Q1 | . Structure diagrams emphasize the things that must be present in the system being modeled.
  • true
  • false
Answer: true
Explaination:
since structure diagrams represent the structure they are used extensively in documenting the architecture of software systems
Q2 | . h of the following diagram is time oriented?

  • six
  • seven
  • c) eight
  • d) nine
Answer: d) nine
Explaination:
the nine uml diagrams include use-case, sequence, collaboration, activity, state-chart, deployment, class, object and component.
Q4 | . Which of the following is not needed to develop a system design from concept to detailed object-oriented design?
  • designing system architecture
  • developing design models
  • c) specifying interfaces
  • d) developing a debugging system
Answer: d) developing a debugging system
Explaination:
the debugging system is a part of testing phase.
Q5 | . Which of the following is a dynamic model that shows how the system interacts with its environment as it is used?
  • system context model
  • interaction model
  • c) environmental model
  • d) both system context and interaction
Answer: interaction model
Explaination:
the answer is self explanatory.
Q6 | . Which of the following is a structural model that demonstrates the other systems in the environment of the system being developed?
  • system context model
  • interaction model
  • c) environmental model
  • d) both system context and interaction
Answer: system context model
Explaination:
the context model of a system may be represented using associations. associations simply show that there are some relationships between the entities involved in the association.
Q7 | . Which of the following come under system control?
  • reconfigure
  • shutdown
  • c) powersave
  • d) all of the mentioned
Answer: d) all of the mentioned
Explaination:
functionalities are governed by the system.
Q8 | . We use _________ where various parts of system use are identified and analyzed in turn.
  • tangible entities
  • scenario-based analysis
  • c) design-based analysis
  • d) none of the mentioned
Answer: scenario-based analysis
Explaination:
use a scenario-based analysis where various scenarios of system use are identified and analyzed in turn.
Q9 | . Which model describes the static structure of the system using object classes and their relationships?
  • sequence model
  • subsystem model
  • c) dynamic model
  • d) structural model
Answer: d) structural model
Explaination:
important relationships that may be documented at this stage are generalization (inheritance) relationships, uses/used-by relationships, and composition relationships.
Q10 | . Which model shows the flow of object interactions?
  • sequence model
  • subsystem model
  • c) dynamic model
  • d) both sequence and dynamic model
Answer: sequence model
Explaination:
sequence model are represented using a uml sequence or a collaboration diagram and are dynamic models
Q11 | . If the system state is Shutdown then it can respond to which of the following message?
  • restart()
  • reconfigure()
  • c) powersave()
  • d) all of the mentioned
Answer: d) all of the mentioned
Explaination:
a restart() message causes a transition to normal operation. both the powersave() and reconfigure() messages cause a transition to a state in which the system reconfigures itself.
Q12 | . Which message is received so that the system moves to the Testing state, then the Transmitting state, before returning to the Running state?
  • signalstatus()
  • remotecontrol()
  • c) reconfigure()
  • d) reportstatus()
Answer: d) reportstatus()
Explaination:
the answer is self explanatory.
Q13 | . Open source development involves making the source code of a system publicly available.
  • true
  • false
Answer: true
Explaination:
this means that many people can propose changes and improvements to the software.
Q14 | . Which of the following is not the primary objectives in the analysis model?
  • describing the customer complaints
  • establishing a basis for the creation of a software design
  • c) defining a set of requirements that can be validated once the software is built
  • d) none of the mentioned
Answer: d) none of the mentioned
Explaination:
all the options are covered in analysis model.
Q15 | . A description of each function presented in the DFD is contained in a ________.
  • data flow
  • process specification
  • c) control specification
  • d) data store
Answer: process specification
Explaination:
the answer is self explanatory.
Q16 | . Which diagram indicates the behaviour of the system as a consequence of external events?
  • data flow diagram
  • state transition diagram
  • c) control specification diagram
  • d) workflow diagram
Answer: state transition diagram
Explaination:
the state transition diagram represents the various modes of behavior (called states) of the system and the manner in which transitions are made from state to state.
Q17 | . A data model contains
  • data object
  • attributes
  • c) relationships
  • d) all of the mentioned
Answer: d) all of the mentioned
Explaination:
the data object,
Q18 | . The __________ of a relationship is 0 if there is no explicit need for the relationship to occur or the relationship is optional.
  • modality
  • cardinality
  • c) entity
  • d) structured analysis
Answer: modality
Explaination:
the modality is 1 if an occurrence of the relationship is mandatory, else 0 for optional relationship.
Q19 | . A _________ is a graphical representation that depicts information flow and the transforms that are applied as data moves from input to output.
  • data flow diagram
  • state transition diagram
  • c) control specification
  • d) workflow diagram
Answer: state transition diagram
Explaination:
the basic form of a data flow diagram, also known as a data flow graph or a bubble chart.
Q20 | . A data condition occurs whenever a data is passed to an input element followed by a processing element and the result in control output.
  • true
  • false
Answer: true
Explaination:
standard flow of condition check.
Q21 | . The __________ enables the software engineer to develop models of the information domain and functional domain at the same time
  • data flow diagram
  • state transition diagram
  • c) control specification
  • d) activity diagram
Answer: data flow diagram

as the dfd is refined into greater levels of detail, the analyst performs an implicit functional decomposition of the system,
Q22 | . The __________ contains a state transition diagram that is a sequential specification of behavior.
  • data flow diagram
  • state transition diagram
  • c) control specification
  • d) workflow diagram
Answer: c) control specification
Explaination:
the control specification(cspec) describes the behavior of the system, but it gives us no information about
Q23 | .Which of the following is not a construct?
  • sequence
  • condition
  • repetition
  • selection
Answer: selection
Explaination:
sequence implements processing steps that are essential in the specification of any algorithm.
Q24 | . Which of the following steps is applied to develop a decision table?
  • list all actions that can be associated with a specific procedure
  • list all conditions during execution of the procedure.
  • c) define rules by indicating what action(s) occurs for a set of conditions.
