NEW QUESTION # 38
Consider the following testing levels:
1) Component Testing
2) Integration Testing
3) System Testing
4) Acceptance Testing
Which of the following statements is true?
- A. All the testing levels are applicable to V-model for software development.
Only acceptance testing is applicable for iterative models. - B. All testing levels are applicable, independent of which software development life-cycle process (V-model. iterative, incremental) is used.
- C. Integration and system testing are applicable when V-model is used.
Component and acceptance testing are applicable when iterative development models are used. - D. Acceptance testing is applicable for all software development models.
Component and system testing are applicable only for the V-model.
Answer: B
Explanation:
All testing levels are applicable, independent of which software development life-cycle process (V-model, iterative, incremental) is used. Testing levels are defined based on the scope and objectives of testing, not on the software development model. Component testing, integration testing, system testing and acceptance testing are common testing levels that can be applied to any software development model, as long as they are planned and executed properly. The V-model is a software development model that emphasizes the relationship between each development phase and its corresponding testing phase. Iterative and incremental models are software development models that divide the development process into smaller cycles or iterations, where each iteration produces a working version of the software that can be tested and evaluated.

III Preparation before the review meeting is part of informal reviews
IV Management rarely participates in technical review meetings
- A. I, II
- B. I, IV
- C. II, Ill
- D. III, IV
Answer: B
Explanation:
The following statements about reviews are true:
I) In walkthroughs the review meeting is typically led by the author. A walkthrough is a type of review that has a predefined objective and agenda but no formal process or roles. A walkthrough is typically led by the author of the work product under review, who guides the participants through a scenario and solicits feedback.
IV) Management rarely participates in technical review meetings. A technical review is a type of review that has a predefined objective and agenda but no formal process or roles. A technical review is typically performed by peers with technical expertise in order to evaluate technical aspects of a work product. Management rarely participates in technical review meetings, as they may not have sufficient technical knowledge or skills to contribute effectively. The following statements about reviews are false:
II) Inspection is characterized by an open-ended review meeting. An inspection is a type of review that follows a defined process with formal entry and exit criteria and roles and responsibilities for participants. An inspection is characterized by a structured review meeting with a fixed duration and agenda.
III) Preparation before the review meeting is part of informal reviews. Preparation before the review meeting is part of formal reviews, such as inspections or technical reviews. Preparation involves checking
NEW QUESTION # 40
Which are the MAIN goals of risk management in a software project?
- A. To increase focus on preventative processes and to increase satisfaction for the testers.
- B. To control contractual problems and minimize the impacts of company policies.
- C. To increase the success probability for the project regardless of costs.
- D. To reduce the probability of undesired situations and to reduce the effect of potential impact.
Answer: D
Explanation:
Risk management is a process that identifies, analyzes, evaluates and mitigates risks in a software project. Risks are factors that may negatively affect the quality, schedule, budget or scope of a software project. The main goals of risk management in a software project are to reduce the probability of undesired situations and to reduce the effect of potential impact. This can be achieved by applying various strategies, such as avoidance, transfer, reduction or acceptance. Risk management does not aim to increase the success probability for the project regardless of costs, as this may not be feasible or realistic. Risk management does not aim to increase focus on preventative processes and to increase satisfaction for the testers, as these are secondary or indirect outcomes. Risk management does not aim to control contractual problems and minimize the impacts of company policies, as these are specific types of risks that may not apply to all projects.

NEW QUESTION # 41
Which of the following statements about independent testing is WRONG?
- A. Independent testing is necessary because developers don't know any testing.
- B. Independent test teams may find other types of detects than developers who are familiar with the system's structure.
- C. A certain degree of independence makes the tester more effective at finding defects.
- D. Independent testing is best suited for the system test level.
Answer: A
Explanation:
Independent testing is testing performed by a person or group that is independent of the development team. Independent testing can have various degrees of independence, ranging from testers who are part of the same organization as developers to testers who are external contractors or consultants. Independent testing can have various benefits, such as reducing bias, increasing objectivity, improving quality, or providing different perspectives. Independent testing is not necessary because developers don't know any testing, as this is a wrong and disrespectful statement. Developers can perform various types of testing, such as unit testing, component testing, or integration testing. However, independent testing can complement developer testing by providing additional levels of verification and validation, such as system testing, acceptance testing, or non-functional testing.

