Your organization wants to deploy HA VPN over Cloud Interconnect to ensure encryption-in-transit over the Cloud Interconnect connections. You have created a Cloud Router and two encrypted VLAN attachments that have a 5 Gbps capacity and a BGP configuration. The BGP sessions are operational. You need to complete the deployment of the HA VPN over Cloud Interconnect. What should you do?

A. Create an HA VPN gateway and associate the gateway with your two encrypted VLAN attachments. Configure the HA VPN Cloud Router, peer VPN gateway resources, and HA VPN tunnels. Use the same encrypted Cloud Router used for the Cloud Interconnect tier.
B. Enable MACsec on Partner Interconnect.
C. Enable MACsec for Cloud Interconnect on the VLAN attachments.
D. Create an HA VPN gateway and associate the gateway with your two encrypted VLAN attachments. Create a new dedicated HA VPN Cloud Router, peer VPN gateway resources, and HA VPN tunnels.

A is incorrect, here's why: The Cloud Router for Cloud Interconnect is dedicated to exchanging prefixes between VLAN attachments for the Interconnect tier, while the Cloud Router for HA VPN handles the exchange of prefixes between your VPC network and your on-premises network.

Selected Answer: A

The existing Cloud Router can handle both BGP sessions. Creating a new one adds complexity and doesn't directly solve the main configuration steps needed for the VPN tunnels and gateway.

Selected Answer: A

A A more accurate step 1 might be "Create an HA VPN gateway in the same region and VPC as the Cloud Interconnect VLAN attachments." But that option isn't available. Given the options, Option A is the best fit for the required steps to complete the HA VPN over Cloud Interconnect deployment, despite the minor inaccuracy in how the gateway is described as being "associated" with VLAN attachments. The other options are either incorrect technologies or similarly flawed in their descriptions.
