Exam AWS Certified Solutions Architect - Professional topic 1 question 437 discussion

Exam question from Amazon's AWS Certified Solutions Architect - Professional
Question #: 437
Topic #: 1
[All AWS Certified Solutions Architect - Professional Questions]

A company is finalizing the architecture for its backup solution for applications running on AWS. All of the applications run on AWS and use at least two Availability
Zones in each tier.
Company policy requires IT to durably store nightly backups for all its data in at least two locations: production and disaster recovery. The locations must be in different geographic regions. The company also needs the backup to be available to restore immediately at the production data center, and within 24 hours at the disaster recovery location. All backup processes must be fully automated.
What is the MOST cost-effective backup solution that will meet all requirements?

  • A. Back up all the data to a large Amazon EBS volume attached to the backup media server in the production region. Run automated scripts to snapshot these volumes nightly, and copy these snapshots to the disaster recovery region.
  • B. Back up all the data to Amazon S3 in the disaster recovery region. Use a lifecycle policy to move this data to Amazon Glacier in the production region immediately. Only the data is replicated; remove the data from the S3 bucket in the disaster recovery region.
  • C. Back up all the data to Amazon Glacier in the production region. Set up cross-region replication of this data to Amazon Glacier in the disaster recovery region. Set up a lifecycle policy to delete any data older than 60 days.
  • D. Back up all the data to Amazon S3 in the production region. Set up cross-region replication of this S3 bucket to another region and set up a lifecycle policy in the second region to immediately move this data to Amazon Glacier.

Support "D" answer. S3 in production for immediate recovery. Glacier for Disaster with 24 hours recovery.

A. You need an immediate restore, it's only possible with snapshots. No matter how "attractive" D looks, it doesn't fit the requirement.

Key phrase of the question "the backup to be available to restore immediately at the production data center, and within 24 hours at the disaster recovery location." and Cost effective solution. So it has to be S3 and S3 Standard (storage tire) for Production backup region. Both the condition available only in Option D. So Correct Answer is D
