Detailed Answer
Answer (D) is correct.
Compatibility tests restrict access to the computer system by determining
whether access by a given user (or device) is compatible with the nature
of the attempted use. A series of passwords or identification numbers
may be required to gain access to the system, to examine data files, and
to perform processing using particular programs. Thus, a clerk might be
authorized only to read the data in a given file while using a specified
terminal, but his or her superior might be able to update the file.
Compatibility tests require online storage of authorization tables or
matrices that specify the access permitted to specified codes and devices.
The number of authorized inquiries per user is not included in such a
table.
