A company wants to improve visibility into its AWS environment. The AWS environment consists of multiple VPCs that are connected to a transit gateway. The transit gateway connects to an on-premises data center through an AWS Direct Connect gateway and a pair of redundant Direct Connect connections that use transit VIFs. The company must receive notification each time a new route is advertised to AWS from on premises over Direct Connect.
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.
D. Enable Amazon CloudWatch Logs on the transit VIFs to track the received routes. Create a metric filter Set an alarm on the filter to send notifications when routes change.
