Server-side encryption doesn't exist for Amazon S3, but only for Amazon EC2.
Server-side encryption allows to upload files using an SSL endpoint for a secure transfer.
Server-side encryption provides an encrypted virtual disk in the cloud.

Answer(s): A

Explanation:

Server-side encryption is about protecting data at rest. Server-side encryption with Amazon S3- managed encryption keys (SSE-S3) employs strong multi-factor encryption. Amazon S3 encrypts each object with a unique key. As an additional safeguard, it encrypts the key itself with a master key that it regularly rotates.

Canonical user group
Log Delivery Group
All users group

When granting account access to a group, the user can specify one of the URLs of that group instead of a canonical user ID. Amazon S3 has the following predefined groups:
. Authenticated Users group: It represents all AWS accounts.
. All Users group: Access permission to this group allows anyone to access the resource.
. Log Delivery group: WRITE permission on a bucket enables this group to write server access logs to the bucket.
