SAP-C02 Exam - Question 330

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?

Show Answer
Correct Answer: D

The most operationally efficient way to replicate images from an on-premises NFS file system to an Amazon EFS file system is to deploy an AWS DataSync agent to an on-premises server that has access to the NFS file system. DataSync is specifically designed to automate transferring large amounts of data between on-premises storage and AWS storage services, such as EFS. By using DataSync over the AWS Direct Connect connection, you can leverage a private and high-bandwidth network link, ensuring secure and efficient data transfer. Configuring a DataSync scheduled task to send the images directly to the EFS file system every 24 hours simplifies the process and reduces the need for intermediate storage or additional processing steps. This method provides a straightforward, efficient, and reliable solution for the data replication task.

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.

D is most likely

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.

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
