A customer is looking for a reliable and cost-effective way to back up workload data running in VMware Cloud on AWS. What is the most appropriate solution?
A.
Deploy a virtual machine AWS EC2 and mount AWS Elastic File Storage (EFS) to this virtual machine; configure this virtual machine as the backup target for image-based backups in VMware vSphere Data Protection.
B.
Deploy a virtual machine in VMware Cloud on AWS and mount AWS Elastic File Storage (EFS) to this virtual machine; configure this virtual machine as the backup target for image-based backups in VMware vSphere Data Protection.
C.
Create an S3 bucket in another availability zone and validate that the customers preferred backup solution is supported for VMware Cloud on AWS; otherwise guide the customer to choose another backup solution.
D.
Create an S3 bucket in the same availability zone and validate that the customers preferred backup solution is supported for VMware Cloud on AWS; otherwise guide the customer to choose another backup solution.
You can only select the region for S3. So the premise of c and d are incorrect. If region was used instead of AZ then it is the most reliable and cost-effective.
Im going to say D. The word "cost effective" is key. So it needs to be in the same AZ because everytime traffic leaves the AZ for backups or restores there will be charges.
I would choose B. S3 should be used as a secondary backup/archive location. Veeam cannot directly backup to S3. The backup will first be send to a performance tier and then send to S3.
Why not D? Traffic within AZ incurred additional costs. C is a reasonable solution: it provides a backup/restore and also a disaster recovery. For a backup/restore solution (restore a corrupted VM) a backup solution within the same AZ could be enough and cheaper.
Update:
I guess Answer C. should be correct. Session 3 Slide 40 suggests that you may use a Backup Solution like Veeam and use S3 Storage as Destination for your Backups
B. is possible, but EFS is not a cost-effective Way for Backups, as it is intend to be used as primary Storage. VDP is EOA/EOGS <=vSphere 6.5
D. may also be correct. Staying in the same AZ is more cost effective but less available. S3 One Zone-IA is 20% cheaper but the data may be inaccessible or lost if the AZ is down.
Creating an S3 Bucket in an AZ makes the Question confusing, as S3 Buckets are designed to be independent of AZs and created with a specific storage Class and not AZs.

Incomplete information in the question? I'd have thought S3 in a different AZ would be the most cost-effective and reliable way. A VM is a single point of failure, so definitely not as reliable as S3. If I get this question, I'll be going with C.
