Which subcommand adds a peer to a channel in Hyperledger Fabric?

Apeer channel fetch

Bpeer channel creace

Cpeer channel updace

Dpeer channel join

Show Suggested Answer

Suggested Answer: D

In Hyperledger Fabric, the correct subcommand to add a peer to a channel is peer channel join. This command is used by a peer node to join an existing channel. The command requires a block to be specified which typically is the genesis block of the channel, allowing the peer to synchronize with the channel's ledger from the beginning. Other commands like peer channel fetch, peer channel create, and peer channel update serve different purposes. peer channel fetch retrieves blocks from a channel, peer channel create is used to set up a new channel, and peer channel update modifies channel settings. Thus, peer channel join is the specific command used to connect a peer to a channel.

"peer channel create" sounds familiar, but I don't think it's for adding a peer. I might be mixing it up with another command.

I feel like "peer channel fetch" is about retrieving data, not adding peers. But I can't recall the exact command for that.

I remember practicing a question about channel management, and I think "peer channel join" was the right one for adding peers.

I think the command to add a peer is related to joining a channel, but I'm not completely sure if it's "join" or something else.

I feel pretty confident about this one. The "peer channel join" command is used to add a new peer to an existing channel in Hyperledger Fabric. I remember learning about that in the course material, so I'm going to select D.

Okay, let me think this through step-by-step. To add a peer to a channel, we would use the "peer channel" subcommand. The options are fetch, create, update, and join. Adding a peer sounds like it would be the "join" option, so I'll go with D.

Hmm, I'm a bit confused on this one. I know there are different commands related to channels, but I can't quite remember which one is specifically for adding a peer. I'll have to think this through carefully.
