Snowflake SnowPro Core Certification Exam Sample Questions (Q621-Q626):

NEW QUESTION # 621
What is the MINIMUM size requirement when creating a Snowpark-optimized virtual warehouse?

Answer: D

Explanation:
When creating a Snowpark-optimized virtual warehouse in Snowflake, the minimum size requirement is Small. Snowpark is designed to handle data processing workloads efficiently, and the Small size ensures adequate resources for such tasks.
Virtual Warehouse Sizes:
Snowflake offers different sizes for virtual warehouses, ranging from X-Small to 6X-Large.
Each size corresponds to a specific level of compute resources.
Minimum Size Requirement for Snowpark:
A Small virtual warehouse is the minimum size required to optimize performance and resource allocation for Snowpark workloads.
This ensures that the warehouse has sufficient capacity to handle data processing and transformation tasks efficiently.

NEW QUESTION # 622
By default, which role is required to change the refresh frequency for an auto-fulfilled application package?

Answer: D

Explanation:
The correct answer is C. GLOBALORGADMIN .
Corrected typos:
The original options contain typing errors:
A). ACCOUNT AUXIN should be ACCOUNTADMIN
B). SYSAEMIN should be SYSADMIN
C). CLOBALORGADMIN should be GLOBALORGADMIN
D). HECURITYADMIH should be SECURITYADMIN
Auto-fulfillment is an organization-level capability related to Snowflake Native Apps and listings across regions or accounts. Because refresh frequency for auto-fulfilled application packages is managed at the organization/global level, the required role is GLOBALORGADMIN.
Why C is correct:
GLOBALORGADMIN is the organization-level administrative role used for managing organization-wide features. Changing the refresh frequency for an auto-fulfilled application package requires this higher-level administrative authority.
Why the other options are incorrect:
A). ACCOUNTADMIN is the highest administrative role within a Snowflake account, but auto-fulfillment refresh frequency is an organization-level setting.
B). SYSADMIN manages account objects such as warehouses, databases, schemas, and tables, but it does not manage organization-level auto-fulfillment settings by default.
D). SECURITYADMIN manages users, roles, and grants, but it is not the default role for managing auto- fulfillment refresh frequency.
Official Snowflake documentation reference:
Snowflake documentation for auto-fulfillment and organization-level administration identifies GLOBALORGADMIN as the role used for managing organization-level Snowflake features.
Reference: Snowflake Documentation - Auto-fulfillment; Snowflake Documentation - Organization roles; Snowflake Documentation - Snowflake Native Apps; SnowPro Core Study Guide - Snowflake Account and Resource Management.


NEW QUESTION # 623

NEW QUESTION # 624
Which Snowflake object is supported by both database replication and replication groups?

Explanation:
* Materialized Views are supported by both database replication and replication groups in Snowflake.
* Replication ensures that these views and their definitions are available across regions or accounts as part of database or group replication.
Why Other Options Are Incorrect:
* A. Pipes: Supported only in replication groups, not database replication.
* B. Users: Snowflake does not replicate user objects.
* C. Stages: Supported only in replication groups, not database replication.
References:
* Snowflake Replication Overview


NEW QUESTION # 625
In Snowflake's data security framework, how does column-level security contribute to the protection of sensitive information? (Select TWO).

Answer: A,B

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.
