  1. Under the default Fabric 2.x lifecycle endorsement policy, how many channel organizations must approve a chaincode definition before it can be committed?

    Answer: A majority of organizations on the channel

    The default LifecycleEndorsement policy is MAJORITY of channel organizations.

  2. Which tool turns a configtx.yaml profile into a genesis block or channel creation artifact?

  3. Why is cryptogen not recommended for a production Fabric network?

    Answer: It produces static keys and certificates with no enrollment, revocation or renewal lifecycle

    cryptogen is a development utility; production networks should use Fabric CA or an enterprise CA for managed identities.

  4. Which consensus option is the recommended ordering service for new production Fabric 2.x networks?

    Answer: Raft

    Raft is the crash-fault-tolerant ordering service recommended since 2.x, with Solo and Kafka deprecated or removed.

  5. A Raft ordering service has 5 nodes. How many node failures can it tolerate while still ordering transactions?

    Answer: 2

    Raft needs a quorum of floor(n/2)+1 = 3 nodes, so up to 2 can fail.

  6. A solution needs rich queries on JSON values in world state. Which state database should be planned for the peers?

    Answer: CouchDB

    CouchDB supports JSON content queries, while LevelDB supports only key and key-range queries.

  7. Which Hyperledger project provides an automation framework for deploying production-grade DLT networks, including Fabric, on Kubernetes?
