Correct Answer: D Because the database consumes 5TB only the advanced editions do not have resource limitations. An enterprise edition is needed for Analytics and BLU.

The good answer is "D. DB2 Advanced Enterprise Server Edition". DB2 Express-C is died in the version 11.1. DB2 Workgroup Server Edition is an appropriated edition of DB2 for a smal business. DB2 Enterprise Server Edition is most appropriate for medium-to-large enterprise-wide solutions with hundreds of users but is not most appropriated to run long, complex queries that select a subset of columns perform grouping and aggregation. Indeed, Advanced Workgroup Server Edition, Advanced Enterprise Server Edition and DIrect Advanced Edition are the only editions which offer "DB2 - Blu - table organized by column" feature to accelerate long, complex queries that select a subset of columns and often perform grouping and aggregation.
