Q64 — AWS SAA-C03 Ch.10

Question 64 of 100 | ← Chapter 10

Q664. A pharmaceutical company is developing a new drug. The volume of data that the company generates has grown exponentially over the past few months. The company's researchers regularly require a subset of the entire dataset to be immediately available with minimal lag. However. the entire dataset does not need to be accessed on a daily basis. All the data currently resides in on-premises storage arrays. and the company wants to reduce ongoing capital expenses.Which storaae solution should a solutions architect recommend to meet these requirements?

Correct Answer: C. Deploy an AWS Storage Gateway volume gateway with cached volumes with an Amazon S3 bucket as the target storage. Migrate the data to the Storage Gateway appliance

Explanation

To meet the requirements of the pharmaceutical company, specifically the need for immediate availability of a subset of the dataset with minimal lag, while reducing ongoing capital expenses, the solution that a solutions architect should recommend is:C. Deploy an AWS Storage Gateway volume gateway with cached volumes, with an Amazon S3 bucket as the target storage. Migrate the data to the Storage Gateway appliance.Here's the rationale behind this solution:Option C: Deploy an AWS Storage Gateway volume gateway with cached volumes, with an Amazon S3 bucket as the target storage. Migrate the data to the Storage Gateway appliance. The AWS Storage Gateway volume gateway with cached volumes is a suitable solution for this scenario. By deploying a volume gateway with cached volumes, the frequently accessed subset of the dataset can be stored on-premises, providing immediate availability with minimal lag. This subset of data is cached locally on the Storage Gateway appliance, allowing for fast access. The rest of the dataset resides in Amazon S3, reducing the need for on-premises storage arrays and lowering ongoing capital expenses.Option A: Run AWS DataSync as a scheduled cron job to migrate the data to an Amazon S3 bucket on an ongoing basis.While AWS DataSync can be used to migrate data to an Amazon S3 bucket, it does not provide the immediate availability and minimal lag required by the researchers. DataSync is more suitable for one-time or periodic data migration rather than providing real-time access to subsets of the dataset.Option B: Deploy an AWS Storage Gateway file gateway with an Amazon S3 bucket as the target storage.Migrate the data to the Storage Gateway appliance.The AWS Storage Gateway file gateway is designed for file-level access, and it may not be the most efficient solution for handling large volumes of data. Additionally, it doesn't specifically address the need for immediate availability of a subset of the dataset with minimal lag.Option D: Configure an AWS Site-to-Site VPN connection from the on-premises environment to AWS. Migrate data to an Amazon Elastic File System (Amazon EFS) file system. While Amazon EFS provides scalable file storage in the cloud, it may not be the most cost-effective solution for reducing ongoing capital expenses. Additionally, it doesn't directly address the requirement for immediate availability of a subset of the dataset with minimal lag.Therefore, the most suitable solution to meet the requirements is to deploy an AWS Storage Gateway volume gateway with cached volumes, with an Amazon S3 bucket as the target storage (Option C). This solution provides the necessary balance between immediate availability, minimal lag, and cost reduction by leveraging on-premises storage for frequently accessed data and Amazon S3 for the rest of the dataset.
