A user is trying to launch an EBS backed EC2 instance under free usage. The user wants to achieve
encryption of the EBS volume. How can the user encrypt the data at rest?

A.
Use AWS EBS encryption to encrypt the data at rest

B.
The user cannot use EBS encryption and has to encrypt the data manually or using a third party tool

C.
The user has to select the encryption enabled flag while launching the EC2 instance

D.
Encryption of volume is not available as a part of the free usage tier

Explanation:
AWS EBS supports encryption of the volume while creating new volumes. It supports encryption of the data at
rest, the I/O as well as all the snapshots of the EBS volume. The EBS supports encryption for the selected
instance type and the newer generation instances, such as m3, c3, cr1, r3, g2. It is not supported with a micro
instance.
