- 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.

NEW QUESTION # 18
Consider the following user story about the authentication functionality of an e-commerce website:
"As a logged-in user, I want to change my current password with a new one, so that I can make my account safer".
The following are some of the acceptance criteria defined for the user story:
[a] After the logged-in user has successfully changed his password, an email confirming the change must be sent to him
[b] To successfully change the password, the logged-in user must enter the current password, enter a new valid password, and finally confirm by pressing the 'Change Password' button
[c] To be valid, the new password entered by the logged-in user is not only required to meet the criteria related to the length and type of characters, but must also be different form the last 5 passwords of that user
[d] A dedicated error message must be presented to the logged-in user when he enters a wrong current password
[e] A dedicated error message must be presented to the logged-in user when he enters the correct current password, but enters an invalid password Based only on the given information, which of the following ATDD tests is most likely to be written first?
- A. The logged-in user submits a purchase order containing ten items, selects to pay with a Visa credit card, enters credit card information of a valid card, presses the 'Confirm' button, and finally views the dedicated message confirming that the purchase has been successful
- B. The logged-in user enters the correct current password, enters an invalid password, and finally views the dedicated error
- C. The logged-in user enters a wrong current password and views the dedicated error message
- D. The logged-in user enters the correct current password, enters a valid new password (different from the last 5 passwords), presses the Change Password' button, and finally receives the e-mail confirming that the password has been successfully changed
Answer: D
Explanation:
ATDD stands for Acceptance Test-Driven Development, which is a collaborative approach to software development and testing, in which the acceptance criteria of a user story are defined and automated as executable tests before the implementation of the software system. ATDD tests are usually written in a Given-When-Then format, which describes the preconditions, the actions, and the expected outcomes of a test scenario. ATDD tests are intended to verify that the software system meets the expectations and the needs of the users and the stakeholders, as well as to provide feedback and guidance for the developers and the testers. Based on the given information, the ATDD test that is most likely to be written first is the one that corresponds to option B, which is:
Given the logged-in user is on the Change Password page When the user enters the correct current password, enters a valid new password (different from the last 5 passwords), and presses the Change Password button Then the user receives an email confirming that the password has been successfully changed This ATDD test is most likely to be written first, because it covers the main functionality and the happy path of the user story, as well as the most important acceptance criterion [a]. It also verifies that the user can change the password with a valid new password that meets the criteria related to the length, the type of characters, and the history of the passwords, as specified in the acceptance criterion [c]. The other options are not likely to be written first, because they either cover less critical or less frequent scenarios, such as entering a wrong current password [d] or an invalid new password [e], or they are not related to the user story or the acceptance criteria at all, such as submitting a purchase order [d].

NEW QUESTION # 19
Which of the following is not an example of a typical generic skill required for testing?
- A. Be able to apply test-driven development
- B. Be able to use test management tools and defect tracking tools
- C. Be able to communicate defects and failures to developers as objectively as possible
- D. Possess the necessary social skills that support effective teamwork
Answer: A
Explanation:
Test-driven development is not an example of a typical generic skill required for testing, but rather an example of a specific technical skill or a development practice that may or may not be relevant for testing, depending on the context and the objectives of the testing activities. Test-driven development is an approach to software development and testing, in which the developers write automated unit tests before writing the source code, and then refactor the code until the tests pass. Test-driven development can help to improve the quality, the design, and the maintainability of the code, as well as to provide fast feedback and guidance for the developers. However, test-driven development is not a skill that is generally expected or needed for testers, especially for testers who are not involved in unit testing or who do not have access to the source code. The other options are examples of typical generic skills required for testing, which are skills that are applicable and beneficial for testing in any context or situation, regardless of the specific testing techniques, tools, or methods used. The typical generic skills required for testing include:
Be able to use test management tools and defect tracking tools: These are tools that help testers to plan, organize, monitor, and control the testing activities and resources, as well as to record, track, analyze, and resolve the defects detected during testing. These tools can improve the efficiency, the effectiveness, and the communication of the testing process, as well as to provide traceability, metrics, and reports for the testing outcomes.
Be able to communicate defects and failures to developers as objectively as possible: This is a skill that involves the ability to report and describe the defects and failures found during testing in a clear, concise, accurate, and unbiased manner, using relevant information, evidence, and terminology, without making assumptions, judgments, or accusations. This skill can facilitate the collaboration, the understanding, and the resolution of the defects and failures between the testers and the developers, as well as to prevent conflicts, misunderstandings, or blame games.
Possess the necessary social skills that support effective teamwork: These are skills that involve the ability to interact, cooperate, and coordinate with other people involved in or affected by the testing activities, such as the test manager, the test team, the project manager, the developers, the customers, the users, etc. These skills can include communication, negotiation, leadership, motivation, feedback, conflict resolution, etc. These skills can enhance the quality, the productivity, and the satisfaction of the testing process, as well as to foster a positive and constructive testing culture.

