Scenario: A DBA needs to design a clustering strategy for a new DB2 database. What factors should they consider when selecting a clustering key?

Data distribution, uniqueness, and access pattern
Query optimization techniques and indexing algorithms
Server hardware specifications and operating system
Table size, number of columns, and indexing strategy

When selecting a clustering key, a DBA should consider factors such as the distribution of data values, the uniqueness of the key, and the access patterns of the queries. A clustering key should ideally distribute data evenly across the table to prevent hot spots, ensure uniqueness to avoid duplicates, and align with common query patterns to optimize query performance.
