NEW QUESTION # 356
When using the COPY INTO < table > command, which parameter should be used to load unstructured data?
Answer: B
Explanation:
The FILE_PROCESSOR copy option is used when COPY INTO < table > processes unstructured files through a custom file processor. Snowflake's CUSTOM file-format type identifies a stage as containing unstructured data and is valid only with the FILE_PROCESSOR option. FORCE controls whether files already recorded as loaded are loaded again. LOAD_UNCERTAIN_FILES determines whether files whose load status is uncertain are processed, and LOAD_MODE controls how supported structured-data loading behavior is applied; neither selects an unstructured-file processor. Therefore, FILE_PROCESSOR is the correct parameter. In practice, the processor configuration determines how file content and metadata are transformed into rows and columns in the target table, while the COPY statement handles the staged-file ingestion workflow.
NEW QUESTION # 357
Which service is designed to process unstructured data and put it into tables?
Answer: D
Explanation:
The correct answer is D. Document AI .
Document AI is a Snowflake Cortex feature designed to extract information from unstructured documents and make that information usable in structured form, such as rows and columns in Snowflake tables.
Why D is correct:
Document AI processes documents such as PDFs or forms and extracts values from them. The extracted data can then be stored in Snowflake tables for querying, analytics, and downstream processing.
Why the other options are incorrect:
A). Cortex Analyst enables natural language questions over structured data using semantic models. It is not the primary service for extracting data from documents into tables.
B). Cortex Search provides search over text and unstructured/semi-structured data, but it is not the main service for document extraction into tables.
C). Snowflake Copilot assists users with SQL and Snowflake workflows, but it is not the service specifically designed to process documents into table data.
Official Snowflake documentation reference:
Snowflake documentation describes Document AI as a Snowflake Cortex feature that uses AI to extract data from documents and process unstructured data for use in Snowflake.

NEW QUESTION # 358
Which Query Profile metrics will provide information that can be used to improve query performance?
(Select TWO).
Answer: A,E
Explanation:
Two key metrics in Snowflake'sQuery Profilethat provide insights for performance improvement are:
Remote Disk IO: This measures the time the query spends waiting on remote disk access, indicating potential performance issues related to I/O bottlenecks.
Pruning: This metric reflects how effectively Snowflake's micro-partition pruning is reducing the data scanned. Better pruning (more partitions excluded) leads to faster query performance, as fewer micro- partitions need to be processed.
These metrics are essential for identifying and addressing inefficiencies in data retrieval and storage access, optimizing overall query performance.
NEW QUESTION # 359
What are the correct parameters for time travel and fail-safe in the Snowflake Enterprise Edition?
Answer: A
Explanation:
In the Snowflake Enterprise Edition, the default Time Travel retention is set to 1 day, the maximum Time Travel retention can be set up to 90 days, and the Fail-safe retention timeis 7 days3.
NEW QUESTION # 360
What is the MINIMUM size of a table for which Snowflake recommends considering adding a clustering key?
Answer: C
Explanation:
Snowflake recommends considering adding a clustering key to a table when its size reaches1 Terabyte (TB)or larger. Clustering keys help optimize the storage and query performance by organizing the data in a table based on the specified columns. This is particularly beneficial for large tables where data retrieval can become inefficient without proper clustering.
Why Clustering Keys Are Important:Clustering keys ensure that data stored in Snowflake is physically ordered in a way that aligns with the most frequent access patterns, thereby reducing the amount of scanned data during queries and improving performance.
Recommendation Basis:The recommendation for tables of size 1 TB or larger is based on the observation that smaller tables generally do not benefit as much from clustering, given Snowflake ' s architecture. However, as tables grow in size, the benefits of clustering become more pronounced.
Implementing Clustering Keys:
To set a clustering key for a table, you can use theCLUSTER BYclause during table creation or alter an existing table to add it:
CREATETABLEmy_table (... ) CLUSTERBY(column1, column2);
Or for an existing table:
ALTERTABLEmy_table CLUSTERBY(column1, column2);
Reference:For additional information on clustering in Snowflake and recommendations on when to use clustering keys, consult the Snowflake documentation on managing and optimizing data clustering:
