QUESTION 1 According to ISO 9241-210, what is the definition of
"Usability"?
• A. The speed at which a user can complete a transaction on a
website
• B. The extent to which a system can be used by specified users to
achieve specified goals with effectiveness, efficiency, and
satisfaction in a specified context of use
• C. The visual appeal and aesthetic beauty of a user interface
• D. The total cost of ownership and maintenance of a software
product
Correct Answer: B. The extent to which a system can be used by
specified users to achieve specified goals with effectiveness, efficiency,
and satisfaction in a specified context of use
Detailed Rationale: ISO 9241-210 formally defines usability around
three core metrics: effectiveness, efficiency, and satisfaction within a
specific context of use.
QUESTION 2 What are the core components of the "Context of Use"
according to ISO standards?
• A. Users, tasks, equipment (hardware, software, materials), and
the physical and social environments
, • B. Server bandwidth, database capacity, and network latency
• C. Marketing budget, project timeline, and stakeholder
demographics
• D. Font styles, color palettes, and grid systems
Correct Answer: A. Users, tasks, equipment (hardware, software,
materials), and the physical and social environments
Detailed Rationale: The context of use encompasses the characteristics
of the users, the tasks they perform, the technical equipment used, and
the physical/social environment where interaction takes place.
QUESTION 3 What is the primary characteristic of a "Human-Centred
Design" (HCD) process as specified in ISO 9241-210?
• A. Design decisions are made exclusively by executive
management and software architects
• B. The process is iterative, focusing explicitly on the users, their
needs, and requirements throughout all stages of design and
development
• C. Development is completed in a single, rigid linear phase before
any user contact occurs
• D. Focus is placed primarily on minimizing database storage costs
Correct Answer: B. The process is iterative, focusing explicitly on the
users, their needs, and requirements throughout all stages of design
and development
,Detailed Rationale: Human-centred design requires continuous user
involvement, iterative refinement, and a multi-disciplinary approach to
problem solving.
QUESTION 4 Which of the following best defines "Effectiveness" in
usability metrics?
• A. The accuracy and completeness with which users achieve
specified goals
• B. The financial cost required to develop the software
• C. The mental effort exerted by the user during interaction
• D. The time elapsed from opening the app to closing it
Correct Answer: A. The accuracy and completeness with which users
achieve specified goals
Detailed Rationale: Effectiveness measures whether users successfully
accomplish their intended tasks without errors or incomplete
outcomes.
QUESTION 5 What does "Efficiency" measure in the context of usability
evaluation?
• A. The amount of computer memory consumed by the application
• B. Resources expended in relation to the accuracy and
completeness with which users achieve goals (e.g., time, effort,
cost)
• C. The number of customer support tickets submitted per month
• D. The percentage of users who recommend the product to others
, Correct Answer: B. Resources expended in relation to the accuracy and
completeness with which users achieve goals (e.g., time, effort, cost)
Detailed Rationale: Efficiency evaluates how economically users can
achieve their goals in terms of time, physical effort, and cognitive load.
QUESTION 6 How is "Satisfaction" defined in ISO 9241-210?
• A. The compliance of software code with international security
standards
• B. Freedom from discomfort and positive attitudes towards the
use of the system
• C. The financial profitability of the software product for the
company
• D. The speed of customer complaint resolution
Correct Answer: B. Freedom from discomfort and positive attitudes
towards the use of the system
Detailed Rationale: Satisfaction is a subjective measure reflecting how
comfortable users feel and how positively they view their interaction
with the product.
QUESTION 7 According to CPUX principles, what is the first principle of
human-centred design?
• A. The design is based upon an explicit understanding of users,
tasks, and environments
• B. The design must feature dark mode and vibrant animations
• C. The design must be written in object-oriented programming
code
