Question 767

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?

    Correct Answer: C

    Deploying an 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 ensures that the required subset of data is immediately available with minimal lag due to local caching, while the rest of the dataset is stored cost-effectively in the cloud, thus reducing ongoing capital expenses.

Option C

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.

lenotcOption: C

storage array, also known as a disk array so AWS Storage Gateway volume. its a trap

ninasgxOption: C

require a subset of the entire dataset => cached volumes

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.

storage arrays = Volume Gateway

MattBJOption: C

C is correct. Using AWS Storage Gateway volume gateway with cached volumes provide local access to the file.

ScheldonOption: C

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
