True or False: A customer can use an Amazon CloudWatch event to trigger an AWS Lambda function that stops an Amazon EC2 instance at scheduled intervals.

• A. True
• B. False
• C. Only during peak hours
• D. Only in the US region

Answer: (A)

A customer can indeed use an Amazon CloudWatch event to trigger an AWS Lambda function that stops an Amazon EC2 instance at scheduled intervals. Amazon CloudWatch allows users to create rules that can initiate automated actions based on defined schedules or events. When you set up a CloudWatch event rule, you can specify a schedule using a cron or rate expression. Once the event is triggered, it can invoke a Lambda function. This Lambda function can include code to stop an EC2 instance. This capability is useful for automating resource management tasks, such as stopping instances during non-peak hours to save costs. This functionality is not restricted by geographical region or specific to certain hours, making it versatile for various use cases across different AWS regions and workloads. Thus, the statement is true, demonstrating the seamless integration capabilities of AWS services for operational efficiency.
