NEW QUESTION # 21
Which of the following is a key activity in a usability test session?
- A. Extract usability findings and recommendations
- B. Test the set up and modify the test script if needed
- C. Talk to the participant during the completion of a task
- D. Moderate the usability test
Answer: D
Explanation:
Moderating the usability test is a core activity during the actual usability test session. The moderator guides participants through tasks, ensures the session stays on track, and avoids introducing bias. Option A (testing the setup) happens before the session, during preparation. Option C (extracting findings) occurs during analysis, after the test. Option D (talking during task execution) should be minimized unless necessary, to avoid influencing user behavior. Therefore, option B is the only correct answer aligned with best practices in usability testing.

NEW QUESTION # 22
Why are positive usability findings of high importance? Which of the following statements is wrong?
- A. Positive usability findings should be used to communicate to the development team which features should not be modified or deleted.
- B. Positive findings are of high importance because they can be used in the report to justify the costs of the test.
- C. Positive usability findings make it easier to sell the need for correcting usability problems by giving a balanced view.
- D. Positive usability findings allow a better view of the usability of the product.
Answer: B
Explanation:
Positive usability findings play a key role in reinforcing what is working well in the user interface. They help:
A: Build developer confidence and soften criticism when pointing out issues.
C: Provide a complete picture of usability strengths and weaknesses.
D: Inform developers what should remain unchanged during redesign.
However, B is incorrect because justifying usability test costs should not rely solely on positive findings. Cost justification should come from the overall impact of usability on user satisfaction, performance, and business outcomes-not just good results.

NEW QUESTION # 23
What is the System Usability Scale (SUS)?
- A. A usability test execution activity specified by the moderator that needs to be accomplished by a usability test participant within a given period of time.
- B. Testing to evaluate the degree to which the system can be used by specified users with effectiveness, efficiency and satisfaction in a specified context of use.
- C. A simple, ten-item attitude scale giving a global view of subjective assessments of usability.
- D. A requirement on the usability of a component of system
Answer: C
Explanation:
The System Usability Scale (SUS) is a standardized, reliable tool used to measure perceived usability. It consists of 10 items with five response options (from strongly agree to strongly disagree). It is widely used due to its simplicity and effectiveness in providing a single score to reflect a user's overall satisfaction with a system. Option A refers to ISO's definition of usability testing, B describes a task in usability testing, and D refers to a usability requirement, not SUS. Therefore, the correct description of SUS is option C.

NEW QUESTION # 24
A "usability requirement" is:
- A. A requirement how to conduct a usability test
- B. A requirement needed for a usability tester
- C. A requirement needed to define the size of a mobile phone used in a usability test
- D. A requirement on the usability of a component or system
Answer: D
Explanation:
A usability requirement specifies how usable a product or component must be, often in terms of effectiveness, efficiency, and user satisfaction, as defined in ISO 9241-11. These requirements ensure that the product meets specific human-centered design goals, such as allowing users to complete tasks accurately and quickly.
Options A and C describe procedural or test setup elements, not actual usability requirements. Option B refers to personnel qualifications, which are not the same as usability requirements related to system behavior or performance.

NEW QUESTION # 25
A large customer complained that a business application developed by your company sometimes transfers the wrong amount of money to clients, although there are no complaints of the actual users. The expected amount differs from the actually transferred amount by a factor of 10 or 100. After analyzing the log files, you found out that the application itself works fine. The problem seems to be caused by confusing text fields and labels for the decimal place, leading to user errors.
Which usability risk should be reasonably addressed for the next release?
- A. Users resist using a software product which is essential for their daily work because it lacks usability
- B. Users won't buy or use the software product because it lacks effectiveness, efficiency or satisfaction
- C. Users buy the software product but repeatedly need to call support because they don't understand how to use it
- D. Increased liability through risk to financial loss caused by a poorly designed or deceptive user interface
Answer: D
Explanation:
The scenario describes a situation where the interface misleads users into making serious financial mistakes due to poor design, such as confusing decimal separators. Even though the system functions correctly, it facilitates critical user errors. This constitutes a major usability risk with potential legal and financial consequences. Therefore, the correct risk to address is increased liability due to financial loss caused by a poorly designed or deceptive interface (option D). The other options focus on usability-related dissatisfaction, resistance, or lack of adoption, which are not the key concern in this scenario.

