AWS Certified Solutions Architect – Associate (SAA-C02) — Question 91

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?

Answer options

• A. Set up AWS Storage Gateway to connect with the backup applications using the NFS interface.
• B. Set up an Amazon EFS file system that connects with the backup applications using the NFS interface.
• C. Set up an Amazon EFS file system that connects with the backup applications using the iSCSI interface.
• D. Set up AWS Storage Gateway to connect with the backup applications using the iSCSI-virtual tape library (VTL) interface.

Correct answer: D

Explanation

The correct answer is D because AWS Storage Gateway with the iSCSI-VTL interface allows for a seamless transition from physical tape to a virtual tape solution, preserving existing workflows. Options A and B do not utilize the VTL interface, which is crucial for compatibility with current backup applications. Option C also fails to use the appropriate VTL interface and instead suggests using iSCSI without the virtual tape capability.
