NEW QUESTION # 380
What is the consequence of disabling auto-suspend for a Snowflake virtual warehouse?
- A. Increased credit consumption
- B. Reduced storage costs
- C. Improved query performance
- D. Enhanced data security
Answer: A
Explanation:
* Disabling auto-suspend prevents a virtual warehouse from automatically shutting down during periods of inactivity, leading to increased credit consumption because the warehouse continues consuming resources even when idle.
* This can significantly raise costs, especially for underutilized warehouses.

NEW QUESTION # 384
Which Snowflake layer is associated with virtual warehouses?
- A. Database storage
- B. Cloud services
- C. Query processing
- D. Elastic memory
Answer: C
Explanation:
The layer of Snowflake's architecture associated with virtual warehouses is the Query Processing layer.
Virtual warehouses in Snowflake are dedicated compute clusters that execute SQL queries against the stored data. This layer is responsible for the entire query execution process, including parsing, optimization, and the actual computation. It operates independently of the storage layer, enabling Snowflake to scale compute and storage resources separately for efficiency and cost-effectiveness.

* Snowflake Documentation: Snowflake Architecture
NEW QUESTION # 385
How many credits does a size 3X-Large virtual warehouse consume if it runs continuously for 2 hours?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: D
Explanation:
In Snowflake, the consumption of credits by a virtual warehouse is determined by its size and the duration for which it runs. A size 3X-Large virtual warehouse consumes 128 credits if it runs continuously for 2 hours.
This consumption rate is based on the principle that larger warehouses, capable of providing greater computational resources and throughput, consume more credits per hour of operation. The specific rate of consumption is defined by Snowflake's pricing model and the scale of the virtual warehouse.References:Snowflake Pricing Documentation
NEW QUESTION # 386

What is a limitation of a Materialized View?
- A. A Materialized View can only reference up to two tables
- B. A Materialized View cannot support any aggregate functions
- C. A Materialized View cannot be joined with other tables
- D. A Materialized View cannot be defined with a JOIN
Answer: D
Explanation:
Materialized Views in Snowflake are designed to store the result of a query and can be refreshed to maintain up-to-date data. However, they have certain limitations, one of which is that they cannot be defined using a JOIN clause. This means that a Materialized View can only be created based on a single source table and cannot combine data from multiple tables using JOIN operations.
