Question

A company connects its on-premises data center to a VPC using a single 1 Gbps Direct Connect dedicated connection through a private virtual interface (VIF) to a virtual private gateway. During a recent Direct Connect maintenance event, all connectivity between the data center and the VPC was lost, causing an application outage. The CloudOps team must add a resilient backup path that automatically carries traffic if the Direct Connect connection fails, while keeping ongoing costs as low as possible. Which solution meets these requirements?

Accepted Answer

Provision a Site-to-Site VPN connection to the same virtual private gateway as a backup, relying on BGP so traffic fails over to the VPN when the Direct Connect connection is unavailable.

Answer

Order a second 1 Gbps Direct Connect dedicated connection at a different location and configure both private VIFs to the same virtual private gateway.

Answer

Create a Direct Connect gateway and attach a transit gateway so the existing connection automatically reroutes traffic during maintenance.

Answer

Enable a static route in the VPC route table pointing to the on-premises CIDR through the virtual private gateway as a standby path.
