SAP-C02 Design for New Solutions Practice Question
A company is designing a new application that requires a fully managed NoSQL database with single-digit millisecond latency. The application needs to handle sudden spikes in read traffic without manual intervention. Which AWS service should the company choose?
⚠ Common exam trap
Candidates often confuse Amazon ElastiCache (a caching layer) with a primary NoSQL database, or assume that Amazon Aurora's MySQL compatibility makes it a NoSQL option, when in fact DynamoDB is the only fully managed NoSQL service among the choices that meets the latency and auto-scaling requirements.

Amazon DynamoDB
Amazon DynamoDB is a fully managed NoSQL key-value and document database that delivers single-digit millisecond latency at any scale. It supports auto-scaling of read/write capacity based on traffic patterns, enabling the application to handle sudden spikes in read traffic without manual intervention.
