Sequence diagrams Use cases
Domain model Package diagram
Package diagrams are designed for
Organizing a large project
into components
Assisting deployment
Reducing dependency None of these
Divide a complex system into small, self-contained pieces that can be managed
independency. How is it called?

Abstraction Modularity
Encapsulation Hierarchy
Which of these are part of class operations specification format?
Name Parameter list

Which statements are considered correct in reference to use case diagram?
A scenario is an interaction
between product and
particular interaction.
A use case diagram represents a
product's use cases and actors
involved in each use case
Both a and b None of the mentioned
What are true about a sequence diagram?
1. It describes the behavior in many use cases
2. It describes the behavior in a single use case.
3. It describes the behavior in a single object
4. It describes the behavior of several objects
1 and 2 1 and 3

What is true about UML stereotypes?
A stereotypes is used for
extending the UML language
A stereotypes class must be
abstract
The stereotype {frozen}
indicates that the UML
element cannot be changed
UML profiles can be stereotyped
for backward compatibility.
10) Which are valid events in a state diagram?
Else()
Close() After()
State whether true or false 04
Activity diagram can be used to explore/discover parallel activities.

super-class.
Association lines may be unlabeled or they may show association name.
An instance operation can be called using any object.
