AWS Certified Developer Associate DVA-C02 Practice Question

Amazon CloudWatch is the correct answer because it is the primary AWS service for monitoring resources like EC2 instances. It allows you to collect and track metrics such as CPU utilization, set alarms that trigger notifications when thresholds are breached, and centralize log collection with CloudWatch Logs. This provides a comprehensive, integrated solution for observability and operational health. Amazon Kinesis is designed for real-time processing of streaming data, not for general resource monitoring and alarming. AWS CloudTrail is a service that logs API calls for governance and auditing, but it does not track performance metrics like CPU utilization. Amazon S3 is an object storage service and can be used as a destination for logs, but it lacks the native, real-time monitoring and alerting capabilities that CloudWatch provides.
