Snowflake SnowPro Core Certification Exam 認定 COF-C02 試験問題 (Q527-Q532):

質問 # 527
Which statistics on a Query Profile reflect the efficiency of the query pruning? (Select TWO).

正解：A、C

解説：
In a Snowflake Query Profile, the statistics "Partitions scanned" and "Bytes scanned" reflect the efficiency of query pruning. Query pruning refers to the ability of the query engine to skip unnecessary data, thereby reducing the amount of data that needs to be processed. Efficient pruning results in fewer partitions and bytes being scanned, improving query performance.

質問 # 528
Which clients does Snowflake support Multi-Factor Authentication (MFA) token caching for? (Select TWO).

正解：C、E

解説：
Multi-Factor Authentication (MFA) token caching is typically supported for clients that maintain a persistent connection or session with Snowflake, such as the ODBC driver and Python connector, to reduce the need for repeated MFA challenges. References: Based on general security practices in cloud services as of 2021.


質問 # 529
Which Snowflake data type is used to store JSON key value pairs?

正解：C

解説：
The VARIANT data type in Snowflake is used to store JSON key-value pairs along with other semi-structured data formats like AVRO, BSON, and XML. The VARIANT data type allows for flexible and dynamic data structures within a single column, accommodating complex and nested data. This data type is crucial for handling semi-structured data in Snowflake, enabling users to perform SQL operations on JSON objects and arrays directly.

* Snowflake Documentation: Semi-structured Data Types


質問 # 530
In which scenarios would a user have to pay Cloud Services costs? (Select TWO).

正解：D、E

解説：
In Snowflake, Cloud Services costs are incurred when the Cloud Services usage exceeds 10% of the compute usage (measured in credits). Therefore, scenarios A and E would result in Cloud Services charges because the Cloud Services usage is more than 10% of the compute credits used.

質問 # 531
What is the !define < variable > = < value > command used for in SnowSQL?

正解：A

解説：
The correct answer is B. Assigns a value to a variable .
Corrected wording:
The original command was written as idefine < variable > = < value > . In SnowSQL, the correct command is:
!define < variable > = < value >
SnowSQL supports variables that can be defined and reused in SQL scripts or interactive sessions. The !
define command assigns a value to a variable.
Why B is correct:
!define < variable > = < value > creates or sets a SnowSQL variable to the specified value.
Example:
!define table_name=my_table
SELECT *
FROM & table_name;
In this example, table_name is assigned the value my_table, and the variable can then be referenced later in the script.
Why the other options are incorrect:
A). The variable name is part of the command syntax, but the purpose of the command is to assign a value to that variable.
C). Context is usually set with commands such as USE DATABASE, USE SCHEMA, USE WAREHOUSE, or SnowSQL connection options.
D). The command does not establish metrics.
Official Snowflake documentation reference:
Snowflake documentation for SnowSQL explains that !define is used to define variables for use in SnowSQL sessions or scripts.
Reference: Snowflake Documentation - SnowSQL variables; Snowflake Documentation - SnowSQL commands; SnowPro Core Study Guide - Snowflake Account and Resource Management.
