How can a Snowflake administrator determine which user has accessed a database object that contains sensitive information?
Review the granted privileges to the database object.
Review the row access policy for the database object.
Query the ACCESS_HlSTORY view in the ACCOUNT_USAGE schema.
Query the REPLICATION USAGE HISTORY view in the ORGANIZATION USAGE schema.
To determine which user has accessed a database object containing sensitive information, a Snowflake administrator can query the ACCESS_HISTORY view in the ACCOUNT_USAGE schema, which provides information about access to database objects3.
Who can activate and enforce a network policy for all users in a Snowflake account? (Select TWO).
A user with an USERADMIN or higher role
A user with a SECURITYADMIN or higher role
A role that has been granted the ATTACH POLICY privilege
A role that has the NETWORK_POLlCY account parameter set
A role that has the ownership of the network policy
In Snowflake, a user with the SECURITYADMIN role or higher can activate and enforce a network policy for all users in an account. Additionally, a role that has ownership of the network policy can also activate and enforce it
Which Snowflake view is used to support compliance auditing?
ACCESS_HISTORY
COPY_HISTORY
QUERY_HISTORY
ROW ACCESS POLICIES
The ACCESS_HISTORY view in Snowflake is utilized to support compliance auditing. It provides detailed information on data access within Snowflake, including reads and writes by user queries. This view is essential for regulatory compliance auditing as it offers insights into the usage of tables and columns, and maintains a direct link between the user, the query, and the accessed data1.

Which solution improves the performance of point lookup queries that return a small number of rows from large tables using highly selective filters?
Automatic clustering
Materialized views
Query acceleration service
Search optimization service
The search optimization service improves the performance of point lookup queries on large tables by using selective filters to quickly return a small number of rows. It creates an optimized data structure that helps in pruning the micro-partitions that do not contain the queried values3. References: [COF-C02] SnowPro Core Certification Exam Study Guide
At what level is the MIN_DATA_RETENTION_TIME_IN_DAYS parameter set?
Account
Database
Schema
Table
The MIN_DATA_RETENTION_TIME_IN_DAYS parameter is set at the account level. This parameter determines the minimum number of days Snowflake retains historical data for Time Travel operations
How is unstructured data retrieved from data storage?
SQL functions like the GET command can be used to copy the unstructured data to a location on the client.
SQL functions can be used to create different types of URLs pointing to the unstructured data. These URLs can be used to download the data to a client.
SQL functions can be used to retrieve the data from the query results cache. When the query results are output to a client, the unstructured data will be output to the client as files.
SQL functions can call on different web extensions designed to display different types of files as a web page. The web extensions will allow the files to be downloaded to the client.
Unstructured data stored in Snowflake can be retrieved by using SQL functions to generate URLs that point to the data. These URLs can then be used to download the data directly to a client
What is the minimum Snowflake Edition that supports secure storage of Protected Health Information (PHI) data?
Standard Edition
Enterprise Edition
Business Critical Edition
Virtual Private Snowflake Edition
The minimum Snowflake Edition that supports secure storage of Protected Health Information (PHI) data is the Business Critical Edition. This edition offers enhanced security features necessary for compliance with regulations such as HIPAA and HITRUST CSF4.
Which function unloads data from a relational table to JSON?
TO_OBJECT
TO_JSON
TO_VARIANT
OBJECT CONSTRUCT
The TO_JSON function is used to convert a VARIANT value into a string containing the JSON representation of the value. This function is suitable for unloading data from a relational table to JSON format. References: [COF-C02] SnowPro Core Certification Exam Study Guide
Which Snowflake object does not consume any storage costs?
Secure view
Materialized view
Temporary table
Transient table
Temporary tables do not consume any storage costs in Snowflake because they only exist for the duration of the session that created them and are automatically dropped when the session ends, thus incurring no long-term storage charges4.

Which statistics can be used to identify queries that have inefficient pruning? (Select TWO).
Bytes scanned
Bytes written to result
Partitions scanned
Partitions total
Percentage scanned from cache
The statistics that can be used to identify queries with inefficient pruning are ‘Partitions scanned’ and ‘Partitions total’. These statistics indicate how much of the data was actually needed and scanned versus the total available, which can highlight inefficiencies in data pruning34.
How can performance be optimized for a query that returns a small amount of data from a very large base table?
Use clustering keys
Create materialized views
Use the search optimization service
Use the query acceleration service
The search optimization service in Snowflake is designed to improve the performance of selective point lookup queries on large tables, which is ideal for scenarios where a query returns a small amount of data from a very large base table1.

Which command is used to unload data from a Snowflake database table into one or more files in a Snowflake stage?
CREATE STAGE
COPY INTO
