問題 #811
In which scenarios would a user have to pay Cloud Services costs? (Select TWO).
答案：A,E
解題說明：
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.

問題 #812
Which object can be shared from a database in an account with other Snowflake accounts using Secure Data Sharing?
答案：C
解題說明：
The correct answer is B. Iceberg table .
Snowflake Secure Data Sharing allows providers to share supported database objects with other Snowflake accounts. Supported objects include tables, secure views, secure materialized views, secure UDFs, and certain other supported table types. Snowflake-managed Iceberg tables can be shared in supported configurations.
Why B is correct:
An Iceberg table is a supported table object in Snowflake and can be shared using Secure Data Sharing, subject to Snowflake's supported Iceberg table sharing requirements.
Why the other options are incorrect:
A). Event tables are used to store logging and tracing event data. They are not the expected shareable object in this question.
C). Temporary tables exist only within the session that created them and cannot be shared with other accounts.
D). Stored procedures are not standard objects shared through Secure Data Sharing in the same way as tables and secure views.
Official Snowflake documentation reference:
Snowflake documentation lists supported objects for Secure Data Sharing and describes sharing supported table objects, including Iceberg tables where supported.
Reference: Snowflake Documentation - Secure Data Sharing; Shareable database objects; Iceberg tables; SnowPro Core Study Guide - Data Protection and Governance.

問題 #813
What can a Snowflake user do in the Admin area of Snowsight?
答案：A
解題說明：
In the Admin area of Snowsight, users can analyze query performance, manage Snowflake warehouses, set up and view details about resource monitors, manage users and roles, and administer Snowflake accounts in their organization2.
問題 #814
What type of function returns one value for each Invocation?
答案：D
解題說明：
Scalar functions in Snowflake (and SQL in general) are designed to return a single value for each invocation.
They operate on a single value and return a single result, making them suitable for a wide range of data transformations and calculations within queries.

問題 #815
By default, how long is the standard retention period for Time Travel across all Snowflake accounts?
答案：C
解題說明：
By default, the standard retention period for Time Travel in Snowflake is 1 day across all Snowflake accounts. Time Travel enables users to access historical data within this retention window, allowing for point-in-time data analysis and recovery. This feature is a significant aspect of Snowflake's data management capabilities, offering flexibility in handling data changes and accidental deletions.