- A. Product risk refers to the risk associated with the project's schedule, budget, and resources, while project risk refers to the risk associated with the quality and functionality of the software product.
- B. Product risk refers to the risk associated with delays in elements such as work product deliveries and inaccurate estimates, while project risk refers to the risk associated with issues such as user dissatisfaction.
- C. Product risk refers to the risk associated with issues such as delays in work product deliveries, inaccurate estimates, while project risk refers to the risk associated with the project's schedule, budget, and resources.
- D. Product risk and project risk are essentially the same and can be used interchangeably.
Answer: C
Explanation:
Product risk involves the potential issues that can affect the quality and functionality of the software product, such as defects, performance problems, and usability issues. Project risk, on the other hand, relates to the risks that can impact the project's schedule, budget, and resources, such as delays, cost overruns, and resource constraints. Understanding both types of risks is crucial for managing and mitigating potential problems in software projects.
NEW QUESTION # 23
The following 4 equivalence classes are given:
Which of the following alternatives includes correct test values for x. based on equivalence partitioning?
- A. -99; 99:101; 1001
- B. -500; 0; 100; 1000
- C. -1000; -100; 100; 1000
- D. -100; 100:1000; 1001
Answer: C
Explanation:
The question is about selecting the correct test values for x based on equivalence partitioning. Equivalence partitioning is a software test design technique that divides the input data of a software unit into partitions of equivalent data from which test cases can be derived. In this case, the given equivalence classes are:
(x \leq -100)
(-100 < x < 100)
(100 \leq x < 1000)
(x \geq 1000)
Option D provides a value from each of these partitions:
For (x \leq -100), it gives -1000.
For (-100 < x < 100), it gives -100 and 100.
For (100 \leq x < 1000), it gives 500.
For (x \geq 1000), it gives 1500.
So, option D covers all four given equivalence classes with appropriate values.

NEW QUESTION # 24
Who of the following has the best knowledge to decide what tests in a test project should be automated?
- A. The development manager
- B. The test leader
- C. The customer
- D. The developer
Answer: B
Explanation:
The test leader is the person who is responsible for planning, monitoring, and controlling the test activities and resources in a test project. The test leader should have the best knowledge of the test objectives, scope, risks, resources, schedule, and quality criteria. The test leader should also be aware of the test automation criteria, such as the execution frequency, the test support, the team education, the roles and responsibilities, and the devs and testers collaboration1. Based on these factors, the test leader can decide which tests are suitable for automation and which are not, and prioritize them accordingly. The test leader can also coordinate with the test automation engineers, the developers, and the stakeholders to ensure the alignment of the test automation strategy with the test project goals and expectations.

NEW QUESTION # 25
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: A
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 # 26
Which one of the following statements IS NOT a valid objective of testing?
- A. To find failures and defects
- B. To build confidence in the level of quality of the test object.
- C. To find all defects in a product, ensuring the product is defect free.
- D. To evaluate work products such as requirements, user stories, design, and code.
Answer: C
Explanation:
Finding all defects in a product and ensuring it is defect-free is not a valid objective of testing. Testing aims to find as many defects as possible, build confidence in the quality of the product, and evaluate work products. However, it is unrealistic to expect testing to find all defects, and declaring a product completely defect-free is impractical.
Reference: ISTQB CTFL Syllabus V4.0, Section 1.1.1
NEW QUESTION # 27
A financial institution is to implement a system that calculates the interest rates paid on investment accounts based on the sum invested.
You are responsible for testing the system and decide to use equivalence partitioning and boundary value analysis to design test cases. The requirements describe the following expectations:
Investment range | Interest rate
R500 to RIO 000 10%
RIO 001 to R50 000 11%
R50 001 to RlOOOOO 12%
RIOOOOl to R500 000 | 13%
What is the minimum number of test cases required to cover all valid equivalence partitions for calculating the interest?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: A
Explanation:
Using equivalence partitioning, the investment ranges are divided into four partitions:
R500 to R10,000 (10%)
R10,001 to R50,000 (11%)
R50,001 to R100,000 (12%)
R100,001 to R500,000 (13%)
Thus, the minimum number of test cases required to cover all valid equivalence partitions for calculating the interest is 4.
