NEW QUESTION # 1064
A size Small standard virtual warehouse running in auto-suspend mode is used for a production Business Intelligence (BI) reporting environment. The BI reports generate quickly in the early morning, but as the day progresses and there are more users, it takes longer to run the reports. How can this situation be addressed?
Answer: C
NEW QUESTION # 1065
Which Snowflake table type is only visible to the user who creates it, can have the same name as permanent tables in the same schema, and is dropped at the end of the session?
Answer: C
Explanation:
In Snowflake, a Temporary table is a type of table that is only visible to the user who creates it, can have the same name as permanent tables in the same schema, and is automatically dropped at the end of the session in which it was created. Temporary tables are designed for transient data processing needs, where data is needed for the duration of a specific task or session but not beyond. Since they are automatically cleaned up at the end of the session, they help manage storage usage efficiently and ensure that sensitive data is not inadvertently persisted.

NEW QUESTION # 1066
By default, which role can create resource monitors?
Answer: C
Explanation:
The role that can by default create resource monitors in Snowflake is the ACCOUNTADMIN role. Resource monitors are a crucial feature in Snowflake that allows administrators to track and control the consumption of compute resources, ensuring that usage stays within specified limits. The creation and management of resource monitors involve defining thresholds for credits usage, setting up notifications, and specifying actions to be taken when certain thresholds are exceeded.
Given the significant impact that resource monitors can have on the operational aspects and billing of a Snowflake account, the capability to create and manage them is restricted to the ACCOUNTADMIN role. This role has the broadest set of privileges in Snowflake, including the ability to manage all aspects of the account, such as users, roles, warehouses, databases, and resource monitors, among others.

NEW QUESTION # 1067
In the ACCOUNT_USAGE schema, what system-defined database role can see a list of tables?
Answer: C
Explanation:
The correct answer is A. OBJECT_VIEWER.
Snowflake provides system-defined database roles for the shared SNOWFLAKE database. These roles allow users to access different categories of metadata and usage information in schemas such as ACCOUNT_USAGE.
The OBJECT_VIEWER database role is used to view object metadata. This includes metadata about databases, schemas, tables, views, and other Snowflake objects.
Why A is correct:
The ACCOUNT_USAGE.TABLES view contains information about tables in the account. Access to object metadata, including lists of tables, is associated with the OBJECT_VIEWER database role.
Why the other options are incorrect:
B). USAGE_VIEWER is used for usage and billing-related information, such as metering and warehouse usage, not object lists.
C). GOVERNANCE_VIEWER is used for governance-related metadata, such as tags, masking policies, and related governance features.
D). SECURITY_VIEWER is used for security-related metadata, such as users, roles, grants, and access history information.
Official Snowflake documentation reference:
Snowflake documentation describes system-defined database roles in the shared SNOWFLAKE database. The OBJECT_VIEWER role provides access to object metadata views in ACCOUNT_USAGE, including tables.
Reference: Snowflake Documentation - SNOWFLAKE database roles; Snowflake Documentation - ACCOUNT_USAGE.TABLES view; SnowPro Core Study Guide - Snowflake Account and Resource Management.
