Exam AWS Certified Advanced Networking - Specialty ANS-C01 topic 1 question 69 discussion

Exam question from Amazon's AWS Certified Advanced Networking - Specialty ANS-C01
Question #: 69
Topic #: 1
[All AWS Certified Advanced Networking - Specialty ANS-C01 Questions]

A company has deployed a web application on AWS. The web application uses an Application Load Balancer (ALB) across multiple Availability Zones. The targets of the ALB are AWS Lambda functions. The web application also uses Amazon CloudWatch metrics for monitoring.
Users report that parts of the web application are not loading properly. A network engineer needs to troubleshoot the problem. The network engineer enables access logging for the ALB.
What should the network engineer do next to determine which errors the ALB is receiving?

  • A. Send the logs to Amazon CloudWatch Logs. Review the ALB logs in CloudWatch Insights to determine which error messages the ALB is receiving.
  • B. Configure the Amazon S3 bucket destination. Use Amazon Athena to determine which error messages the ALB is receiving.
  • C. Configure the Amazon S3 bucket destination. After Amazon CloudWatch Logs pulls the ALB logs from the S3 bucket automatically, review the logs in CloudWatch Logs to determine which error messages the ALB is receiving.
  • D. Send the logs to Amazon CloudWatch Logs. Use the Amazon Athena CloudWatch Connector to determine which error messages the ALB is receiving.

ELB doesn't have direct integration with CloudWatch. ELB can drop the logs in S3 bucket and Athena can be used to analyse the logs. Ans - B

Option B) is correct Access logs is an optional feature of Elastic Load Balancing that is disabled by default. After you enable access logs for your load balancer, Elastic Load Balancing captures the logs and stores them in the Amazon S3 bucket that you specify as compressed files. You can disable access logs at any time. https://docs.aws.amazon.com/elasticloadbalancing/latest/application/load-balancer-access-logs.html

Selected Answer: B
This solution meets the requirements of the network engineer as follows: Configuring an S3 bucket destination for log data allows the network engineer to capture and analyze log data from the ELB. Using Amazon Athena to query the logs enables the network engineer to quickly identify error messages and troubleshoot issues.

ELB can only send access logs to S3; from there use Athena for querying. B is correct.

https://docs.aws.amazon.com/AmazonCloudWatch/latest/logs/AnalyzingLogData.html This is because CloudWatch Insights provides a powerful query language that can help you quickly identify patterns and troubleshoot issues in your log data.

B is correct. ALB access logs can only be stored in an S3 bucket and cannot be sent directly to CloudWatch Logs. Therefore, option A is not a valid solution for determining which error messages the ALB is receiving
