AWS Certified CloudOps Engineer Associate SOA-C03 Practice Question

A company stores sensitive financial reports in an Amazon S3 bucket. Compliance requires that every new object be encrypted at rest with a specific customer managed AWS KMS key. Any upload that does not use that key must be rejected immediately without manual review. As the CloudOps engineer, which approach meets the requirement while introducing the least operational overhead?

  • Create a bucket policy that denies s3:PutObject unless the request includes "s3:x-amz-server-side-encryption" set to "aws:kms" and "s3:x-amz-server-side-encryption-aws-kms-key-id" that matches the CMK ARN.

  • Enable default bucket encryption using SSE-KMS with the required CMK so S3 automatically encrypts all objects.

  • Turn on Amazon S3 Block Public Access for the bucket to ensure only encrypted uploads are accepted.

  • Deploy the AWS Config rule "s3-bucket-server-side-encryption-enabled" with automatic remediation to enforce SSE-KMS on the bucket.
