Snowflake Exam DEA-C01 Topic 1 Question 21 Discussion

Actual exam question for Snowflake's DEA-C01 exam
Question #: 21
Topic #: 1
[All DEA-C01 Questions]

A company is building a dashboard for thousands of Analysts. The dashboard presents the results of a few summary queries on tables that are regularly updated. The query conditions vary by tope according to what data each Analyst needs Responsiveness of the dashboard queries is a top priority, and the data cache should be preserved.

How should the Data Engineer configure the compute resources to support this dashboard?

Show Suggested Answer Hide Answer
Suggested Answer: B

This option is the best way to configure the compute resources to support this dashboard. By assigning all queries to a multi-cluster virtual warehouse set to maximized mode, the Data Engineer can ensure that there is enough compute capacity to handle thousands of concurrent queries from different analysts. A multi-cluster virtual warehouse can scale up or down by adding or removing clusters based on the load. A maximized scaling policy ensures that there is always at least one cluster running and that new clusters are added as soon as possible when needed. By monitoring the utilization and performance of the virtual warehouse, the Data Engineer can determine the smallest suitable number of clusters that can meet the responsiveness requirement and minimize costs.

That's true, but what if some warehouses are underutilized? Monitoring could be a hassle.

That could work, but we need to monitor query runtimes to resize if needed.

We could also create a size XL virtual warehouse to support all dashboard queries.

I'm not sure if that would be efficient. Maybe we should monitor utilization first.

What about creating a virtual warehouse for every 250 Analysts?

That sounds like a good idea. We can let the system start and stop clusters based on demand.

I think we should assign queries to a multi-cluster virtual warehouse with economy auto-scaling.
