Answer: A
Explanation:
Explanation
Agile software development is a term that encompasses a group of software development methodologies that are based on iterative incremental development, where requirements and solutions evolve through collaboration between self-organizing cross-functional teams. Agile methods promote adaptive planning, evolutionary development and delivery, a time-boxed iterative approach, and encourage rapid and flexible response to change. Some examples of agile methods are Scrum, Extreme Programming (XP), Kanban, and Lean Software Development. References:

Which statement about an Agile task board is CORRECT?
- A. It provides detailed visual representation of the whole team's status.
- B. It is a detailed visual representation of the status of testing.
- C. It is updated once at the end of each iteration.
- D. Only "in progress" tasks are shown on the task board.
Answer: A
Explanation:
Explanation
An Agile task board is a visual framework to display and sync up on the tasks moving between production steps. It is usually applied to the two most popular Agile development frameworks - Kanban and Scrum. Used by software developers and project managers, an Agile board helps manage workloads in a flexible, transparent, and iterative way1. An Agile task board provides a detailed visual representation of the whole team's status, showing which tasks remain to be started, which are in progress, and which are done. It also helps to track the progress of the current sprint, identify bottlenecks, and facilitate collaboration and communication among team members2. References:

NEW QUESTION # 25
Why is regression of software a high risk in agile projects?
- A. Test automation can cause regression of software in the test environment.
- B. Test-driven development means that existing functionality is not considered.
- C. Regression is built into software as a safeguard against unexpected failures.
- D. There is code churn due to change in business needs over several sprints.
Answer: D
Explanation:
Explanation
Regression of software is the risk that a change in one part of the software causes a defect in another part of the software that was previously working correctly. Regression of software is a high risk in agile projects because there is code churn due to change in business needs over several sprints. Code churn is the amount of code that is added, modified, or deleted in a software project over time. Code churn can indicate the volatility and complexity of the software, and the frequency and magnitude of the changes. In agile projects, code churn can be high because the business needs and the user requirements can change rapidly and frequently over several sprints, which are short iterations of development and testing. This means that the software is constantly evolving and adapting to the changing needs, and that the existing functionality and quality may be affected by the new or modified code. Therefore, regression of software is a high risk in agile projects, and it requires effective testing strategies and techniques to prevent, detect, and fix the regression defects.

NEW QUESTION # 28
What is the main benefit of the Test Pyramid?
- A. It acts as a metric for testing progress.
- B. It means testing is involved early in the development cycle.
- C. It shows complexity of testing activities.
- D. It helps in evaluating the amount of test cases needed.
Answer: D
Explanation:
Explanation
The Test Pyramid is a model for organizing tests in a way to make the process of testing faster, efficient and cost-effective. This model focusses on getting maximum functional testing getting covered by faster and less brittle tests like Unit and API tests1. The main benefit of the Test Pyramid is that it helps in evaluating the amount of test cases needed for each level of testing. The Test Pyramid suggests that the number of test cases should decrease as we move up the pyramid, from unit tests to integration tests to end-to-end tests. This is because unit tests are more granular, isolated, and easy to write and maintain, while end-to-end tests are more complex, dependent, and brittle. The Test Pyramid also helps in balancing the test coverage and the test execution time, as unit tests provide high coverage and low execution time, while end-to-end tests provide low coverage and high execution time. By following the Test Pyramid, teams can optimize their testing efforts and resources, and ensure that they have a sufficient and effective test suite for their software. References:

