You are responsible for applying the correct technique for a review of the requirements document for a project to develop a new software application. You identify the reviewers and the required roles, including the meeting leader, who is the requirements document author, and a separate role for a scribe. Additionally, you decide to take a relatively informal approach to the requirements review. The goal of the review is to find defects in the requirements document, such as omissions, Inconsistencies, and duplications. Another goal of the review is to improve the software application's usability and accessibility by considering the various stakeholders' viewpoints.
Which of the following statements BEST describes this scenario?

1. A. This scenario is using a pair review type and a perspective-based review technique
2. B. This scenario is using a walkthrough review type and a checklist-based review technique
3. C. This scenario is using a walkthrough review type and a perspective-based reviewtechnique
4. D. This scenario is using a pair review type and a checklist-based review technique

Correct Answer: C
This scenario is using a walkthrough review type and a perspective-based review technique. In a walkthrough, the author of the document leads the meeting and it typically includes a meeting leader and a scribe, as described. This type of review is informal, focuses on discussion, and often involves scenario-based reading of the document to understand different user perspectives (ISTQB Main Web).References:

4 equivalence classes are given for integer values:
0 < x <100
100<= x <= 200
200 < x < 500
x >= 500
Which of the following options represent correct set of data for valid equivalence class partitions?

1. A. 50; 100; 200. 1000
2. B. 0. 1.99, 100.200,201.499, 500;
3. C. 0.50; 100; 150.200.350.500;
4. D. 50; 100; 250; 1000

Correct Answer: C
The correct set of data for valid equivalence class partitions should include one value from each equivalence class, and no value from outside the range. Option C satisfies this condition, as it has one value from each of the four equivalence classes (50, 100, 250, 500). Option A has two values from the same equivalence class (100 and 200), option B has values outside the range (0 and 0.99), and option D has two values from the same equivalence class (1000 and 500).

Which of the following is NOT an experience-based technique?

1. A. Boundary value analysis.
2. B. Error guessing
3. C. Exploratory testing
4. D. Fault attack

Correct Answer: A
Boundary value analysis is not an experience-based technique, but rather a specification-based technique (also known as black-box technique). Experience-based techniques are techniques that rely on the tester’s knowledge and intuition to derive and select test cases based on their experience with similar systems, technologies, domains, risks, etc. Some examples of experience-based techniques are error guessing, exploratory testing, fault attack, checklist-based testing, etc. Specification-based techniques are techniques that rely on the tester’s analysis and interpretation of the requirements or specifications of the system under test to derive and select test cases based on some criteria or rules. Some examples of specification-based techniques are equivalence partitioning, boundary value analysis, decision table testing, state transition testing, etc. Verified References: A Study Guide to the ISTQB® Foundation Level 2018 Syllabus - Springer, page 31.

In which of the following cases you would NOT execute maintenance testing?

1. A. Retirement of the software or system
2. B. Modifications to a released software or system
3. C. Migration of the system data to a replacement system
4. D. Update to the Maintainability requirements during the development phase

Correct Answer: D
Maintenance testing is testing performed on a software product after delivery to correct defects or improve performance or other attributes. Maintenance testing can be triggered by various situations, such as modifications to a released software or system, migration of the system data to a replacement system, or retirement of the software or system. Maintenance testing is not executed when there is an update to the maintainability requirements during the development phase, as this is not a maintenance situation but rather a change request that should be handled by the development process.

Which of the following is an INCORRECT statement about the benefit of traceability between the test basis and test work products?

1. A. Traceability may be required by IT governance rules
2. B. Traceability may help evaluate the extent of test coverage
3. C. Traceability may allow testing to be auditable
4. D. Traceability may make it harder to understand the impact of changes

Correct Answer: D
The statement "Traceability may make it harder to understand the impact of changes" is incorrect. Traceability in testing actually facilitates understanding the impact of changes by linking test cases to requirements. This linkage helps ensure that any changes in the requirements are adequately reflected and verified in the test cases, thus supporting effective management of changes and maintaining the integrity of the system or product being developed (ISTQB not-for-profit association) (ISTQB Main Web).References:
