  Correct Answer: C

  When developing a Business Architecture, TOGAF provides guidance on how to leverage existing architecture descriptions to build a comprehensive and accurate Baseline Description. Here's a step-by-step explanation:

  Existing Architecture Descriptions:

  Existing architecture descriptions provide valuable insights into the current state of the enterprise's architecture. These descriptions can include documentation of processes, systems, technologies, and organizational structures.

  Baseline Description:

  The Baseline Description represents the current state of the enterprise architecture. It serves as the starting point for developing the Target Architecture and planning the transition from the current state to the future state.

  Using Existing Descriptions:

  Review and Analyze: Existing architecture descriptions should be reviewed and analyzed to understand the current state accurately. This involves identifying all relevant artifacts, documents, and data. Integration into Baseline: The information

  from the existing descriptions should be integrated into the Baseline Description. This ensures that the Baseline accurately reflects the current state, providing a solid foundation for future planning. Gaps and Opportunities: By using existing

  descriptions, architects can identify gaps in the current architecture and opportunities for improvement. This helps in formulating a more effective Target Architecture.

  TOGAF ADM References:

  Phase A: Architecture Vision: This phase involves establishing the architecture vision, which includes defining the scope and approach for the Baseline Description. Phase B: Business Architecture: During this phase, the Baseline Business

  Architecture is developed using existing architecture descriptions as a key input.
