Curious about Actual Linux Foundation Hyperledger Fabric Practitioner (HFCP) Exam Questions?

Correct : C

In Hyperledger Fabric, the peer CLI (Command Line Interface) tool is used to update channels or invoke new smart contracts. This utility allows users to perform various administrative tasks on the network, such as updating the ledger, changing endorsement policies, and managing chaincode installations and instantiations .

Correct : D

In Hyperledger Fabric, to enable CouchDB as the state database, the stateDatabase configuration option in the core.yaml file must be changed from goleveldb to CouchDB. This change directs the peer to use CouchDB instead of the default LevelDB for storing the world state, which can then be queried using rich queries and provides additional features like indexing.

Correct : B

In Hyperledger Fabric, a unique ID to represent an asset on the ledger is typically generated in the client application before the transaction is submitted to the blockchain. This approach ensures that each asset has a unique identifier, which is crucial for tracking and managing assets throughout their lifecycle on the ledger.

Correct : B

The last step in the Hyperledger Fabric transaction flow is the commitment of the transaction to the ledger and the subsequent notification to the client application1. Once the transaction has been endorsed and ordered, it is committed to the ledger on all peers. After the transaction is committed, the peers asynchronously notify the client application of the success or failure of the transaction.This ensures that the client application is aware of the outcome and can take appropriate actions based on the result of the transaction1

Correct : C

The transaction steps managed by the Fabric gateway service in Hyperledger Fabric are to evaluate, endorse, submit, and obtain the commit status of transactions. This service simplifies the process for clients by handling these critical transaction steps, which facilitates more efficient transaction processing and management within the network .
