* In a multi-cluster virtual warehouse, Snowflake allows you to scale-out by adding more clusters to handle concurrent queries.
* Increasing the MAX_CLUSTER_COUNT ensures more clusters are dynamically provisioned during high-concurrency periods, reducing queuing.
Why Other Options Are Incorrect:
* A. Increase warehouse size: Increases compute power for individual queries but does not address concurrency issues.
* B. Use economy scaling policy: Economy scaling is unrelated to reducing query queuing.
* D. Convert to Snowpark-optimized warehouse: Snowpark warehouses are designed for ML and Python-based workloads, not for query concurrency.

For loading data into Snowflake via Snowpipe, the recommended compressed file size is between 100-250 MB. This size range is optimal for balancing the performance of parallel processing and minimizing the overhead associated with handling many small files2.

OPERATE. In Snowflake, to pause or resume a pipe, the OPERATE privilege is required on the pipe object.
The OPERATE privilege allows users to perform operational tasks on specific objects such as pipes, tasks, and streams. Specifically, for a pipe, the OPERATE privilege enables the user to execute the ALTER PIPE
... SET PIPE_EXECUTION_PAUSED=TRUE or ALTER PIPE ... SET
PIPE_EXECUTION_PAUSED=FALSE commands, which are used to pause or resume the pipe, respectively.
Here's a step-by-step explanation and reference:
* Understanding Pipe Operations: Pipes in Snowflake are used for continuous data loading from staging areas into Snowflake tables. Managing pipes involves operations such as creating, monitoring, pausing, and resuming.
* Privileges for Pipe Operations: The OPERATE privilege is essential for pausing and resuming pipes.
This privilege is more specific than general object access privileges like SELECT or USAGE and is tailored for operational control.
* Granting the OPERATE Privilege: To grant the OPERATE privilege on a pipe, an administrator or a user with the necessary grants can execute the SQL command:
GRANT OPERATE ON PIPE <pipe_name> TO ROLE <role_name>;
* Pausing and Resuming Pipes: Once the OPERATE privilege is granted, the user or role can pause the pipe using:
ALTER PIPE <pipe_name> SET PIPE_EXECUTION_PAUSED=TRUE;
To resume the pipe, they use:
ALTER PIPE <pipe_name> SET PIPE_EXECUTION_PAUSED=FALSE;
Reference: For more information on pipe operations and privileges, you can refer to Snowflake's official documentation on pipes and security access control: https://docs.snowflake.com/en/sql-reference/sql/grant- privilege.html and https://docs.snowflake.com/en/user-guide/data-pipelines-intro.html#managing-pipes

To temporarily bypass a network policy by configuring the user object property MINS_TO_BYPASS_NETWORK_POLICY, the USERADMIN role should be used. This role has the necessary privileges to modify user properties, including setting a temporary bypass for network policies, which can be crucial for enabling access under specific circumstances without permanently altering the network security configuration.

In Snowflake, each size increase in virtual warehouses doubles the number of servers. Therefore, if a size Small virtual warehouse is made up of two servers, a Large warehouse, which is two sizes larger, would be made up of eight servers (2 servers for Small, 4 for Medium, and 8 for Large)2.
Size specifies the amount of compute resources available per cluster in a warehouse. Snowflake supports the following warehouse sizes:
