AWS Certified Cloud Practitioner — Question 611

A company needs to run code in response to an event notification that occurs when objects are uploaded to an Amazon S3 bucket.

Which AWS service will integrate directly with the event notification?

Answer options

• A. AWS Lambda
• B. Amazon EC2
• C. Amazon Elastic Container Registry (Amazon ECR)
• D. AWS Elastic Beanstalk

Correct answer: A

Explanation

AWS Lambda integrates directly with Amazon S3 event notifications, allowing serverless functions to run automatically when objects are uploaded. Amazon EC2, Amazon ECR, and AWS Elastic Beanstalk cannot be triggered directly by S3 events without additional integration components.
