Your company previously configured a heavily used, dynamically routed VPN connection
between your on-premises data center and AWS.
You recently provisioned a DirectConnect connection and would like to start using this new
connection. After configuring DirectConnect settings in the AWS Console, which of the following
options will provide the most seamless transition for your users?
A.
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.
B.
Delete your existing VPN connection to avoid routing loops, configure your DirectConnect router
with the appropriate settings, and verify network traffic is leveraging DirectConnect.
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 with a higher BGP priority than your VPN router, verify
network traffic is leveraging DirectConnect, and then delete your existing VPN connection.
Explanation:
Direct Connect takes priority over Dynamically configured VPN connections.
Why I should update my VPC route table?
I think D is correct! If update route tables and then configure the router, the traffic maybe affected! So C is wrong!!!
As per the explanation they provided D is the answer.
Answer C.
A and D are wrong because they both talk about setting priority and we know we don’t need to do that.
B is incorrect because you don’t need to turn off the VPN connection to avoid routing loops.
That leaves C as the best answer.
