NEW QUESTION # 636
Which Snowflake objects can be restored using Time Travel? (Select VNO).

Answer: B,D

Explanation:
Snowflake's Time Travel feature allows users to access historical data within a specific period. This feature supports the restoration of various objects, including databases and schemas, to their previous states. Time Travel can be used for recovering dropped objects, undoing accidental changes, or analyzing data changes over time. However, it does not support user or role objects like Users and Roles, or compute resources like Virtual Warehouses.References: Snowflake Documentation on Time Travel

NEW QUESTION # 638
In Snowflake's data security framework, how does column-level security contribute to the protection of sensitive information? (Select TWO).

Answer: A,D

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 # 639
Which service or feature in Snowflake is used to improve the performance of certain types of lookup and analytical queries that use an extensive set of WHERE conditions?

Answer: A

Explanation:
The Search Optimization Service in Snowflake is designed to improve the performance of specific types of queries, particularly those involving extensive sets of WHERE conditions. By maintaining a search index on tables, this service can accelerate lookup and analytical queries, making it a valuable feature for optimizing query performance and reducing execution times for complex searches.

Snowflake Documentation: Search Optimization Service


NEW QUESTION # 640
Which function is used to retrieve the filename for a file stored on a stage?

Answer: D

Explanation:
The correct answer is A. GET_RELATIVE_PATH .
The GET_RELATIVE_PATH function is used to return the relative path of a staged file. The relative path identifies the file name and path of the file within the stage.
Why A is correct:
A file stored in a stage can be referenced by its relative path. GET_RELATIVE_PATH retrieves that relative path, which includes the file name.
Why the other options are incorrect:
B). GET_STAGE_LOCATION returns the URL or location of a stage, not the filename of a specific staged file.
C). BUILD_STAGE_FILE_URL creates a URL for accessing a staged file, but it is not used simply to retrieve the filename.
D). GET_OBJECT_REFERENCES is related to object references, not staged file names.
Official Snowflake documentation reference:
Snowflake documentation describes GET_RELATIVE_PATH as a function that returns the relative path for a staged file.
Reference: Snowflake Documentation - File functions; Snowflake Documentation - GET_RELATIVE_PATH; SnowPro Core Study Guide - Data Loading and Unloading.
