NEW QUESTION # 1163
Which of the following statements apply to Snowflake in terms of security? (Choose two.)
Answer: B,C
Explanation:
Snowflake uses a Role-Based Access Control (RBAC) model to manage access to data and resources.
Additionally, Snowflake ensures that all data is encrypted, both at rest and in transit, to provide a high level of security for data stored within the platform. References: [ COF-C03 ] SnowPro Core Certification Exam Study Guide
NEW QUESTION # 1164
What type of query will benefit from the query acceleration service?
Answer: A
Explanation:
The query acceleration service in Snowflake is designed to benefit queries that involve large scans and selective filters.This service can offload portions of the query processing work to shared compute resources, which can handle these types of workloads more efficiently by performing more work in parallel and reducing the wall-clock time spent in scanning and filtering2.References:[COF-C02] SnowPro Core Certification Exam Study Guide
NEW QUESTION # 1165
If a column contains float values that are greater than (15,9) and the values need to be preserved when unloading data, what data file format should be used?
Answer: D
Explanation:
The correct answer is A. JSON .
When unloading floating-point or high-precision numeric values, users must consider whether the target file format can preserve the values as needed. JSON stores values in a textual semi-structured representation and can preserve numeric values without forcing them into a fixed Parquet numeric precision representation.
Why A is correct:
For values that exceed a precision/scale such as (15,9) and must be preserved during unloading, JSON is the safest option among the listed choices because it can represent the values textually in the output.
Why the other options are incorrect:
B). PARQUET has limitations for certain numeric precision/scale representations during unload. Snowflake documentation notes precision-related considerations for Parquet unloads.
C). AVRO is a semi-structured file format, but it is not the best documented answer for preserving float values beyond this precision scenario.
D). ORC is not the best answer for this Snowflake unload precision scenario.
Official Snowflake documentation reference:
Snowflake documentation for unloading data explains that file format choice can affect how numeric values are represented and preserved. JSON is commonly used when preserving semi-structured or text-based representations is required.

NEW QUESTION # 1166
A global company needs to share financial reports with managers who are in different regions. Managers should only see the data from their respective regions. How can these requirements be met with the least amount of operational overhead?
Answer: C
Explanation:
The correct answer is C. Use row-level security on the source data table used to generate the reports .
The requirement is to let managers see only rows for their respective regions. This is a row-filtering requirement, so Snowflake row-level security is the best fit.
Why C is correct:
Row-level security in Snowflake is implemented using row access policies. A row access policy can dynamically filter table rows based on the current user, current role, or mapping table logic.
Example concept:
CREATE ROW ACCESS POLICY region_policy
AS (region STRING) RETURNS BOOLEAN - >
region IN (
SELECT allowed_region
FROM manager_region_map
WHERE manager_role = CURRENT_ROLE()
);
This allows one shared table or report to serve multiple managers while enforcing region-specific visibility.
Why the other options are incorrect:
A). Creating unique views for each region increases operational overhead as regions or access rules change.
B). Building individual reports for each manager creates the highest operational overhead and is difficult to maintain.
D). Dynamic Data Masking hides or transforms column values. It does not filter rows by region.
Official Snowflake documentation reference:
Snowflake documentation describes row access policies as schema-level objects that determine whether a row is visible in a query result. They are used to implement row-level security.
Reference: Snowflake Documentation - Row access policies; Snowflake Documentation - Dynamic Data Masking; SnowPro Core Study Guide - Data Protection and Governance.
NEW QUESTION # 1167
Which data types does Snowflake support when querying semi-structured data? (Select TWO)
Answer: A,E
Explanation:
Snowflake supports querying semi-structured data using specific data types that are capable of handling the flexibility and structure of such data. The data types supported for this purpose are:
A . VARIANT: This is a universal data type that can store values of any other type, including structured and semi-structured types.It is particularly useful for handling JSON, Avro, ORC, Parquet, and XML data formats1.
B . ARRAY: An array is a list of elements that can be of any data type, including VARIANT, and is used to handle semi-structured data that is naturally represented as a list1.
These data types are part of Snowflake's built-in support for semi-structured data, allowing for the storage, querying, and analysis of data that does not fit into the traditional row-column format.
