Question 2

Kevin, the trainee analyst at Lynach TechSystems, is in charge of allocating suitable Unified Modeling Language (UML) notations to a particular class diagram.
-Which of the following relationships corresponds to the Unified Modeling Language (UML) notation on the class diagram 0..1 that Kevin has written?

Accepted Answer

The UML notation 0..1 corresponds to an optional relationship, where an object of the class on the side with 0..1 can either have no association or can be associated with one object of the class on the other side. In this case, an employee can have no spouse or one spouse, making option B the correct answer. Options A, C, and D correspond to different notations, such as 0..* for many direct reports or 1..1 for one office manager.

Question 9

Matching
​Identify the letter of the choice that best matches the phrase or definition.
-This shows the order in which the actions take place and identify the outcomes.

Accepted Answer

Activity diagrams are used to model the flow of activities or processes in a system, showing the order in which actions take place and identifying the outcomes.

Answer: B
 Business process models (BPM) are also used to model the flow of activities or processes in a system, showing the order in which actions take place and identifying the outcomes.

Answer: I
 The Unified Modeling Language (UML) is a standardized modeling language that includes various types of diagrams for modeling systems, including those that show the order of actions and outcomes (such as activity diagrams and sequence diagrams).

Note: None of the other choices directly match the given definition.

Question 10

Object modeling requires many types of diagrams, creating which by hand is very time consuming and tedious, so systems analysts rely on _____ to speed up the process.

Accepted Answer

CASE (Computer-Aided Software Engineering) tools are designed to support the software development process, including object modeling. They provide automated tools for diagram creation and can save time and effort for systems analysts. CRC (Class-Responsibility-Collaboration) modeling is a technique used for object-oriented design, but it is not a tool or software. Extreme Programming (XP) is a software development methodology that emphasizes collaboration, but it does not specifically relate to object modeling. Whiteboard sketches are a common tool for brainstorming and design ideation, but they are not automated and may not be suitable for creating formal diagrams for object modeling.

Question 14

Kevin, the trainee analyst at Lynach TechSystems, is in charge of allocating suitable Unified Modeling Language (UML) notations to a particular class diagram.
-In a given diagram, Kevin is designing a relationship in which a given employee can have no payroll deductions or he/she can have many deductions. Which of the following notations should Kevin write to mark this relationship?

Accepted Answer

The notation ​0..* signifies that an employee can have 0 or many payroll deductions, which is what is described in the scenario. The notation 0..1 would signify that an employee can have either 0 or 1 payroll deductions, which is not applicable here. The notations 1 and 1..* signify that an employee must have at least one payroll deduction, which is not valid either.

Question 15

Matching
​Identify the letter of the choice that best matches the phrase or definition.
-In a sequence diagram, an X marks the end of this.

Accepted Answer

In a sequence diagram, a lifeline represents the lifespan of an object or component, and an X on the end of the lifeline marks the end of that object's existence in the diagram.

Question 16

Matching
​Identify the letter of the choice that best matches the phrase or definition.
-In this, reading from left to right, the lines show direction and describe the action or event that causes a transition from one state to another.

Accepted Answer

This is a description of a state transition diagram, which shows the transitions between different states of an object or system.

Answer: B 
 Business process models (BPM) can also show the flow and direction of activities within a process.

Answer: F 
 An activity diagram can also show the flow and direction of activities within a process, but may not necessarily focus on state transitions as explicitly as a state transition diagram.

Question 17

Matching
​Identify the letter of the choice that best matches the phrase or definition.
-It is based on the idea that all data and methods are self-contained.

Accepted Answer

A "black box" is a concept where the internal workings are not visible or necessary to understand, focusing on inputs and outputs, similar to the idea of self-contained data and methods.

Question 18

Matching
​Identify the letter of the choice that best matches the phrase or definition.
-In this, lines show relationships between classes and have labels identifying the action that relates the two classes.

Accepted Answer

A class diagram shows relationships between classes and their attributes, as well as the actions that relate the classes to each other.

Answer: B 
 Business process models (BPM) are graphical representations of business processes, including the flow of information and the actions taken by different actors.

Answer: D 
 An object relationship diagram shows the relationships between different objects in a system, including their attributes and the actions that relate them to each other.

Answer: I 
 The Unified Modeling Language (UML) is a standardized language for visualizing, specifying, constructing, and documenting the artifacts of a software system.

Answer: G 
 Computer-aided software engineering (CASE) tools are software applications that support the development of software systems, including tools for modeling and diagramming.

Answer: J
