DEA-C02
The SnowPro Advanced: Data Engineer (DEA-C02) is Snowflake's expert-level credential for engineers who move, transform, and protect data at scale on the Snowflake Data Cloud. It is one of the hardest exams in the Snowflake track — a single scaled score of 750 separates pass from fail, and a near-miss means another $375 attempt and a delay before your skills are validated for a promotion, client engagement, or partner-tier requirement. This page breaks down exactly what the exam tests, how it's delivered, and how to get it done right the first time.

How the DEA-C02 is built — at a glance
65
A mix of multiple choice, multiple select, and interactive items such as drag-and-drop and matching. A handful of unscored pretest items can appear and do not affect your result.
115
About 1 minute 45 seconds per question on average. The pace is tight for an Advanced exam, so reading scenario stems quickly and accurately matters.
750
Scoring runs 0–1000 and you need 750 to pass. Results are reported as pass or fail with a scaled score — there is no fixed percentage of correct answers published.
DEA-C02 leans heavily on scenario-based questions: you'll be given a data-engineering situation and asked which approach, feature, or SQL construct is correct. Multiple-select items require every correct option (and no incorrect ones) to earn credit, so partial knowledge is punished. With 115 minutes for 65 questions, flagging and returning to long stems is the right strategy.
Snowflake uses scaled scoring rather than a raw percentage, which lets it balance difficulty across exam versions. Your final report shows a single scaled score against the 750 cut, plus a relative breakdown by domain so you can see where you were strong or weak. There is no penalty for guessing, so answer every question.
Five weighted domains — bars show each domain's share of the scored questions
Ingestion and unloading: Snowpipe, Snowpipe Streaming, COPY INTO, stages, external tables, the Kafka connector, plus replication and sharing across accounts and clouds.
Streams and tasks, Dynamic Tables, Snowpark (Python/Java/Scala), UDFs and stored procedures, semi-structured data (VARIANT, FLATTEN), and near-real-time pipelines.
Warehouse sizing and scaling, query profiling, micro-partition pruning, clustering keys, caching, the search optimization service, and managing compute cost.
Time Travel, Fail-safe, zero-copy cloning, continuous data protection, table types (transient, temporary, permanent), and storage cost behavior.
Role-based access control, masking and row-access policies, object tagging, data classification, secure views and shares, and access history for auditing.
Weights are taken from the official Snowflake DEA-C02 study guide. Data Movement and Data Transformation together account for over half the exam, so depth in ingestion, streaming, and pipeline-building is where most candidates win or lose the 750 cut.
Two ways to sit the DEA-C02 — and what to expect on test day
You take the exam from a private room at home or in the office, monitored remotely by a Pearson VUE OnVUE proctor. Beforehand you'll run a system check, do a webcam room scan, and verify a government photo ID. No scratch paper, second monitor, phone, or other person is allowed in the room.
You sit the exam in a quiet, monitored room at a Pearson VUE center. Staff verify your ID, store your belongings, and supervise the room. This is the simpler option if your home setup or connection isn't reliable enough for a remote-proctored Advanced exam.
A valid, unexpired government photo ID with a name that matches your exam registration exactly. The OnVUE proctor captures your photo and ID before the exam unlocks.
A clear desk, no second screen, no notes, and a 360° webcam scan of the room. Close all other applications — OnVUE locks down your machine for the session.
Stay on-camera and in frame the entire time. There are no scheduled breaks in the 115 minutes; leaving your seat, talking aloud, or losing connection can flag the session.
DEA-C02 is built for hands-on Snowflake data engineers
Experience-driven — and one of the harder Snowflake exams
Difficulty: DEA-C02 is a genuinely hard, experience-based exam. The scenario questions assume you've built real pipelines, tuned warehouses, and debugged ingestion — book knowledge alone rarely clears the 750 cut. Most candidates underestimate the depth on Snowpark, Dynamic Tables, and Streaming, which is exactly the pressure point our help is designed to remove.
The SnowPro Advanced: Data Engineer is a high-stakes, time-boxed exam standing between you and a promotion, partner tier, or client requirement. Exam Assist pairs you with a vetted Snowflake specialist and works on a pay-after-you-pass model — so the risk sits with us, not you. No upfront fee, guaranteed results: Exam Assist handles the sitting end to end, and you settle only after the verified result.
Tell us your target date, delivery method (OnVUE or center), and your experience with Snowpark, streams, and ingestion. Takes a couple of minutes over WhatsApp, Telegram, or Discord.
We review your timeline and the DEA-C02 domains and tell you plainly whether it's realistic — before any money is discussed. If it isn't a fit, we say so.
Exam Assist handles the sitting end to end. You're matched with a Snowflake specialist who maps the work around the five weighted domains and the OnVUE environment — discreetly and confidentially.
You only pay once your passing score is confirmed on your official Snowflake result. No verified result, nothing owed.
