MLA-C01 Question 406
Select 3A data scientist deployed an AWS Lambda function as part of a machine learning pipeline. Recently, the function started experiencing increased latency, and the team needs to identify the root cause. Which combination of AWS tools can be used to monitor and troubleshoot this issue effectively?
- A
AWS X-Ray to trace requests and visualize the latency through the function
- B
Amazon CloudWatch Lambda Insights to monitor performance metrics such as memory usage and duration
- C
Amazon SageMaker Model Monitor to detect data drift in the pipeline
- D
Amazon CloudWatch Logs Insights to analyze and query the logs for detailed error messages
- E
AWS Trusted Advisor to identify cost optimization opportunities for the Lambda function
Show answer and explanation
Correct answers: A, B, D
Explanation
To troubleshoot latency and performance issues in an AWS Lambda function, tools like AWS X-Ray, Amazon CloudWatch Lambda Insights, and Amazon CloudWatch Logs Insights are essential. AWS X-Ray provides tracing capabilities to identify latency bottlenecks, while CloudWatch Lambda Insights offers performance metrics like memory usage and execution time. CloudWatch Logs Insights enables querying and analyzing logs for deeper insights into errors or unusual behavior. These tools collectively provide comprehensive observability and troubleshooting capabilities. Other tools, such as SageMaker Model Monitor and Trusted Advisor, are not relevant for this scenario.
- A. Correct.
AWS X-Ray is used for distributed tracing and can help pinpoint latency issues by visualizing where delays occur in the Lambda function's invocation path.
- B. Correct.
Amazon CloudWatch Lambda Insights provides performance metrics specific to Lambda functions, such as memory usage, invocation count, and duration, which are critical for identifying performance bottlenecks.
- C. Incorrect.
Amazon SageMaker Model Monitor is used for detecting data drift in machine learning models and is not relevant for troubleshooting Lambda latency or performance issues.
- D. Correct.
Amazon CloudWatch Logs Insights allows users to query and analyze the logs generated by the Lambda function, providing valuable insights into errors or anomalies.
- E. Incorrect.
AWS Trusted Advisor focuses on cost optimization, security, and best practices but does not provide tools for monitoring or troubleshooting Lambda performance issues.
