Explanation

Option C is correct because CloudWatch alarms support direct Lambda invocation as an alarm action, and Lambda can execute custom code to call the internal ticketing tool's API - making it the only option that actually creates a ticket in a proprietary system without additional components.

Option A (SNS) is wrong because SNS only sends notifications (email, SMS, HTTP webhooks) - it has no built-in mechanism to create tickets in a custom internal tool. SNS alone stops short of the required action.

Option B (SQS) is wrong on two levels: CloudWatch alarms cannot directly target SQS queues (they natively support SNS and Lambda), and even if they could, SQS only queues messages - it doesn't execute any logic to create a ticket.

Option D (EventBridge) is wrong because the VPN tunnel is already being monitored by the existing CloudWatch alarm; adding a redundant EventBridge rule monitoring the same resource is unnecessary complexity, and the option doesn't specify how a ticket actually gets created.

Memory tip: Whenever an exam question involves integrating an AWS event with a custom internal system or proprietary tool, Lambda is almost always the answer - it's the universal adapter that bridges AWS events to any external API or business logic.
