New Release COF-C03 SnowPro Core Certification Questions

Operations that do not require compute resources are typically those that can leverage previously cached results. However, if no queries have been executed previously, all the given operations would require compute to execute. It’s important to note that certain operations like DDL statements and queries that hit the result cache do not consume compute credits2.

The SQL commands that consume a stream and advance the stream offset are those that result in changes to the data, such as UPDATE and INSERT operations. Specifically, ‘UPDATE TABLE FROM STREAM’ and ‘INSERT INTO TABLE SELECT FROM STREAM’ will consume the stream and move the offset forward, reflecting the changes made to the data.

 Organizing files into logical paths can significantly improve the efficiency of data loading from an external stage. This practice helps in managing and locating files easily, which can be particularly beneficial when dealing with large datasets or complex directory structures1.

The query results cache can be used as long as the data in the table has not changed since the last time the query was run. If the underlying data has changed, Snowflake will not use the cached results and will re-execute the query1.
