- A.
  
  $6,800; $44,000; $46,000
- B.
  
  $7,000; $7,500; $52,000
- C.
  
  $46,001; $57,000; $81,000
- D.
  
  $36,000; $46,000; $78,000
Correct Answer
D. $36,000; $46,000; $78,000

Explanation
The four equivalence classes would be:

$1 to $6,000
$6,001 to $34,000
$34,001 to $80,000
$80,001 +

Clearly, the values in option D all fall into the third equivalence class.

Which of the following statements about reviews is true?
- A.
  
  Reviews cannot be performed on user requirements specifications.
- B.
  
  Reviews are the least effective way of testing code.
- C.
  
  Reviews are unlikely to find faults in test plans.
- D.
  
  Reviews should be performed on specifications, code, and test plans.
Correct Answer
D. Reviews should be performed on specifications, code, and test plans.

Explanation
The first three answers are wrong because reviews definitely can be performed on documents including user requirements specifications and test plans, and code reviews can be an effective way of testing code.

3.

A failure is:
- A.
  
  Found in the software and is the result of an error.
- B.
  
  A departure from specified behaviour.
- C.
  
  An incorrect step, process or data definition in a computer program.
- D.
  
  A human action that produces an incorrect result.
Correct Answer
B. A departure from specified behaviour.

Explanation
We need to be careful to distinguish the terms error (or mistake) from defect (or bug or fault) from failure. An error can cause a defect which may result in a failure. Answers A & C are defects, and answer D is an error.

Static analysis is best described as:
- A.
  
  The analysis of batch programs.
- B.
  
  The reviewing of test plans.
- C.
  
  The analysis of program code.
- D.
  
  The use of black box testing.
Correct Answer
C. The analysis of program code.

Explanation
Static analysis is the analysis of software artifacts, for example, requirements or code. Note that black box testing is testing without reference to the internal structure of the component or system, whereas in static analysis we might actually look through the code (or use a tool to do this).

Enough testing has been performed when:
- A.
  
  Time runs out.
- B.
  
  The required level of confidence has been achieved.
- C.
  
  No more faults are found.
- D.
  
  The users won't find any serious faults.
Correct Answer
B. The required level of confidence has been achieved.

Explanation
Even though in real life we often end up stopping when time runs out, we should continue until the required level of confidence has been achieved.

What is the main difference between a walkthrough and an inspection?
- A.
  
  An inspection is led by the author, whereas a walkthrough is led by a trained moderator.
- B.
  
  An inspection has a trained leader, whereas a walkthrough has no leader.
- C.
  
  Authors are not present during inspections, whereas they are present during walkthroughs.
- D.
  
  A walkthrough is led by the author, whereas an inspection is led by a trained moderator.
Correct Answer
D. A walkthrough is led by the author, whereas an inspection is led by a trained moderator.

Explanation
A walkthrough is a step-by-step presentation by the author to gain information and to establish common understanding; it is led by the author. An inspection is a peer review led by a moderator.
