You have an S3 bucket defined in AWS. You want to ensure that you encrypt the data before sending it across the wire to the S3 bucket. What is the best way to achieve this?

Answer options:

A.Enable server-side encryption for the S3 bucket. This request will ensure that the data is encrypted before it is saved in the bucket.
B.Encrypt the data using the KMS key SSE-S3 before sending the data to S3.
C.Use a Lambda function to encrypt the data in transit.
D.Enable client-side encryption for the S3 bucket.

Answer – D
Option A is incorrect because server-side encryption does not encrypt the data before the data is saved in S3.
Option B is incorrect because the SSE-S3 key is for server-side encryption and cannot encrypt the data before the data is sent to S3.
Option C is incorrect because you have to maintain a Lambda function, and the function should encrypt the data at rest, not in transit.
Option D is CORRECT because client-side encryption can encrypt the data before sending it to Amazon S3.
