    MongoDB - Associate Developer (C100DEV)

    About this Certification

    An overview of what this certification covers

    The MongoDB Associate Developer (C100DEV) exam validates a candidate's ability to build applications on top of MongoDB using the document model, the query language, the aggregation pipeline, indexing, data modeling, MongoDB tooling, and an official MongoDB driver in one supported language. It assesses working knowledge of BSON and the document model, CRUD operations (including aggregation stages such as `$match`, `$group`, `$lookup`, and `$unwind`), index selection and query performance, schema design trade-offs (embedding vs. referencing), day-to-day tools (`mongosh`, MongoDB Compass, Atlas UI, `mongoimport`/`mongoexport`, `mongodump`/`mongorestore`), and driver-level connectivity, error handling, and multi-document ACID transactions. Candidates are expected to read and reason about `mongosh` commands, query and update documents, aggregation pipelines, and index definitions, and to choose the correct operator, stage, index, or modeling approach for a stated application requirement.
