Snowflake SnowPro Core Certification Exam Sample Questions (Q78-Q83):

NEW QUESTION # 78
Which Snowflake feature or tool helps troubleshoot issues in SQL query expressions that commonly cause performance bottlenecks?

Answer: B

Explanation:
The Snowflake feature that helps troubleshoot issues in SQL query expressions and commonly identify performance bottlenecks is the Query Profile. The Query Profile provides a detailed breakdown of a query's execution plan, including each operation's time and resources consumed. It visualizes the steps involved in the query execution, highlighting areas that may be causing inefficiencies, such as full table scans, large joins, or operations that could benefit from optimization.
By examining the Query Profile, developers and database administrators can identify and troubleshoot performance issues, optimize query structures, and make informed decisions about potential schema or indexing changes to improve performance.

NEW QUESTION # 79
What Snowflake features allow virtual warehouses to handle high concurrency workloads? (Select TWO)

Answer: C,D

Explanation:
Snowflake's architecture is designed to handle high concurrency workloads through several features, two of which are particularly effective:
B . The use of warehouse auto scaling: This feature allows Snowflake to automatically adjust the compute resources allocated to a virtual warehouse in response to the workload. If there is an increase in concurrent queries, Snowflake can scale up the resources to maintain performance.
D . Use of multi-clustered warehouses: Multi-clustered warehouses enable Snowflake to run multiple clusters of compute resources simultaneously. This allows for the distribution of queries across clusters, thereby reducing the load on any single cluster and improving the system's ability to handle a high number of concurrent queries.
These features ensure that Snowflake can manage varying levels of demand without manual intervention, providing a seamless experience even during peak usage.
