[All AWS Certified Solutions Architect - Professional Questions]

A company has an application that is deployed on Amazon EC2 instances behind an Application Load Balancer (ALB). The instances are part of an Auto Scaling group. The application has unpredictable workloads and frequently scales out and in. The company's development team wants to analyze application logs to find ways to improve the application's performance. However, the logs are no longer available after instances scale in.

Which solution will give the development team the ability to view the application logs after a scale-in event?

A. Enable access logs for the ALB. Store the logs in an Amazon S3 bucket.
B. Configure the EC2 instances to publish logs to Amazon CloudWatch Logs by using the unified CloudWatch agent.
C. Modify the Auto Scaling group to use a step scaling policy.
D. Instrument the application with AWS X-Ray tracing.

The right option is B 1)EC2 instance do store their logs in CloudWatch using CloudWatch agent 2)These logs are stored for indefinite time so the logs will be available even when the EC2 instance is terminated (Scaled in).

B is answer Key from question is 'development team wants to analyze application logs ' so we need EC2 logs, per B Why not A? ALB logs doesn't have logs of application itself. It has request, response etc. So ALB logs will not help here. Ref - Elastic Load Balancing provides access logs that capture detailed information about requests sent to your load balancer. Each log contains information such as the time the request was received, the client's IP address, latencies, request paths, and server responses. You can use these access logs to analyze traffic patterns and troubleshoot issues. https://docs.aws.amazon.com/elasticloadbalancing/latest/application/load-balancer-access-logs.html
