NEW QUESTION # 10
You're asked to evaluate the direct interaction between ordinary users and the software product. Which kinds of evaluations would be suited for that?
- A. Usability evaluation
- B. Accessibility evaluation
- C. Usability maturity assessment
- D. Risk assessment
Answer: A
Explanation:
A usability evaluation is specifically designed to assess how real users interact with a software product. It focuses on effectiveness, efficiency, and user satisfaction in completing tasks. This may involve usability testing, expert reviews, or heuristic evaluations. The goal is to identify any usability problems and understand user behavior during real use.
Option A (Accessibility evaluation) targets inclusivity for users with disabilities, not general user interaction.
Option B (Usability maturity assessment) evaluates the organization's usability practices, and Option C (Risk assessment) evaluates potential project or system risks. Only option D directly involves observing and measuring user interaction.

NEW QUESTION # 11
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 test in the lab
- B. Usability review
- C. Unmoderated usability test
- D. Usability maturity assessment
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 # 12
Which of the following is a key activity in a usability test session?
- A. Talk to the participant during the completion of a task
- B. Extract usability findings and recommendations
- C. Test the set up and modify the test script if needed
- 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 # 13
Which of the following is the highest WCAG conformance level, promising the most accessible content?
- A. Triple A (AAA)
- B. Double A (AA)
- C. Quadruple A (AAAA)
- D. Single A (A)
Answer: A
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 # 14
How can the approach for conducting user surveys be summarized best?
- A. Write survey plan, interview users and stakeholders, select questionnaire, deploy questionnaire, analyze, 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, write schedule, select questionnaire, recruit users, remind users, communicate
Answer: A
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 # 15
A "usability requirement" is:
- A. A requirement on the usability of a component or system
- 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 how to conduct a usability test
Answer: A
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 # 16
You're conducting a user survey and you have reached the third stage, selecting an appropriate questionnaire.
You have decided to use a standardized questionnaire as you want to benchmark against previous usability measurements.
Which of the following user questionnaires allow benchmarking against previous usability measurements?
i. SUS
ii. SUMI
iii. WAMMI
- A. i, ii and iii are true
- B. ii & iii are true, i is false
- C. i & ii are true, iii is false
- D. i is true, ii & iii are false
Answer: A
Explanation:
SUS (System Usability Scale), SUMI (Software Usability Measurement Inventory), and WAMMI (Website Analysis and Measurement Inventory) are all validated, standardized usability questionnaires that support benchmarking. They allow comparison against known usability scores from a wide variety of systems. These instruments provide numeric scores that can be interpreted using benchmark datasets or industry standards.
Therefore, all three-i, ii, and iii-are true, making D the correct answer.

NEW QUESTION # 17
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. Two office rooms that are connected by a video link.
- C. A room at the place where the test participant lives or works.
- D. A public place, such as a cafe.
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 # 18
What is the System Usability Scale (SUS)?
- A. A simple, ten-item attitude scale giving a global view of subjective assessments of usability.
- B. 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.
- C. 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.
- D. A requirement on the usability of a component of system
Answer: A
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 # 19
Which of the following is a principal task of the usability tester role?
- A. Perform pre-session briefing of participants
- B. Discuss findings from usability test
- C. Define testing tasks
- D. Communicate with test participant
Answer: D
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
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 misses a description of the evaluation method
- B. The report is too long
- C. The report misses positive findings
- D. The report makes use of usability jargon
Answer: A
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 # 21
What is a usability test task?
- 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. A test session in usability testing in which a usability test participant is executing tests, moderated by a moderator and observed by a number of observers
- C. A process through which information about the usability of a system is gathered in order to improve the system (known as formative evaluation) or to assess the merit or worth of a system (known as summative evaluation)
- D. A document specifying a sequence of actions for the execution of a usability test. It is used by the moderator to keep track of briefing and pre-session interview questions, usability test tasks, and post- session interview questions
Answer: A
Explanation:
A usability test task is a clearly defined activity that a participant is asked to perform during a usability test session. These tasks are typically created by the test designer or moderator and are designed to reflect realistic user goals (e.g., "Find and buy a product"). The purpose is to observe the participant's interaction with the system and identify usability issues. Option A describes a usability test script, not a task. Option C defines usability evaluation in general, and D refers to a session, not a specific task. Therefore, B is correct.

NEW QUESTION # 22
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. Add the low-priority findings you didn't include in the first report
- B. Include positive findings in the report, not only usability problems
- C. Include contact details of the test participants so that the development team can contact them in case they have questions
- D. Make the report more detailed and longer
Answer: B
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 # 23
Which of the following is a principal task of the usability test moderator role?
- A. Write a usability test plan
- B. Create a survey plan
- C. Log usability problems
- D. Define testing tasks
Answer: D
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 # 24
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. There's no risk predictable
- B. User experience risk
- 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 # 25
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. ii & iv are true, i, iii & v are false
- B. ii, iv & v are true, i & iii are false
- C. i, ii & v are true, iii & iv are false
- D. iii, iv & v are true, i & ii are false
Answer: B
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.
