Multiple choice technology architecture

Key concept for using Facade pattern:

  1. Adapter pattern is used to access facades

  2. The Adapter pattern adds an indirection object for low coupling

  3. The Façade pattern hides the complexity of a subsystem from a client

  4. None of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The Facade pattern provides a simplified interface to a complex subsystem, hiding its complexity from clients. This reduces coupling and makes the subsystem easier to use. Option C correctly states this purpose. Options A and B incorrectly reference the Adapter pattern.
