A Snowflake Administrator is investigating why a query is not re-using the persisted result cache. The Administrator found the two relevant queries from the SNOWFLAKE. ACCOUNT_USAGE. QUERY_HISTORY view: Why is the second query re-scanning micro-partitions instead of using the first query's persisted result cache?
A Snowflake account is configured with SCIM provisioning for user accounts and has bi-directional synchronization for user identities. An Administrator with access to SECURITYADMIN uses the Snowflake UI to create a user by issuing the following commands: use role USERADMIN; create or replace role DEVELOPER_ROLE; create user PTORRES PASSWORD = 'hello world!' MUST_CHANGE_PASSWORD = FALSE default_role = DEVELOPER_ROLE; The new user named PTORRES successfully logs in, but sees a default role of PUBLIC in the web UI. When attempted, the following command fails: use DEVELOPER_ROLE; Why does this command fail?
If the query matches the definition, will Snowflake always dynamically rewrite the query to use a materialized view?
A Snowflake Administrator created a role ROLE_MANAGED_ACCESS and a schema SCHEMA_MANAGED_ACCESS as follows: USE ROLE SECURITYADMIN; CREATE ROLE ROLE_MANAGED_ACCESS; GRANT ROLE ROLE_MANAGED_ACCESS TO ROLE SYSADMIN; GRANT USAGE ON WAREHOUSE COMPUTE_WH TO ROLE ROLE_MANAGED_ACCESS; GRANT ALL privileges ON DATABASE WORK TO ROLE ROLE_MANAGED_ACCESS; USE ROLE ROLE_MANAGED_ACCESS; CREATE SCHEMA SCHEMA_MANAGED_ACCESS WITH MANAGED ACCESS; USE ROLE SECURITYADMIN; GRANT SELECT, INSERT ON FUTURE TABLES IN SCHEMA SCHEMA MANAGED ACCESS to ROLE_MANAGED_ACCESS; The Administrator now wants to disable the managed access on the schema. How can this be accomplished?

A Snowflake Administrator needs to set up Time Travel for a presentation area that includes facts and dimensions tables, and receives a lot of meaningless and erroneous loT data. Time Travel is being used as a component of the company's data quality process in which the ingestion pipeline should revert to a known quality data state if any anomalies are detected in the latest load. Data from the past 30 days may have to be retrieved because of latencies in the data acquisition process. According to best practices, how should these requirements be met? (Select TWO).

When creating a row access policy, which code snippet below will provide privileges to the role ALL_ACCESS_ROLE to see all rows regardless of region, while the other roles can only see rows for their own regions?

A.
create or replace row access policy region policy as (region_value varchar) returns boolean -> 'ALL ACCESS_ROLE' = current_role () and exists ( select 1 from entitlement_table where role = current_role () and region = region_value )
Answers

Answers
B.
create or replace row access policy region policy as (region_value varchar) returns boolean -> exists ( select 1 from entitlement_table where role = current_role () and region = region_value )
C.
create or replace row access policy region policy as (region_value varchar) returns boolean -> 'ALL_ACCESS_ROLE' = current_role () or exists ( select 1 from entitlement_table where role = current_role () and region = region_value )
Answers
C.
create or replace row access policy region policy as (region_value varchar) returns boolean -> 'ALL_ACCESS_ROLE' = current_role () or exists ( select 1 from entitlement_table where role = current_role () and region = region_value )
D.
create or replace row access policy region policy as (region_value varchar) returns boolean -> 'ALL ACCESS ROLE' = current_role () )
Answers
D.
create or replace row access policy region policy as (region_value varchar) returns boolean -> 'ALL ACCESS ROLE' = current_role () )
Suggested answer: C

Explanation:

This code snippet will create a row access policy that returns true if the current role is ALL_ACCESS_ROLE or if the current role matches the region value in the entitlement_table. This means that the ALL_ACCESS_ROLE can see all rows regardless of region, while the other roles can only see rows for their own regions. According to theSnowflake documentation, the CURRENT_ROLE context function returns the name of the current role for the session. The EXISTS function returns true if the subquery returns any rows. The OR operator returns true if either operand is true. Therefore, this code snippet satisfies the requirements of the question.
