Discuss Snowflake ARA-R01 Exam Topic 4 Question 48

Which query will identify the specific days and virtual warehouses that would benefit from a multi-cluster warehouse to improve the performance of a particular workload?

AOption A

BOption B

COption C

DOption D

Suggested Answer: B

The correct answer is option B. This query is designed to assess the need for a multi-cluster warehouse by examining the queuing time (AVG_QUEUED_LOAD) on different days and virtual warehouses. When the AVG_QUEUED_LOAD is greater than zero, it suggests that queries are waiting for resources, which can be an indicator that performance might be improved by using a multi-cluster warehouse to handle the workload more efficiently. By grouping by date and warehouse name and filtering on the sum of the average queued load being greater than zero, the query identifies specific days and warehouses where the workload exceeded the available compute resources. This information is valuable when considering scaling out warehouses to multi-cluster configurations for improved performance.

I remember practicing a question that asked about optimizing warehouse performance, and I think it had to do with analyzing specific days. Maybe option C?

Blossom 4 months ago

I feel like option B might be the right choice since it seems to focus on performance metrics, but I'm not entirely sure.

I think we discussed something similar in class about identifying workloads for multi-cluster warehouses, but I can't remember the exact query structure.
