AWS Certified Solutions Architect – Associate (SAA-C02) — Question 47

A company's application is running on Amazon EC2 instances in a single Region. In the event of a disaster, a solutions architect needs to ensure that the resources can also be deployed to a second Region.
Which combination of actions should the solutions architect take to accomplish this? (Choose two.)

Answer options

• A. Detach a volume on an EC2 instance and copy it to Amazon S3.
• B. Launch a new EC2 instance from an Amazon Machine Image (AMI) in a new Region.
• C. Launch a new EC2 instance in a new Region and copy a volume from Amazon S3 to the new instance.
• D. Copy an Amazon Machine Image (AMI) of an EC2 instance and specify a different Region for the destination.
• E. Copy an Amazon Elastic Block Store (Amazon EBS) volume from Amazon S3 and launch an EC2 instance in the destination Region using that EBS volume.

Correct answer: B, D

Explanation

The correct actions are B and D. Launching a new EC2 instance from an Amazon Machine Image (AMI) in a new Region ensures that the instance is set up correctly in the disaster recovery location. Copying an AMI to a different Region allows for the entire configuration of the instance to be replicated. The other options either do not directly lead to launching new instances in a different Region or involve unnecessary steps.
