SnowPro Core Recertification Exam

I came from a SQL Server background and needed COF-R02 to prove my Snowflake skills at a new job. The practice problems on streams, tasks, and Snowpipe covered things I had never touched before. Two weeks of focused prep and I cleared it.

Virtual warehouse sizing finally clicked after drilling these.

Nailed the data sharing section thanks to the practice sets.

Some questions felt similar to each other, which got repetitive near the end. That said, the coverage of Snowflake resource monitors and continuous data protection was thorough and clearly on point for the real exam. Passed my recertification on the second attempt - still worth it.

Semi-structured data and VARIANT always tripped me up - the practice questions on JSON querying made those COF-R02 topics feel manageable.

The COF-R02 digs into RBAC and row-level security more than I expected - these practice questions helped me stop second-guessing myself on those.
