NEW QUESTION # 160
Which of the following statements is TRUE'?
Answer: B
Explanation:
Statement D is correct. According to the ISTQB CTFL syllabus, both black-box test techniques (which focus on testing without internal knowledge of the application) and experience-based test techniques (which rely on testers' experience and intuition) can be applied to both functional and non-functional testing. Functional testing is concerned with what the system does, whereas non-functional testing looks at how the system performs under certain conditions. These techniques are versatile and can be employed to address both these aspects.
NEW QUESTION # 161
An alphanumeric password must be between 4 and 7 characters long and must contain at least one numeric character, one capital (uppercase) letter and one lowercase letter of the alphabet.
Which one of the following sets of test cases represents the correct outcome of a two-value boundary value analysis applied to the password length? (Note: test cases are separated by a semicolon)
Answer: D
Explanation:
The correct outcome of a two-value boundary value analysis applied to the password length is the set of test cases represented by option D. Boundary value analysis is a test design technique that focuses on the values at the boundaries of an equivalence partition, such as the minimum and maximum values, or the values just above and below the boundaries. A two-value boundary value analysis uses two values for each boundary, one representing the valid value and one representing the invalid value. For example, if the valid range of values is from 4 to 7, then the two values for the lower boundary are 3 and 4, and the two values for the upper boundary are 7 and 8. The test cases in option D use these values for the password length, while also satisfying the other requirements of the password, such as containing at least one numeric character, one capital letter, and one lowercase letter. The test cases in option D are:
1RhT: a 4-character password that is valid
rSp53: a 5-character password that is valid
3N3e10: a 6-character password that is valid
8sBdby: an 8-character password that is invalid The test cases in the other options are incorrect, because they either use values that are not at the boundaries of the password length, or they do not meet the other requirements of the password. For example, the test cases in option A are:
1xA: a 3-character password that is invalid, but it does not contain a capital letter aB11: a 4-character password that is valid Pq1ZZab: a 7-character password that is valid
7iDD0a1x: an 8-character password that is invalid Reference: ISTQB Certified Tester Foundation Level (CTFL) v4.0 sources and documents:

NEW QUESTION # 162
The acceptance criteria associated with a user story:
Answer: C
Explanation:
The acceptance criteria associated with a user story are the conditions that must be met for the user story to be considered done and to deliver the expected value to the user. They are often written in different formats, such as rule-oriented, scenario-oriented, or table-oriented, depending on the nature and complexity of the user story. They represent an aspect of a user story referred to as confirmation, which is one of the so called "3 C's" of user stories. The other two aspects are card and conversation. Card refers to the concise and informal description of the user story, usually following the template: "As a [role], I want [feature], so that I can [benefit]". Conversation refers to the ongoing dialogue between the stakeholders and the team members to clarify and refine the user story and its acceptance criteria. Therefore, option C is the correct answer.
NEW QUESTION # 163
A typical objective of testing is to ensure that:
Answer: C
Explanation:
This answer is correct because a typical objective of testing is to ensure that a software has been tested using a combination of test techniques, such as black-box, white-box, or experience-based techniques, that are appropriate for the test objectives, test levels, and test types. Testing using a combination of test techniques can increase the effectiveness and efficiency of testing, as different techniques can target different aspects of the software quality, such as functionality, usability, performance, security, reliability, etc. Testing using a combination of test techniques can also reduce the risk of missing defects that could be detected by one technique but not by another.

NEW QUESTION # 164
An application is subjected to a constant load for an extended period of time as part of a performance test While running this test, the response time of the application steadily slows down, which results in a requirement not being met This slowdown is caused by a memory leak where the application code does not properly release some of the dynamically allocated memory when it is no longer needed. Which of the following statements is TRUE?
Answer: B
Explanation:
In software testing terminology, a failure is an observable deviation of the software from its expected behavior. A defect (or bug) is the cause of the failure in the software's code. In this case, the observed slowdown is the failure, while the underlying memory leak in the application code is the defect causing this failure. This distinction is clearly outlined in the ISTQB CTFL Syllabus v4.0, which differentiates between failures (observable issues) and defects (underlying issues in the code).
