NO.17 What is good accessibility?

Good usability regardless of disturbances like bright sunlight, noise or wind

Good usability of a software product on all devices (smart phone, computer, etc.)

Good usability of a software product by people with limited knowledge of the software

Good usability of a software product by people with limited vision, hearing, dexterity, cognition or physical mobility

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.

NO.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?

Usability Review

User surveys

Usability testing

Accessibility Evaluation

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.

NO.19 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?

Include positive findings in the report, not only usability problems

Include contact details of the test participants so that the development team can contact them in case they have questions

Add the low-priority findings you didn’t include in the first report

Make the report more detailed and longer

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.

NO.20 A “usability requirement” is:

A requirement needed to define the size of a mobile phone used in a usability test

A requirement needed for a usability tester

A requirement how to conduct a usability test

A requirement on the usability of a component or system

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.

NO.21 Which of these basic approaches to a software development project follows all key elements of human- centered evaluation?

Interview users, develop the software, and perform acceptance test

Define requirements, develop the software, and perform acceptance test

Iteratively develop prototypes, perform expert reviews, and integrate found issues

Interview users, iteratively develop prototypes, and evaluate the software

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.

NO.22 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?

Put the first phone you find in your shopping cart!

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!

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”.

Which mobile operating system do you prefer?

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.

NO.23 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

i, ii & v are true, iii & iv are false

ii, iv & v are true, i & iii are false

ii & iv are true, i, iii & v are false

iii, iv & v are true, i & ii are false

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.

NO.24 Which of the following statements about usability testing is true?

The conditions under which a usability test is done are irrelevant

The preparation of a usability test is optional

Before the usability test sessions, a pilot usability test session can be conducted

A usability test consists of one usability test session

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.

NO.25 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

i & iii are true, ii, iv & v are false

i, ii, & iii are true, iv & v are false

iv & v are true, i, ii & iii are false

i, iii, iv & v are true, ii is false

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.

NO.26 During a usability test, a user suggested that a quick search box on every page would help a lot for several of the main tasks. You added this finding to the list.
What’s the correct classification for these kinds of findings?

Positive finding

Usability problem

Good idea

Functional problem

In usability evaluations, a distinction is made between actual usability problems (where a user struggles to complete a task or is confused by the interface) and suggestions or ideas that users provide based on their preferences or perceived improvements. When a participant offers a new feature idea (such as a quick search box), this is classified as a “good idea” or “feature suggestion,” not necessarily a usability problem. It may inform future design enhancements but does not indicate a failure in usability for existing functionality.

NO.27 What does the Equality Act address?

It obligates organizations to make sites accessible at all costs

It protects people from discrimination in the workplace and in wider society

It states that websites have to adhere to the WCAG conformity level AA

It states that websites have to adhere to the WCAG conformity level A

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.

NO.28 Which of the following is the highest WCAG conformance level, promising the most accessible content?

Double A (AA)

Single A (A)

Triple A (AAA)

Quadruple A (AAAA)

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.

NO.29 Why are positive usability findings of high importance? Which of the following statements is wrong?

Positive usability findings make it easier to sell the need for correcting usability problems by giving a balanced view.

Positive findings are of high importance because they can be used in the report to justify the costs of the test.

Positive usability findings allow a better view of the usability of the product.

Positive usability findings should be used to communicate to the development team which features should not be modified or deleted.

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.

NO.30 Which of the following is a principal task of the usability tester role?

Perform pre-session briefing of participants

Communicate with test participant

Discuss findings from usability test

Define testing tasks

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.

NO.31 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

i is true, ii & iii are false

ii & iii are true, i is false

i & ii are true, iii is false

i, ii and iii are true

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.

NO.32 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?

Check that the usability test plan has been properly reviewed

Check consumed resources regularly and compare with the estimates

Check that findings are communicated to the stakeholders

Check whether the usability test report conforms to the best practices

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.
