Which AWS services or features provide disaster recovery solutions for (CLF-C02)

Correct answer: B) EC2 Amazon Machine Images (AMIs) and C) Amazon Elastic Block Store (Amazon EBS) snapshots.
EC2 Amazon Machine Images (AMIs): You can create Amazon Machine Images of your EC2 instances. These AMIs serve as a backup of your EC2 instances, and you can use them to launch new instances in the event of a disaster.
Amazon Elastic Block Store (Amazon EBS) snapshots: EBS snapshots allow you to create point-in-time backups of your EBS volumes. In the case of a disaster, you can use these snapshots to restore your volumes or create new volumes.
Options A, D, and E are not directly related to disaster recovery for EC2 instances:
Option A (Reserved Instances) is related to pricing and reserved capacity rather than disaster recovery.
Option D (AWS Shield) is a managed Distributed Denial of Service (DDoS) protection service and is not specifically focused on disaster recovery for EC2 instances.
Option E (Amazon GuardDuty) is a threat detection service that continuously monitors for malicious activity but is not designed as a disaster recovery solution for EC2 instances.
