Question 8 of 65 | ← Chapter 6

Q373. 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? (Select 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 the on-premises location and AWS ✓

Correct Answer: B. Create an Amazon Elastic File System (Amazon EFS) file system, E. Install an AWS DataSync agent in the on-premises data center. Use a DataSync task between the the on-premises location and AWS

Explanation

The most cost-effective combination of steps to migrate an on-premises data center to AWS while maintaining uninterrupted services and allowing multiple resources to access the data using the NFS protocol would be:B. Create an Amazon Elastic File System (Amazon EFS) file system: Amazon EFS provides a scalable and fully managed NFS file system that can be easily mounted by multiple AWS resources. You can create an EFS file system in AWS and then use the AWS DataSync agent to transfer the data from the on-premises storage server the EFS file system.E. Install an AWS DataSync agent in the-premises data center. Use a DataSync task between the- premises location and AWS: AWS DataSync is a service that simplifies and accelerates data transfer between on-premises storage systems and AWS storage services. By installing the DataSync agent in the- premises data center, you can create a DataSync task to efficiently transfer the data from the on-premises storage server to the EFS file system in AWS.By combining Amazon EFS and AWS DataSync, you can migrate the data without interruption to existing services, ensure multiple resources can access the data using the NFS protocol, and achieve cost- effectiveness through the use of managed services and efficient data transfer mechanisms.
