TOGAF 9 Foundation (Level 1) — Question 191

Which of the following statements about TOGAF Building Blocks is true?

Answer options

• A. A good Building Block should not be composed of other Building Blocks
• B. Architecture Building Blocks should be first selected in Phase D
• C. Building Block specifications should be loosely coupled to implementation
• D. Custom developments are known as Architecture Building Blocks

Correct answer: C

Explanation

Option C is correct because Building Block specifications should be designed to allow flexibility in implementation, ensuring they can be adapted to various contexts. Option A is incorrect as Building Blocks can indeed be composed of other Building Blocks to form more complex structures. Option B is wrong because Architecture Building Blocks are typically identified earlier in the process, and Option D is misleading because while custom developments can be recognized as Building Blocks, they are not exclusively categorized as such.
