  • all of the mentioned
Answer: all of the mentioned
Explaination:
these golden rules actually form the basis for a set of user interface design principles that guide this important software design activity.
Q8 | . Which of the following is not a design principle that allow the user to maintain control?
  • provide for flexible interaction
  • allow user interaction to be interrupt-able and undo-able
  • show technical internals from the casual user
  • design for direct interaction with objects that appear on the screen
Answer: show technical internals from the casual user
Explaination:
the user interface should move the user into the virtual world of the application.
Q9 | . Which of the following is not a user interface design process?
  • user, task, and environment analysis and modeling
  • interface design
  • knowledgeable, frequent users
  • interface validation
Answer: knowledgeable, frequent users
Explaination:
these are the end user for whom the product is being built.
Q10 | . When users are involved in complex tasks, the demand on __________ can be significant.
  • short-term memory
  • shortcuts
  • objects that appear on the screen
  • all of the mentioned
Answer: short-term memory
Explaination:
the interface should be designed to reduce the requirement to remember past actions and results.
Q11 | . Which of the following option is not considered by the Interface design?
  • the design of interfaces between software components
  • the design of interfaces between the software and human producers and consumers of information
  • c) the design of the interface between two computers
  • d) all of the mentioned
Answer: c) the design of the interface between two computers
Explaination:
the answer is self explanatory
Q12 | . A software might allow a user to interact via
  • keyboard commands
  • mouse movement
  • c) voice recognition commands
  • d) all of the mentioned
Answer: d) all of the mentioned
Explaination:
all the mentioned input mediums are available today.
Q13 | . A software engineer designs the user interface by applying an iterative process that draws on predefined design principles.
  • true
  • false
Answer: true
Explaination:
the statement is true.
Q14 | . What incorporates data, architectural, interface, and procedural representations of the software?
  • design model
  • user’s model
  • c) mental image
  • d) system image
Answer: design model
Explaination:
the requirements specification may establish certain constraints that help to define the user of the system,
Q15 | . What establishes the profile of end-users of the system?
  • design model
  • user’s model
  • c) mental image
  • d) system image
Answer: user’s model
Explaination:
to build an effective user interface, all design should begin with an understanding of the intended users,
Q16 | . What combines the outward manifestation of the computer-based system , coupled with all supporting information that describe system syntax and semantics?
  • mental image
  • interface design
  • c) system image
  • d) interface validation
Answer: c) system image
Explaination:
when the system image and the system perception are coincident, users generally feel comfortable with the software and use it effectively.
Q17 | . What do you understand by V&V in software testing?
  • verified version
  • version validation
  • c) verification and validation
  • d) version verification
Answer: c) verification and validation
Explaination:
v&v generally refers to any activity that attempts to ensure that the software will function as required.
Q18 | . In static test techniques, behavioral and performance properties of the program are observed.
  • true
  • false
Answer: false
Explaination:
static analysis techniques are based solely on the (manual or automated) examination of project documentation of software models and code.
Q19 | . Which granularity level of testing checks the behavior of module cooperation?
  • unit testing
  • integration testing
  • c) acceptance testing
  • d) regression testing
Answer: integration testing
Explaination:
integration testing is the phase in software testing in which individual software modules are combined and tested as a group.
Q20 | Which test refers to the retesting of a unit, integration and system after modification, in order to ascertain that the change has not introduced new faults?
  • regression test
  • smoke test
  • alpha test
  • beta test
Answer: regression test
Explaination:
regression test seeks to uncover new software bugs in existing functional and non-functional areas of a system after changes have been made to them.

  • test case
  • c) test document
  • d) test suite
Answer: test case
Explaination:
the answer is self explanatory.
Q23 | . In which test design each input is tested at both ends of its valid range and just outside its valid range?
  • boundary value testing
  • equivalence class partitioning
  • c) boundary value testing and equivalence class partitioning
  • d) decision tables
Answer: boundary value testing
Explaination:
boundary value analysis is a software testing technique in which tests are designed to include representatives of boundary values.
Q24 | . A white box test scales up well at different granularity levels of testing.
  • true
  • false
Answer: false
Explaination:
a white box test is mostly applicable at unit and integration testing level.
Q25 | . When does the testing process stops?
  • when resources (time and budget) are over
  • when some coverage is reached
  • c) when quality criterion is reached
  • d) testing never ends.
Answer: c) when quality criterion is reached
Explaination:
as software testing is an exhaustive process, when the quality assurance is established and the product is ready to be delivered, testing is stopped.
