Exam AWS Certified Solutions Architect - Professional SAP-C02 topic 1 question 331 discussion

Exam question from Amazon's AWS Certified Solutions Architect - Professional SAP-C02
Question #: 331
Topic #: 1
[All AWS Certified Solutions Architect - Professional SAP-C02 Questions]

A company is migrating an application to the AWS Cloud. The application runs in an on-premises data center and writes thousands of images into a mounted NFS file system each night. After the company migrates the application, the company will host the application on an Amazon EC2 instance with a mounted Amazon Elastic File System (Amazon EFS) file system.

The company has established an AWS Direct Connect connection to AWS. Before the migration cutover, a solutions architect must build a process that will replicate the newly created on-premises images to the EFS file system.

What is the MOST operationally efficient way to replicate the images?

  • A. Configure a periodic process to run the aws s3 sync command from the on-premises file system to Amazon S3. Configure an AWS Lambda function to process event notifications from Amazon S3 and copy the images from Amazon S3 to the EFS file system.
  • B. Deploy an AWS Storage Gateway file gateway with an NFS mount point. Mount the file gateway file system on the on-premises server. Configure a process to periodically copy the images to the mount point.
  • C. Deploy an AWS DataSync agent to an on-premises server that has access to the NFS file system. Send data over the Direct Connect connection to an S3 bucket by using a public VIF. Configure an AWS Lambda function to process event notifications from Amazon S3 and copy the images from Amazon S3 to the EFS file system.
  • D. Deploy an AWS DataSync agent to an on-premises server that has access to the NFS file system. Send data over the Direct Connect connection to an AWS PrivateLink interface VPC endpoint for Amazon EFS by using a private VIF. Configure a DataSync scheduled task to send the images to the EFS file system every 24 hours.

Answer: D Option C is also correct but why you need s3 when DataSync moves data directly from the on-premises NFS to EFS, eliminating intermediate storage and transfer steps, reducing latency and potential bottlenecks.

Everybody sure Answer is D?? So: Amazon Elastic File System (Amazon EFS) does not offer AWS PrivateLink support directly.

why not ? See https://docs.aws.amazon.com/efs/latest/ug/efs-vpc-endpoints.html Seems to be supported

but that is not for EFS APIs, not for data flow.

Also, EFS is accessed over a mount point which can be either an IP or DNS name. Both in private network. so, DX connection is good enough for it. PrivateLink in the answer is meaningless in this case

Answer - D. Leveraging AWS PrivateLink with a private VIF ensures a private and secure connection between the on-premises environment and the Amazon EFS file system. This eliminates the need for public internet access.
