Close the documentation tab before you sit CDP-3002: nothing may be open. Nearly half the paper is Spark and another fifth is Spark tuning, so this guide studies the Cloudera Data Engineer exam in the order its weights suggest, then covers Airflow, Iceberg, the Data Engineering service, the online proctor and the $330 booking.
The score report says pass or fail and nothing else, so a timed practice run is the only place you will ever see a percentage. What the five Professional Data Engineer domains weigh, why the 70 percent figure is a rumour, and how the one hour renewal exam differs from the two hour standard one.
COF-C03 covers five domains, and Snowflake architecture alone carries 31 percent of them. Here is the full weighting split, the 750 of 1000 scaled pass mark, and a study order that starts where the platform actually makes sense.
