NEW QUESTION # 570
What factors impact storage costs in Snowflake? (Select TWO).
Answer: A,D
Explanation:
The factors that impact storage costs in Snowflake include the account type (Capacity or On Demand) and the cloud region used by the account. These factors determine the rate at which storage is billed, with different regions potentially having different rates3.
NEW QUESTION # 571
Which Snowflake data type is used to store JSON key value pairs?
Answer: A
Explanation:
The VARIANT data type in Snowflake is used to store JSON key-value pairs along with other semi-structured data formats like AVRO, BSON, and XML. The VARIANT data type allows for flexible and dynamic data structures within a single column, accommodating complex and nested data. This data type is crucial for handling semi-structured data in Snowflake, enabling users to perform SQL operations on JSON objects and arrays directly.

Snowflake Documentation: Semi-structured Data Types
NEW QUESTION # 572
What is the MAXIMUM number of clusters that can be provisioned with a multi-cluster virtual warehouse?
Answer: B
Explanation:
In Snowflake, the maximum number of clusters that can be provisioned within a multi-cluster virtual warehouse is 10. This allows for significant scalability and performance management by enabling Snowflake to handle varying levels of query load by adjusting the number of active clusters within the warehouse.
References: Snowflake documentation on virtual warehouses, particularly the scalability options available in multi-cluster configurations.
NEW QUESTION # 573
For which use case will transient tables be most cost-effective?
Answer: B
Explanation:
The correct answer is A. The table data does not require Fail-safe .
Transient tables are designed for data that does not need the same level of data recovery protection as permanent tables. Unlike permanent tables, transient tables do not have a Fail-safe period.
Why A is correct:
Fail-safe storage can add cost because Snowflake retains historical data for recovery by Snowflake support after the Time Travel retention period ends. Since transient tables do not have Fail-safe, they can reduce storage costs for data that does not require this additional protection.
Common use cases include:
Temporary ETL data
Staging data
Intermediate transformation data
Reproducible data
Non-critical working data
Why the other options are incorrect:
B). Long-term critical storage is usually better suited for permanent tables because they support Fail-safe.
C). Frequent access and modification alone does not make a transient table the best cost choice. The key factor is whether Fail-safe is needed.
D). Sharing data with external accounts is not the primary cost-effective use case for transient tables.
Official Snowflake documentation reference:
Snowflake documentation explains that transient tables persist until explicitly dropped, support Time Travel with limited retention, and do not have a Fail-safe period.
Reference: Snowflake Documentation - Transient tables; Snowflake Documentation - Understanding and viewing Fail-safe; SnowPro Core Study Guide - Snowflake Architecture.
NEW QUESTION # 574
By default, which role can create resource monitors?
Answer: D
Explanation:
The role that can by default create resource monitors in Snowflake is theACCOUNTADMINrole. Resource monitors are a crucial feature in Snowflake that allows administrators to track and control the consumption of compute resources, ensuring that usage stays within specified limits. The creation and management of resource monitors involve defining thresholds for credits usage, setting up notifications, and specifying actions to be taken when certain thresholds are exceeded.
Given the significant impact that resource monitors can have on the operational aspects and billing of a Snowflake account, the capability to create and manage them is restricted to theACCOUNTADMINrole. This role has the broadest set of privileges in Snowflake, including the ability to manage all aspects of the account, such as users, roles, warehouses, databases, and resource monitors, among others.
