How can the user achieve data encryption with a snapshot?

A user is planning to schedule a backup for an EBS volume. The user wants security of the
snapshot data. How can the user achieve data encryption with a snapshot?

A.
Use encrypted EBS volumes so that the snapshot will be encrypted by AWS

B.
While creating a snapshot select the snapshot with encryption

C.
By default the snapshot is encrypted by AWS

D.
Enable server side encryption for the snapshot using S3

Explanation:
AWS EBS supports encryption of the volume. It also supports creating volumes from existing
snapshots
provided the snapshots are created from encrypted volumes. The data at rest, the I/O as well as
all the
snapshots of the encrypted EBS will also be encrypted. EBS encryption is based on the AES-256
cryptographic algorithm, which is the industry standard.
