Topic 1 Question 221
A company is migrating its on-premises network from its data center in Virginia to its data center in New York. The AWS Direct Connect connections for the Virginia and New York data center locations are both associated to the us-east-1 Region. The company needs to migrate a private VIF on an existing Direct Connect hosted connection from Virginia to New York. The company's on-premises network uses the connection to access VPCs through a Direct Connect gateway in us-east-1.
The company has already requested a new Direct Connect hosted connection from the new data center to the New York Direct Connect location.
Which solution will meet these requirements with the LEAST downtime?
Create a new private VIF on the new Direct Connect hosted connection. Create a new Direct Connect gateway and attach the gateway to the new private VIF. Configure BGP routing on the new private VIF as a backup route. Perform the switchover during a maintenance window by shutting down BGP on the existing private VIF. Decommission the existing Direct Connect connection.

During a maintenance window, migrate the existing private VIF to the new Direct Connect hosted connection. Attach the existing private VIF to the existing Direct Connect gateway. Decommission the existing Direct Connect connection.
During a maintenance window, delete the existing private VIF and create a new private VIF to the new Direct Connect hosted connection. Attach the new private VIF to the existing Direct Connect gateway. Decommission the existing Direct Connect hosted connection.

Since we are setting a new connection as a backup route before we disable the old connection, it provide a lowest downtime.
👍 3ArunRav2024/11/18 least downtime with backup. So the answer is B

Option A:Creating a new Direct Connect gateway introduces unnecessary complexity and does not align with the requirement to use the existing gateway. Option C:Migrating the existing private VIF directly to the new connection during the maintenance window would cause downtime because the VIF would need to be detached and reattached. Option D:Deleting the existing private VIF before creating a new one would lead to downtime, as there would be no active connection during the transition.