NEW QUESTION # 42
Which of the following is the most important task of a typical test leader?
- A. To set up the test environment.
- B. To coordinate the test strategy with project managers.
- C. To prepare and acquire test data.
- D. To automate tests.
Answer: B
Explanation:
The most important task of a typical test leader is to coordinate the test strategy with project managers. The test strategy is a high-level document that defines the general approach and objectives of testing for a project or an organization. The test leader is responsible for defining, documenting, communicating, and implementing the test strategy in alignment with the project goals and constraints. The test leader also needs to coordinate with project managers and other stakeholders to ensure that the test strategy is feasible, effective, and efficient. The other options are not the most important tasks of a typical test leader. To automate tests is a task of a test automation engineer or a test automation specialist. To prepare and acquire test data is a task of a test analyst or a test engineer. To set up the test environment is a task of a test environment manager or a test environment specialist.

NEW QUESTION # 43
Software was found lo take much more time than the stated requirement of less than one second to save a file. Upon investigation it was found that there was an unnecessary check inside a loop which was slowing down the file-save operation. The software not being able to meet the desired response time is an example of
- A. Defect
- B. Failure
- C. Error
- D. It is not a defect
Answer: B
Explanation:
A failure is an event in which a component or system does not perform a required function within specified limits. A failure is observable by the software users or other stakeholders. A failure is caused by one or more defects in the software. In this case, the software not being able to meet the desired response time is an example of a failure, as it deviates from the stated requirement and affects the user experience. It is not a defect, which is a flaw in the software that causes the failure. It is not an error, which is a human action that produces an incorrect result. It is not a non-defect, as it clearly violates a specified requirement. Verified Reference: [A Study Guide to the ISTQB Foundation Level 2018 Syllabus - Springer], Chapter 1, page 4.
NEW QUESTION # 44
Which of the following is NOT a product risk?
- A. Failure-prone software is delivered
- B. Poor software usability
- C. Problems in defining the right requirements
- D. Software does not perform the intended functions
Answer: C
Explanation:
Problems in defining the right requirements is not a product risk, but rather a project risk. A product risk is a risk that affects the quality or performance of the software product itself, such as poor usability, failure-prone functionality, security vulnerabilities, compatibility issues, etc. A project risk is a risk that affects the management or delivery of the software project itself, such as unrealistic schedule, insufficient resources, unclear scope, changing requirements, etc. The other options are examples of product risks, as they relate to the software product's characteristics or features.

NEW QUESTION # 45
A test engineer finds a defect while testing. After the developer has fixed the defect, the test engineer decides to re-run a complete section of the tests. Which of the following is correct?
- A. The test engineer should re-run the tests, because the defect shows that the test cases need to be updated.
- B. The lest engineer should not re-run the tests, as they have already been run, and results recorded.
- C. The test engineer should re-run the tests, in order to ensure that new defects have not been introduced by the fix.
- D. The test engineer should not re-run the tests, they should be part of the developer tests.
Answer: C
Explanation:
The test engineer should re-run the tests, in order to ensure that new defects have not been introduced by the fix. This is also known as regression testing, which is a type of testing that verifies that previously tested software still performs correctly after a change. Regression testing helps to detect any side effects or unintended consequences of a fix or a modification. The other options are incorrect reasons for re-running the tests. The test engineer should not re-run the tests, as they have already been run, and results recorded, because this ignores the possibility of new defects caused by the fix. The test engineer should not re-run the tests, they should be part of the developer tests, because this assumes that developer tests are sufficient and reliable, which may not be true. The test engineer should not re-run the tests, because the defect shows that the test cases need to be updated, because this does not address the impact of the fix on other test cases or functionalities.

