NEW QUESTION # 15
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 # 16
What is a usability test task?
- A. 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
- 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. 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 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
Answer: B
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 # 17
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. 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".
- B. Put the first phone you find in your shopping cart!
- C. 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!
- D. Which mobile operating system do you prefer?
Answer: C
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 # 18
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. Usability testing
- C. Accessibility Evaluation
- D. Usability Review
Answer: D
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 # 19
What location is NOT suitable for conducting a usability test?
- A. A public place, such as a cafe.
- B. A room where no action of the user can be seen or recorded by any means.
- 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: B
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 # 20
What is good accessibility?
- A. Good usability of a software product by people with limited knowledge of the software
- B. Good usability of a software product by people with limited vision, hearing, dexterity, cognition or physical mobility
- C. Good usability of a software product on all devices (smart phone, computer, etc.)
- D. Good usability regardless of disturbances like bright sunlight, noise or wind
Answer: B
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 # 21
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 are true, ii, iv & v are false
- C. i, ii, & iii are true, iv & v are false
- D. i, iii, iv & v are true, ii is false
Answer: D
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 # 22
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. Accessibility risk
- B. There's no risk predictable
- C. User experience risk
- D. Usability risk
Answer: A
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 # 23
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. Usability standards
- C. Opinion of the management
- D. Functional requirements
Answer: B
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 # 24
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 AA
- C. It states that websites have to adhere to the WCAG conformity level A
- 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 # 25
Why are positive usability findings of high importance? Which of the following statements is wrong?
- A. Positive usability findings make it easier to sell the need for correcting usability problems by giving a balanced view.
- B. Positive usability findings allow a better view of the usability of the product.
- C. Positive findings are of high importance because they can be used in the report to justify the costs of the test.
- D. Positive usability findings should be used to communicate to the development team which features should not be modified or deleted.
Answer: C
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 # 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. i, ii & iii are true, iv & v are false
- D. ii, iv & v are true, i & iii are false
Answer: D
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 is the best description for a usability test session?
- A. A document specifying a sequence of actions for the execution of a usability test.
- 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 test activity specified by the moderator that needs to be accomplished by a usability test participant within a given period of time.
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 # 28
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 positive findings in the report, not only usability problems
- B. Add the low-priority findings you didn't include in the first report
- C. Make the report more detailed and longer
- D. Include contact details of the test participants so that the development team can contact them in case they have questions
Answer: A
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 # 29
Which of the following statements about usability test scripts is wrong?
- A. It contains pre-session interview questions.
- B. It is a checklist used by the moderator of a usability test.
- C. It contains answers to the test questions.
- D. It contains post-session interview questions.
Answer: C
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 # 30
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 whether the usability test report conforms to the best practices
- C. Check consumed resources regularly and compare with the estimates
- D. Check that the usability test plan has been properly reviewed
Answer: C
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.
