Which of the following statements about conventional tablespaces (non-locally managed tablespaces) are true? Each correct answer represents a part of the solution. Choose two

Answer: A,C

Explanation: Answer options A and C are correct. In case of conventional tablespaces (the approach of Oracle7i and below), Oracle uses data dictionary tables to manage storage space. When a new extent is allocated to a segment under a conventional tablespace , its allocation is reflected by updating the corresponding segment header and the associated data dictionary tables. B and D are incorrect. In case of a locally managed tablespace , Oracle uses a bitmap for managing the storage space.
