AWS Certified Data Engineer Associate DEA-C01 Practice Question

A data engineer is developing a Python AWS Lambda function that runs inside a VPC and writes transformed CSV files to an Amazon S3 bucket in the same AWS account. The company prohibits hard-coding or storing long-lived access keys. According to AWS best practices for authentication, which approach will allow the function to authenticate to S3 while complying with the policy?

  • Use an S3 Access Point, and reference its ARN when creating the Lambda function; no IAM configuration is required.

  • Add a bucket ACL granting write permission to the Lambda service's public IP addresses.

  • Store an IAM user's access key and secret key in AWS Secrets Manager and read them at runtime.

  • Configure an IAM role with S3 write permissions and assign it as the Lambda execution role.
