Question

A company uses AWS Cloud WAN as a primary connectivity solution to establish communication between VPCs in a multi-account and multi-Region environment. The company has created an attachment policy statement in the AWS Cloud WAN core network policy. The attachment policy requires acceptance for new VPC attachments, regardless of the segment that the new VPC attachment needs to be associated with. The company wants to automate acceptance for new VPC attachments based on specific conditions. The company creates an AWS Lambda function to check for the specific conditions. A network engineer must integrate the Lambda function with the company’s existing architecture. Which solution will meet these requirements in the MOST cost-effective way?

Accepted Answer

Correct answer: B. The correct answer is B. Option B: Create an Amazon EventBridge rule to match AWS Network Manager events for the VPC attachments. Configure the EventBridge rule to invoke the Lambda function when the rule matches. AWS Lambda runs code without provisioning servers and scales automatically, which minimizes operational overhead. Amazon EventBridge routes events between services with rules, enabling event-driven, decoupled architectures. AWS Config tracks resource configuration changes and evaluates compliance. This option delivers the requirement at the lowest cost.
