NEW QUESTION # 170
Which query contains a Snowflake hosted file URL in a directory table for a stage named bronzestage?
- A. select * from directory(@bronzestage);
- B. list @bronzestage;
- C. select * from table(information_schema.stage_directory_file_registration_history( stage name=>'bronzestage1));
- D. select metadata$filename from @bronzestage;
Answer: A
Explanation:
Explanation
According to the Snowflake documentation , a directory table stores a catalog of staged files in cloud storage and can be queried to retrieve the Snowflake-hosted file URL to each file in the stage. A file URL has the following format:
https://<account_identifier>/api/files/<db_name>.<schema_name>.<stage_name>/<relative_path> Based on this information, I think the query that contains a Snowflake hosted file URL in a directory table for a stage named bronzestage is B. select * from directory(@bronzestage);

What can be used to process unstructured data?
- A. Snowpipe
- B. External tables
- C. The copy into <table> command
- D. External functions
Answer: D
Explanation:
To process unstructured data in Snowflake, external functions can be used.
* External Functions: These allow you to call external services and processing engines from within Snowflake SQL. External functions can be used to handle complex processing tasks that are not natively supported by Snowflake, including those involving unstructured data.
* Implementation: You define an external function in Snowflake that points to an external processing service (e.g., AWS Lambda, Google Cloud Functions).

* Snowflake Documentation on External Functions

What persistent data structures are used by the search optimization service to improve the performance of point lookups?
- A. Equality searches
- B. Search access paths
- C. Micro-partitions
- D. Clustering keys
Answer: B
Explanation:
The search optimization service in Snowflake uses persistent data structures known as search access paths to improve the performance of point lookups. These structures enable efficient retrieval of data by reducing the amount of data scanned during queries.
* Search Access Paths:
* Search access paths are special indexing structures maintained by the search optimization service.
* They store metadata about the distribution of data within tables, enabling faster lookups for specific values.
* Point Lookups:
* Point lookups involve searching for a specific value within a column.
* By leveraging search access paths, Snowflake can quickly locate the exact micro-partition containing the value, minimizing the amount of data scanned.
* Performance Improvement:
* The use of search access paths significantly reduces query execution time for point lookups.
* This is especially beneficial for large tables where scanning all micro-partitions would be computationally expensive.

* Snowflake Documentation: Search Optimization Service
* Snowflake Documentation: Understanding Search Access Paths
NEW QUESTION # 179
Which of the following are characteristics of Snowflake virtual warehouses? (Choose two.)
- A. A user cannot specify a default warehouse when using the ODBC driver.

- D. The default virtual warehouse size can be changed at any time.
- E. Auto-resume applies only to the last warehouse that was started in a multi-cluster warehouse.

How can a user change which columns are referenced in a view?
- A. Modify the columns in the underlying table
- B. Use the ALTER VIEW command to update the view
- C. Recreate the view with the required changes
- D. Materialize the view to perform the changes
Answer: C
Explanation:
In Snowflake, to change the columns referenced in a view, the view must be recreated with the required changes. The ALTER VIEW command does not allow changing the definition of a view; it can only be used to rename a view, convert it to or from a secure view, or add, overwrite, or remove a comment for a view. Therefore, the correct approach is to drop the existing view and create a new one with the desired column references.
