Question 17 of 100 | ← Chapter 10

Q617. A recent analysis of a company's IT expenses highlights the need to reduce backup costs. The company's chief information officer wants to simplify the on-premises backup infrastructure and reduce costs by eliminating the use of physical backup tapes. The company must preserve the existing investment in the on-premises backup applications and workflows.What should a solutions architect recommend?

Correct Answer: D. Set up AWS Storage Gateway to connect with the backup applications using the iSCSI-virtual tape library (VTL) interface.

Explanation

To simplify the on-premises backup infrastructure and reduce costs by eliminating the use of physical backup tapes while preserving the existing investment in the on-premises backup applications and workflows, a solutions architect should recommend the following:D. Set up AWS Storage Gateway to connect with the backup applications using the iSCSI-virtual tape library (VTL) interface.Setting up an AWS Storage Gateway with the iSCSI-virtual tape library (VTL) interface allows the company to replace physical backup tapes with virtual tapes stored in Amazon S3 or Amazon Glacier. This solution integrates seamlessly with the existing on-premises backup applications and workflows, preserving the existing investment. The backup applications can continue to work with the virtual tapes through the iSCSI interface, providing a smooth transition without requiring significant changes to the backup infrastructure.Option A is not the best choice:A. Setting up AWS Storage Gateway to connect with the backup applications using the NFS interface does not address the need to eliminate physical backup tapes. NFS is a file-based protocol, and it may not be compatible with the existing backup applications and workflows.Option B is not the best choice either:B. Setting up an Amazon EFS file system that connects with the backup applications using the NFS interface does not address the requirement to eliminate physical backup tapes. Moreover, EFS is a file storage service and may not provide the required integration with the existing backup applications.Option C is not the best choice either:C. Setting up an Amazon EFS file system that connects with the backup applications using the iSCSI interface is not a suitable solution for eliminating physical backup tapes. EFS is not designed for backup purposes, and the iSCSI interface may not integrate well with the existing backup applications and workflows.Therefore, the most appropriate recommendation is to set up AWS Storage Gateway to connect with the backup applications using the iSCSI-virtual tape library (VTL) interface (option D). This solution allows the company to transition from physical backup tapes to virtual tapes stored in Amazon S3 or Amazon Glacier while leveraging their existing backup applications and workflows.
