compilation units or classes

their properties, relationship

interaction of units

all of the mentioned

all of the mentioned

none of the mentioned

Q4 | The DDD template consists of which of the following?

mid level design and low level design

mapping between models

detailed design rationale

all of the mentioned

Q5 | Which of these statements states Generalization connector?

a generalization connector is more like a link line between objects than an association line between classes

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

never place a name, role names, or multiplicities on a generalization connector

all of the mentioned

Q6 | A provided interface can be shown in which of these ways?

to attach the stick of an interface lollipop symbol to a class or component

to connect a stereotyped class symbol representing the interface to the providing class or component using a special realization connector

both the ways mentioned above

none of the mentioned

Q7 | A required interface can be shown in which of the following ways?

to attach the stick of an interface socket symbol to a class or component

to connect the class or component requiring the interface to an interface ball with a dependency arrow

to connect the class or component to a stereotyped class symbol with a dependency arrow

all of the mentioned

Q8 | Which of the following is correct?

an attribute is an class variable when each object stores its own value for the attribute

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

an instance operation can be called using any object

a class operation is encapsulated in a class and can be called through the class

Q9 | Which of the following is true?

the aggregation association represents the part-whole relation between the instances of the associated classes

in a composition association, each part can be related to only a single whole at one time

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

all of the mentioned

Q10 | Which of the following are the heuristics for class diagram?

never place a name, role names, or multiplicities on a generalization connector

use the interface ball and socket symbols to abstract interface details and a stereotyped class symbol to show details.

don’t italicize interface or operation names

all of the mentioned

Q11 | Which of the following is true?

a transition is a change from one state to another

transitions may be spontaneous, but usually some event triggers them

an event is a noteworthy occurrence at a particular time; events have no duration

all of the mentioned

Q12 | Every finite automaton specification must contain which of the following?

descriptions of the automaton’s states in a way that allows them to be distinguished, such as by naming each one;

descriptions of transitions indicating each transition’s source state, its target state, and the events that trigger it;

designation of an initial state, the starting place for state transitions

all of the mentioned

Q13 | What does deterministic and non deterministic automaton?

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

a deterministic finite automaton is one with multiple transitions

all of the mentioned

none of the mentioned

Q14 | Which of the following determines state diagram?

the uml notation for specifying finite automata is the state diagram

in state diagrams, states are represented by rounded rectangles

all of the mentioned

none of the mentioned

Q15 | Which of the following represents State Diagram?

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

a finite automaton may execute forever or it may halt in a final state

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

all of the mentioned

Q16 | Which of the following is true?

a state symbol without a nested state compartment represents a complex state

one with a nested state compartment represents a simple state

all of the mentioned

none of the mentioned

Q17 | Which of the following are composite states?

a sequential composite state

a concurrent composite state

all of the mentioned

none of the mentioned

Q18 | What is sequential and concurrent composite state means?

a concurrent composite state contains a single state diagram composed of sub- states or inner states and the transitions between them

a sequential composite state contains two or more sequential state diagrams in regions separated by dashed lines called concurrent region boundary lines

all of the mentioned

none of the mentioned

Q19 | Sequential composite states simplify state models in two ways?

they organize states into hierarchies

they consolidate many transitions

all of the mentioned

none of the mentioned

Q20 | What is Interaction diagram?

interaction diagrams are the uml notations for dynamic modeling of collaborations

interaction diagrams are a central focus of engineering design

all of the mentioned

none of the mentioned

Q21 | What are the different interaction diagram notations does UML have?

a sequence diagram

a communication diagram

an interaction overview diagram

all of the mentioned

Q22 | What is a sequence diagram?

a diagram that shows interacting individuals along the top of the diagram and messages passed among them arranged in temporal order down the page

a diagram that shows messages super imposed on a diagram depicting collaborating individuals and the links among them

a diagram that shows the change of an individual’s state over time

all of the mentioned

Q23 | Which of the following is true about Sequence frames?

a sequence diagram has a frame consisting of a rectangle with a pentagon inits upper left-hand corner

the pentagon is its name compartment ; the interaction is represented inside the rectangle.

the string in the name compartment has the form sd interaction identifier where interaction identifier is either a simple name or an operation specification with the same format as in a class diagram

all of the mentioned

Q24 | What is a lifeline?

it is a frame consisting of a rectangle with a pentagon inits upper left-hand corner

it is a rectangle containing an identifier with a dashed line extending below the rectangle

it is a name compartment ; the interaction is represented inside the rectangle

none of the mentioned

Q25 | What does a message mean?

it passes all communications from one object to another and are represented by message arrows in sequence diagrams

message goes from the sending object’s lifeline to the receiving object’s lifeline

it is a rectangle containing an identifier with a dashed line extending below the rectangle

all of the mentioned
