Related credentials include MongoDB Certified Database Administrator Associate, MongoDB Certified Developer Associate.
60 questions in 90 minutes. That combination rewards candidates who've trained their pace, not just their memory — so before the real thing, run full timed sessions in the ITExamDownload engine, practice flagging hard questions instead of fighting them, and learn what your sustainable per-question rhythm feels like.

We have a movies collection with the following document structure: { _id: ObjectId("573a1390f29313caabcd6223"), genres: [ 'Comedy', 'Drama', 'Family' ], title: 'The Poor Little Rich Girl', released: ISODate("1917-03-05T00:00:00.000Z"), year: 1917, imdb: { rating: 6.9, votes: 884, id: 8443 } } We need to use Aggregation Framework to fetch all movies from this collection where 'Drama' is not in genres list and the minimum 'imdb.votes' is at least 100.
