Individual exam pages show the date each bank was last reviewed.
Frequently asked questions
Which data platform certification should I start with?
It depends on your stack. If you work with Snowflake, SnowPro Core (COF-C02) is the foundational credential. If you build pipelines on Databricks and Apache Spark, the Databricks Certified Data Engineer Associate is the entry-level data-engineering exam. Both are associate-level and need no formal prerequisites.
Are these official Snowflake or Databricks exam questions?
