A manufacturing company is deploying Hyperledger Fabric for a supply-chain tracking system with 15 peer nodes across three organizations. The network must continue to operate if one organization's node goes offline, and transaction ordering must be deterministic. The team is evaluating Raft and Kafka-based ordering services. Which consideration should drive the decision?

Kafka is the only ordering service that supports deterministic transaction ordering in Hyperledger Fabric

Raft provides a crash-fault-tolerant ordering service that is easier to manage because it does not require an external message broker like Kafka

Raft requires a majority of nodes to be online, which means the network will halt if one organization's node is offline

Kafka provides stronger crash fault tolerance than Raft because it uses a distributed log that can survive multiple simultaneous node failures

A global supply chain consortium has participants using Hyperledger Fabric and others using R3 Corda. They need to exchange shipment status data across both platforms. What is the most practical approach?

Create a sidechain for each platform and connect them

Implement a cross-chain gateway or use a common interoperability standard

Use a centralized database to aggregate data from both platforms

Force all participants to migrate to a single platform
