Question 1

To reduce complexity, what can replace "looping constructs" in conditional statements?

A. Basic flow

B. In-line conditional behavior

C. Alternative flow

D. Scenario

Correct Answer: C

Question 2

Which of the following are the primary purposes for structuring the use-case model? (Select all that apply.)

A. Deciding on the flow of events of key use cases

B. Creating a use-case diagram

C. Simplifying the maintenance of the requirements

D. Achieve efficient and intuitive requirements reuse

Correct Answer: C,D

Question 3

Given: A developer is creating a use-case model for a banking system that contains use cases for Domestic Funds Transfer, International Funds Transfer, and Print Monthly Statement. The basic flow for each of these use cases starts the same -- prompt for identification, check the identification, and create a log-in session. The developer decides to simplify the flow of events for the use cases by removing the behavior that is the same in all three, and then consolidating that behavior in a separate use case called "Establish Session." What relationship must be created to relate the three existing use cases with the new "Establish Session" use case?

A. Dependency

B. Include

C. Extend

D. Generalization

Correct Answer: B

Question 4

What does a supplementary specification include?

A. <<include>> and <<extend>> relationships associated with a particular use case

B. Use-case diagram for the entire system

C. Non-functional requirements associated with a particular use case

D. Non-functional requirements associated with the entire system

Correct Answer: D

Question 5

What is a scenario?

A. A set of possible dialogs that can occur between the system and one or more actors

B. A specific dialog that can occur between the system and a particular actor

C. An ordered set of flows from the start of the use case to one of its end points

D. A description of the path the user takes through the use case and the data that is exchanged

Correct Answer: C

Question 6

What does the basic flow of events in a use case describe?

A. Least complicated interactions between the system and the actors

B. Interactions between the use case and other use cases

C. Typical use of the system by its actors

D. Choices an actor makes while interacting with the system

Correct Answer: C

Question 7

What technique can be used to control requirements from unofficial sources?

A. Link each software requirement to its source

B. Send requests for requirements through a standard approval process

C. Locate requirements in a single repository

D. Use an attribute to record the source of each requirement

Correct Answer: B

Question 8

The basic flow for each of these use cases starts the same -- prompt for identification, check the identification, and create a log-in session. The developer decides to simplify the flow of events for the use cases by removing the behavior that is the same in all three, and then consolidating that behavior in a separate use case called "Establish Session."

A. Dependency

B. Include

C. Extend

D. Generalization

Correct Answer: B

Question 9

Refer to the exhibit below. Which actors can interact with the "Distribute News" use case? (Select all that apply.)

A. Market trading system

B. Trading customer

C. News system

D. Scheduler

E. Broker

Correct Answer: B,C,D

Question 10

Which of the following are appropriate reasons for including an alternative flow of events in a use case? (Select all that apply.)

A. Actor must have previous information before the use case can begin

B. Actor can stop the use case at any time

C. Actor has several ways to accomplish a goal within the system

D. Actor requires 99.9% reliability

Correct Answer: B,C
