Which AWS services or features provide disaster recovery solutions for Amazon EC2 instances?
(Choose two.)
2 Reserved Instances
EC2 Amazon Machine Images (AMIs)
Amazon Elastic Block Store (Amazon EBS) snapshots
AWS Shield
Amazon GuardDuty
Explanations:
Reserved Instances are primarily a billing feature for EC2 instances and do not provide disaster recovery solutions.
Amazon Machine Images (AMIs) allow you to create backups of your EC2 instances, enabling quick recovery and launching of instances in case of failure.
Amazon EBS snapshots provide point-in-time backups of EBS volumes, facilitating disaster recovery by allowing you to restore volumes from these snapshots.
AWS Shield is a security service that protects against DDoS attacks; it does not offer disaster recovery solutions.
Amazon GuardDuty is a threat detection service that monitors for malicious activity and does not contribute to disaster recovery for EC2 instances.
I judge that the answer is:
EC2 Amazon Machine Images (AMIs)
