Linux Foundation Hyperledger Fabric Certified Practitioner (HFCP) Exam Sample Questions (Q18-Q23):

NEW QUESTION # 18
In Hyperledger Fabric, what is used if end users of the application want to keep their private key secret?
In Hyperledger Fabric, what is used if end users of the application want to keep their private key secret?

  • A. Shared signing
  • B. Offline signing
  • C. Online signing
  • D. No signing is required

Answer: B

Explanation:
In Hyperledger Fabric, if end users of the application want to keep their private key secret and secure, they would use offline signing. Offline signing involves signing transactions on a device or in an environment that is not connected to the network or the internet. This method ensures that the private key used for signing does not get exposed to the network and reduces the risk of compromise. Offline signing is especially important in scenarios where security and privacy are paramount, as it allows users to maintain control over their private keys at all times.


NEW QUESTION # 19
Which arguments must be supplied when a client application uses the Fabric Gateway client API to create a Gateway connection to a Fabric network?

  • A. Client public key and signing implementation
  • B. Client X.509 certificate and private key
  • C. Connection profile and client private key
  • D. connection and client identity

Answer: B

Explanation:
When a client application uses the Fabric Gateway client API to create a Gateway connection to a Hyperledger Fabric network, it must supply the client's X.509 certificate and private key. The X.509 certificate is used to authenticate the client to the network, confirming the client's identity and permissions. The private key is used for signing transactions, which is necessary for the network to validate the integrity and origin of the transactions submitted by the client. This combination ensures that both the identity of the client is verified and that transactions cannot be tampered with without detection.


NEW QUESTION # 20
Where would you generate a unique ID to represent an asset on the ledger?

  • A. In a custom validation plugin
  • B. In a private data collection
  • C. In the smart contract
  • D. In the client application

Answer: D

Explanation:
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.


NEW QUESTION # 21
In Hyperledger Fabric, CouchDB is enabled as the state database by changing the state Database configuration option from goleveldb to what?

  • A. gocouchdb
  • B. goCouch
  • C. CouchDB
  • D. setCouchDB

Answer: C

Explanation:
In Hyperledger Fabric, to enable CouchDB as the state database, thestateDatabaseconfiguration option in the core.yamlfile must be changed fromgoleveldbtoCouchDB. 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.


NEW QUESTION # 22
An endorsement policy lists what?

  • A. The number of organizations involved in a transaction.
  • B. The number of peers needed to endorse a transaction.
  • C. The order in which transactions are executed.
  • D. The identities required for endorsing a transaction.

Answer: D

Explanation:
In Hyperledger Fabric, an endorsement policy specifies which network participants, identified by their digital identities, must endorse a transaction before it can be considered valid. This is crucial for the network's security and integrity, as it controls how transactions are approved andadded to the ledger. Endorsement policies are part of the channel configuration and can be customized to fit the specific needs of a business network. They dictate the necessary endorsements from specific organizations or even particular roles within those organizations, ensuring that only authorized entities can validate transactions. This mechanism supports the collaborative yet secure nature of the enterprise blockchain, where trust is decentralized across different organizations that are part of the network.
