Exactprep SnowPro-Core Questions

 Stored procedures in Snowflake can perform a variety of database operations, including DDL and DML, whereas UDFs are designed to return values and cannot execute database operations1.

 Snowflake’s column level security features include Dynamic Data Masking and External Tokenization. Dynamic Data Masking uses masking policies to selectively mask data at query time, while External Tokenization allows for the tokenization of data before loading it into Snowflake and detokenizing it at query runtime5.

 Running EXPLAIN and SHOW commands, as well as running a custom query, consume virtual warehouse credits in the Snowflake environment. These activities require computational resources, and therefore, credits are used to account for the usage of these resources. References: [COF-C02] SnowPro Core Certification Exam Study Guide

Snowflake supports reader accounts, which are a type of account that allows data providers to share data with consumers who are not Snowflake customers. However, for data sharing to occur, the consumer needs to become a licensed Snowflake customer because data sharing is only supported between Snowflake accounts.
