What allows users to update channels, or invoke new Smart Contracts?

Show Suggested Answer Hide Answer
Suggested Answer: C

CouchDB seems like it could be relevant, but I don't remember it being directly tied to invoking new Smart Contracts.

Endorsement policies sound familiar, but I thought they were more about transaction validation rather than updating channels.

I feel like private data collections could be the answer, but I can't recall the specifics about how they relate to updating channels.

I think it might be the peer CLI, but I'm not entirely sure. I remember it being mentioned in a similar practice question.

I think the key here is understanding the different components of Hyperledger Fabric and how they interact. The peer CLI is definitely the tool for managing the network, so I'm leaning towards that as the answer.

The private data collections feature seems like it could be relevant here, since that's how you can restrict access to certain smart contract functions. But I'm not totally sure if that's the right answer.

I'm a bit confused on this one. Is it the endorsement policies that control who can make changes to the network? Or is that a different part of the Hyperledger Fabric architecture?

I'm pretty sure it's the peer CLI that allows users to update channels and invoke new smart contracts. That's the tool we use for those kinds of admin tasks, right?

I'm confident that option D is the correct answer. Exploratory testing is crucial when you don't have a full understanding of the requirements.

Okay, I've got this. The key is to focus on the Layer 2 aspect of the question. DSCP, PREC, and ToS are Layer 3 fields, so they're not relevant here. Dot1p and Q-in-Q are Layer 2 specific, so those are the ones I'll select.

I'm not sure, but I think it could also be D) Endorsement policies, as they determine who can update the blockchain.
