Snowflake Certification Practice Test

The classification of persistent tables in Snowflake primarily includes permanent tables, which are designed to store data for the long term. These tables retain data even after the session ends and are not subject to any time limits on data retention. Transient tables, while also able to hold data, have a different lifecycle: they persist data for a shorter duration and allow users to create temporary store without incurring costs associated with data recovery and failover capabilities that are inherent in permanent tables. Permanent tables are essential for storage needs that extend beyond transient operations, and applying the transient table aspect recognizes alternative data handling approaches where data might be useful for intermediate processes but does not need lasting retention. This makes the combination of permanent and transient tables the correct classification of persistent tables, as both have well-defined roles in data management within Snowflake. The other classifications mentioned do not align with the persistence concept as transient tables, while useful, are not classified with the same endurance as permanent ones. Regular and temporary tables also fall outside the true persistent designation, with regular tables being permanent and temporary tables being inherently session-based and therefore non-persistent.
