A developer is setting up a local Fabric network for development using Docker Compose. The network will have one peer per organization and a single ordering node. What is the minimal set of configuration files and components needed to bootstrap this network?

A configtx.yaml file and a genesis block, but no docker-compose.yaml.

A docker-compose.yaml file, cryptographic material for each organization, and a configtx.yaml file for channel configuration.

Only a docker-compose.yaml file that defines the peer and orderer containers.

A Kubernetes deployment manifest and a Helm chart for each component.

What is the final step in the Hyperledger Fabric transaction flow?

Peers validate the transaction and commit it to the ledger.

The client receives the endorsement responses.

The ordering service creates a block.

What is chaincode in Hyperledger Fabric?

A configuration file that defines network topology

A certificate used to authenticate peers

A set of rules for ordering transactions

A smart contract that defines the business logic of the network

In Hyperledger Fabric, which consensus mechanism is commonly used by the ordering service in a development environment?

Practical Byzantine Fault Tolerance (PBFT)

What is the primary role of a peer node in Hyperledger Fabric?

To define the business logic of the network

To manage user identities and certificates

To endorse, commit, and store ledger state

To order transactions and create blocks
