Question 1

What can be requested from any object of the class to affect behavior&#10;A)object&#10;B)attribute&#10;C)operation&#10;D)instance

Accepted Answer

An operation can be requested from an object of a class to affect its behavior, as it defines the actions that the object can perform.

Question 2

Which diagram in UML emphasizes the time-ordering of messages&#10;A)activity&#10;B)sequence&#10;C)collaboration&#10;D)class

Accepted Answer

Sequence diagrams in UML are specifically designed to show the time-ordering of messages between objects, emphasizing the sequence of messages and interactions in a time-ordered manner.

Question 3

If you are working on real-time process control applications or systems that involve concurrent processing, you would use a&#10;A)activity diagram&#10;B)sequence diagram&#10;C)statechart diagram&#10;D)object diagram

Accepted Answer

Statechart diagrams are used to model the dynamic behavior of individual objects, which is crucial in real-time process control applications or systems involving concurrent processing. They help in visualizing the different states of an object and the transitions between these states, which is essential for understanding and designing the behavior of real-time and concurrent systems.

Question 4

Which diagram shows the configuration of run-time processing elements&#10;A)deployment diagram&#10;B)component diagram&#10;C)node diagram&#10;D)er-diagram

Accepted Answer

A deployment diagram in UML shows the physical deployment of artifacts on nodes. This includes the configuration of run-time processing elements and the physical connections between them.

Question 5

Which things in UML are the explanatory parts of UML models&#10;A)structural things&#10;B)behavioral things&#10;C)grouping things&#10;D)annotational things

Accepted Answer

Annotational things in UML are used to add explanations or comments to the models, providing additional information or clarification.

Question 6

What refers to the value associated with a specific attribute of an object and to any actions or side&#10;A)object&#10;B)state&#10;C)interface&#10;D)none of the mentioned

Accepted Answer

The state of an object refers to the value associated with a specific attribute of the object and can also relate to any actions or side effects that occur due to a change in an attribute's value.

Question 7

Which of the following is true for optional fragments&#10;A)an optional fragment is a portion of an interaction that may be done&#10;B)the fragment operator name is opt&#10;C)optional fragments have only a single operand, which must contain a guard&#10;D)all of the mentioned

Accepted Answer

Optional fragments in UML sequence diagrams are indeed portions of an interaction that may occur (A), are denoted by the fragment operator name 'opt' (B), and they have a single operand which must contain a guard condition to indicate the circumstances under which the interaction occurs (C).

Question 8

Components can be represented by which of the following&#10;A)component symbols&#10;B)stereotypes&#10;C)rectangular boxes&#10;D)component symbols & stereotypes

Accepted Answer

Components in UML (Unified Modeling Language) can be represented by component symbols, which often include a rectangular box with two smaller rectangles protruding from the left side, and stereotypes, which are a way to extend the vocabulary of UML and can be used to classify and mark components.

Question 9

What does a component diagram consists of&#10;A)components, their relationship to the environment&#10;B)packages and dependency&#10;C)internal structure&#10;D)internal structure, components & their relationship to the environment

Accepted Answer

Component diagrams consist of components, their relationships to each other and to the environment, and often their internal structure, making option D the correct answer.

Question 10

Which of these are types of nodes used in the deployment diagram&#10;A)device&#10;B)execution environment&#10;C)artifact&#10;D)device & execution environment

Accepted Answer

Device and execution environment nodes are both types of nodes used in deployment diagrams. Device nodes represent physical computing resources, while execution environment nodes represent software computing environments where artifacts are deployed.
