ISQI ISTQB Certified Tester Foundation Level (CTFL) v4.0 Sample Questions (Q115-Q120):
NEW QUESTION # 115
Which ONE of the following options is aPRODUCT riskand NOT aPROJECT risk?
Answer: C
Explanation:
Product risksare risks thatimpact the quality or functionality of the software, whereasproject risksaffect theprocess, resources, or timeline.
* (A) is correctbecause incorrect calculations impact software correctness.
* (B), (C), and (D) are project risksas they relate toteam coordination, staffing, and schedulingrather than software defects.
Identifyingproduct risksearlyimproves defect detection and ensures better coverage for high-risk areas.

NEW QUESTION # 116
Which of the following statements about static testing and dynamic testing is true?
Answer: A
Explanation:
This answer is correct because static testing and dynamic testing are both types of testing that can be used to highlight issues associated with non-functional characteristics, such as usability, performance, security, reliability, etc. Static testing is a type of testing that involves the analysis of software work products, such as requirements, design, code, or test cases, without executing them. Dynamic testing is a type of testing that involves the execution of software work products, such as code or test cases, using inputs and verifying outputs. Both static testing and dynamic testing can be applied to different test levels and test types, and can use different test techniques and tools, to evaluate the non-functional characteristics of the software product.

2.2.1.1, Section 2.2.1.2
NEW QUESTION # 117
Consider the following examples of risks identified in different software development projects:
[I]. The contrast color ratio for both normal text and large text of a website does not comply with the applicable accessibility guidelines, making itdifficult for many users to read the content on the pages
[II]. A development vendor fails to deliver their software system on time, causing significant delays to system integration testing activities that havebeen planned as part of a development project for a system of systems
[III]. People in the test team do not have sufficient skills to automate tests at the test levels required by the test automation strategy which does notallow production of an effective regression test suite
[IV]. In a web application, data from untrusted sources is not subject to proper input validation, making the applicationvulnerable to several securityattacks Which of the following statements is true?
Answer: C
Explanation:
Explanation
This answer is correct because product risks are risks that affect the quality of the software product, such as defects, failures, or non-compliance with requirements or standards. Project risks are risks that affect the project's schedule, budget, resources, or scope, such as delays, cost overruns, skill gaps, or scope changes. In this case, [I] and [IV] are product risks, as they relate to the accessibility and security of the software product, which are quality attributes. [II] and [III] are project risks, as they relate to the delivery time and the test automation skills of the test team, which are project factors.

NEW QUESTION # 118
Following a risk-based testing approach you have designed 10 tests to cover a product risk with a high-risk level. You want to estimate, adopting the three-point test estimation technique, the test effort required to reduce the risk level to zero by executing those 10 tests. You made the following three initial estimates:
* most optimistic = 6 person hours
* most likely = 30 person hours
* most pessimistic = 54 person hours
Based only on the given information, which of the following answers about the three-point test estimation technique applied to this problem is true?
Answer: A
Explanation:
The three-point test estimation technique is a method of estimating the test effort based on three initial estimates: the most optimistic, the most likely, and the most pessimistic. The technique uses a weighted average of these three estimates to calculate the final estimate, which is also known as the expected value. The formula for the expected value is:
Expected value = (most optimistic + 4 * most likely + most pessimistic) / 6 Using the given values, the expected value is:
Expected value = (6 + 4 * 30 + 54) / 6 Expected value = 30 person hours However, the expected value is not the only factor to consider when estimating the test effort. The technique also calculates the standard deviation, which is a measure of the variability or uncertainty of the estimates. The formula for the standard deviation is:
Standard deviation = (most pessimistic - most optimistic) / 6
Using the given values, the standard deviation is:
Standard deviation = (54 - 6) / 6 Standard deviation = 8 person hours
The standard deviation can be used to determine a range of possible values for the test effort, based on a certain level of confidence. For example, using a 68% confidence level, the range is:
Expected value ± standard deviation
Using the calculated values, the range is:
30 ± 8 person hours
Therefore, the final estimate is between 22 person hours and 38 person hours, which is option A.

NEW QUESTION # 119
Test automation allows you to:
Answer: B
Explanation:
Explanation
Test automation allows you to produce tests that are less subject to human errors, as they can execute predefined test scripts or test cases with consistent inputs, outputs, and expected results. Test automation can also reduce the manual effort and time required to execute repetitive or tedious tests, such as regression tests, performance tests, or data-driven tests. Test automation does not demonstrate the absence of defects, as it can only verify the expected behavior of the system under test, not the unexpected or unknown behavior. Test automation does not avoid performing exploratory testing, as exploratory testing is a valuable technique to discover new information, risks, or defects that are not covered by automated tests. Test automation does not increase test process efficiency by facilitating management of defects, as defect management is a separate activity that involves reporting, tracking, analyzing, and resolving defects, which may or may not be related to automated tests.
