NEW QUESTION # 87
Which governance feature is supported by all Snowflake editions?
- A. OBJECT_DEPENDENCIES View
- B. Row access policies
- C. Object tags
- D. Masking policies
Answer: A
Explanation:
Snowflake's governance features vary across different editions, but the OBJECT_DEPENDENCIES view is supported by all Snowflake editions. This feature is part of Snowflake's Information Schema and is designed to help users understand the dependencies between various objects in their Snowflake environment.
The OBJECT_DEPENDENCIES view provides a way to query and analyze the relationships and dependencies among different database objects, such as tables, views, and stored procedures. This is crucial for governance, as it allows administrators and data engineers to assess the impact of changes, understand object relationships, and ensure proper management of data assets.
Object tags, masking policies, and row access policies are more advanced features that offer fine-grained data governance capabilities such as tagging objects for classification, dynamically masking sensitive data based on user roles, and controlling row-level access to data. These features may have varying levels of support across different Snowflake editions, with some features being exclusive to higher-tier editions.
NEW QUESTION # 88
The VALIDATE table function has which parameter as an input argument for a Snowflake user?
- A. Last_QUERY_ID
- B. JOB_ID
- C. UUID_STRING
- D. CURRENT_STATEMENT
Answer: C
Explanation:
The VALIDATE table function in Snowflake would typically use a unique identifier, such as a UUID_STRING, as an input argument. This function is designed to validate the data within a table against a set of constraints or conditions, often requiring a specific identifier to reference the particular data or job being validated.
References:
There is no direct reference to a VALIDATE table function with these specific parameters in Snowflake documentation. It seems like a theoretical example for understanding function arguments. Snowflake documentation on UDFs and system functions can provide guidance on how to create and use custom functions for similar purposes.

NEW QUESTION # 95
Which Snowflake table type is only visible to the user who creates it, can have the same name as permanent tables in the same schema, and is dropped at the end of the session?
- A. Transient
- B. Local
- C. User
- D. Temporary
Answer: D
Explanation:
In Snowflake, a Temporary table is a type of table that is only visible to the user who creates it, can have the same name as permanent tables in the same schema, and is automatically dropped at the end of the session in which it was created. Temporary tables are designed for transient data processing needs, where data is needed for the duration of a specific task or session but not beyond. Since they are automatically cleaned up at the end of the session, they help manage storage usage efficiently and ensure that sensitive data is not inadvertently persisted.

NEW QUESTION # 98
What criteria does Snowflake use to determine the current role when initiating a session? (Select TWO).
- A. If no role was specified as part of the connection and a default role has been defined for the Snowflake user, that role becomes the current role.
- B. If a role was specified as part of the connection and that role has not been granted to the Snowflake user, it will be ignored and the default role will become the current role.
- C. If a role was specified as part of the connection and that role has been granted to the Snowflake user, the specified role becomes the current role.
- D. If no role was specified as part of the connection and a default role has not been set for the Snowflake user, the session will not be initiated and the log in will fail.
- E. If a role was specified as part of the connection and that role has not been granted to the Snowflake user, the role is automatically granted and it becomes the current role.
Answer: A,C
Explanation:
When initiating a session in Snowflake, the system determines the current role based on the user's connection details and role assignments. If a user specifies a role during the connection, and that role is already granted to them, Snowflake sets it as the current role for the session. Alternatively, if no role is specified during the connection, but the user has a default role assigned, Snowflake will use this default role as the current session role. These mechanisms ensure that users operate within their permissions, enhancing security and governance within Snowflake environments.

NEW QUESTION # 103
To use the overwrite option on insert, which privilege must be granted to the role?
- A. DELETE
- B. UPDATE
- C. SELECT
- D. truncate
Answer: A
Explanation:
To use the overwrite option on insert in Snowflake, the DELETE privilege must be granted to the role. This is because overwriting data during an insert operation implicitly involves deleting the existing data before inserting the new data.
Understanding the Overwrite Option: The overwrite option (INSERT OVERWRITE) allows you to replace existing data in a table with new data. This operation is particularly useful for batch-loading scenarios where the entire dataset needs to be refreshed.
Why DELETE Privilege is Required: Since the overwrite operation involves removing existing rows in the table, the executing role must have the DELETE privilege to carry out both the deletion of old data and the insertion of new data.
Granting DELETE Privilege:
To grant the DELETE privilege to a role, an account administrator can execute the following SQL command:
sqlCopy code
GRANT DELETE ON TABLE my_table TO ROLE my_role;
NEW QUESTION # 104
A user wants to access stored in a stage without authenticating into Snowflake.
Which type of URL should be used?
- A. File URL
- B. Scoped URL
- C. Staged URL
- D. Pre-signed URL
Answer: D
Explanation:
A pre-signed URL provides a way to access objects stored in a stage without requiring authentication to Snowflake. This URL contains all the necessary information for access control, including an expiration time, and it's signed by the service's credentials. This mechanism allows users or applications to access specific files stored in a cloud storage location (stage) directly, bypassing the need to authenticate into Snowflake, ensuring secure and temporary access to the data.References: Snowflake Documentation on Stages and Data Loading
