Snowflake SnowPro® Core Certification 2026 Exam (COF-C03) 認定 COF-C03 試験問題 (Q1134-Q1139):

質問 # 1134
What is a key difference between JSON and CSV file formats when loading data? Select TWO.

A. JSON can be loaded into a VARIANT column without predefined schema
B. CSV files automatically detect and apply data types during loading
C. CSV stores flat, tabular data
D. CSV supports complex data types such as arrays and objects
E. JSON must be converted to CSV before it can be queried

正解：A、C

解説：
The correct answers are A. CSV stores flat, tabular data and E. JSON can be loaded into a VARIANT column without predefined schema .
Important correction:
The provided answer A, B is not correct. CSV does not natively support complex semi-structured data types such as arrays and objects. JSON does.
Why A is correct:
CSV is a delimited, flat file format commonly used for structured, tabular data. Each row usually represents a record, and each field is separated by a delimiter such as a comma.
Why E is correct:
JSON is semi-structured data and can be loaded into a Snowflake VARIANT column. This allows Snowflake to store JSON objects and arrays without requiring every nested field to be predefined as a relational column.
Example:
CREATE TABLE json_data (
src VARIANT
);
COPY INTO json_data
FROM @my_stage
FILE_FORMAT = (TYPE = JSON);
Why the other options are incorrect:
B). CSV does not natively support arrays and objects. JSON supports nested structures such as arrays and objects.
C). JSON does not need to be converted to CSV before it can be queried in Snowflake. Snowflake can query JSON data stored in VARIANT, OBJECT, or ARRAY columns.
D). CSV files do not automatically detect and apply Snowflake table data types during loading. The target table schema and file format options control how data is interpreted.
Official Snowflake documentation reference:
Snowflake documentation explains that CSV is used for structured data, while semi-structured formats such as JSON can be loaded into VARIANT columns and queried using semi-structured data syntax.
Reference: Snowflake Documentation - Semi-structured data; Snowflake Documentation - Loading JSON data; Snowflake Documentation - CSV file format options; SnowPro Core Study Guide - Data Loading and Unloading.

質問 # 1135
A user is loading JSON documents composed of a huge array containing multiple records into Snowflake.
The user enables the strip__outer_array file format option
What does the STRIP_OUTER_ARRAY file format do?

A. It removes the outer array structure and loads the records into separate table rows,
B. It removes the last element of the outer array.
C. It removes the NULL elements from the JSON object eliminating invalid data and enables the ability to load the records
D. It removes the trailing spaces in the last element of the outer array and loads the records into separate table columns

正解：A

解説：
The STRIP_OUTER_ARRAY file format option in Snowflake is used when loading JSON documents that are composed of a large array containing multiple records. When this option is enabled, it removes the outer array structure, which allows each record within the array to be loaded as a separate row in the table. This is particularly useful for efficiently loading JSON data that is structured as an array of records1.

質問 # 1136
Network policies can be applied to which of the following Snowflake objects? (Choose two.)

A. Accounts
B. Users
C. Warehouses
D. Databases
E. Roles

正解：A、B

解説：
Network policies in Snowflake can be applied to users and accounts.These policies control inbound access to the Snowflake service and internal stages, allowing or denying access based on the originating network identifiers12.

質問 # 1137
Which file function gives a user or application access to download unstructured data from a Snowflake stage?

A. GET_PRESIGNED_URL
B. BUILD_STAGE_FILE_URL
C. BUILD_SCOPED_FILE_URL
D. GET STAGE LOCATION

正解：A

解説：
The function that provides access to download unstructured data from a Snowflake stage is:
C . GET_PRESIGNED_URL: This function generates a presigned URL for a single file within a stage. The generated URL can be used to directly access or download the file without needing to go through Snowflake. This is particularly useful for unstructured data such as images, videos, or large text files, where direct access via a URL is needed outside of the Snowflake environment.
Example usage:
SELECT GET_PRESIGNED_URL('stage_name', 'file_path');
This function simplifies the process of securely sharing or accessing files stored in Snowflake stages with external systems or users.

質問 # 1138
Which of the following features, associated with Continuous Data Protection (CDP), require additional Snowflake-provided data storage? (Choose two.)

A. Time Travel
B. Tri-Secret Secure
C. External stages
D. Data encryption
E. Fail-safe

正解：A、E

解説：
The features associated with Continuous Data Protection (CDP) that require additional Snowflake-provided data storage are Time Travel and Fail-safe. Time Travel allows users to access historical data within a defined period, while Fail-safe provides an additional layer of data protection beyond the Time Travel period.
