Snowflake SnowPro Core Certification Exam Sample Questions (Q365-Q370):

NEW QUESTION # 365
What action should be taken if a Snowflake user wants to share a newly created object in a database with consumers?

Answer: D

Explanation:
When a Snowflake user wants to share a newly created object in a database with consumers, the correct action to take is to use the GRANT privilege ... TO SHARE command to grant the necessary privileges for the object to be shared. This approach allows the object owner or a user with the appropriate privileges to share database objects such as tables, secure views, and streams with other Snowflake accounts by granting access to a named share.
The GRANT statement specifies which privileges are granted on the object to the share. The object remains in its original location; sharing does not duplicate or move the object. Instead, it allows the specified share to access the object according to the granted privileges.
For example, to share a table, the command would be:
GRANT SELECT ON TABLE new_table TO SHARE consumer_share;
This command grants the SELECT privilege on a table named new_table to a share named consumer_share, enabling the consumers of the share to query the table.
Automatic sharing, dropping and re-adding the object, or recreating the object with a different name are not required or recommended practices for sharing objects in Snowflake. The use of the GRANT statement to a share is the direct and intended method for this purpose.

NEW QUESTION # 367

Answer: B


NEW QUESTION # 368
Which data formats are supported by Snowflake when unloading semi-structured data? (Select TWO).

Answer: A,C

Explanation:
Snowflake supports a variety of file formats for unloading semi-structured data, among which Parquet and Newline Delimited JSON (NDJSON) are two widely used formats.
* B. Binary file in Parquet: Parquet is a columnar storage file format optimized for large-scale data processing and analysis. It is especially suited for complex nested data structures.
* D. Newline Delimited JSON (NDJSON): This format represents JSON records separated by newline characters, facilitating the storage and processing of multiple, separate JSON objects in a single file.
These formats are chosen for their efficiency and compatibility with data analytics tools and ecosystems, enabling seamless integration and processing of exported data.

NEW QUESTION # 369
A Snowflake user needs to share a data set and wants it to be available to any Snowflake account that resides in the same cloud region. What is the recommended way to do this?

Answer: C

Explanation:
The correct answer is A. Use a public listing .
A public listing on Snowflake Marketplace allows a provider to make a data product discoverable and available to Snowflake consumers. If the goal is to make a dataset available broadly to Snowflake accounts in the same supported region, a public listing is the recommended sharing method.
Why A is correct:
Public listings are designed for broad distribution of datasets, applications, or services to Snowflake consumers. They are more scalable and discoverable than direct shares when the target audience is many or any Snowflake accounts.
Why the other options are incorrect:
B). A direct share is used to share data with specific known consumer accounts, not broadly with any account in a region.
C). A Data Exchange is a private data hub for a controlled group of members, not the best method for making data broadly available to any Snowflake account.
D). An external stage is used to reference files in cloud storage. It is not Snowflake's recommended secure sharing mechanism for making datasets available to Snowflake accounts.
Official Snowflake documentation reference:
Snowflake documentation describes listings as the mechanism for offering data products to consumers through Snowflake Marketplace, while direct shares are for sharing with specific accounts.
