NEW QUESTION # 15
Which ONE of the following statements would you expect to be the MOST DIRECT advantage of the whole- team approach?

• A. Capitalizing on the combined skills of business representatives, testers, and developers working together to contribute to project success.
• B. Reducing the involvement of business representatives because of enhanced communication and collaboration between testers and developers.
• C. Having an automated build and test process, at least once a day, that detects integration errors early and quickly.
• D. Avoiding requirements misunderstandings that may not have been detected until dynamic testing when they are more expensive to fix.

Answer: A

Explanation:
The whole-team approach promotes collaboration among stakeholders (business representatives, developers, and testers) to ensure better quality and project success (A). This approach allows for early identification of issues, enhances shared responsibility, and improves software quality. Option C is a valid but indirect benefit, while options B and D do not directly describe the core advantage of the whole-team approach.

NEW QUESTION # 16
Which of the following statements about static testing and dynamic testing is true?

• A. Unlike dynamic testing, which focuses on detecting potential defects, static testing focuses on detecting failures which may be due to actual defects
• B. Both static testing and dynamic testing can be used to highlight issues associated with non-functional characteristics
• C. Static testing is usually much less cost-effective than dynamic testing
• D. Unlike dynamic testing, which can be also performed manually, static testing cannot be performed without specialized tools

Answer: B

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.

• A. In statement testing, the coverage items are executable statements. The aim is to design test cases that exercise statements in the code until an acceptable level of coverage is achieved, expressed as a percentage.
• B. In statement testing, the coverage items are decisions and statements. The aim is to design test cases that exercise statements in the code until an acceptable level of coverage is achieved, expressed as a percentage.
• C. In statement testing, the coverage items are branches, and the aim is to design test cases to exercise branches in the code until an acceptable level of coverage is achieved, expressed as a percentage.
• D. In statement testing, the coverage items are control flow transfers between branches. The aim is to design test cases to exercise branches in the code until an acceptable level of coverage is achieved, expressed as a percentage.

Answer: A

Explanation:
Statement testingaims to executeevery executable statementin the source code at least once.
* (D) is correctas statement testing ensuresmaximum statement execution.
* (A) describes branch testing, which focuses on flow transfers.
* (B) and (C) incorrectly mix decision testing and branch testing concepts.

NEW QUESTION # 18
The acceptance criteria associated with a user story:

• A. must be written in one of the two following formats: scenario-oriented or rule-oriented
• B. are often written in a rule-oriented format using the template referred to as "Given/When/Then"
• C. are often documented following in rule-oriented format using the following template: "As a [role], I want [feature], so that I can [benefit]"
• D. can be written in different formats and represent an aspect of a user story referred to as confirmation' of the so called "3 C's"

Answer: D

Explanation:
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 # 19
Which of the following is a test task that usually occurs during test implementation?

• A. Gather the metrics that are used to guide the test project
• B. Archive the testware for use in future test projects
• C. Find, analyze, and remove the causes of the failures highlighted by the tests
• D. Make sure the planned test environment is ready to be delivered

Answer: D

Explanation:
Explanation
A test task that usually occurs during test implementation is to make sure the planned test environment is ready to be delivered. The test environment is the hardware and software configuration on which the tests are executed, and it should be as close as possible to the production environment where the software system will operate. The test environment should be planned, prepared, and verified before the test execution, to ensure that the test conditions, the test data, the test tools, and the test interfaces are available and functional. The other options are not test tasks that usually occur during test implementation, but rather test tasks that occur during other test activities, such as:
Find, analyze, and remove the causes of the failures highlighted by the tests: This is a test task that usually occurs during test analysis and design, which is the activity of analyzing the test basis, designing the test cases, and identifying the test data. During this activity, the testers can use techniques such as root cause analysis, defect prevention, or defect analysis, to find, analyze, and remove the causes of the failures highlighted by the previous tests, and to prevent or reduce the occurrence of similar failures in the future tests.
Archive the testware for use in future test projects: This is a test task that usually occurs during test closure, which is the activity of finalizing and reporting the test results, evaluating the test process, and identifying the test improvement actions. During this activity, the testers can archive the testware, which are the test artifacts produced during the testing process, such as the test plan, the test cases, the test data, the test results, the defect reports, etc., for use in future test projects, such as regression testing, maintenance testing, or reuse testing.
Gather the metrics that are used to guide the test project: This is a test task that usually occurs during test monitoring and control, which is the activity of tracking and reviewing the test progress, status, and quality, and taking corrective actions when necessary. During this activity, the testers can gather the metrics, which are the measurements of the testing process, such as the test coverage, the defect density, the test effort, the test duration, etc., that are used to guide the test project, such as planning, estimating, scheduling, reporting, or improving the testing process.

