Student answers will vary. Example answers are: Disaster might be the most difficult because it is unexpected, broad-based, and frequently life threatening. In addition, the company cannot know if the disaster plan will work until a disaster occurs, and then it's too late to make corrections. Security might be the most difficult because it is an ongoing problem, new viruses are devised constantly, and hackers get smarter every day. Furthermore, damage done by a trusted employee from inside cannot be obviated by system security measures. Human error might be most difficult because it isn't caught until too late, and the consequences may be disastrous. Also, administrative error can occur at any level and through any operation or procedure in the company.

Ans. to #5

While choosing primary keys for a data model, database developers use autonumbering to assign primary keys. In this method, the DBMS assigns incremental numbers to records as they are created. This approach ensures that each record has a unique primary key and that no one accidentally gives the same ID number to two different people. Also, because the autonumber has no other meaning, there would be no reason to ever change it.

Ans. to #6

FALSE

Ans. to #7
