A monitoring system for a Hyperledger Fabric network shows that the 'peer_committer_commit_time' metric is increasing over time, while the 'peer_committer_block_processing_time' is stable. The network's transaction throughput is also declining. What is the most likely cause?

The peer's disk is becoming full, causing slower writes.

The peer's network connection is slow.

The peer's CPU is under heavy load.

The peer's state database is fragmented.

In a blockchain network, what is the role of a node's identity (e.g., a public key or node ID)?

To encrypt the node's log files

To uniquely identify the node and enable secure communication

To store the node's transaction history

To determine the node's geographic location

A consortium running a Hyperledger Fabric network needs to add a new organization. The network uses a channel with a policy requiring endorsement from a majority of organizations. What is the correct sequence of operations?

Update the channel configuration to add the new organization, then have the new organization join the channel.

Create a new channel with the new organization and migrate all existing data.

Have the new organization join the channel first, then update the channel configuration.

Update the peer's core.yaml to include the new organization's MSP, then restart the peer.
