Topic 1 Question 254
A financial services company loaded millions of historical stock trades into an Amazon DynamoDB table. The table uses on-demand capacity mode. Once each day at midnight, a few million new records are loaded into the table. Application read activity against the table happens in bursts throughout the day. and a limited set of keys are repeatedly looked up. The company needs to reduce costs associated with DynamoDB.
Which strategy should a solutions architect recommend to meet this requirement?
Deploy an Amazon ElastiCache cluster in front of the DynamoDB table
Deploy DynamoDB Accelerator (DAX). Configure DynamoDB auto scaling. Purchase Savings Plans in Cost Explorer.
Use provisioned capacity mode. Purchase Savings Plans in Cost Explorer.

It's D. Purchase Savings Plans in Cost Explorer is not for DynamoDB. At least not today.

The D looks like a perfect solution. But the question is only asking to reduce the cost, so I would like to choose C instead.

Repeated lookups = DAX Avoid bursts = Provisioned Capacity
