CLEAN : Israeli police at site where Palestinian was killed by army in West Bank

In what scenario is the Facade pattern most useful?

• When there is only one subsystem

• When a system is already simple

• When a system has multiple complex subsystems

• When no interface is needed

Which of the following is an example of the Facade pattern in use?

• Multiple buttons for each machine component

• Direct access to machine internals

• A single button to start a complex machine

• No interface for machine operation

What is the primary purpose of the Facade pattern?

• To add complexity to a system

• To provide a simplified interface to a complex system

• To replace all existing interfaces

• To increase the number of interfaces

How does the Facade pattern help in managing complex systems?

• By adding more layers of abstraction

• By removing all interfaces

• By hiding the complexity behind a single interface

• By exposing all internal components

Which of the following is a benefit of using the Facade pattern?

• Simplified client interaction

• Direct access to all subsystems

• More interfaces to manage

• Increased system complexity
