Sample Practice Questions

Try these 10 sample questions from the Certified Tester Usability Testing (CT-UT) practice bank. Each includes the answer and explanation. Continue with the interactive practice above to review the full question set.

1. 1A product passes every functional specification test, but intended users struggle to complete routine work. What conclusion about usability is justified?

   1. A. Specification compliance establishes that the usability is acceptable.
   2. B. Usability problems can remain despite specification compliance.
   3. C. Usability problems exist only when functions produce incorrect results.
   4. D. Usability can be assessed only after a specification defect is found.

   Answer: B

   Explanation: The syllabus states: "A software product can work exactly to specification and still have serious usability problems" Correct implementation of specified functions does not establish that users can use them successfully.

2. 2Which pair of factors is normally used to express a usability risk?

   1. A. The number of evaluators and the number of observations.
   2. B. The cost of evaluation and the number of interface controls.
   3. C. The impact of an event and its likelihood of occurring.
   4. D. The age of the product and the duration of its development.

   Answer: C

   Explanation: The syllabus states: "usually expressed as the impact (that is, harm resulting from the event), and the likelihood of the event happening." Risk combines the potential negative consequence with the chance that it will occur; activity counts and project attributes do not substitute for these factors.

3. 3What makes a user interface guideline useful for consistent implementation across an organization?

   1. A. It expresses a broad design goal that each designer interprets independently.
   2. B. It provides a specific rule or recommendation with little room for interpretation.
   3. C. It records users' subjective ratings without specifying interface behavior.
   4. D. It defines project milestones without constraining the resulting interface.

   Answer: B

   Explanation: ISTQB Foundation Level Specialist Syllabus — Usability Testing states: "A user interface guideline is a low-level, specific rule or recommendation for user interface design." Specific guidance enables consistent appearance and behavior. A broad principle leaves more interpretation, while ratings and milestones do not specify interface design.

4. 4Several reviewers have been selected for a usability review. What should they do before meeting to discuss their findings?

   1. A. Agree a joint findings list and then inspect the application to confirm it.
   2. B. Have the author approve potential findings before independent inspection.
   3. C. Divide the user groups so no reviewer considers the overall user perspective.
   4. D. Evaluate the application individually and record their own findings.

   Answer: D

   Explanation: The syllabus states: "The reviewers evaluate the software application in solitude and write down their findings." Independent evaluation precedes the meeting to reach consensus, reducing premature influence on each reviewer's findings.

5. 5What is the overall focus of usability testing?

   1. A. Checking whether each implemented function conforms to its functional specification.
   2. B. Evaluating specified users' effectiveness, efficiency, and satisfaction in a specified context.
   3. C. Checking the interface against a fixed visual style without considering its users.
   4. D. Evaluating users' general opinions without relating them to use of the system.

   Answer: B

   Explanation: The syllabus states: "Usability testing evaluates the degree to which the system can be used by specified users with effectiveness, efficiency and satisfaction in a specified context of use." The focus includes specified users and context as well as three usability components; functional compliance, style compliance, and unrelated opinions do not capture it.

6. 6Who should form the sample for a user survey evaluating experience with an existing system?

   1. A. Developers selected for their knowledge of the system's internal implementation.
   2. B. Potential customers who have seen advertisements but have never used the system.
   3. C. Representative users who can report their experience of using the system.
   4. D. Reviewers selected solely for expertise in general interface design principles.

   Answer: C

   Explanation: The syllabus states: "A user survey is a usability evaluation whereby a representative sample of users are asked to report subjective evaluation into a questionnaire based on their experience in using a component or system." The sample should represent actual users and their experience. Implementation expertise, advertisement exposure, or generic design expertise does not establish that representativeness.

7. 7A release criterion requires intended users to complete a specified workflow within a stated time limit. Representative users and suitable equipment are available. Which evaluation best provides evidence that this efficiency requirement has been fulfilled?

   1. A. A quantitative usability test measuring completion times under the stated conditions.
   2. B. An expert review estimating whether the workflow appears fast enough.
   3. C. A user survey asking whether users generally like the workflow.
   4. D. A qualitative review discussing terminology without collecting task measurements.

   Answer: A

   Explanation: The syllabus states: "To evaluate whether efficiency requirements have been fulfilled, or whether the usability of a product has measurably improved, use a quantitative usability test" A measured time criterion calls for quantitative task evidence. Estimates, satisfaction responses, or terminology discussions do not establish fulfillment.

8. 8A project assigns the usability tester, moderator, note-taker, and test participants as separate roles. Which role's principal tasks include writing the usability test plan?

   1. A. Usability test participant
   2. B. Note-taker
   3. C. Moderator
   4. D. Usability tester

   Answer: D

   Explanation: The syllabus states: "Write a usability test plan" The table assigns planning to the usability tester. The separately assigned moderator conducts sessions, the note-taker records and analyzes findings, and participants perform tasks.

9. 9Which description identifies the scope of a software product's user interface?

   1. A. The graphical controls used to enter data, excluding displayed information.
   2. B. The visual presentation of results, excluding controls used to act on them.
   3. C. The product components providing information and controls for users' tasks.
   4. D. The hardware devices supplying inputs, excluding software-provided controls.

   Answer: C

   Explanation: The syllabus states: "The user interface consists of all components of a software product that provide information and controls for the user to accomplish specific tasks with the system." Both information and controls belong to the interface; the narrower descriptions omit part of it.

10. 10Which distinction between product risks and project risks is correct?

    1. A. Product risks affect evaluation budgets; project risks affect users' task outcomes.
    2. B. Product risks concern existing failures; project risks concern future events.
    3. C. Product risks concern technical defects; project risks exclude usability objectives.
    4. D. Product risks affect product quality; project risks affect delivery of usability objectives.

    Answer: D

    Explanation: The syllabus states: "Project risks may impact a project’s capability to deliver its usability objectives." The adjacent product-risk definition concerns overall software quality. Both categories concern possible negative consequences, and project risks include usability delivery.
