Answer: Amazon Machine Images (AMIs), Amazon Elastic Block Store (EBS) snapshots

The correct answers are B and C. Amazon Machine Images (AMIs) are pre-configured virtual machine images that can be used to launch instances with the same configuration in the event of a disaster. AMIs are created from snapshots of the instance's root volume and any other attached EBS volumes. On the other hand, Amazon EBS snapshots are point-in-time copies of EBS volumes that can be used to create new volumes or restore existing ones. These snapshots can be used to recover data in case of an instance failure or to create a new instance in a different region or Availability Zone. Options A, D, and E do not provide disaster recovery solutions for EC2 instances.
