AWS Certified Developer Associate DVA-C02 Practice Question

A developer is implementing an application that requires frequent retrieval of items from an Amazon DynamoDB table. To optimize performance, the application needs to minimize latency and reduce the number of network calls. Given the need for efficient data access patterns, which method should the developer use when implementing code that interacts with the DynamoDB table using the AWS SDK?

  • Employ a Scan operation to fetch all table items and filter as needed.

  • Use PutItem calls with a filter to only insert the desired items.

  • Utilize BatchGetItem for batch retrieval of items.

  • Perform individual GetItem operations for each item.
