Question 1

Structure diagrams emphasize the things that must be present in the system being modeled.

Accepted Answer

Structure diagrams in software engineering and systems engineering focus on the static structure of the system, showing the system's classes, objects, or components, along with their relationships, attributes, and operations, but not defining the behavior.

Question 2

Which of the following diagram is time oriented?
A)collaboration
B)sequence
C)activity

Accepted Answer

Sequence diagrams are time-oriented because they show the order in which events occur.

Question 3

How many diagrams are here in Unified Modelling Language?
A)six
B)seven
C)eight
D)nine

Accepted Answer

Unified Modeling Language (UML) has nine diagrams. These include Class Diagram, Object Diagram, Use Case Diagram, Sequence Diagram, Collaboration Diagram, Activity Diagram, Statechart Diagram, Deployment Diagram, and Component Diagram.

Question 4

Which of the following is not needed to develop a system design from concept to detailed object-oriented design?
A)designing system architecture
B)developing design models
C)specifying interfaces
D)developing a debugging system

Accepted Answer

Developing a debugging system is not a part of developing a system design from concept to detailed object-oriented design. Debugging systems are typically developed or utilized after a design has been implemented in code to identify and fix errors, not during the design phase.

Question 5

Which of the following is a dynamic model that shows how the system interacts with its environment as it is used?
A)system context model
B)interaction model
C)environmental model
D)both system context and interaction

Accepted Answer

An interaction model is a dynamic model that illustrates how a system interacts with its environment during use.

Question 6

Which of the following is a structural model that demonstrates the other systems in the environment of the system being developed?
A)system context model
B)interaction model
C)environmental model
D)both system context and interaction

Accepted Answer

The System Context Model is designed to illustrate the other systems in the environment of the system being developed, showing how the system interacts with its external environment, including other systems and users.

Question 7

Which of the following come under system control?
A)reconfigure
B)shutdown
C)powersave
D)all of the mentioned

Accepted Answer

All the mentioned options, reconfigure, shutdown, and powersave, are actions that can be part of system control. System control encompasses a wide range of operations that manage the system's hardware and software resources, including its configuration, power management, and termination processes.

Question 8

We use _________ where various parts of system use are identified and analyzed in turn.
A)tangible entities
B)scenario-based analysis
C)design-based analysis
D)none of the mentioned

Accepted Answer

Scenario-based analysis is used to identify and analyze different parts of a system by examining various use scenarios.

Question 9

Which model describes the static structure of the system using object classes and their relationships?
A)sequence model
B)subsystem model
C)dynamic model
D)structural model

Accepted Answer

The structural model describes the static structure of the system using object classes and their relationships, focusing on the organization and composition of the classes, interfaces, and other elements that make up the system.

Question 10

Which model shows the flow of object interactions?
A)sequence model
B)subsystem model
C)dynamic model
D)both sequence and dynamic model

Accepted Answer

The answer of Which model shows the flow of object...

Question 11

If the system state is Shutdown then it can respond to which of the following message?
A)restart()
B)reconfigure()
C)powersave()
D)all of the mentioned

Accepted Answer

The system state Shutdown can respond to all of the mentioned messages (restart(), reconfigure(), and powersave()) because it is a state where the system is turned off and not running.

Question 12

Which message is received so that the system moves to the Testing state, then the Transmitting state, before returning to the Running state?
A)signalstatus()
B)remotecontrol()
C)reconfigure()
D)reportstatus()

Accepted Answer

The answer of Which message is received so that the...

Question 13

Open source development involves making the source code of a system publicly available.

Accepted Answer

Open source development is characterized by the practice of making the source code of a software system publicly available, allowing anyone to inspect, modify, and distribute the code.

Question 14

Which of the following is not the primary objectives in the analysis model?
A)describing the customer complaints
B)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

Accepted Answer

The primary objectives in the analysis model are to describe the customer complaints, establish a basis for the creation of a software design, and define a set of requirements that can be validated once the software is built. None of the mentioned options is not a primary objective in the analysis model.

Question 15

A description of each function presented in the DFD is contained in a ________.
A)data flow
B)process specification
C)control specification
D)data store

Accepted Answer

A process specification, or spec, in a Data Flow Diagram (DFD) provides a detailed description of how each process transforms its inputs into outputs, essentially explaining the logic behind each function.

Question 16

Which diagram indicates the behaviour of the system as a consequence of external events?
A)data flow diagram
B)state transition diagram
C)control specification diagram
D)workflow diagram

Accepted Answer

State transition diagrams are used to describe the behavior of a system as it responds to external events, showing how the system transitions from one state to another based on those events.

Question 17

A data model contains
A)data object
B)attributes
C)relationships
D)all of the mentioned

Accepted Answer

A data model typically includes data objects, attributes that define properties of data objects, and relationships among data objects, making all of the mentioned options correct.

Question 18

The __________ of a relationship is 0 if there is no explicit need for the relationship to occur or the relationship is optional.
A)modality
B)cardinality
C)entity
D)structured analysis

Accepted Answer

Modality refers to the necessity of a relationship in a data model. A modality of 0 indicates that the relationship is optional, meaning there is no explicit requirement for the relationship to occur.

Question 19

A _________ is a graphical representation that depicts information flow and the transforms that are applied as data moves from input to output.
A)data flow diagram
B)state transition diagram
C)control specification
D)workflow diagram

Accepted Answer

The answer of A _________ is a graphical representation that...

Question 20

A data condition occurs whenever a data is passed to an input element followed by a processing element and the result in control output.

Accepted Answer

A data condition occurs when a data is passed to an input element, followed by a processing element, and the result is a control output.
