Show Suggested Answer

Suggested Answer: A

In Hyperledger Fabric, a range query with a start and end key is a type of query that searches for all ledger entries whose keys fall within the specified range defined by the startKey and endKey. This is used, for example, to retrieve a subset of assets from the ledger based on their key values, effectively iterating over a specified range .

Wait, is there an option for 'All of the above'? I'm just kidding, B) Invoke is the clear winner.

A) Evaluate? Really? That's for querying the ledger, not modifying it. B) Invoke is definitely the way to go here.

D) Submit sounds like it could be the answer, but that's usually used for submitting transactions, not directly updating the ledger. I'm going with B) Invoke.

I was considering C) Update, but I guess that's more for modifying existing data rather than invoking a contract function. B) Invoke makes more sense.

I'm not sure, but I think it could also be D) Submit, as it sounds like it could be used to submit changes to the ledger.

Hmm, I think B) Invoke is the correct answer here. The Fabric Gateway client API allows you to invoke smart contract functions to update the ledger state.