NEW QUESTION # 20
Which ONE of the following is a CORRECT example of the purpose of a test plan?

• A. A testmanager decides to create a one page test plan for an agile project for communicating the broad activities and explaining why detailed test caseswillnot be written as mandated by the test policy.
• B. A test manager should always create a very simple test plan because the purpose of test plan is to ensure that there is documentation for the purpose of audits.
• C. A test plan is a good document to have for the agile projects because it helps the test manager assign tasks to different people
• D. A test lead decides to write a detailed test plan so that in future, in case of project failure responsibilities could be assigned to the right person

Answer: A

Explanation:
A test plan serves multiple purposes, such as defining the scope, approach, resources, and schedule of the testing activities. It also helps in communicating important information and managing stakeholder expectations. In agile projects, test plans might be concise to align with agile principles of simplicity and flexibility. A one-page test plan can effectively communicate broad activities and strategic decisions, such as not writing detailed test cases due to the project's agile nature. This approach ensures that essential information is conveyed without unnecessary documentation overhead, adhering to the agile manifesto's value of "working software over comprehensive documentation".

NEW QUESTION # 21
The acceptance criteria associated with a user story:

• A. must be written in one of the two following formats: scenario-oriented or rule-oriented
• B. are often written in a rule-oriented format using the template referred to as "Given/When/Then"
• C. are often documented following in rule-oriented format using the following template: "As a [role], I want [feature], so that I can [benefit]"
• D. can be written in different formats and represent an aspect of a user story referred to as confirmation' of the so called "3 C's"

Answer: D

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 # 22
An organization is working on updating test cases for a particular module of their software.
Sam updated a set of test cases yesterday and saved the new version on his PC.
Unfortunately, the hard disk of his PC crashed, and his work was lost.
The IT department of the organization restored the contents of his hard disk with the last available back-up - from the previous morning. However, the changes made by him yesterday were lost forever.
Which of the following tools, had it been used, would have prevented the loss of Sam's updates?

• A. Configuration Management Tool
• B. Test Execution tool
• C. Incident Management Tool
• D. Backup tool

Answer: A

Explanation:
A configuration management tool helps in maintaining and managing changes to software, including test cases. It ensures that changes are tracked and can be retrieved if needed. In this scenario, using a configuration management tool would have allowed Sam's updates to be stored in a central repository, preventing the loss of his work even if his PC's hard disk crashed.

NEW QUESTION # 23
Which of the following statements about white-box test techniques is true?

• A. 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
• 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. 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
• D. 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

Answer: A

Explanation:
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.

• D. C4

Answer: C

Explanation:
The decision table provides conditions and corresponding actions. For C2:
* The user is logged in (Yes).
* The user is not authorized to view the profile (No).
* The correct action should be not to display the profile (No) and to display an error message (Yes).
This matches the actions listed for C2, making it the correct condition with the proper actions.

NEW QUESTION # 25
Test automation allows you to:

• A. produce tests that are less subject to human errors
• B. demonstrate the absence of defects
• C. avoid performing exploratory testing
• D. increase test process efficiency by facilitating management of defects

Answer: A

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.

NEW QUESTION # 26
Which of the following statements about estimation of the test effort is WRONG?

• A. Effort estimate depends on the budget of the project.
• B. Effort estimate can be inaccurate because the quality of the product under tests is not known.
• C. Once the test effort is estimated, resources can be identified and a schedule can be drawn up.
• D. Experience based estimation is one of the estimation techniques.

Answer: A

Explanation:
* Effort estimate does not depend on the budget of the project, but rather on the scope, complexity, and quality of the software product and the testing activities1. Budget is a constraint that may affect the feasibility and accuracy of the effort estimate, but it is not a factor that determines the effort estimate. Effort estimate is the amount of work required to complete the testing activities, measured in terms of person-hours, person-days, or person-months2.
* The other options are correct because:
* A. Once the test effort is estimated, resources can be identified and a schedule can be drawn up, as they are interrelated aspects of the test planning process3. Resources are the people, tools, equipment, and facilities needed to perform the testing activities4. Schedule is the time frame and sequence of the testing activities, aligned with the project milestones and deadlines5.
* B. Effort estimate can be inaccurate because the quality of the product under tests is not known, as it affects the number and severity of the defects that may be found and the rework that may be needed to fix them6. Quality is the degree to which the software product satisfies the specified requirements and meets the needs and expectations of the users and clients7.
* D. Experience based estimation is one of the estimation techniques, which relies on the judgment and expertise of the testers and other project stakeholders to estimate the test effort based on similar projects or tasks done in the past. Experience based estimation can be useful when there is a lack of historical data, formal methods, or detailed information about the software product and the testing activities.

