NEW QUESTION # 23
The following requirement is given "Set X to be the sum of Y and Z".
All the following four implementations have bugs.
Which one of the following bugs can be caught by Static Analysis?
- A. int x = 1.
Int y = 2.
Int z = 3.
Z = x +y - B. int y = 2
Int z = 3.
Y = z+y - C. int x = 1.
int y = 2.
int y = 3.
X = y=z; - D. int x = 1.
int y = 2.
int z = 3.
X = z-y
Answer: C
Explanation:
Static analysis is a technique that analyzes the source code or other software artifacts without executing them. Static analysis can detect defects such as syntax errors, coding standards violations, potential security vulnerabilities, or logical flaws. Static analysis can catch the bug in the first implementation, as it contains two syntax errors: the variable y is declared twice, and the assignment statement X = y=z is invalid. Static analysis cannot catch the bugs in the other three implementations, as they are logical errors that do not violate any syntax rules, but produce incorrect results.

NEW QUESTION # 24
Which of the following is NOT a product risk?
- A. Software does not perform the intended functions
- B. Problems in defining the right requirements
- C. Failure-prone software is delivered
- D. Poor software usability
Answer: B
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.

Which of the following is the most important task of a typical test leader?
- A. To coordinate the test strategy with project managers.
- B. To set up the test environment.
- C. To prepare and acquire test data.
- D. To automate tests.
Answer: A
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 # 27
Which type of software development product can undergo static testing?
- A. Any software development product can undergo static testing, including requirements specifications, design specifications and code.
- B. Static tests should be performed on the installation and user guide documents as these documents are used by the end user.
- C. Static testing is done only on the requirements You need to execute the software in order to find defects in the code.
- D. Static testing is done only on the code as part of the "code review" sessions Other documents are reviewed, but not by static testing.
Answer: A
Explanation:
Static testing is a form of testing that does not involve executing the software, but rather analyzing it for defects, errors, or violations of standards. Static testing can be applied to any software development product, including requirements specifications, design specifications, code, test cases, test plans, user manuals, etc. Static testing can be done by using various techniques such as reviews, inspections, walkthroughs, checklists, static analysis tools, etc. Verified Reference: A Study Guide to the ISTQB Foundation Level 2018 Syllabus - Springer, page 7.
NEW QUESTION # 28
Which of the following statements contradicts the general principles of testing?
- A. Most defects are found in a small subset of a system's modules.
- 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. If new defects are to be found we should run the same test set more often.
Answer: D
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.

Explanation:
The relationship between impact analysis and regression testing in maintenance testing is that impact analysis is used to evaluate the amount of regression testing to be performed. Maintenance testing is a type of testing that is performed on an existing software product after it has been delivered or deployed, in order to ensure that it still meets its requirements and functions correctly after a change or a modification. Maintenance testing can be triggered by various reasons, such as corrective maintenance (fixing defects), adaptive maintenance (adapting to new environments), perfective maintenance (improving performance), preventive maintenance (avoiding future problems), etc. Impact analysis is a technique that is used to assess the extent and nature of changes introduced by maintenance activities on the software product or project. Impact analysis helps to identify which parts of the software product are affected by the changes, which parts need to be modified or updated accordingly, which parts need to be retested or verified for correctness or compatibility, etc. Regression testing is a type of testing that verifies that previously tested software still performs correctly after a change or a modification. Regression testing helps to detect any side effects or unintended consequences of maintenance activities on the software product's functionality or quality. Regression testing can be performed at various levels and scopes depending on the impact analysis results. Therefore, in maintenance testing, impact analysis is used to evaluate the amount of regression testing to be performed.

NEW QUESTION # 31
Which of the following is correct with regards to debugging?
- A. Debugging is often performed by test engineers
- B. Debugging identifies the cause of a failure
- C. Debugging is considered part of the testing activities
- D. Debugging is intended to find as many defects as possible in the code
Answer: B
Explanation:
Debugging is the process of finding, analyzing and removing the causes of failures in software. Debugging is not considered part of testing, but rather a development activity that can involve testing. Debugging is not intended to find as many defects as possible, but rather to fix the specific failure that was observed. Debugging is usually performed by developers, not by test engineers.

