AWS Certified SAP on AWS – Specialty (PAS-C01) — Question 56
A company is moving to the AWS Cloud gradually. The company has multiple SAP landscapes on VMware. The company already has sandbox, development, and QA systems on AWS. The company’s production system is still running on premises. The company has 2 months to cut over the entire landscape to the AWS Cloud.
The company has adopted a hybrid architecture for the next 2 months and needs to synchronize its shared file systems between the landscapes. These shared file systems include /trans directory mounts, /software directory mounts, and third-party integration mounts. In the on-premises landscape, the company has NFS mounts between the servers. On the AWS infrastructure side, the company is using Amazon Elastic File System (Amazon EFS) to share the common files.
An SAP solutions architect needs to design a solution to schedule transfer of these shared files bidirectionally four times each day. The data transfer must be encrypted.
Which solution will meet these requirements?
Answer options
- A. Write an rsync script. Schedule the script through cron for four times each day in the on-premises VMware servers to transfer the data from on premises to AWS.
- B. Install an AWS DataSync agent on the on-premises VMware platform. Use the DataSync endpoint to synchronize between the on-premises NFS server and Amazon EFS on AWS.
- C. Order an AWS Snowcone device. Use the Snowcone device to transfer data between the on-premises servers and AWS.
- D. Set up a separate AWS Direct Connect connection for synchronization between the on-premises servers and AWS.
Correct answer: B
Explanation
The correct answer is B because AWS DataSync is specifically designed for transferring data between on-premises storage and AWS services like Amazon EFS, providing secure and efficient synchronization. Option A lacks encryption and does not support bidirectional transfers out of the box. Option C is not ideal for ongoing synchronization and is more suited for bulk data transfer. Option D could provide a dedicated connection, but it does not facilitate the scheduled synchronization of shared file systems as required.
