What is the purpose of multi-cluster virtual warehouses?
Options:
A.
To create separate data warehouses to increase query optimization
B.
To allow users the ability to choose the type of compute nodes that make up a virtual warehouse cluster
C.
To eliminate or reduce Queuing of concurrent queries
D.
To allow the warehouse to resize automatically
Answer:
C
Explanation:
Explanation:
Multi-cluster virtual warehouses in Snowflake are designed to manage user and query concurrency needs. They allow for the allocation of additional clusters of compute resources, either statically or dynamically, to handle increased loads and reduce or eliminate the queuing of concurrent queries2.

Question 78
What affects whether the query results cache can be used?
Options:
A.
If the query contains a deterministic function
B.
If the virtual warehouse has been suspended
C.
If the referenced data in the table has changed
D.
If multiple users are using the same virtual warehouse
Answer:
C
Explanation:
Explanation:
The query results cache can be used as long as the data in the table has not changed since the last time the query was run. If the underlying data has changed, Snowflake will not use the cached results and will re-execute the query1.
Question 79
Which of the following accurately describes shares?
Options:
A.
Tables, secure views, and secure UDFs can be shared
B.
Shares can be shared
C.
Data consumers can clone a new table from a share
D.
Access to a share cannot be revoked once granted
Answer:
A
Explanation:
Explanation:
Shares in Snowflake are named objects that encapsulate all the information required to share databases, schemas, tables, secure views, and secure UDFs. These objects can be added to a share by granting privileges on them to the share via a database role
