DEA-C01 Data Store Management Practice Question
Which TWO data stores are considered fully managed, serverless, and suitable for storing JSON documents?
⚠ Common exam trap
AWS often tests the distinction between fully managed serverless services (DocumentDB, DynamoDB) and those requiring provisioning or cluster management (Redshift, ElastiCache, RDS), leading candidates to mistakenly select ElastiCache for Redis due to its JSON module support, ignoring its non-serverless nature and primary use as a cache.
