A company wants to improve visibility into its AWS environment. The AWS environment consists of multiple VPCs that are connected to a transit gateway.

What should a network engineer do to meet these requirements?

A. Enable Amazon CloudWatch metrics on Direct Connect to track the received routes. Configure a CloudWatch alarm to send notifications when routes change.
B. Onboard Transit Gateway Network Manager to Amazon CloudWatch Logs Insights. Use Amazon EventBridge (Amazon CloudWatch Events) to send notifications when routes change.
C. Configure an AWS Lambda function to periodically check the routes on the Direct Connect gateway and to send notifications when routes change.

B - correct Transit Gateway Network Manager provides a centralized view of global networks built on AWS Transit Gateway. It also provides the capability to monitor the routing tables associated with the transit gateway, and then forward routing information to CloudWatch Logs Insights. Once in CloudWatch Logs Insights, you can use EventBridge rules to trigger notifications based on routing changes. This will allow the company to receive notifications each time a new route is advertised to AWS from on-premises over Direct Connect, which meets the requirements. The other options either do not provide the necessary functionality or would not be the most efficient solution for this scenario.

Selected Answer: B

it is B - tested and confirmed. the problem is - if a static route exists and the same prefix gets advertised - it will not be flagged and no Event will trigger.