NEW QUESTION # 27
Which of the following statements about branch coverage is true?

• A. The minimum number of test cases needed to achieve full branch coverage, is usually lower than that needed to achieve full statement coverage
• B. Exercising at least one of the decision outcomes for all decisions within the code, ensures achieving full branch coverage
• C. If full branch coverage has been achieved, then all unconditional branches within the code have surely been exercised
• D. If full branch coverage has been achieved, then all combinations of conditions in a decision table have surely been exercised

Answer: B

Explanation:
Exercising at least one of the decision outcomes for all decisions within the code, ensures achieving full branch coverage, which is a test coverage criterion that requires that all branches in the control flow of the code are executed at least once by the test cases. A branch is a basic block of code that has a single entry point and a single exit point, and a decision is a point in the code where the control flow can take more than one direction, such as an if-then-else statement, a switch-case statement, a loop statement, etc. The decision outcomes are the possible paths that can be taken from a decision, such as the then branch or the else branch, the case branch or the default branch, the loop body or the loop exit, etc. The other statements are false, because:
* The minimum number of test cases needed to achieve full branch coverage, is usually higher than that needed to achieve full statement coverage, which is a test coverage criterion that requires that all executable statements in the code are executed at least once by the test cases. This is because branch coverage is a stronger criterion than statement coverage, as it implies statement coverage, but not vice versa. For example, a single test case can achieve full statement coverage for an if-then-else statement, but two test cases are needed to achieve full branch coverage, as both the then branch and the else branch need to be exercised.
* If full branch coverage has been achieved, then all unconditional branches within the code have not necessarily been exercised, as unconditional branches are branches that do not depend on any decision, and are always executed, such as a goto statement, a break statement, a return statement, etc.
Unconditional branches are not part of the branch coverage criterion, as they do not represent different paths in the control flow of the code. However, they are part of the statement coverage criterion, as they are executable statements in the code.
* If full branch coverage has been achieved, then all combinations of conditions in a decision table have not necessarily been exercised, as a decision table is a test design technique that represents the logical relationships between multiple conditions and their corresponding actions, in a tabular format. A decision table can have more combinations of conditions than the number of decision outcomes in the code, as each condition can have two or more possible values, such as true or false, yes or no, etc. For example, a decision table with four conditions can have 16 combinations of conditions, but the corresponding code may have only two decision outcomes, such as pass or fail. To exercise all combinations of conditions in a decision table, a stronger test coverage criterion is needed, such as condition combination coverage, which requires that all possible combinations of condition outcomes in the code are executed at least once by the test cases.

NEW QUESTION # 28
A company wants to reward each of its salespeople with an annual bonus that represents the sum of all the bonuses accumulated for every single sale made by that salesperson. The bonus for a single sale can take on the following four values: 3%, 5%, 7% and 10% (the percentage refers to the amount of the single sale). These values are determined on the basis of the type of customer (classified as "Basic" or "Premium") to which such sale was made, and on the amount of such sale classified into the following three groups G1, G2 and G3:
* [G1]: less than 300 euros
* [G2]: between 300 and 2000 euros
* [G3]: greater than 2000 euros
Which of the following is the minimum number of test cases needed to cover the full decision table associated with this scenario?

• A. 0
• B. 1
• C. 2
• D. 3

Answer: C

Explanation:
The minimum number of test cases needed to cover the full decision table associated with this scenario is 6. This is because the decision table has 4 conditions (type of customer and amount of sale) and 4 actions (bonus percentage). The conditions have 2 possible values each (Basic or Premium, and G1, G2 or G3), so the total number of combinations is 2 x 2 x 2 x 2 = 16. However, not all combinations are valid, as some of them are contradictory or impossible. For example, a sale cannot be both less than 300 euros and greater than 2000 euros at the same time. Therefore, we need to eliminate the invalid combinations and keep only the valid ones. The valid combinations are:
Type of customer
Amount of sale
Bonus percentage
Basic
G1
3%
Basic
G2
5%
Basic
G3
7%
Premium
G1
5%
Premium
G2
7%
Premium
G3
10%
These 6 combinations cover all the possible values of the conditions and actions, and they are the minimum number of test cases needed to cover the full decision table.

