B. The IMPORT utility can perform lightweight transformations on the data being processed. The INGEST utility cannot transform data.
C. The INGEST is capable of transforming and streaming data from files and pipes at high speeds into DB2 tables. The IMPORT utility cannot transform the data.
D. The IMPORT utility can import data into a database, while the INGEST can only create database objects based on a script file.
How does automatic storage work in DB2?
A. Automatic storage simplifies storage management by allowing you to specify storage paths where the database manager can place table space data.
