• C. Update your VPC route tables to point to the DirectConnect connection configure your DirectConnect router with the appropriate settings verify network traffic is leveraging DirectConnect and then delete the VPN connection.
• D. Configure your DirectConnect router, update your VPC route tables to point to the DirectConnect connection, configure your VPN connection with a higher BGP priority, and verify network traffic is leveraging the DirectConnect connection.

Correct answer: B

Explanation

Option B is correct because by configuring the DirectConnect router with a higher BGP priority, it ensures that traffic is routed through DirectConnect first, allowing for a seamless transition. The other options either involve deleting the VPN connection too early, which could cause disruptions, or do not prioritize the DirectConnect connection effectively, leading to potential routing conflicts.