NEW QUESTION # 29
Which of the following statements is not correct?

• A. Identifying defects may be perceived as criticism against product
• B. Looking for defects in a system may require Ignoring system details
• C. Looking for defects in system requires professional pessimism and curiosity
• D. Testing is often seen as a destructive activity instead of constructive activity

Answer: B

Explanation:
Looking for defects in a system does not require ignoring system details, but rather paying attention to them and understanding how they affect the system's quality, functionality, and usability. Ignoring system details could lead to missing important defects or testing irrelevant aspects of the system.
Identifying defects may be perceived as criticism against product, especially by the developers or stakeholders who are invested in the product's success. However, identifying defects is not meant to be a personal attack, but rather a constructive feedback that helps to improve the product and ensure its alignment with the requirements and expectations of the users and clients.
Looking for defects in system requires professional pessimism and curiosity, as testers need to anticipate and explore the possible ways that the system could fail, malfunction, or behave unexpectedly. Professional pessimism means being skeptical and critical of the system's quality and reliability, while curiosity means being eager and interested in finding out the root causes and consequences of the defects.
Testing is often seen as a destructive activity instead of constructive activity, as it involves finding and reporting the flaws and weaknesses of the system, rather than creating or enhancing it. However, testing is actually a constructive activity, as it contributes to the system's improvement, verification, validation, and optimization, and ultimately to the delivery of a high-quality product that meets the needs and expectations of the users and clients.

NEW QUESTION # 31
Which of the following statements about retrospectives is true?

• A. During retrospectives, in addition to identifying relevant process improvements, participants should also consider how to implement these improvements and retain them based on the context of the project, such as the software development lifecycle
• B. Retrospectives can be very effective in identifying process improvements and can also be very efficient and cost-effective especially since, unlike reviews, they do not require any follow-up activities
• C. On Agile projects, well-conducted retrospectives at the end of each iteration can help the team reduce and sometimes even eliminate the need for daily stand-up meetings
• D. Only developers and testers should be involved in retrospectives, as involving people in other roles is very likely to prevent developers and testers from having open and constructive discussions that really help identify process improvements

Answer: A

Explanation:
Retrospectives are critical for continuous improvement in Agile projects. They involve not only identifying process improvements but also planning their implementation and ensuring they are retained, considering the specific context of the project, such as the software development lifecycle. This holistic approach ensures that improvements are practical and sustainable.

NEW QUESTION # 32
The four test levels used in ISTQB syllabus are:
1. Component (unit) testing
2. Integration testing
3. System testing
4. Acceptance testing
An organization wants to do away with integration testing but otherwise follow V-model. Which of the following statements is correct?

• A. It is allowed as organizations can decide on men test levels to do depending on the context of the system under test
• B. It is not allowed as organizations can't change the test levels as these are chosen on the basis of the SDLC (software development life cycle) model
• C. It is not allowed because integration testing is a very important test level and ignoring i: means definite poor product quality
• D. It is allowed because integration testing is not an important test level arc! can be dispensed with.