NEW QUESTION # 32
You need to test the login page of a web site. The page contains fields for user name and password. Which test design techniques are most appropriate for this case?
- A. Decision table testing, state transition testing.
- B. Equivalence partitioning, Boundary value analysis.
- C. Exploratory testing, statement coverage.
- D. Decision coverage, fault attack.
Answer: B
Explanation:
Equivalence partitioning and boundary value analysis are test design techniques that are most appropriate for testing the login page of a web site. The page contains fields for user name and password, which are input values that can be divided into partitions of equivalent data. Equivalence partitioning is a technique that divides the input data and output results of a software component into partitions of equivalent data. Each partition should contain data that is treated in the same way by the component. Equivalence partitioning can be used to reduce the number of test cases by selecting one representative value from each partition. Boundary value analysis is a technique that tests boundary values between partitions of equivalent data. Boundary values are values at the edge of an equivalence partition or at the smallest incremental distance on either side of an edge. Boundary value analysis can be used to detect defects caused by incorrect handling of boundary conditions. For example, for testing the user name field, we can identify two equivalence partitions: valid user name (existing and correct) and invalid user name (non-existing or incorrect). The boundary values for these partitions are the minimum and maximum length of user name allowed by the system.
Decision table testing and state transition testing are not suitable for testing the login page of a web site, as they are more applicable for testing components that have multiple inputs and outputs that depend on logical combinations of conditions or events. Decision table testing is a technique that shows combinations of inputs and/or stimuli (causes) with their associated outputs and/or actions (effects). State transition testing is a technique that models how a system transitions from one state to another depending on events or conditions.
Exploratory testing and statement coverage are not suitable for testing the login page of a web site, as they are more applicable for testing components that require learning, creativity and intuition or structural analysis. 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. Statement coverage is a type of structural testing that measures how many statements in a program have been executed by a test suite. Statement coverage can be used to assess the adequacy or completeness of a test suite.
Decision coverage and fault attack are not suitable for testing the login page of a web site, as they are more applicable for testing components that have complex logic or potential errors. Decision coverage is a type of structural testing that measures how many decision outcomes in a program have been executed by a test suite. Decision coverage can be used to assess the adequacy or completeness of a test suite. Fault attack is a type of functional testing that deliberately introduces faults into a system in order to provoke failures or errors.

NEW QUESTION # 33
A system computes prices for bus tickets. The price depends on
- the passenger type (baby, child, adult, senior citizen, student, military)
- the travelling type (as single or in a group)
- the distance (zone 1. 2. 3)
- the kind of transport (ordinary, express)
Which of the following test techniques is the most appropriate one for testing the price computation?
- A. Equivalence partitioning
- B. State transition testing
- C. Use case testing
- D. Statement coverage
Answer: A
Explanation:
Equivalence partitioning is a technique that divides the input data and output results of a software component into partitions of equivalent data. Each partition should contain data that is treated in the same way by the component. Equivalence partitioning can be used to reduce the number of test cases by selecting one representative value from each partition. Equivalence partitioning is suitable for testing the price computation, as it can identify different partitions based on the passenger type, the travelling type, the distance and the kind of transport. Equivalence partitioning is not statement coverage, which is a technique that measures how many executable statements in a source code are executed by a test suite. Statement coverage is not appropriate for testing the price computation, as it does not consider the input data or output results. Equivalence partitioning is not state transition testing, which is a technique that models how a system transitions from one state to another depending on events or conditions. State transition testing is not relevant for testing the price computation, as it does not involve any states or transitions. Equivalence partitioning is not use case testing, which is a technique that tests how users interact with a system to achieve a specific goal. Use case testing is not applicable for testing the price computation, as it does not focus on a single function or component.

NEW QUESTION # 34
Which of the following is true about Oracles?
- A. Oracles help in reproducing the irreproducible bugs
- B. Oracles can be generated automatically using data generators
- C. Sometimes old version of a product can be used as an Oracle
- D. Oracles are derived from the design
Answer: C
Explanation:
An oracle is a mechanism or source that can provide the expected result for a given test input or situation. Sometimes old version of a product can be used as an oracle, if it is assumed that the old version behaves correctly for the test cases that are executed on the new version. This is also known as back-to-back testing. Oracles do not help in reproducing the irreproducible bugs, as they only provide the expected results, not the actual results. Oracles are not derived from the design, but from the requirements or specifications. Oracles cannot be generated automatically using data generators, as data generators only provide test inputs, not test outputs.

