質問 # 367
What happens when a virtual warehouse is resized?
正解：C
解説：
When a virtual warehouse in Snowflake is resized, specifically when it is increased in size, the additional compute resources become immediately available to all running and queued queries. This means that the performance of these queries can improve due to the increased resources.Conversely, when the size of a warehouse is reduced, the compute resources are not removed until they are no longer being used by any current operations1.

質問 # 368
An external stage many_stage contains many directories including one, app_files that contains CSV files How can all the CSV files from this directory be moved into table my_table without scanning files that are not needed?
正解：B
質問 # 369
What objects in Snowflake are supported by Dynamic Data Masking? (Select TWO).'
正解：A、E
解説：
Dynamic Data Masking in Snowflake supports tables and views. These objects can have masking policies applied to their columns to dynamically mask data at query time3.
質問 # 370
Which table function should be used to view details on a Directed Acyclic Graphic (DAG) run that is presently scheduled or is executing?
正解：B
解説：
TheCURRENT_TASK_GRAPHStable function is designed to provide information on Directed Acyclic Graphs (DAGs) that are currently scheduled or executing within Snowflake. This function offers insights into the structure and status of task chains, enabling users to monitor and troubleshoot task executions. DAGs in Snowflake represent sequences of tasks with dependencies, and understanding their current state is crucial for managing complex workflows.

質問 # 371
What is the recommended use for the COPY INTO < location > SINGLE = TRUE command?
正解：A
解説：
The correct answer is D. To unload a single file from a table into a stage .
The COPY INTO < location > command is used to unload data from Snowflake to a stage. When the SINGLE = TRUE option is included, Snowflake attempts to unload the query or table result into a single output file instead of multiple files.
Why D is correct:
SINGLE = TRUE is specifically an unload option for COPY INTO < location > . It is useful when a downstream process expects one output file.
Example:
COPY INTO @my_stage/export/customers.csv
FROM customers
FILE_FORMAT = (TYPE = CSV)
SINGLE = TRUE;
Why the other options are incorrect:
A). Preventing duplicate loads is handled by Snowflake load metadata and the FORCE option, not SINGLE = TRUE.
B). Loading an individual file is done with COPY INTO < table > and a file path or the FILES option, not COPY INTO < location > SINGLE = TRUE.
C). "Parse the results into single stages" is not a Snowflake unload concept.
Official Snowflake documentation reference:
Snowflake documentation for COPY INTO < location > describes SINGLE as the option that specifies whether to generate a single file or multiple files when unloading data.
Reference: Snowflake Documentation - COPY INTO < location > ; Snowflake Documentation - Unloading data from Snowflake; SnowPro Core Study Guide - Data Loading and Unloading.