NEW QUESTION # 26
Which of the following are common mistakes made in usability testing?
i. The user is too active
ii. Critical results are ignored
iii. No observers involved
iv. Scheduling too late
v. Incorrect focus
- A. ii & iv are true, i, iii & v are false
- B. i & iii are true, ii, iv & v are false
- C. ii, iv & v are true, i & iii are false
- D. i, ii & iii are true, iv & v are false
Answer: C
Explanation:
Common mistakes in usability testing include:
Ignoring critical results (ii): A significant issue if findings are not acted upon.
Scheduling the test too late (iv): This can lead to usability problems being discovered too late to be addressed effectively.
Having the wrong focus (v): For instance, focusing on aesthetics instead of usability goals.
Option i ("user is too active") is not a problem-active participation is necessary. Option iii ("no observers involved") is not a typical mistake, since tests can still be valid even with recorded sessions and later review.
Hence, the correct answer is A: ii, iv & v are true.

NEW QUESTION # 27
Which of the following statements best describe Rapid Iterative Testing and Evaluation?
- A. Testing is quantitative
- B. Testing is informal and many potential users can be accessed
- C. Testing focuses on instant redesigns and confirming made changes
- D. Testing happens on a regular basis, e.g. each Monday
Answer: C
Explanation:
Rapid Iterative Testing and Evaluation (RITE) is a usability method in which usability issues are identified and addressed in short cycles. Unlike traditional usability testing, RITE allows for immediate redesigns and retesting of the improved version within the same study. The goal is to refine the design quickly based on observed usability issues. Option A confuses scheduling with methodology, B is too vague, and D inaccurately characterizes RITE as quantitative, while it is typically qualitative. Therefore, C accurately reflects the purpose and approach of RITE.

NEW QUESTION # 28
Usability reviews aim to identify potential usability problems based on certain criteria. Which of the following is a reasonable criterion for a usability review?
- A. Statutory Code of Practice
- B. Functional requirements
- C. Usability standards
- D. Opinion of the management
Answer: C
Explanation:
Usability reviews evaluate a system or interface against established usability principles or standards to identify potential issues before user testing. A recognized criterion for such reviews includes adherence to usability standards such as ISO 9241 or the Web Content Accessibility Guidelines (WCAG). These standards are derived from years of research and user-centered design principles. Options A and C do not directly relate to usability. Functional requirements (option B) refer to what the system should do, not how usable it is.
Hence, option D is correct as usability standards provide a consistent, objective basis for evaluating usability.

NEW QUESTION # 29
Which of the following elements are addressed by the WCAG?
i. Resizability of text
ii. Visually appealing design
iii. Text alternatives
iv. Keyboard accessibility
v. Mouse input
- A. i & iii are true, ii, iv & v are false
- B. i, ii, & iii are true, iv & v are false
- C. i, iii, iv & v are true, ii is false
- D. iv & v are true, i, ii & iii are false
Answer: C
Explanation:
The Web Content Accessibility Guidelines (WCAG) provide standards to ensure websites are accessible to people with disabilities. They specifically address:
i. Text resizability (SC 1.4.4),
iii. Text alternatives for non-text content (SC 1.1.1),
iv. Keyboard accessibility (SC 2.1.1),
v. Device independence, which includes not relying solely on mouse input.
Visually appealing design (ii) is not an accessibility requirement and is thus not a WCAG focus. The correct answer is D: i, iii, iv & v are true; ii is false.

NEW QUESTION # 30
A company distributes its products over a web shop where users can put items in their shopping cart. After they click on "checkout", the checkout process starts and users cannot go back anymore to correct possible mistakes. The only way is to hit the "back" button of the browser, which might lead to an expired session and therefore losing all items in the shopping cart.
Which of the following heuristics would best describe this usability issue?
- A. Visibility of system status
- B. User control and freedom
- C. Aesthetic and minimalist design
- D. Help and documentation
Answer: B
Explanation:
The described issue violates the usability heuristic "User control and freedom," as defined by Jakob Nielsen.
This principle emphasizes that users should have the ability to undo and redo actions and navigate freely without being trapped in irreversible sequences. In the scenario, users are forced into the checkout process without a clear way to return or correct mistakes, except through the unreliable and disruptive back button.
This design flaw undermines user autonomy and can result in lost progress or frustration.