NEW QUESTION # 35
Which of the following statements about testware are correct?
I When closing the test activities, all the testware resources can be uninstalled and released II All the testware should be subject to Configuration Management III. The testware. at the end of the project, should be transferred to the organization responsible for maintenance IV The developers are responsible for the correct installation of the testware
- A. I, Ill
- B. I, IV
- C. II, Ill
- D. II, IV
Answer: C
Explanation:
Testware is a term that refers to all artifacts produced during the testing process, such as test plans, test cases, test scripts, test data, test results, defect reports, etc. The following statements about testware are correct:
II) All the testware should be subject to Configuration Management. Configuration management is a process that establishes and maintains consistency among work products throughout their life cycle. Configuration management applies to all testware, as it helps ensure their quality and consistency, track their changes and defects, control their versions and access rights, and link them to other artifacts.
III) The testware at the end of the project should be transferred to the organization responsible for maintenance. Maintenance testing is testing performed on a software product after delivery to correct defects or improve performance or other attributes. Maintenance testing requires testware from previous testing activities or phases, such as test cases, test data, test results, etc. Therefore, the testware at the end of the project should be transferred to the organization responsible for maintenance testing, such as support team or maintenance team. The following statements about testware are incorrect:
I) When closing the test activities, all the testware resources can be uninstalled and released. This statement is incorrect, as some testware resources may still be needed for future testing activities or phases, such as maintenance testing or regression testing. Therefore, when closing the test activities, some testware resources should be archived and stored for future use, while others can be uninstalled and released.
IV) The developers are responsible for the correct installation of the testware. This statement is incorrect, as the testers are responsible for the correct installation of the testware. The testers should ensure that they have access to all necessary testware resources and that they are installed and configured properly before starting the test execution.

NEW QUESTION # 36
Which of the following statements about independent testing is WRONG?
- A. Independent testing is best suited for the system test level.
- 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 necessary because developers don't know any testing.
Answer: D
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 # 37
Which of the following statements about re-testing and regression testing are TRUE?
I Re-testing should be performed after a defect is fixed.
II Regression testing should always be performed after a defect is fixed.
III Re-testing and regression testing may be performed at any test level.
IV Regression testing may include functional, non-functional and structural testing.
V Re-testing should be included in the debugging activity.
- A. I, III. Iv
- B. I, Ill
- C. II. IV, V
- D. II, v
Answer: A
Explanation:
The following statements about re-testing and regression testing are true:
I) Re-testing should be performed after a defect is fixed. Re-testing is a type of testing that verifies that a defect has been successfully resolved by executing a test case that previously failed due to that defect. Re-testing should be performed after a defect is fixed and delivered to ensure that it does not cause any new failures or side effects.
III) Re-testing and regression testing may be performed at any test level. Re-testing and regression testing are not limited to a specific test level, but can be applied at any level depending on the context and objectives. For example, re-testing and regression testing can be performed at unit level, integration level, system level or acceptance level.
IV) Regression testing may include functional, non-functional and structural testing. Regression testing is a type of testing that verifies that previously tested software still performs correctly after changes. Regression testing may include various types of testing depending on the scope and purpose of the changes. For example, regression testing may include functional testing to check if the software meets its requirements, non-functional testing to check if the software meets its quality attributes, or structural testing to check if the software meets its design or code standards. The following statement about re-testing and regression testing is false:
II) Regression testing should always be performed after a defect is fixed. Regression testing is not always necessary after a defect is fixed, as some defects may have a low impact or low likelihood of affecting other parts of the software. Regression testing should be performed after a defect is fixed only if there is a risk of introducing new defects or causing existing defects due to the changes made to fix the defect.

NEW QUESTION # 38
Which of the following does MOT describe a reason why testing is necessary?
- A. The acquisition of test automation tools was based on the assumption that it will be used m all projects
- B. The risks associated with delivering the system are far higher than the cost of testing
- C. For avionics and pharmaceutical systems software testing is mandated by standards
- D. The customer decided that 100% branch coverage shall be achieved
Answer: A
Explanation:
Testing is necessary for various reasons, such as:
To detect defects and failures that may affect the quality, performance, reliability or security of a software product or system To verify that a software product or system meets its specified requirements, expectations and standards To validate that a software product or system fulfills its intended purpose and satisfies its stakeholders' needs To provide information and feedback about the status and risks of a software product or system To comply with regulations or contractual obligations that mandate testing for certain types of software products or systems The following statements describe some reasons why testing is necessary:
A) The customer decided that 100% branch coverage shall be achieved. This is a reason why testing is necessary, as it reflects a contractual obligation or a quality standard that requires testing to measure and achieve a certain level of code coverage.
C) For avionics and pharmaceutical systems software testing is mandated by standards. This is a reason why testing is necessary, as it reflects a regulation or a compliance requirement that mandates testing for certain types of software products or systems that have high safety or security risks.
D) The risks associated with delivering the system are far higher than the cost of testing. This is a reason why testing is necessary, as it reflects a risk-based approach that considers testing as an investment to reduce the probability and impact of potential failures or defects. The following statement does not describe a reason why testing is necessary:
B) The acquisition of test automation tools was based on the assumption that it will be used m all projects. This is not a reason why testing is necessary, as it reflects a business decision or a resource allocation that does not justify the need or purpose of testing. Test automation tools are not always suitable or beneficial for all projects, and testing can be performed with or without test automation tools.

