Answer: Enable Amazon CloudWatch metrics on Direct Connect to track the received routes. Configure a CloudWatch alarm to send notifications when routes change.
To meet the company's requirements for receiving notifications each time a new route is advertised to AWS from on premises over Direct Connect, the network engineer should enable Amazon CloudWatch metrics on Direct Connect to track the received routes and configure a CloudWatch alarm to send notifications when routes change. This approach directly addresses the need for monitoring route advertisements over Direct Connect and leverages CloudWatch's capabilities for monitoring and alerting. Option A is the correct choice because it specifically targets the monitoring of routes received over Direct Connect, which is the core requirement. Options B, C, and D either do not directly address the requirement or involve more complex and less direct methods for achieving the same goal.
