How would you handle a practical scenario involving Partitioning in SQL Server?

For a practical scenario involving Partitioning, I would first clarify the business goal, scale, constraints, and the failure or quality attribute being tested. Partitioning divides large tables or indexes into manageable segments based on a partitioning key. The scenario centers on for a multi-year event table, explain when date-based partitioning helps and how you would verify that queries actually benefit from partition elimination. I would then compare the main alternatives and tradeoffs, identify likely failure modes, and explain how I would validate the solution through testing, observability, security controls, and recovery or rollback planning.
