Snowflake SnowPro® Core Certification 2026 Exam (COF-C03) 認定 COF-C03 試験問題 (Q114-Q119):

質問 # 114
How can a Snowflake user optimize query performance in Snowflake? (Select TWO).

正解：A、B

解説：
To optimize query performance in Snowflake, users can cluster a table, which organizes the data in a way that minimizes the amount of data scanned during queries.Additionally, enabling the search optimization service can improve the performance of selective point lookup queries on large tables34.


質問 # 115
What is SnowSQL used for?

正解：C

解説：
The correct answer is B. Loading and unloading data .
SnowSQL is Snowflake's command-line client. It is used to connect to Snowflake, execute SQL statements, run SQL scripts, and perform data loading and unloading operations.
Why B is correct:
SnowSQL supports data loading and unloading workflows. For example, users can use SnowSQL to run PUT, GET, and COPY commands.
Example loading workflow:
PUT file:///local/path/data.csv @my_stage;
COPY INTO my_table
FROM @my_stage
FILE_FORMAT = (TYPE = CSV);
Example unloading workflow:
COPY INTO @my_stage/output/
FROM my_table;
GET @my_stage/output/ file:///local/path/output/;
Why the other options are incorrect:
A). Dashboards are usually developed in BI tools or applications, not SnowSQL.
C). Snowflake Native Apps are developed and managed using Snowflake Native App Framework tools and Snowflake CLI, not primarily SnowSQL.
D). Monitoring transformation activity is usually done through Snowflake views, query history, task history, event tables, or monitoring features, not as the primary purpose of SnowSQL.
Official Snowflake documentation reference:
Snowflake documentation describes SnowSQL as the command-line client for connecting to Snowflake and executing SQL queries, including data loading and unloading commands.
Reference: Snowflake Documentation - SnowSQL; Snowflake Documentation - Loading data using SnowSQL; Snowflake Documentation - PUT, GET, and COPY INTO; SnowPro Core Study Guide - Data Loading and Unloading.

質問 # 116
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?

正解：D

解説：
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.

質問 # 117
What is the MINIMUM edition of Snowflake that is required to use a SCIM security integration?

正解：C

解説：
The minimum edition of Snowflake required to use a SCIM security integration is the Enterprise Edition.
SCIM integrations are used for automated management of user identities and groups, and this feature is available starting from the Enterprise Edition of Snowflake. References: [ COF-C03 ] SnowPro Core Certification Exam Study Guide


質問 # 118
What consideration should be made when loading data into Snowflake?

正解：C

解説：
When loading data into Snowflake, one critical consideration is the parallel processing capability of the virtual warehouse used for the data loading operation. The number of data files that can be processed in parallel during a loading operation is determined by the size and resources of the virtual warehouse. A larger warehouse can process more files simultaneously, improving the efficiency and speed of data loading operations. Optimizing the size of the virtual warehouse according to the data loading needs and the size and number of files to be loaded can significantly impact the overall performance of the data loading process.
