A. B. C. D.A.
When verifying the integrity of a relational database management system (RDBMS), an IS auditor should review the following:
A. Cyclic redundancy check value: This is a value calculated by the RDBMS to ensure the data is not corrupted. It's a mathematical algorithm that calculates a fixed-length string of bits based on the data. This value can be used to verify the integrity of the data stored in the database.
B. Secret key algorithm used: This is the algorithm used to encrypt the data in the database. The IS auditor should verify that the algorithm is secure and that the keys used to encrypt and decrypt the data are properly managed.
C. Foreign key attributes: These are attributes that link tables in the database together. The IS auditor should verify that the foreign key attributes are properly defined and that they are not pointing to non-existent data.
D. Database size value: This is the size of the database. While database size is important to monitor, it is not directly related to verifying the integrity of the database.
In conclusion, the correct answer is A. Cyclic redundancy check value.
