Question 36

Which of the following statements best describes how configuration management supports testing?

A. Configuration management helps reduce testing effort by identifying a manageable number of test environment configurations in which to test the software, out of all possible configurations of the environment in which the software will be released
B. Configuration management is an administrative discipline that includes change control, which is the process of controlling the changes to identified items referred to as Configuration Items'
C. Configuration management is an approach to interoperability testing where tests are executed in the cloud, as the cloud can provide cost-effective access to multiple configurations of the test environments
D. Configuration management helps ensure that all relevant project documentation and software items are uniquely identified in all their versions and therefore can be unambiguously referenced in test documentation

Correct Answer:D
This answer is correct because configuration management is a process of establishing and maintaining consistency of a product??s performance, functional, and physical attributes with
its requirements, design, and operational information throughout its life. Configuration management helps ensure that all relevant project documentation and software items are uniquely identified in all their versions and therefore can be unambiguously referenced in test documentation. This supports testing by providing traceability, consistency, and control over the test artifacts and the software under test.

Question 37

Which of the following applications will be the MOST suitable for testing by Use Cases

A. Accuracy and usability of a new Navigation system compared with previous system
B. A billing system used to calculate monthly charge based or large number of subscribers parameters
C. The ability of an Anti virus package to detect and quarantine a new threat
D. Suitability and performance of a Multi media (audio video based) system to a new operating system

Correct Answer:A
A new navigation system compared with a previous system is the most suitable application for testing by use cases, because it involves a high level of interaction between the user and the system, and the expected behavior and outcomes of the system are based on the user??s needs and goals. Use cases can help to specify the functional requirements of the new navigation system, such as the ability to enter a destination, select a route, follow the directions, receive alerts, etc. Use cases can also help to compare the accuracy and usability of the new system with the previous system, by defining the success
and failure scenarios, the preconditions and postconditions, and the alternative flows of each use case. Use cases can also help to design and execute test cases that cover the main and exceptional paths of each use case, and to verify the satisfaction of the user??s expectations.
The other options are not the most suitable applications for testing by use cases, because they do not involve a high level of interaction between the user and the system, or the expected behavior and outcomes of the system are not based on the user??s needs and goals. A billing system used to calculate monthly charge based on a large number of subscriber parameters is more suitable for testing by data-driven testing, which is a technique for testing the functionality and performance of a system or component by using a large set of input and output data. The ability of an antivirus package to detect and quarantine a new threat is more suitable for testing by exploratory testing, which is a technique for testing the functionality and security of a system or component by using an informal and flexible approach, based on the tester??s experience and intuition. The suitability and performance of a multimedia (audio video based) system to a new operating system is more suitable for testing by compatibility testing, which is a technique for testing the functionality and performance of a system or component by using different hardware, software, or network environments.

Question 38

Which sequence of stated in the answer choices is correct in accordance with the following figure depicting the life-cycle of a defect?
CTFL4 dumps exhibit

A. S0->S1->S2->S3->S5->S1
B. S0->S1->S2->S3->S5->S1->S2->S3
C. S0->S1->S2~>S3->S4
D. S0->S1 ->S2->S3->S5->S3->S4

Correct Answer:D
According to the ISTQB Certified Tester Foundation Level (CTFL) v4.0, the life cycle of a defect typically follows a sequence from its discovery to its closure. In the provided figure, it starts withS0 (New), moves to S1 (Assigned), then to S2 (Resolved), followed by S3 (Verified). If the defect is not fixed, it can be Re-opened (S5) and goes back for verification (S3). Once verified, it is Closed (S4).

Question 39

The following diagram displays the logical dependencies between requirements and the individual requirement priorities. For example, "R2->R3" means that R3 is dependent on R2. Priority is indicated by the number next to the letter ??P" i.e. P1 has a higher priority than P2.

Which one of the following options best describes the test execution sequence using both requirement dependency and priority

A. R2. R1, R3. R4. R5, R6. R7, R8.
B. R1, R2, R3, R4, R5, R6, R7, R8.
C. R2, R4. R8, R5, R1, R6, R3, R7.
D. . R2, R1,R3,R7,R6,R5,R4,R8.

Correct Answer:D
The correct test execution sequence should consider both the dependencies between the requirements and their priorities. According to the diagram, the sequence begins with R2 (P1) as it is a prerequisite for R3 (P4). Then R1 (P3) can be tested. R3 follows as it depends on R2. Next, R7 (P4) should be tested before R6 (P3) and R5 (P2), as indicated by their dependencies. Finally, R4 (P1) and R8 (P1) can be tested. Therefore, the best sequence is R2, R1, R3, R7, R6, R5, R4, R8.Reference:ISTQB CTFL Syllabus V4.0,

Question 40

Which of the following statements about white-box test techniques is true?

A. Achieving full statement coverage and full branch coverage for a software product means that such software product has been fully tested and there are no remaining bugs within the code
B. Code-related white-box test techniques are not required to measure the actual code coverage achieved by black-box testing, as code coverage can be measured using the coverage criteria associated with black-box test techniques
C. Branch coverage is the most thorough code-related white-box test technique, and therefore applicable standards prescribe achieving full branch coverage at the highest safety levels for safety-critical systems
D. Code-related white-box test techniques provide an objective measure of coverage and can be used to complement black-box test techniques to increase confidence in the code

Correct Answer:D
This answer is correct because code-related white-box test techniques are test design techniques that use the structure of the code to derive test cases. They provide an objective measure of coverage, such as statement coverage, branch coverage, or path coverage, which indicate how much of the code has been exercised by the test cases. Code-related white-box test techniques can be used to complement black-box test techniques, which are test design techniques that use the functional or non-functional requirements of the system or component to derive test cases. By combining both types of techniques, testers can increase their confidence in the code and find more
defects. References: ISTQB Glossary of Testing Terms v4.0, ISTQB Foundation Level
