Exam AWS Certified Solutions Architect - Associate SAA-C03 topic 1 question 767 discussion

Exam question from Amazon's AWS Certified Solutions Architect - Associate SAA-C03
Question #: 767
Topic #: 1
[All AWS Certified Solutions Architect - Associate SAA-C03 Questions]

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 storage solution should a solutions architect recommend to meet these requirements?

  • A. Run AWS DataSync as a scheduled cron job to migrate the data to an Amazon S3 bucket on an ongoing basis.
  • 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.
  • 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.
  • 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.

B. Deploying an AWS Storage Gateway file gateway with an Amazon S3 bucket as the target storage would require the entire dataset to be stored in Amazon S3, which might not be cost-effective considering that only a subset of the data needs to be accessed regularly. Additionally, accessing data directly from S3 might introduce latency. so correct option is C bcz AWS Storage Gateway volume gateway with cached volumes allows the company to keep frequently accessed data locally on-premises while storing the entire dataset in Amazon S3. This solution provides immediate access to the subset of data with minimal lag, as frequently accessed data is cached locally. It also reduces ongoing capital expenses as it leverages Amazon S3 storage, which is cost-effective.

Both B and C store the entire data set in Amazon S3 and the AWS Storage Gateway file gateway also supports local caching. I do not know if it is B or C for me.

Selected Answer: B
Volume Gateway is designed for block storage (EBS volumes), not file storage. It is not the best fit for this use case, which involves file-based data access.

AnswerC Deploying an AWS Storage Gateway volume gateway with cached volumes will allow to store all data in AWS but the most frequently accessed data will be stored/cached localy (on-premises) = low latency for most used data while all data will be stored in the cloud. https://docs.aws.amazon.com/storagegateway/latest/vgw/StorageGatewayConcepts.html#storage-gateway-cached-concepts

A storage guy here.. the question is not clear enough to give a definitive answer between B and C, as both can do the job. An "on-prem storage array" can be any of the three: - File array (serving any file protocol, e.g. NFS/SMB) -> requiring a file gateway (supports caching of the most recently used data) - Block array (iSCSI/Fibre Channel) -> requiring a volume gateway (supports cached volumes most recently used data) - Combo (providing both File and Block protocols) Something is clearly missing in the question in order to give a definitive answer between B and C.
