Which file function generates a SnowFlake-hosted URL that must be authenticated when used?
- A. BUILD_STAGE_FILE_URL
- B. GET_STATE_LOCATION
- C. BUILD_SCOPED_FILE_URL
- D. GET_PRESENT_URL
Answer: A
Explanation:
* Purpose: The BUILD_STAGE_FILE_URL function generates a temporary, pre-signed URL that allows you to access a file within a Snowflake stage (internal or external). This URL requires authentication to use.
* Key Points:
* Security: The URL has a limited lifespan, enhancing security.
* Use Cases: Sharing staged data with external tools or applications, or downloading it directly.
* Snowflake Documentation (BUILD_STAGE_FILE_URL): https://docs.snowflake.com/en/sql-reference

NEW QUESTION # 180
What happens to the privileges granted to Snowflake system-defined roles?
- A. The privileges cannot be revoked.
- B. The privileges can be revoked by an ACCOUNTADMIN.
- C. The privileges can be revoked by an orgadmin.
- D. The privileges can be revoked by any user-defined role with appropriate privileges.
Answer: A
Explanation:
The privileges granted to Snowflake's system-defined roles cannot be revoked. System-defined roles, such as SYSADMIN, ACCOUNTADMIN, SECURITYADMIN, and others, come with a set of predefined privileges that are essential for the roles to function correctly within the Snowflake environment. These privileges are intrinsic to the roles and ensure that users assigned these roles can perform the necessary tasks and operations relevant to their responsibilities.
The design of Snowflake's role-based access control (RBAC) model ensures that system-defined roles have a specific set of non-revocable privileges to maintain the security, integrity, and operational efficiency of the Snowflake environment. This approach prevents accidental or intentional modification of privileges that could disrupt the essential functions or compromise the security of the Snowflake account.

If a Snowflake user decides a table should be clustered, what should be used as the cluster key?
- A. The columns most actively used in the select filters.
- B. The columns with many different values.
- C. The columns with very high cardinality.
- D. The columns that are queried in the select clause.
Answer: A

- A. SHARE on databases and schemas
- B. SELECT on tables used by the secure view
- C. REFERENCE_USAGE on databases
- D. CREATE_SHARE on the account

NEW QUESTION # 188
Which data types optimally store semi-structured data? (Select TWO).
- A. ARRAY
- B. STRING
- C. VARCHAR
- D. VARIANT
- E. CHARACTER
Answer: A,D
Explanation:
In Snowflake, semi-structured data is optimally stored using specific data types that are designed to handle the flexibility and complexity of such data. The VARIANT data type can store structured and semi-structured data types, including JSON, Avro, ORC, Parquet, or XML, in a single column. The ARRAY data type, on the other hand, is suitable for storing ordered sequences of elements, which can be particularly useful for semi-structured data types like JSON arrays. These data types provide the necessary flexibility to store and query semi-structured data efficiently in Snowflake.

Snowflake Documentation: Semi-structured Data Types

NEW QUESTION # 190
What feature can be used to reorganize a very large table on one or more columns?
- A. Clustering keys
- B. Key partitions
- C. Micro-partitions
- D. Clustered partitions
Answer: A
Explanation:
Clustering keys in Snowflake are used to reorganize large tables based on one or more columns. This feature optimizes the arrangement of data within micro-partitions to improve query performance, especially for large tables where efficient data retrieval is crucial.

NEW QUESTION # 195
A clustering key was defined on a table, but It is no longer needed. How can the key be removed?
- A. ALTER TABLE <TABLE NAME> DELETE CLUSTERING KEY
- B. ALTER TABLE <TABLE NAME> DROP CLUSTERING KEY
- C. ALTER TABLE <TABLE NAME> REMOVE CLUSTERING KEY
- D. ALTER TABLE <TABLE NAME> PURGE CLUSTERING KEY
Answer: B
Explanation:
To remove a clustering key that was previously defined on a table in Snowflake, the correct SQL command is ALTER TABLE <TABLE NAME> DROP CLUSTERING KEY. This command removes the existing clustering key from the table, after which Snowflake will no longer re-cluster data based on that key during maintenance operations or after data loading operations.

* Example Syntax:
sql
CopyEdit
COPY INTO 's3://mybucket/mypath/'
FROM my_table
STORAGE_INTEGRATION = my_s3_integration;
* This command exports data from Snowflake tables into external storage like AWS S3, Azure Blob Storage, or Google Cloud Storage.

NEW QUESTION # 198
User1, who has the SYSADMIN role, executed a query on Snowsight. User2, who is in the same Snowflake account, wants to view the result set of the query executed by User1 using the Snowsight query history.
What will happen if User2 tries to access the query history?
- A. User2 will be unable to view the result set of the query executed by User1.
- B. If User2 has the ACCOUNTADMIN role they will be able to see the results.
- C. If User2 has the sysadmin role they will be able to see the results.
- D. If User2 has the securityadmin role they will be able to see the results.
Answer: B
Explanation:
In Snowflake, the query history and the results of queries executed by a user are accessible based on the roles and permissions. If User1 executed a query with the SYSADMIN role, User2 would be able to view the result set of that query executed by User1 only if User2 has the ACCOUNTADMIN role. The ACCOUNTADMIN role has the broadest set of privileges, including the ability to access all aspects of the account's operation, data, and query history, thus enabling User2 to view the results of queries executed by other users.

NEW QUESTION # 199
How would you determine the size of the virtual warehouse used for a task?
- A. Root task may be executed concurrently (i.e. multiple instances), it is recommended to leave some margins in the execution window to avoid missing instances of execution
- B. Querying (select) the size of the stream content would help determine the warehouse size. For example, if querying large stream content, use a larger warehouse size
- C. If using the stored procedure to execute multiple SQL statements, it's best to test run the stored procedure separately to size the compute resource first
- D. Since task infrastructure is based on running the task body on schedule, it's recommended to configure the virtual warehouse for automatic concurrency handling using Multi-cluster warehouse (MCW) to match the task schedule
Answer: C
NEW QUESTION # 200
