질문 # 876
What are valid sub-clauses to the OVER clause for a window function? (Select TWO).
정답：B,C
설명：
Valid sub-clauses to theOVERclause for a window function in SQL are:
C). ORDER BY: This clause specifies the order in which the rows in a partition are processed by the window function. It is essential for functions that depend on the row order, such as ranking functions.
D). PARTITION BY: This clause divides the result set into partitions to which the window function is applied.
Each partition is processed independently of other partitions, making it crucial for functions that compute values across sets of rows that share common characteristics.
These clauses are fundamental to defining the scope and order of data over which the window function operates, enabling complex analytical computations within SQL queries.

질문 # 877
Which technical needs require Enterprise Edition? Select TWO.
정답：B,E
설명：
Enterprise Edition includes features such as multi-cluster warehouses and column-level security features.
Multi-cluster warehouses are used for high concurrency, and column-level security includes features such as masking policies.
Why the others are incorrect:
Network policies are available below Enterprise. Private connectivity and Tri-Secret Secure require Business Critical or higher, not merely Enterprise.
Reference: Snowflake Documentation - Snowflake editions; Multi-cluster warehouses; Column-level security.
질문 # 878
A Snowflake table that is loaded using a Kafka connector has a schema consisting of which two variant columns? (Select TWO).
정답：B,D
설명：
When using the Snowflake Kafka connector, the table schema includes two important variant columns:
RECORD_TIMESTAMP: This column stores the timestamp from the Kafka record, enabling time-based analysis of incoming data.
RECORDKEY: This captures the unique key of each Kafka message, useful for uniquely identifying records or managing deduplication.
These columns ensure that each message's metadata and key information are preserved, facilitating data analysis and real-time processing tasks in Snowflake.
질문 # 879
What activities can a user with the ORGADMIN role perform? (Select TWO).
정답：A,E
설명：
The ORGADMIN role in Snowflake is designed to manage organization-level activities. This role can perform several tasks that span across multiple accounts within the organization.
View Usage Information: The ORGADMIN role can view usage statistics and billing information for all accounts within the organization.
-- Example: Viewing usage information
SELECT *
FROM organization_usage_history;
Enable Database Replication: The ORGADMIN role has the authority to enable and manage database replication for accounts within the organization.
-- Example: Enabling database replication
ALTER DATABASE my_database ENABLE REPLICATION TO ACCOUNT other_account; References:
Snowflake Documentation: Organization Administration
Snowflake Documentation: Replication
질문 # 880
What is the MINIMUM role required to set the value for the parameter ENABLE_ACCOUNT_DATABASE_REPLICATION?
정답：D
설명：
The ENABLE_ACCOUNT_DATABASE_REPLICATION parameter is a critical setting in Snowflake that allows or restricts the replication of databases across Snowflake accounts. Given the significant impact of this parameter on data management and security, only the ACCOUNTADMIN role has the minimum required privileges to set or modify it. This ensures that only users with the highest level of access and responsibility within the Snowflake environment can control database replication settings, maintaining strict governance and security standards.References: Snowflake Documentation on Database Replication
