers and an Azure subscription. They need to connect each data center to Azure with a private, high-bandwidth, and reliable connection. They also want a low-cost backup connection for each data center in case the primary connection fails. Which combination of connectivity options should they recommend?
Trap 1: B
Using site-to-site VPNs as primary connections may not provide the required high bandwidth and reliability. ExpressRoute circuits as backup would be expensive and not commonly used as a backup due to cost.
Trap 2: C
A single Azure VPN Gateway with active-passive configuration is not designed for primary connections from two data centers; it also does not provide the low latency or reliability of ExpressRoute.
Trap 3: D
Sharing a single ExpressRoute circuit and a single VPN connection between two data centers is not practical as each data center needs its own connection to Azure.
- A
A
Deploy an ExpressRoute circuit for each data center as the primary connection, and a site-to-site VPN as the backup connection for each. This provides high bandwidth and reliability with a cost-effective failover.
