Exam AWS Certified Developer - Associate DVA-C02 topic 1 question 178 discussion

Exam question from Amazon's AWS Certified Developer - Associate DVA-C02
Question #: 178
Topic #: 1
[All AWS Certified Developer - Associate DVA-C02 Questions]

A company is building an application for stock trading. The application needs sub-millisecond latency for processing trade requests. The company uses Amazon DynamoDB to store all the trading data that is used to process each trading request.

A development team performs load testing on the application and finds that the data retrieval time is higher than expected. The development team needs a solution that reduces the data retrieval time with the least possible effort.

Which solution meets these requirements?

  • A. Add local secondary indexes (LSIs) for the trading data.
  • B. Store the trading data in Amazon S3, and use S3 Transfer Acceleration.
  • C. Add retries with exponential backoff for DynamoDB queries.
  • D. Use DynamoDB Accelerator (DAX) to cache the trading data.

Selected Answer: D
DAX is an in-memory cache for DynamoDB that delivers fast read performance for your tables at scale by enabling you to get sub-millisecond response times for accessing your data. DAX is particularly beneficial for read-heavy and bursty workloads. Since it reduces the time to retrieve data, it's the most appropriate solution for achieving sub-millisecond latency in data retrieval.
