Q191.
What is the purpose of fault tree analysis?

a.

To determine the hazard level of different types of faults

b.

To derive a contradiction by reasoning backwards from an undesirable end situation

c.

To increase confidence in failure-free behavior

d.

To detect faults

Discuss
Answer: (b).To derive a contradiction by reasoning backwards from an undesirable end situation Explanation:Fault tree analysis is a special technique developed to find critical faults. Its purpose is to derive a contradiction by reasoning backwards from a given, undesirable end situation. If a contradiction can be derived, it means that the particular situation can never be reached.
Q192.
What is the purpose of using a test adequacy criterion?

a.

To measure the quality of the test set

b.

To determine when sufficient testing has been done

c.

To guide the test selection process

d.

All of the above

Discuss
Answer: (d).All of the above Explanation:The test adequacy criterion is used as a stopping rule, a measurement, or as a test case generator. It helps in determining when sufficient testing has been done, measures the quality of the test set, and guides the test selection process.
Q193.
What is the function of a test adequacy criterion in the test selection process?

a.

To measure the quality of the test set

b.

To determine when sufficient testing has been done

c.

To generate additional test cases

d.

To track the execution of statements and branches

Discuss
Answer: (c).To generate additional test cases Explanation:In the test selection process, if 100% statement coverage has not been achieved yet, an additional test case is selected that covers one or more statements yet untested. The test adequacy criterion is used in a generative view to select test cases.
Q194.
How does the test adequacy criterion help in determining when sufficient testing has been done?

a.

By tracking the execution of statements and branches

b.

By generating additional test cases

c.

By specifying requirements for testing

d.

By measuring the quality of the test set

Discuss
Answer: (d).By measuring the quality of the test set Explanation:If a test adequacy criterion is used as a stopping rule, it tells us when sufficient testing has been done. If statement coverage is the criterion, we may stop testing if all statements have been executed by the tests done so far. The test adequacy criterion, in this case, is used as a measurement to determine if enough testing has been done.
Q195.
How is the test adequacy criterion linked to test techniques?

a.

The test adequacy criterion is used to track the execution of statements and branches

b.

The test adequacy criterion is independent of the test technique

c.

The test adequacy criterion is used to generate additional test cases

d.

The test adequacy criterion is closely linked to test techniques

Discuss
Answer: (d).The test adequacy criterion is closely linked to test techniques Explanation:The test adequacy criteria are closely linked to test techniques. For example, coverage-based test techniques keep track of which statements, branches, etc. are executed and this helps to determine whether a coverage-based adequacy criterion has been met or not.
Q196.
What is the main goal of testing in a software system?

a.

To discover as many faults as possible

b.

To achieve a high reliability

c.

To find the probability of failure-free behavior

d.

To mimic the daily operation of the software system

Discuss
Answer: (b).To achieve a high reliability Explanation:The main goal of testing in a software system is to achieve a high reliability. If failures are more important than faults, the goal pursued during the test phase may change and random testing can be used to obtain confidence in the daily operation of the software system.
Q197.
What is the Cleanroom development method?

a.

A method where the code is executed by the programmer

b.

A method where the input is generated based on expected operational use of the system

c.

A method where manual techniques such as stepwise abstraction are used

d.

A method where the development of individual components is done by different people

Discuss
Answer: (d).A method where the development of individual components is done by different people Explanation:The Cleanroom development method is a method where the development of individual components is done by programmers who are not allowed to actually execute their code. They must then convince themselves of the correctness of their components using manual techniques such as stepwise abstraction. The components are then integrated and tested by someone else.
Q198.
Can random testing be used to find as many faults as possible?

a.

Yes

b.

No

c.

May be Yes or No

d.

Can't say

Discuss
Answer: (b).No Explanation:Random testing does not work well if the goal is to find as many faults as possible. Different test techniques are used in that case. But, if the goal is to achieve a high reliability, random testing can be used.
Q199.
What is the focus of software reliability?

a.

The discovery of faults

b.

The assessment of failure probability

c.

The use of manual techniques

d.

The execution of a large number of test cases

Discuss
Answer: (b).The assessment of failure probability Explanation:The quantitative assessment of failure probability brings the area of software reliability. The main focus is on the assessment of failure probability rather than the discovery of faults.
Q200.
What was the primary goal of the demonstration model in the early days of computing?

a.

To make sure the software passes all tests from the test set.

b.

To make sure the software solves the problem.

c.

To convince others that the software does not contain errors.

d.

To obtain a carefully chosen test set.

Discuss
Answer: (b).To make sure the software solves the problem. Explanation:The primary goal of the demonstration model was to make sure that the program runs and solves the problem.
