Certified Blockchain Solutions Architect (CBSA) — Question 43

Which of the following is true concerning Hyperledger Composer?

Answer options

• A. It's a competing blockchain to Hyperledger Fabric in the Hyperledger suite of tools
• B. It's an API layer that sits above Hyperledger Fabric and is required to interact with the Fabric blockchain
• C. It's a toolset and framework for easily developing business networks
• D. It's a consensus-focused replicable state machine framework for blockchain development

Correct answer: C

Explanation

The correct answer is C, as Hyperledger Composer is specifically designed as a toolset and framework to facilitate the creation of business networks. Option A is incorrect because Composer is not a competing blockchain but rather a tool that works with Fabric. Option B is also wrong since Composer is not a necessary API layer for Fabric, and option D mischaracterizes Composer's purpose by focusing on consensus mechanisms.
