Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Amazon CloudWatch Logs
The correct answers are C and E. Amazon CloudWatch Logs can collect logs from EC2 instances and AWS services, centralizing real-time log data. Amazon S3 provides cost-effective long-term storage for archived logs. A is incorrect because Amazon Athena is a query service for data in S3, not a logging service. B is incorrect because Kinesis Data Firehose is for real-time streaming, but the question asks for a scalable and cost-effective centralized logging solution, and CloudWatch Logs plus S3 is simpler and more cost-effective. D is incorrect because EFS is a file system, not suitable for log aggregation.
