DBS-C01 Workload-Specific Database Design Practice Question

A company needs a fully managed graph database for a social networking application that requires real-time recommendations based on friend connections. Which AWS service should they use?

⚠ Common exam trap

Many exam-takers confuse Amazon DocumentDB or DynamoDB as suitable for graph workloads because they can store JSON with references, but they lack native graph traversal engines and query languages (Gremlin/SPARQL) required for efficient relationship queries.
