Amazon Web Services AWS Certified Developer - Associate DVA-C02 Question # 162 Topic 17 Discussion

DVA-C02 Exam Topic 17 Question 162 Discussion:
Question #: 162
Topic #: 17

A company runs an application that currently uploads content to an unencrypted Amazon S3 bucket. The S3 bucket contains millions of objects that total more than 2 TB in size. A new company policy requires all data to be encrypted. The company creates an AWS KMS key to use for encryption.

Which solution will meet this requirement MOST cost-effectively?
A.

Modify the properties of the S3 bucket. Enable default encryption, select SSE-KMS, and specify the Amazon Resource Name (ARN) of the provided KMS key.

B.

Create an S3 bucket policy that denies any PutObject requests that do not include the x-amz-server-side-encryption header that specifies the Amazon Resource Name (ARN) of the provided KMS key. Apply this policy to the bucket.

C.

Configure an Amazon S3 Batch Operations job. Choose the source bucket that contains the unencrypted objects. Select the COPY operation. Specify the source bucket as the destination. In the copy operation parameters, specify the Amazon Resource Name (ARN) of the provided KMS key.

D.

Develop a script by using the AWS SDK. Configure the script to iterate through all objects in the bucket and download each object locally. Ensure that the script then re-uploads each object to the same object key name and specifies server-side encryption with the KMS key during the re-upload.
