Answer to Question 1

4
Rationale: RAID technology uses two or more hard drives that are interconnected to duplicate data. Magnetic tapes, optical media, and portable hard drives do not automatically store duplicate copies of data.

Answer to Question 2

4
Rationale: E-learning works well for corporate training because it allows users to skip material that they already know. It is considered to be efficient for corporate purposes. A chat room would be too limiting for training purposes.
