Question 1
What can you achieve by implementing reverse key index?
- Reverse the bytes of each column indexed including the row ID
- Store a bitmap for each key value instead of a list of row IDs in the leaf node
- Prevent contention on the highest leaf block when using sequences to generate keys
- Remove repeated key values from the index to fit more index entries in a given amount of disk space
Correct answer: C
Question 2

- One audit record is created for the whole session if user SCOTT successfully drops one or more tables in his session
- One audit record is created for every session of any other user in which a table owned by SCOTT is dropped successfully
- One audit record is created for every successful DROP TABLE command executed by any user to drop tables owned by SCOTT
