Creational Design Patterns Quiz (v2)

Q1. What is the primary purpose of creational design patterns? To manage communication between objects
To control the creation and instantiation of objects
To define the structure of objects and classes
To handle behavioral interactions between objects

Q2. Which creational design pattern ensures a class has only one instance and provides a global point of access to it? Factory Method
Singleton
Builder
Prototype

Q3. In which creational pattern is an object cloned to create new instances? Abstract Factory
Prototype
Singleton
Builder

Q4. Which pattern is used to create an object step-by-step, separating the construction process from its representation? Factory Method
Singleton
Builder
Abstract Factory

Q5. Which creational pattern defines an interface for creating an object but lets subclasses decide which class to instantiate? Builder
Factory Method
Prototype
Singleton

Q6. In the Abstract Factory pattern, what is the main role of the abstract factory? To ensure a single instance of a class
To clone objects for instantiation
To provide an interface for creating families of related objects
To separate object construction from its use

Q7. Which pattern would you use to create different configurations of a complex object, such as a car with varying engines and wheels? Singleton
Builder
Factory Method
Prototype

Q8. In the Prototype pattern, what is a key challenge when implementing deep copying of objects? Ensuring thread safety for the prototype
Handling circular references in the object graph
Preventing multiple instances of the prototype
Defining an interface for object creation

Q9. How does the Abstract Factory pattern differ from the Factory Method pattern in terms of scope and flexibility? Abstract Factory creates single objects, while Factory Method creates families of objects
Factory Method is more flexible as it allows runtime changes to the factory
Abstract Factory focuses on creating families of related objects, while Factory Method focuses on a single object type
Factory Method requires concrete factories, while Abstract Factory does not

Q10. In the context of the Builder pattern, what is the role of the Director, and how does it interact with the Builder? The Director defines the interface for object creation, while the Builder implements it
The Director constructs the object by calling the Builder’s methods in a specific order
The Director clones the Builder to create new instances
The Director ensures the Builder creates a single instance of the product