NEW QUESTION # 39
Which of the following is a key characteristic of informal reviews?
- A. Low cost
- B. Kick-off meeting
- C. Individual preparation
- D. Metrics analysis
Answer: A
Explanation:
A key characteristic of informal reviews is low cost. Informal reviews are a type of review that does not follow a formal process or have any formal documentation. Informal reviews are usually performed by individuals or small groups of peers or colleagues who have some knowledge or interest in the product under review. Informal reviews can be done at any time and for any purpose, such as checking for errors, clarifying doubts, sharing ideas, etc. Informal reviews have low cost, as they do not require much time, effort, or resources to conduct. The other options are not key characteristics of informal reviews. Kick-off meeting is a characteristic of formal reviews, such as inspections or walkthroughs. Kick-off meeting is a meeting that is held before the review process starts, where the roles and responsibilities of the participants are defined, the objectives and scope of the review are agreed, and the logistics and schedule of the review are planned. Individual preparation is a characteristic of formal reviews, such as inspections or walkthroughs. Individual preparation is an activity that is performed by the reviewers before the review meeting, where they examine the product under review and identify any issues or questions that need to be discussed or resolved during the review meeting. Metrics analysis is a characteristic of formal reviews, such as inspections or walkthroughs. Metrics analysis is an activity that is performed after the review process is completed, where the data and results of the review are collected and analyzed to measure the effectiveness and efficiency of the review, as well as to identify any improvement actions or lessons learned for future reviews.

- A. monitoring tool
- B. configuration management tool
- C. test design tool
- D. unit test framework tool
Answer: D
Explanation:
A unit test framework tool is a tool that supports the creation, execution, and reporting of unit tests, which are tests that verify the functionality and quality of individual software components (such as functions or methods) in source code. A unit test framework tool can help to detect defects in functions or methods in source code by providing features such as test case generation, test case execution, test result comparison, test coverage measurement, etc. Some examples of unit test framework tools are JUnit, NUnit, TestNG, etc. The other options are not tools that are likely to detect defects in functions or methods in source code. A configuration management tool is a tool that supports the management and control of different versions and variants of software products or components. A test design tool is a tool that supports the design and generation of test cases based on some criteria or rules.

NEW QUESTION # 41
Which of the following is a correct reason to apply test automation?
- A. When it is easy to automate
- B. When a new test automation tool is launched
- C. When there are a lot of repetitive testing tasks
- D. When it is cheap to buy test automation tools
Answer: C
Explanation:
A correct reason to apply test automation is when there are a lot of repetitive testing tasks. Test automation is the use of software tools or scripts to perform or support testing activities, such as test case execution, test result comparison, test data generation, etc. Test automation can be beneficial when there are a lot of repetitive testing tasks that need to be performed frequently or consistently, such as regression testing, performance testing, load testing, etc. Test automation can help to save time and effort, increase reliability and accuracy, and improve coverage and efficiency of testing. The other options are not correct reasons to apply test automation. When a new test automation tool is launched is not a reason to apply test automation, but rather a factor for choosing a test automation tool. When it is easy to automate is not a reason to apply test automation, but rather a factor for evaluating the feasibility of test automation. When it is cheap to buy test automation tools is not a reason to apply test automation, but rather a factor for estimating the cost and benefit of test automation.

NEW QUESTION # 42
Which of the following statements is LEAST likely to be describing component testing?
- A. It identifies defects in modules and classes.
- B. Simulators and stubs may be required.
- C. It may be applied using a test-first approach.
- D. It mainly tests interfaces and interaction between components.
Answer: D
Explanation:
Component testing (also known as unit testing or module testing) is a level of testing that focuses on verifying the functionality and quality of individual software components (such as modules, classes, functions, methods, etc.). Component testing mainly tests interfaces and interaction between components, as well as internal logic and data structures of the components. Component testing may be applied using a test-first approach (such as test-driven development or behavior-driven development), where tests are written before the code is implemented. Component testing does not identify defects in modules and classes, as this is a result of component testing, not an objective. Simulators and stubs may be required for component testing, as they can simulate or replace missing or incomplete components or external systems that are needed for testing.
