Snowflake SnowPro® Core Certification 2026 Exam (COF-C03) 認定 COF-C03 試験問題 (Q778-Q783):

質問 # 778
Which function, when combined with an INSERT statement, will insert semi-structured data into a VARIANT column?

A. TO_JSON
B. TO_VARCHAR
C. OBJECT_INSERT
D. PARSE_JSON

正解：D

解説：
The correct answer is C. PARSE_JSON .
PARSE_JSON parses a valid JSON-formatted string and returns a VARIANT value. This is commonly used when inserting semi-structured JSON data into a VARIANT column.
Why C is correct:
A VARIANT column can store semi-structured data such as JSON objects and arrays. When the source value is a JSON string, PARSE_JSON converts it into a Snowflake VARIANT.
Example:
CREATE TABLE json_table (
src VARIANT
);
INSERT INTO json_table
SELECT PARSE_JSON( ' { " customer_id " : 101, " region " : " WEST " } ' ); Why the other options are incorrect:
A). TO_JSON converts a VARIANT value into a JSON string. It is commonly used in the opposite direction.
B). TO_VARCHAR converts a value to a string, not to a semi-structured VARIANT.
D). OBJECT_INSERT inserts or updates a key-value pair inside an existing object, but it is not the primary function used to parse JSON text into a VARIANT column.
Official Snowflake documentation reference:
Snowflake documentation describes PARSE_JSON as a function that interprets an input string as JSON and returns a VARIANT value.
Reference: Snowflake Documentation - PARSE_JSON; Snowflake Documentation - Semi-structured data types; SnowPro Core Study Guide - Working with Semi-Structured Data.

質問 # 779
What privileges are required to allow role RL_CUST_WH to start warehouse CUST_WH?

A. GRANT CREATE WAREHOUSES ON ACCOUNT TO ROLE RL_CUST_WH;
B. GRANT USAGE ON CUST_WH TO ROLE RL_CUST_WH;
C. GRANT MANAGE WAREHOUSES ON ACCOUNT TO ROLE RL_CUST_WH;
D. GRANT OPERATE ON CUST_WH TO ROLE RL_CUST_WH;

正解：D

解説：
To start, resume, or suspend a warehouse, the role needs the OPERATE privilege. USAGE only allows reference to the object but not its activation.
Required Privileges for Starting a Warehouse:
* USAGE (to reference)
* OPERATE (to start/stop)
Reference:
Snowflake Docs: Warehouse Privileges

質問 # 780
How does an authentication policy affect security in a Snowflake account?

A. It controls how a client or user can access Snowflake.
B. It restricts inbound access to Snowflake data.
C. It restricts outbound traffic from Snowflake to external network destinations.
D. It provides users with the ability to use Single Sign-On, or SSO, to access Snowflake.

正解：A

解説：
The correct answer is A. It controls how a client or user can access Snowflake .
An authentication policy controls authentication behavior for users or accounts. It determines which authentication methods are allowed and can be used to enforce security requirements for access to Snowflake.
Why A is correct:
Authentication policies control how users or clients authenticate to Snowflake. They can be used to allow or restrict authentication methods, helping organizations enforce secure access standards.
Why the other options are incorrect:
B). Restricting inbound access to Snowflake is handled by network policies, not authentication policies.
C). Restricting outbound traffic from Snowflake to external network destinations is handled by external access integrations and network rules, not authentication policies.
D). SSO can be part of an authentication strategy, but an authentication policy is broader than only enabling SSO.
Official Snowflake documentation reference:
Snowflake documentation describes authentication policies as security objects that control authentication methods for users in a Snowflake account.
Reference: Snowflake Documentation - Authentication policies; Snowflake Documentation - Network policies; SnowPro Core Study Guide - Security and Access Control.

質問 # 781
What criteria does Snowflake use to determine the current role when initiating a session? (Select TWO).

A. If a role was specified as part of the connection and that role has been granted to the Snowflake user, the specified role becomes the current role.
B. If a role was specified as part of the connection and that role has not been granted to the Snowflake user, the role is automatically granted and it becomes the current role.
C. If no role was specified as part of the connection and a default role has been defined for the Snowflake user, that role becomes the current role.
D. If a role was specified as part of the connection and that role has not been granted to the Snowflake user, it will be ignored and the default role will become the current role.
E. If no role was specified as part of the connection and a default role has not been set for the Snowflake user, the session will not be initiated and the log in will fail.

正解：A、C

解説：
When initiating a session in Snowflake, the system determines the current role based on the user's connection details and role assignments. If a user specifies a role during the connection, and that role is already granted to them, Snowflake sets it as the current role for the session. Alternatively, if no role is specified during the connection, but the user has a default role assigned, Snowflake will use this default role as the current session role. These mechanisms ensure that users operate within their permissions, enhancing security and governance within Snowflake environments.

質問 # 782
What do these Query Profile metrics indicate about the query micro-partition pruning?

A. No micro-partitions were pruned during execution.
B. The query used the local disk cache and pruning was not required.
C. Since the bytes scanned is less than the bytes written to results some pruning has occurred.
D. The size of the data queried was too small to trigger micro-partition pruning.

正解：D
