Your company would like to leverage the AWS storage option and integrate it with the current on-premises infrastructure. There is a requirement of low latency access to the entire dataset and backup. Which of the following options would be best suited for this scenario?

Answer options:

A.Configure the Simple Storage Service.
B.Configure Storage Gateway Cached Volume.
C.Configure Storage Gateway Stored Volume.
D.Configure Amazon Glacier.

Correct Answer – C
Option A is incorrect because S3 is not used to provide low latency data access by integrating with the on-premises data center.
Option B is incorrect because cached volumes do not provide low latency to all the data.
Option C is correct because it provides low latency to all the data and maintains backup in AWS.
Option D is incorrect because Amazon Glacier is used to achieve data for a longer period of time, not related to the required scenario.
Cached volumes – Cached volumes offer substantial cost savings on primary storage and minimize the need to scale your storage on-premises. You also retain low-latency access to your frequently accessed data.
Stored volumes – Stored volumes provide your on-premises applications with low-latency access to their entire datasets. At the same time, they provide durable, offsite backups. With stored volumes, you maintain your volume storage on-premises in your data center. This solution is ideal if you want to keep data locally on-premises, because you need to have low-latency access to all your data, and also to maintain backups in AWS.
