Linux Foundation Hyperledger Fabric Certified Practitioner (HFCP) Exam Sample Questions (Q44-Q49):

NEW QUESTION # 44
Regarding peerlifecycle chaincode, which of the following is the incorrect (unsupported) subcommand for query?

  • A. peer lifecycle chaincode querypackaged
  • B. peer lifecycle chaincode queryapproved
  • C. peer lifecycle chaincode queryinstalled
  • D. peer lifecycle chaincode querycommitted

Answer: A

Explanation:
The correct subcommands for querying in the peer lifecycle chaincode
are queryinstalled, queryapproved, checkcommitreadiness, commit, and querycommitted1. The subcommand querypackaged is not a supported subcommand for querying in the peer lifecycle chaincode.


NEW QUESTION # 45
In Hyperledger Fabric, what data structures manage sensitive information between organizations?

  • A. Ordering service
  • B. Endorsement policies
  • C. State database
  • D. Private data collections

Answer: D

Explanation:
In Hyperledger Fabric, "private data collections" are used to manage sensitive information between organizations. This feature allows specified subsets of data to be shared among a defined group of network participants while keeping it hidden from others, thus maintaining confidentiality and privacy across the network. Private data collections enable organizations to transact privately without having to establish a separate channel, significantly reducing the overhead associated with channel management .


NEW QUESTION # 46
What happens if the user submits a transaction with no matching function?

  • A. The unknownTransaction function is called.
  • B. The first transaction function is called.
  • C. The peer will have rejected the transaction.
  • D. Nothing, the transaction is ignored.

Answer: A

Explanation:
In Hyperledger Fabric, if a user submits a transaction with no matching function specified in the smart contract, theunknownTransactionfunction is invoked by default. This function serves as a catch-all method that can be used to handle cases where the transaction type is not recognized, providing a mechanism to manage or log these occurrences effectively .


NEW QUESTION # 47
How should private data collection be configured and deployed?

  • A. Private data collection is configured and deployed with the help of a dedicated REST API that is available on the orderers.
  • B. Private data collection configuration is setup at the core network structure configuration with the components.
  • C. Private data collection is configured at the X5C9 certification generation process of the certificate authorities.
  • D. Private data collection configuration is described in a separate ison file and deployed at chaincode deployment.

Answer: D

Explanation:
In Hyperledger Fabric, private data collections are configured using a separate JSON file that describes the details of the collection, such as the name, policy, and member organizations that have access to it. This configuration file is included during the chaincode deployment process. The collections configuration file defines how private data is managed, including its lifecycle,storage, and dissemination between authorized peers. By configuring private data collections in this manner, organizations ensure that sensitive information is only accessible to specific participants in the network, thus maintaining confidentiality and compliance with data governance standards.


NEW QUESTION # 48
When submitting a transaction, how can a client application send information to be stored only in a private data collection?

  • A. Include it as transient data.
  • B. Encrypt it using the client private key.
  • C. Transfer it using an off-chain data store.
  • D. Send it as a chaincode event.

Answer: A

Explanation:
In Hyperledger Fabric, to send information that should be stored only in a private data collection during a transaction submission, the information must be included as transient data. Transient data is sent along with the transaction proposal but is not recorded on the ledger; instead, it is used within the chaincode for processing and can then be stored in private collections as needed. This method ensures that sensitive information is kept out of the public ledger and is only available to authorized parties as defined in the private data collection configuration. Transient data provides a secure way to handle sensitive or confidential information within the network without exposing it on the shared ledger.
