The MongoDB Competency (Intermediate Level) benchmark measures your recognition of how to interact with a MongoDB Atlas cluster from a variety of clients and perform CRUD operations with MongoDB Atlas. You will be evaluated on your skills in connecting to a MongoDB Atlas cluster, performing a bulk upload of data into a MongoDB collection, invoking MongoDB shell functions to perform read operations, filtering documents based on attributes, creating and building multistage pipelines, and more. A learner who scores high on this benchmark demonstrates good hands-on experience interacting with a MongoDB Atlas cluster and performing data retrieval.
