Which service allows you to monitor, store, and access log files from EC2 instances and other sources?

• A. Amazon CloudWatch
• B. AWS CloudTrail
• C. Amazon CloudWatch Logs
• D. AWS License Manager

Answer: (C)

Centralized log management in AWS is handled by a service built specifically for gathering and working with log data. CloudWatch Logs lets you collect logs from EC2 instances (via the CloudWatch Logs agent or the CloudWatch Agent) and from other sources, store them in central log groups, and access them for viewing, searching, and analysis. You can retain logs for as long as you need, export them to S3 for archival, and run queries or use Logs Insights to extract meaningful information. It also integrates with CloudWatch Metrics and Alarms so you can alert on patterns found in logs. AWS CloudTrail logs API activity rather than general application or OS logs, and AWS License Manager is for managing software licenses, not logging.
