QUESTION 1
IS management has decided to rewrite a legacy customer relations system using
fourth-generation languages (4GLs). Which of the following risks is MOST often
associated with system development using 4GLs?
A. Inadequate screen/report design facilities
B. Complex programming language subsets
C. Lack of portability across operating systems
D. Inability to perform data intensive operations
Correct Answer: D
Section: (none)
Explanation
Explanation/Reference:
4GLs are usually not suitable for data intensive operations. Instead, they are
used mainly for graphic user interface (GUI) design or as simple query/report
generators. Screen/report design facilities are one of the main advantages of
4GLs, and 4GLs have simple programming language subsets. Portability is also one
of the main advantages of 4GLs.
QUESTION 2
Which of the following would be the BEST method for ensuring that critical
fields in a master record have been updated properly?
A. Field checks
B. Control totals
C. Reasonableness checks
D. A before-and-after maintenance report
Correct Answer: D
Section: (none)
Explanation
Explanation/Reference:
A before-and-after maintenance report is the best answer because a visual review
would provide the most positive verification that updating was proper.
QUESTION 3
Which of the following is a dynamic analysis tool for the purpose of testing
software modules?
A. Blackbox test
B. Desk checking
C. Structured walk-through
D. Design and code
Correct Answer: A
Section: (none)
Explanation
Explanation/Reference:
A blackbox test is a dynamic analysis tool for testing software modules. During
the testing of software modules a blackbox test works first in a cohesive manner
as one single unit/entity, consisting of numerous modules and second, with the
user data that flows across software modules. In some cases, this even drives the
software behavior. In choices B, C and D, the software (design or code) remains
static and somebody simply closely examines it by applying his/her mind, without
actually activating the software. Hence, these cannot be referred to as dynamic
analysis tools.
