Which of the following statements describe features of Snowflake data caching? (Choose two.)

When the data cache is full, the least-recently used data will be cleared to make room.

The RESULT_SCAN table function can access and filter the contents of the query result cache.

When a virtual warehouse is suspended, the data cache is saved on the remote storage layer.

When the data cache is full, the least-recently used data will be cleared to make room.

A user can only access their own queries from the query result cache.

A user must set USE_METADATA_CACHE to TRUE to use the metadata cache in queries.

The RESULT_SCAN table function can access and filter the contents of the query result cache.

A table needs to be loaded. The input data is in JSON format and is a concatenation of multiple JSON documents. The file size is 3 GB. A warehouse size small is being used. The following COPY INTO command was executed:COPY INTO SAMPLE FROM @~/SAMPLE.JSON (TYPE=JSON)The load failed with this error:Max LOB size (16777216) exceeded, actual size of parsed column is 17894470.How can this issue be resolved?

Split the file into multiple files in the recommended size range (100 MB - 250 MB).

Compress the file and load the compressed file.

Split the file into multiple files in the recommended size range (100 MB - 250 MB).

Set STRIP_OUTER_ARRAY=TRUE in the COPY INTO command.

Which of the following describes a Snowflake stored procedure?

They can be created to run with a caller's rights or an owner's rights.

They can be created as secure and hide the underlying metadata from the user.

They can be created to run with a caller's rights or an owner's rights.

How are serverless features billed?

Per minute multiplied by an automatic sizing for the job, with a minimum of one minute

Per second multiplied by an automatic sizing for the job

Per minute multiplied by an automatic sizing for the job, with a minimum of one minute

Per second multiplied by the size, as determined by the SERVERLESS_FEATURES_SIZE account parameter

Serverless features are not billed, unless the total cost for the month exceeds 10% of the warehouse credits, on the account

Which SQL commands, when committed, will consume a stream and advance the stream offset? (Choose two.)

INSERT INTO TABLE SELECT FROM STREAM

ALTER TABLE AS SELECT FROM STREAM

Which methods can be used to delete staged files from a Snowflake stage? (Choose two.)

Specify the PURGE copy option in the COPY INTO <table> command.

Use the REMOVE command after the load completes.

Use the DROP <file> command after the load completes.

Specify the TEMPORARY option when creating the file format.

Specify the PURGE copy option in the COPY INTO <table> command.

Use the REMOVE command after the load completes.

Use the DELETE LOAD HISTORY command after the load completes.

What is an advantage of using an explain plan instead of the query profiler to evaluate the performance of a query?

An explain plan can be used to conduct performance analysis without executing a query.

The explain plan output is available graphically.

An explain plan can be used to conduct performance analysis without executing a query.

An explain plan will handle queries with temporary tables and the query profiler will not.

An explain plan's output will display automatic data skew optimization information.

Why does Snowflake recommend file sizes of 100-250 MB compressed when loading data?

Allows optimization of parallel operations

Optimizes the virtual warehouse size and multi-cluster setting to economy mode

Allows a user to import the files in a sequential order

Increases the latency staging and accuracy when loading the data

Allows optimization of parallel operations

Which of the following features are available with the Snowflake Enterprise edition? (Choose two.)

Database replication and failover

A Snowflake Administrator needs to ensure that sensitive corporate data in Snowflake tables is not visible to end users, but is partially visible to functional managers.How can this requirement be met?

Revoke all roles for functional managers and end users.

What affects whether the query results cache can be used?

If the referenced data in the table has changed

If the query contains a deterministic function

If the virtual warehouse has been suspended

If the referenced data in the table has changed

If multiple users are using the same virtual warehouse

Which of the following is an example of an operation that can be completed without requiring compute, assuming no queries have been executed previously?

Using the command ALTER <object> ADD ROW ACCESS POLICY ;

When should a multi-cluster warehouse be used in auto-scaling mode?

When a large number of concurrent queries are run on the same warehouse

When it is unknown how much compute power is needed

If the select statement contains a large number of temporary tables or Common Table Expressions (CTEs)

If the runtime of the executed query is very slow

When a large number of concurrent queries are run on the same warehouse
