Exam AWS Certified Solutions Architect - Professional SAP-C02 topic 1 question 204 discussion

Correct is C. For those voting with B, you missed the Instance configuration part. DLM will only backup the EBS volume not the instance settings also. AWS backup will backup ebs & instance settings. Option C, using AWS Backup, provides a centralized and cost-effective solution for managing backups across multiple services, including EC2 instances. By creating a scheduled daily backup plan for the EC2 instances, AWS Backup ensures regular backups are taken. The backups can be configured to be stored in a vault in the secondary Region, fulfilling the requirement of maintaining backups in a separate Region. The EC2 instance volumes and configurations can then be restored from the backup vault using AWS Backup's restore capabilities. This allows for the recovery of EC2 instances and their configurations within the required timeframe of 1 business day, with a maximum data loss of 1 day's worth.

With these RTO/RPO WE don't need to backup entire EC2 especially for cost efficiency. We Only need to maintain CF In another region as well as EBS Backups. System Manager allows you to script and execute backup and copy it to another region instead of DL

C because of this one. "The company has limited staff and needs a backup solution that optimizes operational efficiency and cost." AWS Backup really optimizes your backup solution. We backup everthing now with AWS Backup. B works too but it more complicated. The restore from AWS Backup is nearly a no brainer

C, for sure. Use AWS Backup. DLM itself does not directly support restore operations.

Correct Answer is C. Why not B, DLM can only take backup on restore. The options says using DLM restore the volumes.

Option C

Because AWS Back ups supports restore and DLM doesn't

B The explanation here fits the use-case https://aws.amazon.com/blogs/storage/automating-amazon-ebs-snapshot-and-ami-management-using-amazon-dlm/

C B would be ok, if DLM supported restore. it doesn't

I think correct is C. AWS Backup is easier and perfectly fits the scenario

B says "Use Amazon DLM to restore the EBS volumes and transfer usage to the secondary Region" - just tested it and could not find any option for DLM to restore volumes, think the snapshots are managed the usual way.

c-c-c-c-c-c-c-c-c-c

Its B!!!!!!!!!!!!!!!!

Why not A?

I prefer B to C as this sentence "The EC2 instances are persistent and store data on multiple attached Amazon Elastic Block Store (Amazon EBS) volumes", in this question, there is no database mentioned, I assume all persistent data is in EBS, so no need to backup ec2 instances, you can directly startup ec2 instance by cloudformation and load backuped ebs.

AWS Backup is more cost effective so I would chose C as well. The DLM option B, does not contemplate the back up in another region as far as I could see.

AWS Backup is a latter service which tries to simplify the challenge of administering a backup in each service individually. However AWS Lifecycle Manager originally only made EBS snapshots but has been expanded to create AMIs. I don't believe AWS Backup can trigger AMI creation.