Answer: B

Explanation:
The V-model is a software development life cycle model that defines four test levels that correspond to four development phases: component (unit) testing with component design, integration testing with architectural design, system testing with system requirements, and acceptance testing with user requirements. The V-model emphasizes the importance of verifying and validating each phase of development with a corresponding level of testing, and ensuring that the test objectives, test basis, and test artifacts are aligned and consistent across the test levels. Therefore, an organization that wants to follow the V-model cannot do away with integration testing, as it would break the symmetry and completeness of the V-model, and compromise the quality and reliability of the software or system under test. Integration testing is a test level that aims to test the interactions and interfaces between components or subsystems, and to detect any defects or inconsistencies that may arise from the integration of different parts of the software or system. Integration testing is essential for ensuring the functionality, performance, and compatibility of the software or system as a whole, and for identifying and resolving any integration issues early in the development process. Skipping integration testing would increase the risk of finding serious defects later in the test process, or worse, in the production environment, which would be more costly and difficult to fix, and could damage the reputation and credibility of the organization. Therefore, the correct answer is D.
The other options are incorrect because:
* A. It is not allowed as organizations can decide on the test levels to do depending on the context of the system under test. While it is true that the choice and scope of test levels may vary depending on the context of the system under test, such as the size, complexity, criticality, and risk level of the system, the
* organization cannot simply ignore or skip a test level that is defined and required by the chosen software development life cycle model. The organization must follow the principles and guidelines of the software development life cycle model, and ensure that the test levels are consistent and coherent with the development phases. If the organization wants to have more flexibility and adaptability in choosing the test levels, it should consider using a different software development life cycle model, such as an agile or iterative model, that allows for more dynamic and incremental testing approaches.
* B. It is not allowed because integration testing is not an important test level and can be dispensed with.
This statement is false and misleading, as integration testing is a very important test level that cannot be dispensed with. Integration testing is vital for testing the interactions and interfaces between components or subsystems, and for ensuring the functionality, performance, and compatibility of the software or system as a whole. Integration testing can reveal defects or inconsistencies that may not be detected by component (unit) testing alone, such as interface errors, data flow errors, integration logic errors, or performance degradation. Integration testing can also help to verify and validate the architectural design and the integration strategy of the software or system, and to ensure that the software or system meets the specified and expected quality attributes, such as reliability, usability, security, and maintainability.
Integration testing can also provide feedback and confidence to the developers and stakeholders about the progress and quality of the software or system development. Therefore, integration testing is a crucial and indispensable test level that should not be skipped or omitted.
* C. It is not allowed because integration testing is a very important test level and ignoring it means definite poor product quality. This statement is partially true, as integration testing is a very important test level that should not be ignored, and skipping it could result in poor product quality. However, this statement is too strong and absolute, as it implies that integration testing is the only factor that determines the product quality, and that ignoring it would guarantee a poor product quality. This is not necessarily the case, as there may be other factors that affect the product quality, such as the quality of the requirements, design, code, and other test levels, the effectiveness and efficiency of the test techniques and tools, the competence and experience of the developers and testers, the availability and adequacy of the resources and environment, the management and communication of the project, and the expectations and satisfaction of the customers and users. Therefore, while integration testing is a very important test level that should not be skipped, it is not the only test level that matters, and skipping it does not necessarily mean definite poor product quality, but rather a higher risk and likelihood of poor product quality.

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?

• A. The final estimate is exactly 30 person hours because the technique uses the arithmetic mean of the three initial estimates as the final estimate
• B. The final estimate is between 22 person hours and 38 person hours
• C. The final estimate is between 6 person hours and 54 person hours
• D. The final estimate is exactly 30 person hours because the technique uses the initial most likely estimate as the final estimate

Answer: B

Explanation:
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 # 34
Which of the following is a test task that usually occurs during test implementation?

• A. Gather the metrics that are used to guide the test project
• B. Archive the testware for use in future test projects
• C. Find, analyze, and remove the causes of the failures highlighted by the tests
• D. Make sure the planned test environment is ready to be delivered

Answer: D

Explanation:
A test task that usually occurs during test implementation is to make sure the planned test environment is ready to be delivered. The test environment is the hardware and software configuration on which the tests are executed, and it should be as close as possible to the production environment where the software system will operate. The test environment should be planned, prepared, and verified before the test execution, to ensure that the test conditions, the test data, the test tools, and the test interfaces are available and functional. The other options are not test tasks that usually occur during test implementation, but rather test tasks that occur during other test activities, such as:
Find, analyze, and remove the causes of the failures highlighted by the tests: This is a test task that usually occurs during test analysis and design, which is the activity of analyzing the test basis, designing the test cases, and identifying the test data. During this activity, the testers can use techniques such as root cause analysis, defect prevention, or defect analysis, to find, analyze, and remove the causes of the failures highlighted by the previous tests, and to prevent or reduce the occurrence of similar failures in the future tests.
Archive the testware for use in future test projects: This is a test task that usually occurs during test closure, which is the activity of finalizing and reporting the test results, evaluating the test process, and identifying the test improvement actions. During this activity, the testers can archive the testware, which are the test artifacts produced during the testing process, such as the test plan, the test cases, the test data, the test results, the defect reports, etc., for use in future test projects, such as regression testing, maintenance testing, or reuse testing.
Gather the metrics that are used to guide the test project: This is a test task that usually occurs during test monitoring and control, which is the activity of tracking and reviewing the test progress, status, and quality, and taking corrective actions when necessary. During this activity, the testers can gather the metrics, which are the measurements of the testing process, such as the test coverage, the defect density, the test effort, the test duration, etc., that are used to guide the test project, such as planning, estimating, scheduling, reporting, or improving the testing process.

