Each peer in the Hyperledger Fabric network hosts a copy of the ledger, which also belongs to what component?

AThe membership services

BThe Ordering node

CThe NoSQL databases

DA member channel

Show Suggested Answer

Suggested Answer: D

In Hyperledger Fabric, each peer in the network hosts a copy of the ledger, which is associated with a member channel. The ledger itself is comprised of a blockchain to store the immutable, sequenced record in blocks, and a state database to maintain the current state of the ledger. There is one ledger per channel, and each peer maintains a copy of the ledger for each channel of which they are a member .

The membership services don't host the ledger, right?

Wait, are we sure about that? Sounds too simple.

I thought it was the NoSQL databases?

I practiced a question similar to this, and I think it was about membership services, but I could be mixing it up.

I feel like the NoSQL databases might be involved, but I don't know if they directly host the ledger.

I remember something about ordering nodes, but I can't recall if they actually host the ledger copies.

I think the ledger is related to the member channel, but I'm not entirely sure if that's the right answer.

Ah, I remember learning about this in class. The ledger is replicated across all the peers, so it must belong to the membership services component. Option A is my answer.

The ledger is a core part of the Hyperledger Fabric network, so it makes sense that it would belong to one of the key components. I'll review my notes on the architecture to decide which option is most likely.

Hmm, I'm a bit confused about the different components in Hyperledger Fabric. I'll need to think this through carefully before selecting an answer.

I'm pretty sure the ledger belongs to the membership services component in Hyperledger Fabric, so I'll go with option A.

Hmm, I'm a little unsure about this one. I know single audits are important, but I can't quite remember the specifics of who is responsible for resolving the findings. I'll have to think this through.

Hmm, I'm not totally sure about this. I know GUI editors can preview pages, but I'm not confident about the specific browser limitations. I'll have to think this through.

I practiced a similar question, and I feel like PNP was one of the answers, but I can't recall the other one.

I'm a little confused by the wording of this question. Is the administrator creating some kind of virtual storage environment, or just allocating raw capacity? I'll need to review my notes on SAN concepts to make sure I understand the distinctions between the answer choices before selecting one.
