NEW QUESTION # 24
As an expert for usability, you're in charge of the usability part of the development of a business application for a large customer. You have worked as a usability expert with the development team for two years and are operating well together; the developers value your feedback and give their bests implementing your suggestions. The product is in an early stage, so there's only a rudimentary prototype available.
Given this information, what is the best approach to verify the usability at the current stage?
- A. Usability maturity assessment
- B. Usability review
- C. Unmoderated usability test
- D. Usability test in the lab
Answer: B
Explanation:
At an early development stage where only a rudimentary prototype exists, a usability review (e.g., expert or heuristic review) is the most effective method. It allows usability specialists to identify potential usability issues without the need for a fully functioning product. Reviews can provide immediate, actionable feedback to guide design improvements before moving into more resource-intensive usability testing. An unmoderated usability test (B) or lab test (D) may be impractical at this stage due to limited interactivity. A usability maturity assessment (C) evaluates organizational processes and is not applicable to evaluating a specific prototype.

NEW QUESTION # 25
Which of the following is the highest WCAG conformance level, promising the most accessible content?
- A. Single A (A)
- B. Quadruple A (AAAA)
- C. Double A (AA)
- D. Triple A (AAA)
Answer: D
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.

NEW QUESTION # 26
Your project manager asked you for your advice. A recent project failed because the users were not satisfied with the final product, although your project manager claimed that she followed the human-centered design process. She interviewed users at the start of the project, created a first prototype and evaluated that prototype.
Which part of the human-centered design process did she miss?
- A. The "iterate"-part
- B. The "evaluate"-part
- C. The "design"-part
- D. The "analyze"-part
Answer: A
Explanation:
The human-centered design process emphasizes iterative development-testing and refining designs through multiple cycles. In the scenario, the project manager interviewed users and evaluated a prototype but did not iterate based on feedback. Skipping iteration likely resulted in unmet user needs. Human-centered design, per ISO 9241-210, includes: understanding context of use, specifying requirements, producing design solutions, and evaluating-repeated iteratively. Hence, option D ("iterate") is correct.

NEW QUESTION # 27
Which of the following are advantages of using a usability lab?
i. The context is natural
ii. Test sessions are easy to observe
iii. Inexpensive setup
iv. Similar conditions for all sessions
v. Easy recording of sessions
- A. iii, iv & v are true, i & ii are false
- B. ii & iv are true, i, iii & v are false
- C. i, ii & v are true, iii & iv are false
- D. ii, iv & v are true, i & iii are false
Answer: D
Explanation:
Usability labs provide a controlled environment that offers several advantages for observing and recording usability test sessions. Specifically, they allow for easy observation of participants (ii), standardized conditions for each session (iv), and facilitate audio and video recording for detailed analysis (v). However, the context is not natural (i), because the lab is an artificial setting rather than the user's actual environment.
Also, setting up a professional usability lab is not inexpensive (iii); it typically involves significant costs for equipment, space, and staffing. Therefore, options ii, iv, and v are true, while i and iii are false.

NEW QUESTION # 28
What is the System Usability Scale (SUS)?
- A. 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.
- B. A simple, ten-item attitude scale giving a global view of subjective assessments of usability.
- C. A requirement on the usability of a component of system
- D. 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.
Answer: B
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 # 29
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. i & iii are true, ii, iv & v are false
- B. ii & iv are true, i, iii & 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 # 30
What's the difference between an informal usability review and an expert usability review?
- A. No formal usability qualifications are required for an informal usability review
- B. Contrary to an expert review, an informal usability review is based on opinion
- C. An expert usability review is a formal review, not an informal review
- D. An informal review only requires one reviewer
Answer: A
Explanation:
An informal usability review can be conducted by anyone, including stakeholders or developers, and does not require formal usability training or qualifications. It is typically subjective and based on general impressions.
In contrast, an expert usability review (also called heuristic evaluation) is conducted by a trained usability expert who applies recognized usability principles. This is what differentiates the two approaches most clearly. Options A and C are misleading; expert reviews can be informal in format, and informal reviews aren't necessarily based solely on opinion. Option D is incorrect since both informal and expert reviews can be conducted individually or in groups.

NEW QUESTION # 31
Which of the following statements about usability testing is true?
- A. A usability test consists of one usability test session
- B. The preparation of a usability test is optional
- C. Before the usability test sessions, a pilot usability test session can be conducted
- D. The conditions under which a usability test is done are irrelevant
Answer: C
Explanation:
A pilot usability test session is a critical step prior to conducting the actual usability test. Its purpose is to ensure that the test setup, task design, and moderator instructions are clear and function as expected.
According to ISO 9241-210 and the Nielsen Norman Group's best practices, pilot testing helps detect unforeseen issues and fine-tune the process. Options A and B are incorrect because testing conditions must reflect realistic scenarios, and thorough preparation is essential to gather meaningful usability data. Option D is also incorrect; a usability test typically consists of multiple sessions with different users to gather sufficient data for analysis. The pilot session ensures everything works smoothly before involving real participants.

