QUESTION: 38

The following is returned from SYSTEM$CLUSTERING_INFORMATION() for a table named ORDERS with a DATE column named O_ORDERDATE:

What does the total_constant_partition_count value indicate about this table?

The table is clustered very well on O_ORDERDATE, as there are 493 micro-partitions that could not be significantly improved by re-clustering.
The table is not clustered well on O_ORDERDATE, as there are 493 micro-partitions where the range of values in that column overlap with every other micro-partition in the table.
The data in O_ORDERDATE does not change very often, as there are 493 micro-partitions containing rows where that column has not been modified since the row was created.
The data in O_ORDERDATE has a very low cardinality, as there are 493 micro-partitions where there is only a single distinct value in that column for all rows in the micro-partition.

QUESTION: 39

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 topic 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?

Assign queries to a multi-cluster virtual warehouse with economy auto-scaling. Allow the system to automatically start and stop clusters according to demand.
Assign all queries to a multi-cluster virtual warehouse set to maximized mode. Monitor to determine the smallest suitable number of clusters.
Create a virtual warehouse for every 250 Analysts. Monitor to determine how many of these virtual warehouses are being utilized at capacity.
Create a size XL virtual warehouse to support all the dashboard queries. Monitor query runtimes to determine whether the virtual warehouse should be resized.
