Exam question from Amazon's AWS Certified Solutions Architect - Associate SAA-C03
Question #: 617
Topic #: 1
[All AWS Certified Solutions Architect - Associate SAA-C03 Questions]

A company wants to migrate an on-premises data center to AWS. The data center hosts a storage server that stores data in an NFS-based file system. The storage server holds 200 GB of data. The company needs to migrate the data without interruption to existing services. Multiple resources in AWS must be able to access the data by using the NFS protocol.

Which combination of steps will meet these requirements MOST cost-effectively? (Choose two.)

  • A. Create an Amazon FSx for Lustre file system.
  • B. Create an Amazon Elastic File System (Amazon EFS) file system.
  • C. Create an Amazon S3 bucket to receive the data.
  • D. Manually use an operating system copy command to push the data into the AWS destination.
  • E. Install an AWS DataSync agent in the on-premises data center. Use a DataSync task between the on-premises location and AWS.

Selected Answer: BE
Amazon EFS provides a scalable, high performance NFS file system that can be accessed from multiple resources in AWS. AWS DataSync can perform the migration from the on-prem NFS server to EFS without interruption to existing services. This avoids having to manually move the data which could cause downtime. DataSync incrementally syncs changed data. EFS and DataSync together provide a cost-optimized approach compared to using S3 or FSx, while still meeting the requirements. Manually copying 200 GB of data to AWS would be slow and risky compared to using DataSync.
