Predecessor lists because they define ordering

Why do the slides require comparing structural diagrams with interaction diagrams after creating both?
a)
To correct inconsistencies between the structural and interaction models
b)

The interaction diagram
b)
The UI mockup
c)
The programming language type system
d)
The network protocol specification

The database index design
93.
If a class exists in the structural diagram but no objects of that class participate in any interaction diagram, what do the slides suggest?
a)
Remove the class from the structural diagram
b)
Add more attributes to the class until it participates
c)
Convert the class into a boundary class
d)
Force a message to be sent to it to justify its existence
e)
Replace the class with a multi-object symbol
94.
When an object of class A sends a message to an object of class B, what must exist in class B according to the slides?
a)
A public operation corresponding to the message with matching parameter list
b)
A boundary screen definition containing UI widgets
c)
A predecessor list listing all messages sent by A
d)
A derived attribute for each parameter of the message
e)
An association to every entity class in the system
95.
When an object of class A sends a message to an object of class B, what must exist in class A according to the slides?
a)
An operation responsible for sending that message
b)
A public operation with the same name as the receivers operation
c)
A protocol implementation for the receivers device interface
d)
A return message explicitly drawn in the class diagram
e)
A multi-object representing all instances of class B
96.
For messages sent to an agent that is a person, how do the slides interpret the message?
a)
It requests the person to perform an action specified in the user manual
b)
It must trigger a public operation in a person class
c)
It is treated as a lost message because people are outside scope
d)
It must always be asynchronous with an explicit return
e)
It is replaced by an association between boundary and entity classes
97.
For messages sent to an external system, what modeling requirement is stated in the slides?
a)
Represent the external system as a class with appropriate operations that the message activates
b)
Model the external system only as an actor without any operations
c)
Remove external systems from interaction diagrams to reduce clutter
d)
Treat all external system messages as local calls on the sender
e)
Convert external system messages into derived attributes
98.
For messages sent to a GUI interface class, what do the slides say the request is directed to?
a)
Graphical elements such as fields or buttons rather than an operation
b)
A public operation whose name matches the message
c)
A dependency connection stereotyped as <<global>>
d)
A predecessor list that enforces synchronization
e)
A class attribute typed using a specific programming language
99.
According to the slides, private operations correspond to what kind of messages?
a)
Recursive messages sent to the same object, not messages from other objects
b)
Messages sent from boundary objects to control objects
c)
Asynchronous messages delivered through a queue
d)
Lost messages with unidentified receivers
e)
Messages that create new objects
100.
When adding types to attributes, parameters, and return values, which type categories are listed in the slides?
a)
Primitive types, user-defined types, and classes
b)
Only primitive types
c)
Only programming-language built-in types
d)
Only UI widget types
e)
Only database column types
101.
Why do the slides recommend avoiding programming-language-specific type names at this stage?
a)
Using general type names is more flexible before committing to a specific language
b)
Language-specific types are not allowed in UML diagrams
c)
General type names force synchronous messaging
d)
Language-specific types prevent entity classes from being discovered
e)
General type names eliminate the need for control classes
102.
If understanding between two objects is inherent and long-term, what kind of relationship does the slides say this expresses between their classes?
a)
An association
b)
A dependency
c)
A predecessor constraint
d)
A focus-of-control nesting
e)
A found message
103.
If understanding between two objects is newly provided via parameter passing or a return value, what relationship does the slides say this expresses?
a)
A dependency from A to B
b)
A two-way association between A and B
c)
A multi-object aggregation
d)
A self connection on A
e)
A derived attribute on B
