Answer : B

In Hyperledger Fabric, block events are provided by peers. Whenever a block is committed to a peer's ledger, that peer generates a corresponding event. These events can include the full block content or a summary of the transactions within the block, allowing applications to register and receive notifications about these events. This setup is crucial for applications that need to respond to changes recorded on the blockchain in real-time .

Answer : B

The Fabric Gateway client APIs in Hyperledger Fabric streamline the transaction submission process by combining endorsement, submission, and commitment into a single function. This allows client applications to efficiently manage transaction submissions with a single line of code, specifically through the SubmitTransaction() function. This consolidation simplifies the interaction model for applications, enabling a focus on business logic rather than the underlying blockchain infrastructure details .

Answer : B

Hyperledger Fabric allows different versions of the platform to coexist and interoperate on the same network through the use of channel capabilities. Channel capabilities enable organizations running different versions of Fabric binaries to participate on the same channel. These capabilities govern the features that are used by peer nodes and set the minimum version of the Fabric binaries that can be run by peers joined to the channel. This allows for heterogeneous network environments where different nodes might be running different versions of Fabric software .

Answer : A

Hyperledger Fabric supports pluggable consensus mechanisms that allow the system to be tailored to specific trust assumptions of a deployment. The platform allows for the implementation of various consensus protocols, including Crash Fault Tolerant (CFT) and Byzantine Fault Tolerant (BFT). However, the specific support for only CFT or BFT would depend on the implementation choice within the context of the deployment's trust model. Fabric's modular architecture supports well-established consensus protocols for both CFT and BFT .

Answer : B

Theidemixgentool is used to create configuration files for the Identity Mixer based MSP (Membership Service Provider) in Hyperledger Fabric.When configuring membership, theidemixgentool creates three directories:/ca/,/msp/, and/user/1. The/ca/directory contains the issuer secret key, issuer public key, and revocation key, which should only be present for a Certificate Authority (CA). The/msp/directory contains the issuer public key and revocation public key, which are required to set up an MSP that verifies Identity Mixer signatures.The/user/directory specifies a default signer configuration1. Therefore, the correct answer is the user directory, which is created alongside the ca and msp directories by theidemixgentool.
