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?
What are characteristics of data replication in Snowflake? (Select THREE).
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).

Answers
D.
To keep the query result cache warm for good performance on repeated queries
Suggested answer: C

Explanation:

According to the Snowflake documentation1, the AUTO_SUSPEND property specifies the number of seconds of inactivity after which a warehouse is automatically suspended. If the property is set to 0 or NULL, the warehouse never suspends automatically. For a warehouse that supports several dashboards, issuing various queries on the same database, setting AUTO_SUSPEND to 0 or NULL can help to keep the data cache warm, which means that the data used by the queries is already loaded into the warehouse memory and does not need to be fetched from the storage layer. This can improve the performance of similar queries that access the same data. Option A is incorrect because setting AUTO_SUSPEND to 0 or NULL does not save costs on warehouse shutdowns and startups, but rather increases the costs by keeping the warehouse running continuously. Option B is incorrect because setting AUTO_SUSPEND to 0 or NULL does not run the warehouse as little as possible, but rather runs the warehouse as much as possible. Option D is incorrect because setting AUTO_SUSPEND to 0 or NULL does not affect the query result cache, which is a separate cache that stores the results of previous queries for a period of time. The query result cache is not dependent on the warehouse state, but on the query criteria2.
