Answer: Create an Amazon Simple Notification Service (Amazon SNS) topic for the CloudWatch alarm. Subscribe the ticketing tool's endpoint to the SNS topic.
CloudWatch alarm on VPN tunnel state can notify SNS topic directly. If the ticketing tool supports email or has SNS integration (webhook via Lambda but for least, SNS subscribe the endpoint if supported or use Lambda but option A is simple if tool accepts SNS). But for ticket creation, often Lambda, but given options, SNS is straightforward for notification.

A company has internal hybrid applications that have resources in the AWS Cloud and on premises. Users report that the applications sometimes are not available. The company has configured an Amazon CloudWatch alarm to monitor the tunnel status of its AWS Site-to-Site VPN connection. A SysOps administrator must implement a solution that creates a high-priority ticket in an internal ticketing tool when the VPN tunnel is down. Which solution will meet this requirement?
A
Create an Amazon Simple Notification Service (Amazon SNS) topic for the CloudWatch alarm. Subscribe the ticketing tool's endpoint to the SNS topic.
B
Create an Amazon Simple Queue Service (Amazon SQS) queue as the target for the CloudWatch alarm. Configure the queue to transform messages into tickets and to post the tickets to the ticketing tool's endpoint.
C
Create an AWS Lambda function. Configure the CloudWatch alarm to directly invoke the Lambda function to create individual tickets in the ticketing tool.
D
Create an Amazon EventBridge rule that monitors the VPN tunnel directly. Configure the ticketing tool's endpoint as the target of the rule.