NEW QUESTION # 46
How can testing contribute to higher quality?
- A. Testing ensures that remaining defects are documented.
- B. Testing eliminates the risk with software.
- C. Testing help to measure the quality of software.
- D. Testing removes errors in the software.
Answer: C
Explanation:
Testing can contribute to higher quality by helping to measure the quality of software. Quality is defined as the degree to which a component or system satisfies specified requirements and customer or user needs and expectations. Testing is a process of evaluating a component or system by applying inputs and observing outputs, and comparing them with expected results. Testing can help to measure the quality of software by providing information on its functionality, performance, usability, security, reliability, etc. Testing can also help to identify and report defects in software, which can lead to improvement actions and quality assurance activities. The other options are not accurate descriptions of how testing can contribute to higher quality. Testing does not ensure that remaining defects are documented, but rather that detected defects are reported. Testing does not remove errors in software, but rather finds defects in software behavior or quality. Testing does not eliminate the risk with software, but rather assesses and manages the risk with software.

NEW QUESTION # 47
The following part of a business process flow is specified; REPEAT (book a bill) UNTIL (User presses Cancel). How many test cases are necessary in order to achieve 100% branch coverage of the process flow?
- A. 0
- B. 1
- C. 2
- D. Infinite
Answer: C
Explanation:
To achieve 100% branch coverage of the process flow, we need to test both the true and false outcomes of the condition (User presses Cancel). Branch coverage is a type of structural testing that measures how many decision outcomes in a program have been executed by a test suite. Branch coverage can be used to assess the adequacy or completeness of a test suite.
To test the true outcome of the condition, we need a test case that simulates the user pressing Cancel after booking a bill. This test case will exit the loop and end the process flow.
To test the false outcome of the condition, we need a test case that simulates the user not pressing Cancel after booking a bill. This test case will repeat the loop and book another bill.
Therefore, we need at least two test cases to achieve 100% branch coverage of the process flow. One test case for each possible outcome of the condition.

NEW QUESTION # 48
The following incident report that was generated during test of a web application.
What would you suggest as the most important report improvement?
Defect detected date: 15 8.2010
Defect detected by: Joe Smith
Test level System test
Test case: Area 5/TC 98
Build version: 2011-16.2
Defect description After having filled out all required fields in screen 1, t click ENTER to continue to screen 2 Nothing happens, no system response at all.
- A. Add information about which developer should fix the bug
- B. Add information about which web browser was used
- C. Add an impact analysis
- D. Add the time stamp when the incident happened
Answer: B
Explanation:
The most important report improvement for the given incident report would be to add information about which web browser was used when the defect was detected. This information is relevant for reproducing and debugging the defect, as different web browsers may have different behaviors or compatibility issues with the web application. The other options are less important or irrelevant for the incident report. The developer who should fix the bug can be assigned by the project manager or the defect tracking system, not by the tester who reports the defect. The time stamp when the incident happened is not very useful, as it does not indicate the cause or the frequency of the defect. The impact analysis is not part of the incident report, but rather of the risk assessment or prioritization process.

NEW QUESTION # 49
Which test approach will best fit a new project, with little documentation and high probability for bugs?
- A. Requirements based testing
- B. Exploratory testing
- C. Metric based approach
- D. Regression testing
Answer: B
Explanation:
Exploratory testing is an approach to testing that emphasizes learning, test design and test execution at the same time. Exploratory testing relies on the tester's skills, creativity and intuition to explore the software under test and discover defects. Exploratory testing is suitable for a new project with little documentation and high probability for bugs, as it can help uncover unknown requirements, assumptions and risks. Exploratory testing is not requirements based testing, which is an approach to testing that derives test cases from documented requirements or specifications. Requirements based testing is not feasible for a new project with little documentation, as it requires clear and complete requirements to be available. Exploratory testing is not metric based approach, which is an approach to testing that uses quantitative measures to monitor and control the testing process and evaluate the quality of the software product. Metric based approach is not effective for a new project with high probability for bugs, as it may not capture all aspects of quality and may lead to false confidence or unrealistic expectations. Exploratory testing is not regression testing, which is an approach to testing that verifies that previously tested software still performs correctly after changes. Regression testing is not relevant for a new project with no previous versions or baselines.