NEW QUESTION # 29
Which of the following statements about Agile retrospectives is CORRECT?
- A. During Agile retrospectives, testers should be encouraged to provide constructive suggestions only on non-testing activities.
- B. In an Agile retrospective the moderator can encourage and make sure that good practices are kept by the team, by asking what the team is doing well.
- C. Unlike working sessions or meetings held in non-Agile projects, Agile retrospectives do not require follow-up activities.
- D. Agile retrospectives should be focused mainly on impediments that are outside the control of the team because these issues are more challenging.
Answer: B
Explanation:
Explanation
An Agile retrospective is a regular meeting where the team reflects on their work process and identifies the areas for improvement12. The following statements about Agile retrospectives are correct12:
During Agile retrospectives, testers should be encouraged to provide constructive suggestions on both testing and non-testing activities, as testing is an integral part of the Agile team and testers can contribute to the overall quality of the product and the process.
In an Agile retrospective, the moderator can encourage and make sure that good practices are kept by the team, by asking what the team is doing well. This helps to reinforce the positive aspects of the team's work and to appreciate the team members' efforts and achievements.
Agile retrospectives should be focused mainly on impediments that are within the control of the team because these issues are more actionable and can be resolved by the team. Impediments that are outside the control of the team should also be discussed, but they may require the involvement of other stakeholders or external parties to be addressed.
The following statement about Agile retrospectives is incorrect12:
Unlike working sessions or meetings held in non-Agile projects, Agile retrospectives do require follow-up activities. The team should agree on the action items that result from the retrospective and assign them to the responsible team members. The team should also monitor the progress and effectiveness of the action items in the next iteration and review them in the next retrospective.
Therefore, the correct answer is B, as it is the only statement that is correct about Agile retrospectives. References: ISTQB Foundation Level Agile Tester Extension Syllabus1, page 24; ISTQB Agile Tester Sample Exam2,
NEW QUESTION # 30
Iteration planning for Sprint 5 of your current project is complete. The plan for the sprint is to increase performance of the system, which of the following acceptance criteria would you expect for Sprint 5?
1) User access for all roles has been validated.
2) A static analysis tool has been executed for all code.
3) 100% of the existing regression test suite has passed.
4) System is responding in less than 3 seconds, 90% of the time.
5) A new version of internet Explorer has been included.
- A. 2, 5
- B. 4, 5
- C. 1, 3
- D. 3, 4
Answer: D
Explanation:
Explanation
The acceptance criteria for a sprint are the conditions that must be met for the user stories to be considered done and deliver value to the customer1. The acceptance criteria should be specific, measurable, achievable, relevant, and testable2. In this case, the plan for the sprint is to increase performance of the system, so the acceptance criteria should reflect that goal. Therefore, the acceptance criteria that would be expected for Sprint
5 are:
100% of the existing regression test suite has passed. This criterion ensures that the system has not introduced any new defects or broken any existing functionality while improving performance3.
System is responding in less than 3 seconds, 90% of the time. This criterion defines a clear and quantifiable performance target that can be verified by testing4.
The other options are not relevant or appropriate acceptance criteria for Sprint 5:
User access for all roles has been validated. This criterion is not related to the performance of the system, but rather to the security or functionality of the system. It might be an acceptance criterion for a different sprint or user story, but not for Sprint 55.
A static analysis tool has been executed for all code. This criterion is not a customer
NEW QUESTION # 31
Which tasks are typically performed by a tester on an Agile project?
1) Implementing test strategy.
2) Documenting business requirements.
3) Measuring and reporting test coverage.
4) Coaching development team in relevant aspects of testing.
5) Executing test-driven development tests.
- A. 1, 3, 4
- B. 2, 4, 5
- C. 2, 5
- D. 1, 3
Answer: A
Explanation:
Explanation
A tester on an Agile project typically performs the following tasks12:
Implementing test strategy: A tester helps to define and implement the test strategy for the Agile project, which includes the test approach, test levels, test types, test techniques, test tools, test environment, test data, test metrics, and test documentation.
Measuring and reporting test coverage: A tester measures and reports the test coverage of the product features and quality attributes, such as functionality, usability, performance, security, etc. Test coverage can be expressed in terms of test cases, test scenarios, test sessions, test conditions, test data, code, etc.
Coaching development team in relevant aspects of testing: A tester coaches the development team in relevant aspects of testing, such as test design, test execution, test automation, test-driven development, behavior-driven development, exploratory testing, etc. A tester also helps the development team to improve their testing skills and practices.
The following tasks are not typically performed by a tester on an Agile project:
Documenting business requirements: Business requirements are usually documented by the product owner or the business analyst, not by the tester. The tester may review and provide feedback on the business requirements, but the tester is not responsible for documenting them.
Executing test-driven development tests: Test-driven development tests are usually executed by the developers, not by the tester. The tester may assist the developers in creating and reviewing the test-driven development tests, but the tester is not responsible for executing them.
Therefore, the correct answer is C, as it contains the tasks that are typically performed by a tester on an Agile project. References: ISTQB Foundation Level Agile Tester Extension Syllabus1, pages 14-15, 18-19, 22-23; ISTQB Agile Tester Sample Exam2, question 17.

