A multi-VPC environment connects via a transit gateway to an on-premises datacenter over a Direct Connect gateway and redundant transit VIFs. The company must get notified whenever a new route is advertised from on premises to AWS over Direct Connect. What should a network engineer implement to meet this requirement?

Transit Gateway Network Manager provides visibility into your global network, including Direct Connect connections and routes. By onboarding Network Manager to CloudWatch Logs Insights, you can analyze logs for route changes. EventBridge (formerly CloudWatch Events) can then be configured to detect specific log patterns indicating new route advertisements and trigger notifications. Enabling CloudWatch metrics on Direct Connect only tracks general connection metrics, not specific route advertisements. A Lambda function would require custom coding and periodic polling, which is less efficient and reactive than EventBridge. CloudWatch Logs on transit VIFs track VIF-level events, but Network Manager offers a more comprehensive view of route propagation across the entire transit gateway and connected networks.
