Correct Answer: ACD Section: (none) Explanation Explanation/Reference: Explanation: A: You can create and rebuild indexes online. Therefore, you can update base tables at the same time you are building or rebuilding indexes on that table. You can perform DML operations while the index build is taking place, but DDL operations are not allowed. Parallel execution is not supported when creating or rebuilding an index online. D: Moving (Rebuilding) Index-Organized Tables Because index-organized tables are primarily stored in a B-tree index, you can encounter fragmentation as a consequence of incremental updates. However, you can use the ALTER TABLE...MOVE statement to rebuild the index and reduce this fragmentation. C: If a table can be compressed in the new tablespace, also it can be compressed in the same tablespace. Incorrect: Not B, not E: Local and Global indexes can be automatically rebuild with UPDATE INDEXES when you move the table.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