NEW QUESTION # 31
What location is NOT suitable for conducting a usability test?
- A. A room where no action of the user can be seen or recorded by any means.
- B. A public place, such as a cafe.
- C. A room at the place where the test participant lives or works.
- D. Two office rooms that are connected by a video link.
Answer: A
Explanation:
The primary goal of usability testing is to observe and record user behavior while interacting with the system.
A location where user actions cannot be seen or recorded (option A) completely undermines the test's purpose and is therefore not suitable.
While options B, C, and D are not ideal in all cases, they can still be valid settings depending on the context.
Testing in a user's natural environment (B) increases ecological validity. Remote testing via video link (C) is widely accepted. Testing in a public setting (D) can be useful for mobile apps or services intended for real- world use.

NEW QUESTION # 32
Which of the following statements about usability test plans is true?
- A. It contains a schedule
- B. It contains the results of the test sessions
- C. It should be very elaborate and at least 10 pages
- D. It should contain the briefing instructions
Answer: A
Explanation:
A usability test plan is a foundational document created before conducting usability testing. It outlines the objectives, scope, methodology, participants, tasks, and schedule for the testing activities. One of its essential components is the schedule, which details when and how test sessions will occur to ensure proper resource allocation and time management. Including a schedule helps coordinate between test moderators, participants, observers, and stakeholders, making the testing process organized and efficient.
While briefing instructions (Option B) may be related to the usability test, they are typically documented separately or included in participant materials rather than the formal test plan itself. The test plan should be concise and focused; it need not be overly elaborate or lengthy (Option C), as clarity and usability of the plan are more important than length. The results of the test sessions (Option D) are not included in the test plan but rather compiled afterward in a test report or analysis document.
Therefore, the correct statement is that the usability test plan contains a schedule, ensuring a structured timeline for the usability testing activities.

NEW QUESTION # 33
A "usability test participant" ...
- A. ... helps to set up the system used for the usability test.
- B. ... is a person who observes a usability test.
- C. ... is a representative user who solves typical tasks in a usability test.
- D. ... can be the organizer of a usability test.
Answer: C
Explanation:
A usability test participant is a person selected to represent the target user group and asked to perform specific tasks in a usability test. Their actions, reactions, and feedback help identify usability issues and evaluate the system's effectiveness, efficiency, and user satisfaction. This role is strictly observational and does not involve organizing, observing, or setting up the test. Options A, B, and C describe other roles (e.g., technical support, observers, or moderators). Only option D accurately reflects the definition of a usability test participant.

NEW QUESTION # 34
What does the Equality Act address?
- A. It states that websites have to adhere to the WCAG conformity level AA
- B. It states that websites have to adhere to the WCAG conformity level A
- C. It obligates organizations to make sites accessible at all costs
- D. It protects people from discrimination in the workplace and in wider society
Answer: D
Explanation:
The Equality Act 2010 (UK) is legislation designed to protect individuals from discrimination in various areas, including employment and access to goods and services-this includes digital products like websites.
While it does not directly mandate WCAG compliance levels (A or AA), it implies that digital services must be accessible to users with disabilities. Organizations are required to make "reasonable adjustments" to avoid discrimination. Therefore, the most accurate and comprehensive answer is B.

NEW QUESTION # 35
What is good accessibility?
- A. Good usability of a software product by people with limited vision, hearing, dexterity, cognition or physical mobility
- B. Good usability regardless of disturbances like bright sunlight, noise or wind
- C. Good usability of a software product by people with limited knowledge of the software
- D. Good usability of a software product on all devices (smart phone, computer, etc.)
Answer: A
Explanation:
Accessibility refers to designing products so that people with disabilities or limitations (permanent or temporary) can use them effectively. According to the Web Content Accessibility Guidelines (WCAG) and ISO standards, accessibility focuses on ensuring that users with vision, hearing, cognitive, or mobility impairments can access digital interfaces. Option D captures this intent accurately. The other options relate to general usability or responsiveness (e.g., device adaptability or user experience in noisy environments) but do not address the inclusive nature of accessibility as defined by official guidelines.

NEW QUESTION # 36
Which of the following is the highest WCAG conformance level, promising the most accessible content?
- A. Single A (A)
- B. Quadruple A (AAAA)
- C. Triple A (AAA)
- D. Double A (AA)
Answer: C
Explanation:
The Web Content Accessibility Guidelines (WCAG) define three levels of conformance for web content accessibility:
Level A (Single A) is the minimum level of compliance.
Level AA (Double A) is the standard recommended for most websites, balancing accessibility and design.
Level AAA (Triple A) is the highest and most comprehensive level of accessibility, covering the widest range of needs.
There is no such level as "Quadruple A (AAAA)," making option D invalid.
Thus, WCAG Triple A (AAA) promises the most accessible content, even though it may not always be practically achievable for all types of content.
