Free Hyperledger Fabric Certified Practitioner Exam HFCP Exam Practice Test

How should private data collection be configured and deployed?

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

Which are the transaction steps that are managed by the Fabric gateway service?

• Finding a nonce for a pre-image of a hash function for mining.
• Collect transactions into a block and eliminating invalid transactions.
• Evaluate, endorse, submit, and get commit status.
• Realizing a distributed verifiable random function for leader election.

What should be taken into account at implementing efficient CouchDB queries from chaincode?

• Using OLAP (Online analytical processing) and Cube functionality of CouchDB is enough to implement efficient queries.
• Using complex indexes for certain columns is enough even if full scan operators like $or, $in and
• $regex are used.
• Using indexes, focusing on simple queries and avoiding full index scans like with operators $or, $in
• and $regex.
• Using advanced relational algebra and SQL query language options of CouchDB is enough to implement efficient queries.

What types of events committed to the ledger can client applications receive using the peer's event service?

• Only block events
• Both chaincode and block events
• Neither chaincode nor block events
• Only chaincode events

An endorsement policy lists what?

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

In a production environment, what peer items require on-going monitoring?

• Only the orderer service since it manages the ordering of transactions.
• Only the chaincode containers since they handle the business logic.
• All peer containers, including their CPU, network, and memory.
• Only the peer nodes that are running chaincode, since they consume most resources.

Which of the following information do signature policies provide when creating a network in Hyperledger Fabric?

• Identity specific users who must sign in order to satisfy a policy. B Number of nodes in the network

• Get log data
• Get metrics
• Set log level
• Do health check

What are the standard possibilities to configure parameters of a component (peer, orderer) in Hyperledger Fabric?

• Local Linux config files and kubernetes configuration in etcd.
• Global configuration database for storing all relevant parameters.
• Yaml config files, environment variables, flags on CLI commands.
• Individual configuration database for each organization.

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

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