    2. BCREATE TABLE employee (empid INT, resume XML(2000))
    3. CCREATE TABLE employee (empid INT, resume CLOB AS XML)
    4. DCREATE TABLE employee (empid INT, resume CLOB USING XML)
13. 13Which DB2 product provides a complete data warehousing solution that contains components that facilitate data warehouse construction and administration?

    1. ADB2 pureScale Feature
    2. BDB2 Workload Manger
    3. CIBM InfoSphere Warehouse
    4. DDatabase Partitioning Feature
14. 14Which statement about IBM Data Studio is NOT true?

    1. AThe IBM Data Studio administration client can be installed on servers running Red Hat Linux, SUSE Linux, Windows, and AIX.
    2. BThe IBM Data Studio replaces the DB2 Control Center as the standard GUI interface for DB2 database administration and application development.
    3. CThe IBM Data Studio is an Eclipse-based, integrated development environment (IDE) that can be used to perform instance and database administration.
    4. DThe IBM Data Studio allows users to connect to a DB2 database using a wizard; however, users are rewpuir4ed to provide login credentials before a connection will be established.
15. 15Which statement about inline large objects (LOBs) is NOT true?

    1. AWhen a table contains columns with inline LOBs, fewer rows can fit on a page.
    2. BInline LOBs are created by appending the INLINE LENGTH clause to a LOB column's definition.
    3. CBecause DML operations against inline LOBs are never logged, their use can reduce logging overhead.
    4. DInline LOBs improve query performance by storing LOB data in the same data pages as the rest of a table's rows, rather that in a separate LOB storage object.
