iSAQB Certified Professional for Software Architecture – Foundation Level (CPSA-F) — Question 18

What are known patterns for the adaptation of interfaces? (Choose two.)

Answer options

• A. Bridge
• B. Tower
• C. Observer
• D. Faֳ§ade
• E. Wall

Correct answer: A, C

Explanation

The Bridge pattern allows for decoupling an abstraction from its implementation, which is essential in adapting interfaces. The Observer pattern enables a subject to notify multiple observers about state changes, making it another valid adaptation method. The other options, Tower, Faֳ§ade, and Wall, do not specifically relate to interface adaptation.
