Question 49 of 100 | ← Chapter 13

Q949. A company currently stores 5 TB of data in on-premises block storage systems. The company's current storage solution provides limited space for additional data. The company runs applications on premises that must be able to retrieve frequently accessed data with low latency. The company requires a cloud-based storage solution.Which solution will meet these requirements with the MOST operational efficiency?

Correct Answer: B. Use an AWS Storage Gateway Volume Gateway with cached volumes as iSCSl targets

Explanation

The solution that meets the requirements with the MOST operational efficiency is B. Use an AWS Storage Gateway Volume Gateway with cached volumes as iSCSI targets.Here's why:Low Latency: Cached volumes in Storage Gateway provide low latency access to frequently accessed data. This is crucial for applications that require fast data retrieval. Operational Efficiency: Cached volumes minimize the need for data transfers between on-premises and AWS, reducing network traffic and operational overhead.iSCSI Support: iSCSI is a widely used protocol for block storage, allowing the company to easily integrate the Storage Gateway with their existing applications.Cloud-Based Storage: Storage Gateway seamlessly integrates with Amazon S3, providing a cloud-based storage solution without requiring major application changes.Why other options are less suitable:A. Use Amazon S3 File Gateway. Integrate S3 File Gateway with the on-premises applications to store and directly retrieve files by using the SMB file system: While S3 File Gateway offers SMB access to S3, it doesn't provide low-latency access to frequently accessed data. C. Use an AWS Storage Gateway Volume Gateway with stored volumes as iSCSI targets: Stored volumes require data to be transferred to AWS, increasing network traffic and latency. This is less efficient for frequently accessed data.D. Use an AWS Storage Gateway Tape Gateway. Integrate Tape Gateway with the on-premises applications to store virtual tapes in Amazon S3: Tape Gateway is designed for long-term archival storage, not for frequently accessed data. It would not meet the low-latency requirement.In summary:Option B provides the most operationally efficient solution by combining low-latency cached volumes with iSCSI support and seamless integration with Amazon S3. This allows the company to migrate its data to the cloud while maintaining the performance requirements of its applications.