NEW QUESTION # 35
The fact that defects are usually not evenly distributed among the various modules that make up a software application, but rather their distribution tend to reflect the Pareto principle:

• A. is expressed by the testing principle referred to as 'Defects cluster together'
• B. is expressed by the testing principle referred to as 'Bug prediction'
• C. is a false myth
• D. is expressed by the testing principle referred to as Tests wear out'

Answer: A

Explanation:
The fact that defects are usually not evenly distributed among the various modules that make up a software application, but rather their distribution tend to reflect the Pareto principle, is expressed by the testing principle referred to as 'Defects cluster together'. This principle states that a small number of modules contain most of the defects detected, or that a small number of causes are responsible for most of the defects. This principle can be used to guide the test analysis and design activities, by prioritizing the testing of the most critical or risky modules, or by applying more rigorous test techniques to them. Therefore, option C is the correct answer.

NEW QUESTION # 36
A calculator software is used to calculate the result for 5+6.
The user noticed that the result given is 6.
This is an example of;

• A. Error
• B. Failure
• C. Mistake
• D. Fault

Answer: B

Explanation:
According to the ISTQB Glossary of Testing Terms, Version 4.0, 2018, page 18, a failure is "an event in which a component or system does not perform a required function within specified limits". In this case, the calculator software does not perform the required function of calculating the correct result for 5+6 within the specified limits of accuracy and precision. Therefore, this is an example of a failure.
The other options are incorrect because:
* A mistake is "a human action that produces an incorrect result" (page 25). A mistake is not an event, but an action, and it may or may not lead to a failure. For example, a mistake could be a typo in the code, a wrong assumption in the design, or a misunderstanding of the requirement.
* A fault is "a defect in a component or system that can cause the component or system to fail to perform its required function" (page 16). A fault is not an event, but a defect, and it may or may not cause a failure. For example, a fault could be a logical error in the code, a missing specification in the design, or a contradiction in the requirement.
* An error is "the difference between a computed, observed, or measured value or condition and the true, specified, or theoretically correct value or condition" (page 15). An error is not an event, but a difference, and it may or may not result in a failure. For example, an error could be a rounding error in the calculation, a measurement error in the observation, or a deviation error in the condition.

NEW QUESTION # 37
Which of the following lists factors That contribute to PROJECT risks?

• A. poor software quality characteristics; software does not perform its intended functions.
• B. skill and staff shortages; problems in defining the right requirements, contractual issues.
• C. problems in defining the right requirements; contractual issues; poor software quality characteristics.
• D. skill and staff shortages; software does not perform its intended functions; problems in defining the right requirements.

Answer: B

Explanation:
Project risks are the uncertainties or threats that may affect the project objectives, such as scope, schedule, cost, and quality. According to the ISTQB Certified Tester Foundation Level (CTFL) v4.0 syllabus, some of the factors that contribute to project risks are:
* Skill and staff shortages: This factor refers to the lack of adequate or qualified human resources to perform the project tasks. This may result in delays, errors, rework, or low productivity.
* Problems in defining the right requirements: This factor refers to the difficulties or ambiguities in eliciting, analyzing, specifying, validating, or managing the requirements of the project. This may result in misalignment, inconsistencies, gaps, or changes in the requirements, affecting the project scope and quality.
* Contractual issues: This factor refers to the challenges or disputes that may arise from the contractual agreements between the project parties, such as clients, suppliers, vendors, or subcontractors. This may result in legal, financial, or ethical risks, affecting the project delivery and satisfaction.
The other options are not correct because they list factors that contribute to PRODUCT risks, not project risks.
Product risks are the uncertainties or threats that may affect the quality or functionality of the software product or system. Some of the factors that contribute to product risks are:
* Poor software quality characteristics: This factor refers to the lack of adherence or compliance to the quality attributes or criteria of the software product or system, such as reliability, usability, security, performance, or maintainability. This may result in defects, failures, or dissatisfaction of the users or stakeholders.
* Software does not perform its intended functions: This factor refers to the deviation or discrepancy between the expected and actual behavior or output of the software product or system. This may result in errors, faults, or malfunctions of the software product or system.
