A. Observer Pattern
B. Command Pattern
C. Mediator Pattern
D. Chain of Responsibility Pattern
Answer: B. Command Pattern
Explanation: The Command Pattern is a behavioral pattern that provides a way to encapsulate a request as an object and allows the request to be queued, logged, and undone. It is often used to decouple the requester of a command from the object that performs the command.
Which design pattern is used to provide a way to respond to events and changes in state?
A. Observer Pattern
B. Mediator Pattern
C. Template Method Pattern
D. State Pattern
Answer: A. Observer Pattern
Explanation: The Observer Pattern is a behavioral pattern that provides a way to respond to events and changes in state. It is often used when you need to notify multiple objects of a change in state without tightly coupling them together.
Which design pattern is used to provide a way to encapsulate the creation of objects without specifying their concrete classes?
A. Abstract Factory Pattern
B. Factory Method Pattern
C. Prototype Pattern
D. Builder Pattern
Answer: B. Factory Method Pattern
Explanation: The Factory Method Pattern is a creational pattern that provides a way to encapsulate the creation of objects without specifying their concrete classes. It is often used when you need to defer the instantiation of an object to a subclass.
Which design pattern is used to provide a way to ensure that a group of operations are performed as a single transaction?
A. Facade Pattern
B. Proxy Pattern
C. Command Pattern
D. Composite Pattern
Answer: C. Command Pattern
Explanation: The Command Pattern is a behavioral pattern that provides a way to ensure that a group of operations are performed as a single transaction. It is often used when you need to ensure that a series of related operations are executed in a consistent manner.
Which design pattern is used to provide a way to define the skeleton of an algorithm and allow its subclasses to redefine certain steps?
A. Template Method Pattern
B. Strategy Pattern
C. State Pattern
D. Visitor Pattern
Answer: A. Template Method Pattern
Explanation: The Template Method Pattern is a behavioral pattern that provides a way to define the skeleton of an algorithm and allow its subclasses to redefine certain steps. It is often used to provide a standard interface for a family of algorithms, while allowing individual implementations to vary.
Which design pattern is used to provide a way to communicate between objects without them having direct dependencies on each other?
A. Mediator Pattern
B. Observer Pattern
C. Chain of Responsibility Pattern
D. Visitor Pattern
Answer: A. Mediator Pattern
Explanation: The Mediator Pattern is a behavioral pattern that provides a way to communicate between objects without them having direct dependencies on each other. It is often used when a system is composed of many objects that need to interact with each other, but you don’t want them to have tight coupling.
Which design pattern is used to provide a way to handle requests by passing them through a chain of objects until one of them handles the request?
A. Chain of Responsibility Pattern
B. Proxy Pattern
C. Decorator Pattern
D. Adapter Pattern
Answer: A. Chain of Responsibility Pattern
Explanation: The Chain of Responsibility Pattern is a behavioral pattern that provides a way to handle requests by passing them through a chain of objects until one of them handles the request. It is often used to provide a flexible way to handle requests without knowing in advance which object will handle them.
