DBS-C01 Workload-Specific Database Design Practice Question
A company is designing a database for a social media analytics platform that requires: 1) storing relationships between users, posts, and interests; 2) running complex graph queries like 'find all friends of friends who like topic X'; 3) high availability with multi-region replication. Which TWO AWS services should they consider? (Choose TWO.)
⚠ Common exam trap
Many candidates confuse DynamoDB Global Tables (which provides multi-region replication) with graph database capabilities, overlooking that DynamoDB lacks native graph query support for multi-hop traversals like 'friends of friends'.

Correct answer & explanation
✓
Amazon Neptune
Amazon Neptune is a fully managed graph database service optimized for storing and querying highly connected data, such as user, post, and interest relationships. It supports property graph and RDF models, enabling complex graph queries like 'find all friends of friends who like topic X' using Gremlin or SPARQL. This directly satisfies the requirement for graph query capabilities. Amazon Aurora Global Database provides multi-region replication with low-latency global read operations and automatic failover, meeting the high availability and multi-region replication requirement. Together, Neptune handles the graph query workload, while Aurora Global Database provides the global distribution and disaster recovery needed for the analytics platform.
