A Fabric network is using the new lifecycle. A chaincode package has been installed on all peers, and the chaincode definition has been approved by the required organizations. What is the next step to make the chaincode usable on the channel?

Instantiate the chaincode on each peer.

Update the channel configuration to enable the chaincode.

Commit the chaincode definition to the channel.

Restart the peer to load the chaincode.

What is the purpose of auditing chaincode transactions in a Hyperledger Fabric network?

To improve the performance of the chaincode

To automatically fix bugs in the chaincode

To ensure compliance and traceability of all state changes

To reduce the number of peers required for consensus

A blockchain operations team is responsible for maintaining a chaincode that has been in production for several months. They need to ensure that any changes to the chaincode are auditable and that the chaincode is running the expected version. Which practice is most important?

Store the chaincode version in the world state and update it on every invocation.

Use the chaincode's GetHistoryForKey function to track changes to the chaincode code.

Use version control for the chaincode source code and tag each release with a version number.

Use the peer's logging to record every chaincode invocation and its version.

What is the purpose of using the 'cid' (Client Identity) library in Hyperledger Fabric chaincode?

To encrypt the chaincode's state data

To create digital signatures for transactions

To manage the chaincode's lifecycle events

To extract the client's ID, MSP ID, and attributes for authorization decisions

What is a key operational practice for maintaining Hyperledger Fabric chaincode?

Deleting old chaincode versions to free up storage

Regularly reviewing chaincode logs and monitoring peer metrics

Modifying chaincode code directly on the peer to fix bugs

Changing the endorsement policy without notifying other organizations
