   A company enables Search Optimization on a large `customers` table that is frequently updated. They notice an increase in storage costs and want to understand why. What is the most likely reason for the cost increase?

   • ASearch Optimization requires additional compute credits for every query run.
   • BSearch Optimization creates and maintains a separate search access path that consumes additional storage.
   • CSearch Optimization automatically reclusters the table, increasing storage overhead.
   • DSearch Optimization forces a full table scan on every query, increasing compute costs.

   A data engineer has set a clustering key on a large `orders` table. After a bulk load of new data, they notice that the clustering depth has increased. What is the expected behavior of automatic clustering in this situation?

   • AAutomatic clustering will stop because the table is too large.
   • BAutomatic clustering will gradually recluster the table as background services run, eventually reducing clustering depth.
   • CAutomatic clustering will immediately recluster the entire table in the background.
   • DAutomatic clustering will not run until the table is manually reclustered.

   What is the primary purpose of defining clustering keys on a large Snowflake table?

   • ATo automatically compress the table to reduce storage costs
   • BTo improve query performance by physically co-locating rows with similar key values in the same micro-partitions
   • CTo enforce uniqueness constraints on the table's columns
   • DTo speed up data loading by parallelizing inserts

   What is a recommended practice for maintaining a clustered table in Snowflake?

   • AMonitor clustering depth and let automatic clustering handle maintenance
   • BAvoid DML operations on clustered tables to prevent degradation
   • CManually recluster after every insert
   • DRecreate the table periodically to reset clustering

   When would a user choose to manually recluster a table instead of relying on automatic clustering?

   • AWhen the table has no clustering key defined
   • BWhen the table is read-only and never modified
   • CWhen immediate performance improvement is needed and automatic clustering has not yet run
   • DWhen the table is small and rarely updated