NEW QUESTION # 50
A mid-size software product development company has analyzed data related to defects detected in its product and found out that detects fixed in earlier builds are getting re-opened after a few months.
The company management now seeks your advice in order to reverse this trend and prevent re-opening of defects fixed earlier.
What would be your FIRST recommendation to the company?
- A. Verify existing regression test suite are adequate, and augment it, if required, in order to ensure that defects fixed earlier get re-tested in each subsequent build
- B. If required, tram the teams responsible for development and testing of the modules containing maximum number of defects, and if this does not help, replace them with more knowledgeable people
- C. Automate existing test suits so that lesser time is spent on execution of each test, and more tests can be executed m the available time thus leading to a lower probability of defects slipping by
- D. Analyze the product modules containing maximum defects, and get them thoroughly tested and defects fixed as a one-time activity
Answer: A
Explanation:
Regression testing is a type of testing that verifies that previously tested software still performs correctly after changes. Regression testing can help prevent re-opening of defects fixed earlier by ensuring that they do not cause any new failures or side effects. The first recommendation to the company is to verify existing regression test suite are adequate, and augment it, if required, in order to ensure that defects fixed earlier get re-tested in each subsequent build. This can help improve the coverage and effectiveness of regression testing and detect any regression defects as soon as possible. Automating existing test suites may also help reduce the time and effort required for regression testing, but this is not the first recommendation, as automation may not be feasible or cost-effective for all test cases. Analyzing the product modules containing maximum defects and getting them thoroughly tested and defects fixed as a one-time activity may also help reduce the defect density and improve the quality of those modules, but this is not the first recommendation, as it does not address the root cause of re-opening defects fixed earlier. Training or replacing the teams responsible for development and testing of the modules containing maximum number of defects may also help improve their skills or performance, but this is not the first recommendation, as it may not be necessary or appropriate for all teams.

I Generally, decision tables are generated for low risk test items.
II Test cases derived from decision tables can be used for component tests.
III Several test cases can be selected for each column of the decision table.
IV The conditions in the decision table represent negative tests generally.
- A. I. Ill
- B. I. IV
- C. II. Ill
- D. Generally, decision tables are generated for low risk test items. Decision tables are not related to risk level, but rather to complexity level. Decision tables are generated for test items that have complex logic or multiple conditions and actions that need to be tested.
- E. II. IV
Answer: C
Explanation:
IV. The conditions in the decision table represent negative tests generally. The conditions in the decision table represent both positive and negative tests, depending on whether they are valid or invalid inputs for the test item. Verified Reference: A Study Guide to the ISTQB Foundation Level 2018 Syllabus - Springer, Chapter 4, page 42-43.
Explanation:
A decision table is a technique that shows combinations of inputs and/or stimuli (causes) with their associated outputs and/or actions (effects). A decision table consists of four quadrants: conditions (inputs), actions (outputs), condition entries (values) and action entries (results). The following statements about decision tables are true:
II. Test cases derived from decision tables can be used for component tests. Decision tables can be used to test components that have multiple inputs and outputs that depend on logical combinations of conditions. Decision tables can help cover all possible combinations or scenarios in a systematic way.
III. Several test cases can be selected for each column of the decision table. A column of a decision table represents a unique combination of condition entries and action entries. Several test cases can be selected for each column by varying other input values or expected results that are not part of the decision table. The following statements about decision tables are false:

Which of the following is an example of black-box dynamic testing?
- A. Checking memory leaks for a program by executing it
- B. Code inspection
- C. Coverage analysis
- D. Functional Testing
Answer: D
Explanation:
Functional testing is an example of black-box dynamic testing. Black-box testing (also known as specification-based testing) is a type of testing that does not consider the internal structure or implementation of the system under test, but rather its external behavior or functionality. Dynamic testing is a type of testing that involves executing the system under test with various inputs and observing its outputs. Functional testing is a type of black-box dynamic testing that verifies that the system under test performs its intended functions according to its requirements or specifications. Functional testing can be performed at various levels and scopes depending on the objectives and criteria of testing. The other options are not examples of black-box dynamic testing. Code inspection is an example of white-box static testing. White-box testing (also known as structure-based testing) is a type of testing that considers the internal structure or implementation of the system under test. Static testing is a type of testing that does not involve executing the system under test, but rather analyzing it for defects, errors, or violations of standards. Code inspection is a type of white-box static testing that involves examining the source code of the system under test for quality, readability, maintainability, etc. Checking memory leaks for a program by executing it is an example of white-box dynamic testing. Memory leaks are defects that occur when a program fails to release memory that it has allocated but no longer needs. Checking memory leaks for a program by executing it requires knowledge and access to the internal structure or implementation of the program, such as memory allocation and deallocation mechanisms, pointers, references, etc. Coverage analysis is an example of white-box static testing. Coverage analysis is a technique that measures how much of the code or structure of the system under test has been exercised by a test suite. Coverage analysis requires knowledge and access to the internal structure or implementation of the system under test, such as statements, branches, paths, conditions, etc. Verified Reference: A Study Guide to the ISTQB Foundation Level 2018 Syllabus - Springer, page 7.
NEW QUESTION # 53
Which of the following should be included in a test status report?
I Estimation details
II Total number of open and closed defects
III Actual effort spent
IV Defect reports
V Number of executed, failed, blocked tests
- A. III.V
- B. II, III.V
- C. I. II. IV
- D. II, III
Answer: B
Explanation:
The following should be included in a test status report: total number of open and closed defects, actual effort spent, and number of executed, failed, and blocked tests. A test status report is a document that provides information on the results and status of testing activities for a given period or phase. A test status report should include information that is relevant, accurate, and timely for the intended audience and purpose. Some of the information that should be included in a test status report are: total number of open and closed defects, which can indicate the defect trend and defect density of the software product; actual effort spent, which can indicate the productivity and efficiency of the testing process; number of executed, failed, and blocked tests, which can indicate the test progress and test coverage of the software product. The following should not be included in a test status report: estimation details, defect reports, and impact analysis. Estimation details are not part of a test status report, but rather part of a test plan or a test estimation document. Estimation details provide information on the expected time, resources, and costs for testing activities, not on the actual results or status of testing activities. Defect reports are not part of a test status report, but rather separate documents that provide detailed information on individual defects found during testing. Defect reports include information such as defect description, defect severity, defect priority, defect status, defect resolution, etc. Defect reports can be referenced or summarized in a test status report, but not included in full. Impact analysis is not part of a test status report, but rather part of a risk assessment or prioritization process. Impact analysis provides information on the potential effects or consequences of a change or a defect on the software product or project. Impact analysis can be used to evaluate the amount or scope of testing to be performed, but not to report the results or status of testing activities.

NEW QUESTION # 54
Which of the following is NOT a deciding factor m determining the extent of testing required?
- A. A particular tester involved in testing
- B. Budget to do testing
- C. Time available to do testing
- D. Level of risk of the product or features
Answer: A
Explanation:
The extent of testing required for a software product depends on various factors, such as the level of risk, the budget, and the time available. The level of risk reflects the potential impact of failures on the stakeholders and the environment. The budget determines how much resources can be allocated for testing. The time available defines the schedule and deadlines for testing activities. The particular tester involved in testing is not a deciding factor for the extent of testing required, as testing should be based on objective criteria and not on personal preferences or abilities.

NEW QUESTION # 55
Which of the following statements contradicts the general principles of testing?
- A. If new defects are to be found we should run the same test set more often.
- B. How testing is done, is based on the situation in a particular project.
- C. Testing is better if it starts at the beginning of a project.
- D. Most defects are found in a small subset of a system's modules.
Answer: A
Explanation:
Statement B contradicts the general principles of testing, because running the same test set more often will not increase the chances of finding new defects, unless there are some changes in the system or environment that affect the test results. Running different test sets with different inputs, outputs or conditions would be more effective in finding new defects. Statements A, C and D are consistent with the general principles of testing. Statement A states that most defects are found in a small subset of a system's modules, which is true according to the defect clustering principle. Statement C states that testing is better if it starts at the beginning of a project, which is true according to the early testing principle. Statement D states that how testing is done, is based on the situation in a particular project, which is true according to the context-dependent testing principle.
