Q701. A company has an on-premises data center that is running out of storage capacity. The company wants to migrate its storage infrastructure to AWS while minimizing bandwidth costs. The solution must allow for immediate retrieval of data at no additional cost.How can these requirements be met?

Correct Answer: B. Deploy AWS Storage Gateway using cached volumes.Use Storage Gateway to store data in Amazon S3 while retaining copies of frequently accessed data subsets locally.

Explanation

To meet the requirements of migrating storage infrastructure to AWS while minimizing bandwidth costs and allowing for immediate retrieval of data at no additional cost, the recommended solution would be:B. Deploy AWS Storage Gateway using cached volumes. Use Storage Gateway to store data in Amazon S3 while retaining copies of frequently accessed data subsets locally. Option B provides a solution that fulfills the requirements:- Deploy AWS Storage Gateway using cached volumes: AWS Storage Gateway is a hybrid cloud storage service that enables on-premises applications to seamlessly use AWS cloud storage. By deploying Storage Gateway with cached volumes, frequently accessed data subsets are stored locally, allowing for immediate retrieval without incurring additional costs for data transfer.- Use Storage Gateway to store data in Amazon S3 while retaining copies of frequently accessed data subsets locally: With cached volumes, Storage Gateway maintains a local cache of frequently accessed data on-premises, while asynchronously backing up the data to Amazon S3. This ensures that data is readily available locally while also providing durability and off-site backup in the cloud.Option A, deploying Amazon S3 Glacier Vault and enabling expedited retrieval, is not the recommended solution as expedited retrieval incurs additional costs. While Glacier provides low-cost storage for long-term archiving, it does not meet the requirement for immediate retrieval at no additional cost.Option C, deploying AWS Storage Gateway using stored volumes to store data locally and asynchronously backing up point-in-time snapshots of the data to Amazon S3, does not fulfill the immediate retrieval requirement at no additional cost. Stored volumes are designed for primary data storage, not for frequently accessed subsets.Option D, deploying AWS Direct Connect to connect with the on-premises data center and configuring AWS Storage Gateway to store data locally while asynchronously backing up point-in-time snapshots of the data to Amazon S3, does not address the requirement of minimizing bandwidth costs. Additionally, using Direct Connect may incur additional costs for the dedicated network connection.Therefore, the best solution to meet the requirements is B: Deploy AWS Storage Gateway using cached volumes. Use Storage Gateway to store data in Amazon S3 while retaining copies of frequently accessed data subsets locally. This solution provides immediate data retrieval at no additional cost, minimizes bandwidth costs, and maintains data durability and off-site backup in Amazon S3.
