AWS Certified Data Engineer Associate DEA-C01 Practice Question

An AWS Data Engineer launches an Amazon EMR cluster to process log files stored in an Amazon S3 bucket. All objects are encrypted with server-side encryption using a customer managed AWS KMS key (SSE-KMS). The cluster fails immediately with AccessDenied errors when attempting to read the input files. Which action will resolve the error while adhering to the principle of least privilege?

  • Enable SSE-C on the bucket and upload new copies of the files encrypted with customer-provided keys.

  • Re-encrypt the bucket with SSE-S3 instead of SSE-KMS to eliminate KMS permissions.

  • Grant the EMR cluster's EC2 instance profile role permission to use the kms:Decrypt action on the customer managed CMK.

  • Modify the S3 bucket policy to allow s3:GetObject access for the cluster's security group.
