Question

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?

Accepted Answer

Correct answer: D. The correct answer is D. Option D: Deploy DynamoDB Accelerator (DAX). Use provisioned capacity mode. Configure DynamoDB auto scaling. Auto Scaling adjusts capacity automatically to match demand, improving availability and cost efficiency. Amazon DynamoDB is a fully managed, serverless NoSQL database with single-digit millisecond latency and automatic scaling. DynamoDB Accelerator (DAX) adds an in-memory cache for microsecond DynamoDB reads. This option delivers the requirement at the lowest cost.
