Top 80+ Solved Unified Modeling Language (UML) MCQ Questions Answer

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

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

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

a. a transition is a change from one state to another

b. transitions may be spontaneous, but usually some event triggers them

d. all of the mentioned

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;

d. all of the mentioned

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
