NEW QUESTION # 221
How does Snowflake recommend defining a clustering key on a high-cardinality column that includes a 15 digit ID numbered column. ID_NUMBER?
Answer: B
Explanation:
* Clustering keys improve query performance by organizing data to optimize retrieval for frequently queried columns.
* For high-cardinality columns like a 15-digit ID, Snowflake recommends bucketing or truncating the column values to reduce cardinality.
* The function TRUNC(ID_NUMBER, -6) truncates the ID number by dropping the last 6 digits, reducing the number of unique values while maintaining relevance for clustering.
Key Steps:
* Use TRUNC to reduce high-cardinality column values for efficient clustering.
* Monitor clustering key performance via clustering depth metrics.

How can a Snowflake user access a JSON object, given the following table? (Select TWO).
Answer: B,E
Explanation:
To access a JSON object in Snowflake, dot notation is used where the path to the object is specified after the column name containing the JSON data.

NEW QUESTION # 223
What does Snowflake attempt to do if any of the compute resources for a virtual warehouse fail to provision during start-up?
Answer: C
Explanation:
If any compute resources for a virtual warehouse fail to provision during startup, Snowflake will attempt to restart those failed resources. The system is designed to automatically handle transient issues that might occur during the provisioning of compute resources. By restarting the failed resources, Snowflake aims to ensure that the virtual warehouse has the necessary compute capacity to handle the user's workloads without manual intervention.

NEW QUESTION # 224
Who can create network policies within Snowflake? (Select TWO).
Answer: C,E
Explanation:
In Snowflake, network policies define the allowed IP address ranges from which users can connect to Snowflake, enhancing security by restricting access based on network location. The creation and management of network policies require sufficient privileges. Specifically, a user with theSECURITYADMINrole or any role with higher privileges, such asACCOUNTADMIN, can create network policies. Additionally, a custom role can be granted theCREATE NETWORK POLICYprivilege, enabling users assigned to that role to also create network policies. This approach allows for flexible and secure management of network access to Snowflake.
