NEW QUESTION # 18
What does the Equality Act address?
- A. It obligates organizations to make sites accessible at all costs
- B. It states that websites have to adhere to the WCAG conformity level A
- C. It protects people from discrimination in the workplace and in wider society
- D. It states that websites have to adhere to the WCAG conformity level AA
Answer: C
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 # 19
Which of the following is a principal task of the usability tester role?
- A. Define testing tasks
- B. Discuss findings from usability test
- C. Communicate with test participant
- D. Perform pre-session briefing of participants
Answer: C
Explanation:
The usability tester, often synonymous with the usability test moderator in practice, is primarily responsible for interacting directly with the test participants during the usability testing sessions. This role includes communicating with participants to guide them through test tasks, answering questions without leading responses, and ensuring the session runs smoothly. Effective communication is essential to facilitate participant comfort, elicit genuine user behaviors, and capture accurate usability data.
Performing the pre-session briefing (Option A) may be done by the usability tester but is often a shared responsibility or part of test facilitation protocols. Discussing findings (Option C) typically falls to analysts or usability experts after testing sessions are completed and data analyzed. Defining testing tasks (Option D) is usually done by test designers or analysts during test planning, not during the test execution.
Therefore, communicating with test participants during testing is a core, principal task of the usability tester role.

NEW QUESTION # 20
Which of the following is the best description for a usability test session?
- A. A test activity specified by the moderator that needs to be accomplished by a usability test participant within a given period of time.
- B. A period of time in which a usability test participant is executing tests, moderated by a moderator and observed by a number of observers.
- C. A black-box test technique in which test cases are designed to execute usability scenarios.
- D. A document specifying a sequence of actions for the execution of a usability test.
Answer: B
Explanation:
A usability test session is a controlled period during which a test participant performs tasks using the system under test while being observed by a moderator and sometimes additional stakeholders or observers. The goal is to understand how users interact with the interface and identify usability problems. Option A describes an individual task, not the whole session. Option C refers to a test plan or test script, and Option D describes a test technique rather than a usability session. Thus, option B provides the most accurate and comprehensive definition.

NEW QUESTION # 21
How can the approach for conducting user surveys be summarized best?
- A. Write survey plan, write schedule, select questionnaire, recruit users, remind users, communicate
- B. Write survey plan, interview users and stakeholders, select questionnaire, recruit users, remind users, communicate
- C. Write survey plan, write schedule, select questionnaire, recruit users, analyze, communicate
- D. Write survey plan, interview users and stakeholders, select questionnaire, deploy questionnaire, analyze, communicate
Answer: D
Explanation:
Conducting user surveys involves a structured approach that ensures data collection is effective, reliable, and meaningful. The process typically starts with writing a survey plan, which defines the objectives, scope, target population, and methodology. Next, interviewing users and stakeholders is important to gather qualitative insights, refine survey questions, and align the survey with business goals and user needs.
Selecting or designing the questionnaire follows, which includes crafting clear, unbiased questions to capture the desired data. After that, deploying the questionnaire to the recruited participants is essential; this can be done via email, online tools, or in-person, depending on the context. Once the data is collected, it must be analyzed to extract meaningful patterns, trends, and insights. Finally, communicating the findings to stakeholders completes the process by informing decision-making.
Other options miss critical steps such as deploying the questionnaire (Option C), or combine steps incorrectly (Options A and D). Importantly, the step of interviewing users and stakeholders prior to deployment ensures the survey is well-informed and targeted, enhancing the quality and relevance of data collected.

NEW QUESTION # 22
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. Help and documentation
- D. Aesthetic and minimalist design
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 # 23
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. iv & v are true, i, ii & iii are false
- B. i, iii, iv & v are true, ii is false
- C. i, ii, & iii are true, iv & v are false
- D. i & iii are true, ii, 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 # 24
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 requirement on the usability of a component of system
- D. A simple, ten-item attitude scale giving a global view of subjective assessments of usability.
Answer: D
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 # 25
Which of these basic approaches to a software development project follows all key elements of human- centered evaluation?
- A. Interview users, develop the software, and perform acceptance test
- B. Iteratively develop prototypes, perform expert reviews, and integrate found issues
- C. Define requirements, develop the software, and perform acceptance test
- D. Interview users, iteratively develop prototypes, and evaluate the software
Answer: D
Explanation:
Human-centered design, as defined by ISO 9241-210, emphasizes early user involvement, iterative design, and continuous usability evaluation. Option D aligns with this model as it begins with understanding user needs (interview users), proceeds through iterative prototyping (which allows for continuous improvement), and involves user evaluation. This ensures that the final product is shaped by real user input and feedback.
Options A and B lack iteration and continuous evaluation, while option C, although partially aligned, lacks explicit user involvement in the evaluation process, focusing only on expert reviews.

NEW QUESTION # 26
A "usability requirement" is:
- A. A requirement how to conduct a usability test
- B. A requirement needed to define the size of a mobile phone used in a usability test
- C. A requirement needed for a usability tester
- 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 # 27
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 "analyze"-part
- B. The "evaluate"-part
- C. The "design"-part
- D. The "iterate"-part
Answer: D
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 # 28
What's the difference between an informal usability review and an expert usability review?
- A. An informal review only requires one reviewer
- B. Contrary to an expert review, an informal usability review is based on opinion
- C. No formal usability qualifications are required for an informal usability review
- D. An expert usability review is a formal review, not an informal review
Answer: C
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 # 29
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 won't buy or use the software product because it lacks effectiveness, efficiency or satisfaction
- B. Users resist using a software product which is essential for their daily work because it lacks usability
- C. Increased liability through risk to financial loss caused by a poorly designed or deceptive user interface
- D. Users buy the software product but repeatedly need to call support because they don't understand how to use it
Answer: C
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 # 30
The usability team has written a usability test report. The report has the following structure:
Executive summary (1 page)
Table of contents (1 page)
Findings and recommendations (5 pages)
Objectives (2 pages)
Purpose (2 pages)
Contacts (1 page)
Which best practice does this usability test report violate?
- A. The report is too long
- B. The report makes use of usability jargon
- C. The report misses a description of the evaluation method
- D. The report misses positive findings
Answer: C
Explanation:
A best practice in usability reporting (based on ISO/IEC 25062:2006 - Common Industry Format for usability test reports) is to include a clear description of the evaluation method used. This includes how the test was designed, how participants were selected, what tasks were performed, and under what conditions the test was conducted. This ensures the results are credible and reproducible. The provided structure omits this essential information. While the report length is not excessive and positive findings may or may not be present, the key missing component is the method description.

NEW QUESTION # 31
Which of the following is the correct distinction between formative and summative usability evaluation?
- A. Summative evaluations assess the outcome, formative evaluations focus on improvement
- B. Summative evaluations focus on improvement, formative evaluations assess the outcome
- C. Summative evaluations mostly rely on user tests, formative evaluations require experts
- D. Summative evaluations mostly rely on experts, formative evaluations require users
Answer: A
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 # 32
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. i, ii & v are true, iii & iv are false
- C. ii, iv & v are true, i & iii are false
- D. ii & iv are true, i, iii & v are false
Answer: C
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 # 33
Which of the following statements about usability test plans is true?
- A. It should contain the briefing instructions
- B. It contains a schedule
- C. It contains the results of the test sessions
- D. It should be very elaborate and at least 10 pages
Answer: B
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.