NEW QUESTION # 32
You're redesigning the web shop of a customer and found out that they are using legacy web design techniques like HTML tables for design matters, making the website hard to be operated using alternative input and output devices (e.g. screen readers).
Which kind of risk is most likely to occur?
- A. User experience risk
- B. There's no risk predictable
- C. Usability risk
- D. Accessibility risk
Answer: D
Explanation:
The use of HTML tables for layout instead of proper semantic HTML and responsive design violates accessibility guidelines, particularly those defined in the Web Content Accessibility Guidelines (WCAG).
Such a design makes it difficult or impossible for users relying on screen readers, keyboard navigation, or other assistive technologies to interact effectively with the site. Therefore, this creates a significant accessibility risk, which is distinct from general usability or user experience risks. Accessibility ensures inclusion of users with physical or cognitive impairments, making option B the correct choice.

NEW QUESTION # 33
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, iii, iv & v are true, ii is false
- C. iv & v are true, i, ii & iii are false
- D. i, ii, & iii are true, iv & v are false
Answer: B
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 # 34
Your last 20-pages usability test report wasn't received well by the developers; only two of the 25 usability problems have been fixed. This time, you want to stick to the best practices in order to obtain better acceptance by the development team.
What are you going to do differently this time?
- A. Make the report more detailed and longer
- B. Add the low-priority findings you didn't include in the first report
- C. Include contact details of the test participants so that the development team can contact them in case they have questions
- D. Include positive findings in the report, not only usability problems
Answer: D
Explanation:
Usability test reports are more effective when they are balanced and include not only problems but also what worked well. Including positive findings increases credibility, encourages the development team, and helps them understand what should remain unchanged. Option B violates privacy and ethical standards. Option C may dilute focus, and D could worsen the problem by making the report less accessible. Thus, the best practice supported by usability.gov and Nielsen Norman Group is to include both positive and negative findings.

NEW QUESTION # 35
Which of the following is a key activity in a usability test session?
- A. Test the set up and modify the test script if needed
- B. Talk to the participant during the completion of a task
- C. Moderate the usability test
- D. Extract usability findings and recommendations
Answer: C
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 # 36
Which of the following is the correct distinction between formative and summative usability evaluation?
- A. Summative evaluations mostly rely on user tests, formative evaluations require experts
- B. Summative evaluations assess the outcome, formative evaluations focus on improvement
- C. Summative evaluations focus on improvement, formative evaluations assess the outcome
- D. Summative evaluations mostly rely on experts, formative evaluations require users
Answer: B
Explanation:
Formative usability evaluation is conducted during the development process to identify usability problems and improve the product iteratively. It is diagnostic and improvement-focused. Summative evaluation, on the other hand, is done after development to assess the final product's usability, measuring how well it meets defined usability goals. Therefore, the correct distinction is that formative evaluation focuses on improvement, and summative evaluation assesses the outcome. This distinction aligns with widely accepted models such as those defined by ISO 9241-210 and usability.gov.

NEW QUESTION # 37
Which of the following is a principal task of the usability test moderator role?
- A. Create a survey plan
- B. Write a usability test plan
- C. Define testing tasks
- D. Log usability problems
Answer: C
Explanation:
The usability test moderator plays a crucial role during the execution phase of a usability test. Their principal task is to facilitate the test sessions by guiding participants through predefined testing tasks, observing behaviors, and ensuring that the test environment is neutral and free from bias. Defining testing tasks, however, is primarily done during the test design phase by the usability test designer or analyst, but the moderator ensures these tasks are clearly communicated and administered to participants during the session.
Logging usability problems (option B) is often done by observers or analysts reviewing session recordings or notes, not directly by the moderator during live testing. Creating a survey plan (option C) and writing the usability test plan (option D) are preparatory activities generally done before the test sessions and are not the moderator's main focus. Therefore, the principal role of the moderator centers on conducting the sessions and managing task delivery effectively to obtain authentic user interaction with the system under test.

NEW QUESTION # 38
A "usability test participant" ...
- A. ... can be the organizer of a usability test.
- B. ... is a representative user who solves typical tasks in a usability test.
- C. ... helps to set up the system used for the usability test.
- D. ... is a person who observes a usability test.
Answer: B
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 # 39
Which of the following statements best describe Rapid Iterative Testing and Evaluation?
- A. Testing focuses on instant redesigns and confirming made changes
- B. Testing happens on a regular basis, e.g. each Monday
- C. Testing is informal and many potential users can be accessed
- D. Testing is quantitative
Answer: A
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.
