AWS Certified Developer Associate DVA-C02 Practice Question

An application you are developing requires frequent, low-latency lookups of user preferences, which are saved in Amazon DynamoDB. To improve the performance, which technique would be BEST to implement?

  • Use a larger EC2 instance type to host the application for better performance.

  • Utilize Amazon DynamoDB Accelerator (DAX) to provide in-memory caching for DynamoDB data.

  • Increase the read capacity units (RCUs) of the DynamoDB table to handle higher read traffic.

  • Implement a custom in-memory object caching within the application to store user preferences.
