AWS Certified Developer Associate DVA-C02 Practice Question

To ensure that the most up-to-date data is retrieved, you should perform a strongly consistent read. Strongly consistent reads return results that reflect all successful writes that occurred before the read. By contrast, an eventually consistent read can return stale data because replication to all copies may not have completed yet. Write-through and read-through are caching strategies, not DynamoDB consistency models, so they do not guarantee immediate consistency.
