AWS Certified Solutions Architect Professional Practice (SAP-C02) Practice Exam

Amazon DocumentDB (with MongoDB compatibility) is a fully managed service designed to run MongoDB workloads in the cloud. It provides a MongoDB-compatible API, so applications can use the same drivers and tools they’re already using, while AWS handles the heavy lifting of operations. You set up a cluster, and AWS takes care of provisioning, patching, backups, and monitoring. Storage scales automatically, and you can scale compute by adjusting instance types and add read replicas to handle higher read throughput. It integrates with AWS security and monitoring features (VPC, IAM, CloudWatch), making it easy to deploy, operate, and grow MongoDB-compatible databases without managing the underlying infrastructure. DynamoDB, Neptune, and ElastiCache serve different purposes (general NoSQL, graph databases, and in-memory caching, respectively) and aren’t MongoDB-compatible managed options, which is why DocumentDB is the fit for MongoDB-compatible needs.
