NEW QUESTION # 10
What is a usability test task?
- A. 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
- B. 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
- 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 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: D
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 # 11
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. Include contact details of the test participants so that the development team can contact them in case they have questions
- B. Add the low-priority findings you didn't include in the first report
- C. Make the report more detailed and longer
- 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 # 12
Which of the following statements about usability test scripts is wrong?
- A. It contains answers to the test questions.
- B. It is a checklist used by the moderator of a usability test.
- C. It contains post-session interview questions.
- D. It contains pre-session interview questions.
Answer: A
Explanation:
A usability test script is a structured document used by the moderator to ensure consistency across test sessions. It typically includes pre-session briefing text, pre- and post-session interview questions, and the specific usability tasks to be performed. However, it does not include answers to the test questions, as usability tests focus on observing user behavior and performance-not testing users' knowledge. Providing answers would bias results and invalidate findings. Thus, option D is incorrect and the best choice.

NEW QUESTION # 13
Which of the following statements best describe Rapid Iterative Testing and Evaluation?
- A. Testing is informal and many potential users can be accessed
- B. Testing is quantitative
- 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 # 14
What is the System Usability Scale (SUS)?
- A. A simple, ten-item attitude scale giving a global view of subjective assessments of usability.
- 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 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: 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 # 15
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 "analyze"-part
- D. The "design"-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 # 16
A "usability test participant" ...
- A. ... is a person who observes a usability test.
- B. ... is a representative user who solves typical tasks in a usability test.
- C. ... can be the organizer of a usability test.
- D. ... helps to set up the system used for the 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 # 17
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, iv & v are true, ii is false
- B. i, ii, & iii are true, iv & v are false
- C. i & iii are true, ii, iv & v are false
- D. iv & v are true, i, ii & iii are false
Answer: A
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 # 18
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. iii, iv & v are true, i & ii are false
- C. ii, iv & v are true, i & iii are false
- D. i, ii & v are true, iii & iv 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 # 19
You are asked to evaluate the usability of a software application for a law firm. Due to time and budget constraints, it is not possible to include users in the evaluation process.
Which of the following is a valid approach for evaluating the usability in this case?
- A. User surveys
- B. Accessibility Evaluation
- C. Usability Review
- D. Usability testing
Answer: C
Explanation:
When actual users cannot be included, a usability review (often an expert or heuristic evaluation) is the most practical method. Trained evaluators examine the interface against usability principles and standards to identify potential issues. Surveys require user input, and usability testing cannot proceed without users.
Accessibility evaluation targets inclusivity for users with impairments, which is related but not a substitute for overall usability evaluation. Therefore, option A is the only valid method under these constraints.

NEW QUESTION # 20
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 review
- B. Unmoderated usability test
- C. Usability test in the lab
- D. Usability maturity assessment
Answer: A
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 # 21
In the last project, the usability tests substantially exceeded the budget of the test plan. Which quality control task could have been used to avoid this?
- A. Check that findings are communicated to the stakeholders
- B. Check consumed resources regularly and compare with the estimates
- C. Check whether the usability test report conforms to the best practices
- D. Check that the usability test plan has been properly reviewed
Answer: B
Explanation:
To prevent usability testing from exceeding budget, active monitoring and control of project resources are critical. The best practice is to regularly check consumed time, costs, and effort against the original estimates, allowing timely adjustments to scope or resources. This is a classic quality control practice aligned with ISO
9001 principles and standard project management methodologies. Option A relates to test preparation, option C concerns reporting and communication, and option D applies after test execution. Only option B deals directly with budget control during the test.

NEW QUESTION # 22
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 black-box test technique in which test cases are designed to execute usability scenarios.
- C. A document specifying a sequence of actions for the execution of a usability test.
- D. A period of time in which a usability test participant is executing tests, moderated by a moderator and observed by a number of observers.
Answer: D
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 # 23
Which of the following is the highest WCAG conformance level, promising the most accessible content?
- A. Triple A (AAA)
- B. Quadruple A (AAAA)
- C. Double A (AA)
- 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 # 24
You're defining usability test tasks for a web shop for mobile phones and smartphones. Finding out whether users are able to place an order easily has been identified as the main goal of the usability test.
Which of the following is a reasonable task definition to include in the test?
- A. Your phone broke and you're looking for a new smartphone. Your budget is 200$ and it should have an infrared sensor as you like to operate your home entertainment system with it. Find a suited smartphone and order it!
- B. Put the first phone you find in your shopping cart!
- C. Which mobile operating system do you prefer?
- D. Enter the item number "1469483" in the search box and click "OK". Put the first item in the cart by clicking "add to bag". Then, click on "checkout" in order to start the order process. After that, fill in the form and click on "submit".
Answer: A
Explanation:
Option B represents a realistic, goal-oriented scenario that reflects how an actual user would interact with the website. It incorporates context, user intent, constraints, and desired outcome-all characteristics of well- designed usability tasks. Option A is vague and lacks real-world motivation. Option C is too prescriptive and limits insight into user behavior, while D is a survey question, not a usability task. According to Nielsen Norman Group and ISO 25062, the best usability tasks are scenario-based, realistic, and outcome-driven- making B the correct answer.

NEW QUESTION # 25
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.
