Question 1

Which of the following depicts the interactions among objects during a certain period of time?
A)class diagrams
B)data flow diagrams
C)sequence diagrams
D)collaboration diagrams

Accepted Answer

Sequence diagrams are used to represent the interactions among objects during a certain period of time. They show the sequence of messages exchanged between the objects and the order in which they occur. Class diagrams represent the class structure of a system, data flow diagrams represent the flow of data through a system, and collaboration diagrams focus on the relationships between objects.

Question 2

When an operation calls upon another operation within the same object,this is known as:
A)a recursive join
B)a nested operation
C)self-delegation
D)a nested state

Accepted Answer

This scenario is called self-delegation, where an operation calls upon another operation within the same object. It is a common practice in programming and helps to keep code organized and reduce repetition.

Question 3

A message in which the sender does not have to wait for the recipient to handle the message best describes:
A)synchronous message
B)simple message
C)asynchronous message
D)half-duplex message

Accepted Answer

Asynchronous message refers to a message that the sender can send without waiting for the recipient to handle the message. This means that the sender can continue with their work without being interrupted by waiting for a reply from the recipient.

Question 4

Sequence diagrams represent dynamic models of interactions between objects.

Accepted Answer

Sequence diagrams show the interactions between objects in a system or process, including the order in which messages are sent and received. They are a type of dynamic model used in software engineering and other systems analysis disciplines.

Question 5

In UML,a __________ represents dynamic models of interactions between objects.

Accepted Answer

The answer of In UML,a __________ represents dynamic models of...

Question 6

Sequence diagrams show the static structure of data and the operations that act on the data.

Accepted Answer

Sequence diagrams show the dynamic behavior of a system, illustrating how objects interact with each other and in what sequence to complete a task or process. They do not show the static structure of data.

Question 7

Sequence diagrams can be presented in:
A)instance or generic form
B)logical or physical form
C)sequential or nonsequential form
D)specific or nonspecific form

Accepted Answer

Sequence diagrams can be presented in instance (showing specific instances of objects and their interactions) or generic (showing the interactions between types of objects) form. The other options listed are not valid distinctions for sequence diagrams.

Question 8

On a sequence diagram,the destruction of an object is shown as a:
A)wavy line
B)large X
C)transverse tick mark
D)filled in circle

Accepted Answer

The answer of On a sequence diagram,the destruction of an...

Question 9

On a sequence diagram,a synchronous message is shown as a half arrowhead.

Accepted Answer

The answer of On a sequence diagram,a synchronous message is...

Question 10

A sequence diagram depicts the interactions among objects during a certain period of time.

Accepted Answer

A sequence diagram is a type of UML diagram that illustrates the interactions between objects or parts in a system or application as they occur over time. It shows the sequence of messages or method calls between objects or components, and can be used to visualize the behavior of a system or application as it executes.

Question 11

A message that transfers control from the sender to the recipient without describing the details of the communication best describes:
A)predetermined message
B)implicit message
C)simple message
D)flag

Accepted Answer

The answer of A message that transfers control from the...

Question 12

Sequence is a type of interaction diagrams.

Accepted Answer

Sequence diagrams are a type of interaction diagrams along with communication diagrams (also known as collaboration diagrams).

Question 13

Which of the following shows the time period during which an object performs an operation,either directly or through a call to some subordinate operation?
A)asynchronous message
B)activation
C)critical path
D)simple message

Accepted Answer

Activation is the time period during which an object performs an operation, either directly or through a call to some subordinate operation. Asynchronous message refers to a message that is independent of the sender's execution, while simple message just refers to a basic message passing mechanism. Critical path refers to the longest path in a project network diagram that determines the shortest possible duration of the project.

Question 14

Objects communicate with one another by sending messages.

Accepted Answer

In object-oriented programming, communication between objects is achieved through sending messages. Objects are designed to respond to specific messages or requests sent to them by other objects.

Question 15

Which of the following represent dynamic models of interactions between objects?
A)use cases
B)class diagrams
C)state diagrams
D)sequence diagrams

Accepted Answer

The answer of Which of the following represent dynamic models...

Question 16

A type of message in which the caller has to wait for the receiving object to finish executing the called operation before it can resume execution itself is a(n):
A)synchronous message
B)simple message
C)asynchronous message
D)half-duplex message

Accepted Answer

An asynchronous message is a type of message in which the caller does not have to wait for the receiving object to finish executing the called operation before it can resume execution itself. Therefore, the opposite of an asynchronous message is a synchronous message where the caller has to wait for the receiver to complete the operation before resuming its execution.

Question 17

__________ is a type of interaction diagrams.

Accepted Answer

The answer of __________ is a type of interaction diagrams....

Question 18

A simple message is a message in which the sender does not have to wait for the recipient to handle the message.

Accepted Answer

The answer of A simple message is a message in...

Question 19

Types of interaction diagrams include:
A)state diagrams
B)sequence diagrams
C)data flow diagrams
D)component diagrams

Accepted Answer

Sequence diagrams are used to show the interactions between different objects or components in a system, making them the most appropriate type of interaction diagram for this question. State diagrams are used to show the states that an object can be in and how it transitions between those states. Data flow diagrams are used to show how data moves through a system, and component diagrams are used to show the different components of a system and how they interact.

Question 20

Sequence diagrams represent dynamic models of how objects change their states in response to events.

Accepted Answer

The answer of Sequence diagrams represent dynamic models of how...
