intermediate

What is a best practice when using Search Optimization Service?

Enable it only on tables where search queries are frequent and performance matters, to balance cost and benefit.

What does Search Optimization Service primarily improve in Snowflake?

A Speed of search queries on large tables

B Data loading speed

C User authentication

D Backup and recovery

Search Optimization Service is designed to speed up search queries by creating indexes.

How do you activate Search Optimization Service on a table?

A ALTER TABLE &lt;table&gt; SET AUTO_CLUSTERING = TRUE;

B ALTER TABLE &lt;table&gt; SET SEARCH_OPTIMIZATION = TRUE;

C ENABLE SEARCH ON &lt;table&gt;

D CREATE INDEX ON &lt;table&gt;

The correct command to enable Search Optimization Service is ALTER TABLE with SET SEARCH_OPTIMIZATION = TRUE.

Which type of data benefits most from Search Optimization Service?

A Temporary tables

B Small lookup tables

C Tables with only numeric data
