Question 1

The _____ relationship in use cases allows use cases to support the concept of inheritance.
A) association
B) extend
C) include
D) generalization
E) none of the above

Accepted Answer

The generalization relationship in use cases allows use cases to support the concept of inheritance. Generalization is a relationship that is used to represent the relationship between a more general use case and a more specific use case. The more specific use case inherits the behavior and attributes of the more general use case. This relationship supports the principle of reuse and can reduce the complexity of use case diagrams.

Question 2

Which of the relationship types in use cases enables functional decomposition?
A) association relationship
B) extend relationship
C) include relationship
D) generalization relationship
E) decompose relationship

Accepted Answer

The "include" relationship in use cases is used for functional decomposition, allowing a use case to include the functionality of another use case. This helps in reusing the functionality and simplifying the overall structure.

Question 3

The event that causes a use case to begin is called a(n) _____.
A) action
B) trigger
C) hammer
D) anvil
E) stakeholder

Accepted Answer

The event that causes a use case to begin is called a trigger. It could be anything from a user action to a system event.

Question 4

A(n) _____ use case is typically created early in the process of understanding the system requirements as a way of documenting basic information about the use case.
A) overview
B) detail
C) essential
D) real
E) imaginary

Accepted Answer

An overview use case is created early in the process of understanding the system requirements as a way of documenting basic information about the use case. It provides a high-level view of the functionality of the system and helps to identify the actors, goals, and basic flow of events. It is created before the detailed use case, which provides more specific and detailed information about the use case. The essential use case focuses on the behaviors and interactions required for the system to meet its objectives, while the real use case describes the actual events that occur during the execution of the system. The imaginary use case is not a commonly used term in use case modeling.

Question 5

Which of the following diagramming symbols represents an actor in a use case diagram?
A)

B)

C)

D)

E)

Accepted Answer

Question 9

The importance level of a use case increases for all of the following characteristics of the use case EXCEPT _____.
A) the use case represents an important business process
B) the use case supports revenue generation
C) the technology is proven
D) the functionality is complex
E) the functionality is time-critical

Accepted Answer

The importance level of a use case increases for all of the listed characteristics except for "the technology is proven." While having proven technology may be beneficial for ease of implementation, it does not necessarily increase the importance of the use case. The other listed characteristics, such as supporting revenue generation, representing an important business process, or having complex or time-critical functionality, are all factors that can increase the importance level of a use case.

Question 10

Individual steps in a use case should be written in the form _____.
A) Direct Object, Verb, Subject, Preposition, Indirect Object
B) Direct Object, Subject, Verb, Preposition, Indirect Object
C) Subject, Verb, Preposition, Indirect Object, Direct Object
D) Subject, Verb, Indirect Object, Preposition, Direct Object
E) Subject, Verb, Direct Object, Preposition, Indirect Object

Accepted Answer

The individual steps in a use case should be written in the form of Subject, Verb, Direct Object, Preposition, Indirect Object. This format is known as the "Actor-Verb-Object" format and it helps to clearly describe the action being taken.

Question 11

Which of the following diagramming symbols represents a generalization relationship in a use case diagram? 
A)

B)

C)

D)

E)

Accepted Answer

The answer of Which of the following diagramming symbols represents...

Question 12

Which of the following relationships represent the extension of the functionality of the use case to cover optional behavior?
A) association relationship
B) extend relationship
C) include relationship
D) generalization relationship
E) optional relationship

Accepted Answer

The extend relationship represents the extension of the functionality of the use case to cover optional behavior. The extend relationship is used when the extension use case is optional and may or may not be included in the base use case. Therefore, it is the best choice for this scenario. The other choices are not relevant to the question or do not represent the extension of functionality for optional behavior.

Question 13

When drawing the use-case diagram, an analyst should do the steps in this order: _____.
A) draw the use cases on the diagram, identify the system boundary, place the actors on the diagram, and draw the lines connecting the actors to the use cases
B) identify the system boundary, draw the use cases on the diagram, place the actors on the diagram, and draw the lines connecting the actors to the use cases
C) place the actors on the diagram, draw the use cases on the diagram, identify the system boundary, and draw the lines connecting the actors to the use cases
D) identify the system boundary, place the actors on the diagram, draw the use cases on the diagram, and draw the lines connecting the actors to the use cases
E) none of the above gives the correct order of steps

Accepted Answer

The correct order is to first identify the system boundary, then draw the use cases, place the actors, and finally connect actors to use cases.

Question 14

If a use case becomes too complex, it should be _____.
A) rewritten to simplify it
B) decomposed into a set of use cases
C) written with a series of repeating steps to simplify it
D) written from the perspective of an independent observe to simplify it
E) dropped from the system, as it will be too complex to implement in the final system

Accepted Answer

If a use case becomes too complex, it is recommended to decompose it into smaller, more manageable use cases. This allows for better organization and understanding of the system's functionality. Rewriting the use case may not necessarily simplify it, and adding repeating steps may actually add to its complexity. Writing from the perspective of an independent observer may not necessarily address the complexity of the use case. Dropping the use case altogether may not be the best solution, as it may be a critical component of the system's functionality.

Question 15

Which of the following diagramming symbols represents a subject boundary in a use case diagram? 
A)

B)

C)

D)

E)

Accepted Answer

Symbol B represents a subject or system boundary in a use case diagram. It is used to identify the boundaries of the system or software being developed and to separate it from external actors or systems.

Question 16

A scenario is the same as a(n) _____.
A) use case
B) relationship
C) path through a use case
D) collection of use cases
E) role.

Accepted Answer

A scenario is a specific path through a use case, detailing a sequence of events that occur during one particular execution of the use case.
