Exam AWS Certified DevOps Engineer - Professional DOP-C02 topic 1 question 31 discussion

Correct Answer is A. Explanation: Amazon EKS integrates with CloudWatch Logs to provide detailed logs of the state and execution of the services in the cluster. CloudWatch subscription filters can be used to route specific log events from a CloudWatch Logs group to a Lambda function. The Lambda function can then process the events and publish notifications to the appropriate Amazon SNS topic.

AWS EKS itself does not offer native S3 logging for container logs. CloudWatch Logs Insights queries cannot directly link to Amazon EventBridge events. So the answer here is A.

CloudWatch Logs subscription filtering is a feature that allows capture log data in real time and forward it to other AWS services such as Kinesis Data Firehose, Kinesis Streams, and Lambda.

A is correct: Use cloudwatch logs to collect logs from EKS. Use subcription filter to filter out logs and only send relevant logs to lambda to trigger it. B: CloudWatch Logs Insights is for data analysis. Additionally, using EventBridge events to trigger lambda incur costs C and D: Amazon S3 logging is used for monitoring actions on S3 itself, not EKS

A is right C, D are wrong , because there is not integration in EKS to send logs to s3. B is for log analysis , and aggreation

I don't have a technical reason but others dumps shows B as the Answer

A, metric filter can call Lambda.

certainly cloudwatch logs metric filter A

A. Enable Amazon CloudWatch Logs to log the EKS components. Create a CloudWatch subscription filter for each component with Lambda as the subscription feed destination. This solution involves enabling Amazon CloudWatch Logs to log the EKS components and creating a CloudWatch subscription filter for each component with AWS Lambda as the subscription feed destination. This approach will allow the Lambda function to evaluate incoming log events and publish messages to the correct Amazon SNS topic. Amazon SNS can then send email notifications to each email address based on the messages it receives from the corresponding SNS topic.

A, clear

A is the correct answer

Amazon CloudWatch Logs can log the EKS components, and subscription filters can be created for each component with AWS Lambda as the subscription feed destination. The Lambda function can evaluate incoming log events and publish messages to the appropriate Amazon SNS topic, enabling automated email notifications to be sent. Therefore, option A is the correct solution. Option C is incorrect because Amazon S3 logging is not designed for logging EKS components.

A for sure
