Answers

D.
Put thp metadata in thp S3 hurkpf itself.
Answers
D.
Put thp metadata in thp S3 hurkpf itself.
Suggested answer: C

Explanation:

Option A ,B and D are all invalid because the metadata will not be encrypted in any case and this is a key requirement from the question. One key thing to note is that when the S3 bucket objects are encrypted, the meta data is not encrypted. So the best option is to use an encrypted DynamoDB table Important All GET and PUT requests for an object protected by AWS KMS will fail if they are not made via SSL or by using SigV4. SSE-KMS encrypts only the object data. Any object metadata is not encrypted. For more information on using KMS encryption for S3, please refer to below URL: 1 https://docs.aws.amazon.com/AmazonS3/latest/dev/UsingKMSEncryption.htmlThe correct answer is: Put the metadata in a DynamoDB table and ensure the table is encryptedduring creation time.