NEW QUESTION # 33
User Story: As a user I want to be able to calculate tax percentage based on amount of income.
What is the best black box test design technique for verifying the accuracy of this user story?
- A. Statement testing - test all statements in income calculation.
- B. User story testing - test that the user can enter an income amount and get a result.
- C. Equivalence partitioning - test with low, medium and high income.
- D. State transition testing - test all states of income entry.
Answer: C
Explanation:
Explanation
The best black box test design technique for verifying the accuracy of this user story is equivalence partitioning. Equivalence partitioning is a technique that divides the input domain of a system into classes or groups that are expected to behave similarly. By testing one value from each class, the tester can reduce the number of test cases while still achieving good coverage. In this case, the input domainof the system is the amount of income, which can be divided into classes based on the tax percentage applied to different income ranges. For example, if the tax percentage is 10% for income below 10,000, 20% for income between 10,000 and 20,000, and 30% for income above 20,000, then the equivalence classes are: low income (<10,000), medium income (10,000-20,000), and high income (>20,000). By testing one value from each class, such as
5,000, 15,000, and 25,000, the tester can verify that the system calculates the correct tax percentage for each income range. This technique is more efficient and effective than testing all possible values of income, or testing only one value of income, or testing the states of income entry, or testing the statements in income calculation.

NEW QUESTION # 34
Which of the following statements about the benefits of the Agile processes promoting early and frequent feedback is NOT true?
- A. Early and frequent feedback enables the team to deliver the features that represent the highest business value to the customer first.
- B. Feedback from well-conducted Agile retrospectives can be used to positively affect the development process over the course of the next iteration.
- C. In Agile projects where feedback is provided early and frequently, defects and incorrect requirements are caught earlier and those problems can be fixed faster.
- D. Increasing the frequency of feedback and communication between all the stakeholders involved in Agile projects eliminates all communication problems.
Answer: D
Explanation:
Explanation
The Agile processes promote early and frequent feedback from the customers, users, testers, developers, and other stakeholders involved in the project. This feedback helps to ensure that the product meets the expectations and needs of the customers and users, and that the development process is continuously improved and adapted to the changing requirements and environment. However, increasing the frequency of feedback and communication does not eliminate all communication problems, as there may still be issues such as misunderstandings, misinterpretations, conflicts, or cultural differences that need to be resolved. Therefore, the statement D is not true, as it implies that communication problems are completely avoided by the Agile processes.

Your organization has recently changed to a SCRUM agile framework.Which of the following is an important organizational and behavioral best practice for a tester in the SCRUM team that should have also been practiced when using the sequential model?
- A. Credibility means that the tester must share information with the stakeholders about the test process so that they find the selected test strategy and testing activities trustworthy.
- B. Resilient testing means that the testing process is capable of dealing with rapid changes throughout the development process with test plans being updated during each iteration.
- C. Co-located teamwork means that all team members, including developers and testers, must sit together in the same office, so they can quickly communicate face-to-face.
- D. Cross-functional teamwork means that all team members contribute to testing in various ways. For example, involving people with the test strategy, test planning and execution as well as test reporting.
Answer: D

- B. 2, 4, 5
- C. 1, 2, 5
- D. 2, 3, 4
Answer: A
Explanation:
Explanation
A test charter is a document that describes the scope, objective, and approach of an exploratory testing session.
It is used mainly in exploratory tests to guide the tester's actions and record the findings. A test charter may make reference to user stories, requirements, risks, or other sources of information that are relevant to the testing mission. A test charter also contains notes taken during a test session, such as test ideas, test results, bugs, issues, and observations. A test charter is not used to monitor a test process, as it is not a formal metric or report. It is also not used to outline the company test policy, as it is specific to a particular test session and context.

NEW QUESTION # 39
Which of the following would provide the MOST independence for testers working with agile teams?
- A. Testers from an independent test team are assigned to the Agile team at the beginning of the project, returning for re-assignment to a new agile team.
- B. Testers from an independent test team are assigned on-demand for the final days of each sprint.
- C. Testers from an independent test team who do not get involved with the Agile team, but are assigned to do System Testing once all sprints are completed.
- D. Testers are fully embedded in each Agile team to perform many of the testing tasks.
Answer: C
Explanation:
Explanation
Independence in testing is the degree of separation between the person who tests something and the person who developed it. Independence can help to reduce bias, increase objectivity, and provide different viewpoints. However, independence also has some drawbacks, such as increased communication overhead, reduced collaboration, and delayed feedback. In agile projects, testers are usually embedded in the agile teams to perform many of the testing tasks, such as unit testing, integration testing, acceptance testing, etc. This provides a high level of collaboration and fast feedback, but also reduces the independence of the testers.
Testers from an independent test team who do not get involved with the agile team, but are assigned to do System Testing once all sprints are completed, would provide the most independence for testers working with agile teams. However, this would also introduce many disadvantages, such as lack of alignment with the agile principles, loss of context and domain knowledge, delayed defect detection and resolution, and increased risk of missing customer expectations.
