Exam AWS Certified Solutions Architect - Associate SAA-C02 topic 1 question 88 discussion

Ans is A: You can use AWS DataSync with your Direct Connect link to access public service endpoints or private VPC endpoints. When using VPC endpoints, data transferred between the DataSync agent and AWS services does not traverse the public internet or need public IP addresses, increasing the security of data as it is copied over the network.

A is correct. DataSync is for actual data transfer from on-premises to AWS whereas Storage Gateway is to retain access to the data that is transferred to AWS.

A is the answer

My doubt is for the term "data replication". Is it sure that we're talking of a migration and it's not a retain access scenario for wich the Storage Gateway is the solution for?

DataSYNC is for moving/transferring/migrating on-prem data to AWS. Storage Gateway is for backups.

A is correct

Q: When do I use AWS DataSync and when do I use AWS Storage Gateway? A: Use AWS DataSync to migrate existing data to Amazon S3, and subsequently use the File Gateway configuration of AWS Storage Gateway to retain access to the migrated data and for ongoing updates from your on-premises file-based applications. You can use a combination of DataSync and File Gateway to minimize your on-premises infrastructure while seamlessly connecting on-premises applications to your cloud storage. AWS DataSync enables you to automate and accelerate online data transfers to AWS Storage services. After the initial data transfer phase using AWS DataSync, File Gateway provides your on-premises applications with low latency access to the migrated data. When using DataSync with NFS shares, POSIX metadata from your source on-premises storage is preserved, and permissions from the source storage apply when accessing your files using File Gateway. ANS:A

A. Deploy an AWS DataSync agent for the on-premises environment. Configure a sync job to replicate the data and connect it with an AWS service endpoint.

Passed the exam on 19th June 2021. This question appeared in my exam. Marking it for future help.

when i see this question at the first time, I read a question they want query acceleration so I pick storage volume gateway because in Cached mode we can find data because we let data in local, so we can query faster and also it is different with file storage gateway so we can't this data in S3. So it is private. But it want acceleration with data replication so answer is A.

migration- first priority is DataSyn

https://aws.amazon.com/blogs/storage/transferring-files-from-on-premises-to-aws-and-back-without-leaving-your-vpc-using-aws-datasync/ Answer is A

Going with DataSync

Ans = A Storage GW is for hybrid synchronization. That was already established, use DataSync instead.

A rigjt

"The company is looking for a fully managed solution that will automate and accelerate the replication of data between the on-premises storage systems and AWS storage services.".......This is only for Datasync...U may also go through JB cheat sheats....

The answer is A for sure
