Snowflake SnowPro Core Certification Exam Sample Questions (Q869-Q874):

NEW QUESTION # 869
Which SQL commands, when committed, will consume a stream and advance the stream offset? (Choose two.)

Answer: A,C

Explanation:
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.

NEW QUESTION # 870
When unloading data with the COPY into <location> command, what is the purpose of the PARTITION BY <expression> parameter option?

Answer: B

Explanation:
The PARTITION BY <expression> parameter option in the COPY INTO <location> command is used to split the output into multiple files based on the distinct values of the specified expression. This feature is particularly useful for organizing large datasets into smaller, more manageable files and can help with optimizing downstream processing or consumption of the data. For example, if you are unloading a large dataset of transactions and use PARTITION BY DATE(transactions.transaction_date), Snowflake generates a separate output file for each unique transaction date, facilitating easier data management and access.
This approach to data unloading can significantly improve efficiency when dealing with large volumes of data by enabling parallel processing and simplifying data retrieval based on specific criteria or dimensions.

NEW QUESTION # 871
How can a row access policy be applied to a table or a view? (Choose two.)

Answer: A,D


NEW QUESTION # 872
Which command is used to lake away staged files from a Snowflake stage after a successful data ingestion?

Answer: B

Explanation:
The REMOVE command is used in Snowflake to delete files from a stage after they have been successfully ingested into Snowflake tables. This command helps manage storage by allowing users to clean up staged files that are no longer needed, ensuring that the stage does not accumulate unnecessary data over time. Unlike DELETE, DROP, or TRUNCATE commands, which are used for managing data within Snowflake tables or dropping objects, REMOVE specifically targets the management of files in stages.References: Snowflake Documentation on Stages and File Management


NEW QUESTION # 873

Answer: B

Explanation:
* The Query Acceleration Service is available starting with the Enterprise Edition of Snowflake.
