# AWS-Certified-Big-Data---Specialty — Question 427

**Type:** multiple_choice
**Topics:** topic_1

## Question

A company receives data sets coming from external providers on Amazon S3. Data sets from different providers are dependent on one another. Data sets will arrive at different times and in no particular order.
A data architect needs to design a solution that enables the company to do the following:
✑ Rapidly perform cross data set analysis as soon as the data becomes available
✑ Manage dependencies between data sets that arrive at different times
Which architecture strategy offers a scalable and cost-effective solution that meets these requirements?

## Correct Answer

_See scenario._

## Explanation

I'll go with D. DDB is more apt for storing configuration data instead of storing in a cache. Also Redis would have limitation is size so it's not a scale-able approach.
