Question 5

Which of these statements states Generalization connector?
A)a generalization connector is more like a link line between objects than an association line between classes
B)the generalization connector always indicates that two particular classes participate in the generalization relation, as a link line shows that two objects participate in a particular relation
C)never place a name, role names, or multiplicities on a generalization connector
D)all of the mentioned

Accepted Answer

All the statements describe characteristics of a generalization connector, including its similarity to a link line, its indication of class participation, and the absence of names, role names, or multiplicities.

Question 6

A provided interface can be shown in which of these ways?
A)to attach the stick of an interface lollipop symbol to a class or component
B)to connect a stereotyped class symbol representing the interface to the providing class or component using a special realization connector
C)both the ways mentioned above
D)none of the mentioned

Accepted Answer

Both methods mentioned are valid ways to show a provided interface in UML (Unified Modeling Language). The "interface lollipop" symbol is a common notation, and using a stereotyped class symbol with a realization connector is also an accepted approach.

Question 7

A required interface can be shown in which of the following ways?
A)to attach the stick of an interface socket symbol to a class or component
B)to connect the class or component requiring the interface to an interface ball with a dependency arrow
C)to connect the class or component to a stereotyped class symbol with a dependency arrow
D)all of the mentioned

Accepted Answer

All the mentioned options are valid ways to show a required interface in UML (Unified Modeling Language) diagrams. Each method provides a different visual representation to indicate that a class or component requires an interface to function.

Question 8

Which of the following is correct?
A)an attribute is an class variable when each object stores its own value for the attribute
B)an attribute can also be a instance variable, which means that there is only one value stored for the attribute that is shared by all class instances
C)an instance operation can be called using any object
D)a class operation is encapsulated in a class and can be called through the class

Accepted Answer

A class operation, also known as a class method, is encapsulated in a class and can be called through the class itself, not requiring an instance of the class.

Question 9

Which of the following is true?
A)the aggregation association represents the part-whole relation between the instances of the associated classes
B)in a composition association, each part can be related to only a single whole at one time
C)an association class represents a relation on the sets of instances of the classes it connects, and it also holds data and behavior the pertinent to the relation
D)all of the mentioned

Accepted Answer

All the statements provided are correct descriptions of different types of associations in object-oriented modeling. A) correctly describes aggregation, B) accurately describes composition, and C) correctly describes an association class.

Question 10

Which of the following are the heuristics for class diagram?
A)never place a name, role names, or multiplicities on a generalization connector
B)use the interface ball and socket symbols to abstract interface details and a stereotyped class symbol to show details.
C)don't italicize interface or operation names
D)all of the mentioned

Accepted Answer

All of the mentioned heuristics are for class diagrams.

Question 11

Which of the following is true?
A)a transition is a change from one state to another
B)transitions may be spontaneous, but usually some event triggers them
C)an event is a noteworthy occurrence at a particular time; events have no duration
D)all of the mentioned

Accepted Answer

All the statements provided are correct regarding transitions and events. A transition indeed is a change from one state to another, often triggered by an event, which is a noteworthy occurrence at a particular time and typically has no duration.

Question 12

Every finite automaton specification must contain which of the following?
A)descriptions of the automaton's states in a way that allows them to be distinguished, such as by naming each one;
B)descriptions of transitions indicating each transition's source state, its target state, and the events that trigger it;
C)designation of an initial state, the starting place for state transitions
D)all of the mentioned

Accepted Answer

Every finite automaton specification must include descriptions of the automaton's states, descriptions of transitions, and designation of an initial state. These elements are fundamental for defining the behavior and structure of a finite automaton.

Question 13

What does deterministic and non deterministic automaton?
A)a non-deterministic finite automaton is a finite automaton that has no spontaneous transitions and has a single transition that it must make in response to every event in each of its states
B)a deterministic finite automaton is one with multiple transitions
C)all of the mentioned
D)none of the mentioned

Accepted Answer

The provided options do not accurately define deterministic and non-deterministic automata. A deterministic finite automaton (DFA) has exactly one transition for each symbol in the alphabet from each state, ensuring a single possible path for any input string. A non-deterministic finite automaton (NFA) can have zero, one, or multiple transitions for each symbol in the alphabet from each state, allowing multiple possible paths for an input string. None of the options correctly describe these concepts.

Question 14

Which of the following determines state diagram?
A)the uml notation for specifying finite automata is the state diagram
B)in state diagrams, states are represented by rounded rectangles
C)all of the mentioned
D)none of the mentioned

Accepted Answer

Both A and B are correct. A state diagram is indeed a UML notation used for specifying finite automata, and within these diagrams, states are typically represented by rounded rectangles.

Question 15

Which of the following represents State Diagram?
A)the finite automaton initial state is designated by a special initial pseudo-state depicted as a large black dot at the tail of an arrow pointing at the initial state
B)a finite automaton may execute forever or it may halt in a final state
C)transitions are represented by solid arrows labeled with one or more transition strings that describe the circumstances under which the transition is triggered and the actions that may ensue
D)all of the mentioned

Accepted Answer

State diagrams, used to represent finite automata, include all the mentioned elements: an initial state indicated by a special symbol, the possibility of executing indefinitely or halting in a final state, and transitions depicted as arrows with labels describing the conditions and actions of the transition.

Question 16

Which of the following is true?
A)a state symbol without a nested state compartment represents a complex state
B)one with a nested state compartment represents a simple state
C)all of the mentioned
D)none of the mentioned

Accepted Answer

In UML (Unified Modeling Language), a state symbol without a nested state compartment typically represents a simple state, not a complex one. Conversely, a state with a nested state compartment indicates a composite state, which can contain substates, making it more complex. Therefore, both A and B are incorrect.

Question 17

Which of the following are composite states?
A)a sequential composite state
B)a concurrent composite state
C)all of the mentioned
D)none of the mentioned

Accepted Answer

Both sequential and concurrent composite states are types of composite states, which are used in state diagrams to represent complex behaviors that can be decomposed into simpler substates.

Question 18

What is sequential and concurrent composite state means?
A)a concurrent composite state contains a single state diagram composed of sub- states or inner states and the transitions between them
B)a sequential composite state contains two or more sequential state diagrams in regions separated by dashed lines called concurrent region boundary lines
C)all of the mentioned
D)none of the mentioned

Accepted Answer

The definitions provided in options A and B are incorrect. A concurrent composite state is one where regions can execute independently in parallel, not a single state diagram. A sequential composite state involves states that transition from one to another in a sequence, not multiple sequential diagrams separated by dashed lines.

Question 19

Sequential composite states simplify state models in two ways?
A)they organize states into hierarchies
B)they consolidate many transitions
C)all of the mentioned
D)none of the mentioned

Accepted Answer

Sequential composite states simplify state models by organizing states into hierarchies and consolidating many transitions, making the model easier to understand and manage.

Question 20

What is Interaction diagram?
A)interaction diagrams are the uml notations for dynamic modeling of collaborations
B)interaction diagrams are a central focus of engineering design
C)all of the mentioned
D)none of the mentioned
