NEW QUESTION # 649
In Snowflake's data security framework, how does column-level security contribute to the protection of sensitive information? (Select TWO).

A. Column-level security supports encryption of the entire database.
B. Column-level security allows the application of a masking policy to a column within a table or view.
C. Column-level security ensures that only the table owner can access the data.
D. Implementation of column-level security will optimize query performance.
E. Column-level security limits access to specific columns within a table based on user privileges

Answer: B,E

Explanation:
Column-level security in Snowflake enhances data protection by restricting access and applying masking policies to sensitive data at the column level.
* Limiting Access Based on User Privileges:
* Column-level security allows administrators to define which users or roles have access to specific columns within a table.
* This ensures that sensitive data is only accessible to authorized personnel, thereby reducing the risk of data breaches.
* Application of Masking Policies:
* Masking policies can be applied to columns to obfuscate sensitive data.
* For example, credit card numbers can be masked to show only the last four digits, protecting the full number from being exposed.

NEW QUESTION # 650
What impact does dropping a column from a table have on the micro-partitions of that table?

A. The current micro-partitions will not be available for Time Travel, and new micro-partitions will be created.
B. New micro-partitions will be created containing only the data for the remaining columns.
C. The existing micro-partitions will not be affected.
D. The data associated with the dropped column will be removed from all existing micro-partitions.

Answer: C

NEW QUESTION # 651
A virtual warehouse has the same value for MIN_CLUSTER_COUNT and MAX_CLUSTER_COUNT. What will happen when the warehouse is started?

A. Snowflake will start a single cluster and will start additional clusters as soon as queries are in the queue for more than 6 minutes.
B. Snowflake will start all available clusters.
C. Snowflake will start a single cluster and will start an additional cluster once it estimates there is enough query load to keep the new cluster running for 6 minutes.
D. Snowflake will start enough clusters to handle the current workload.

Answer: B

Explanation:
The correct answer is A. Snowflake will start all available clusters .
A multi-cluster warehouse can run in Auto-scale mode or Maximized mode. When MIN_CLUSTER_COUNT and MAX_CLUSTER_COUNT are set to the same value greater than 1, the warehouse runs in Maximized mode.
Why A is correct:
In Maximized mode, Snowflake starts all configured clusters when the warehouse starts. For example, if both MIN_CLUSTER_COUNT and MAX_CLUSTER_COUNT are set to 3, Snowflake starts 3 clusters when the warehouse starts.
Clarification:
"Available clusters" here means all clusters configured for that warehouse, not every cluster in the Snowflake account.
Why the other options are incorrect:
B). Starting enough clusters based on workload describes Auto-scale behavior, not Maximized mode.
C). This describes a queued-query scaling behavior but does not apply when minimum and maximum cluster counts are equal.
D). This describes the Economy scaling policy behavior in Auto-scale mode, not Maximized mode.
Official Snowflake documentation reference:
Snowflake documentation explains that when the minimum and maximum number of clusters are the same, a multi-cluster warehouse runs in Maximized mode and starts all clusters when the warehouse starts.
Reference: Snowflake Documentation - Multi-cluster warehouses; Snowflake Documentation - Maximized mode; SnowPro Core Study Guide - Snowflake Account and Resource Management.
