AWS Certified Cloud Practitioner

Explanation

Amazon CloudWatch is the correct answer because it is AWS's monitoring and observability service designed specifically for collecting and tracking metrics, logs, and events from AWS resources and applications.

Why CloudWatch is correct:

• Metrics Collection: CloudWatch collects monitoring and operational data in the form of logs, metrics, and events
• AWS Service Integration: It automatically provides metrics for many AWS services like EC2, S3, RDS, Lambda, etc.
• Real-time Monitoring: Allows you to monitor AWS resources and applications in real-time
• Custom Metrics: You can also publish your own custom metrics

Why other options are incorrect:

• A. Amazon CloudFront: This is a content delivery network (CDN) service, not a monitoring service
• B. Amazon CloudSearch: This is a managed search service, not related to metrics collection
• D. Amazon Machine Learning (Amazon ML): This is a machine learning service for building ML models, not for metrics monitoring

CloudWatch provides a unified view of AWS resource utilization, application performance, and operational health, making it essential for monitoring AWS environments.
