What is a range query with a start and end key?

Show Suggested Answer Hide 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 .

I hope the exam doesn't have any 'out of range' questions. That would be a real bummer.

A) Yup, that's the one. Range queries are the bread and butter of database navigation.

A) seems like the correct answer. I've used range queries to fetch all the data between a start and end key. Handy for fetching data in batches.

I disagree with option C, I believe option A is more accurate as it directly mentions searching for keys within a range.

I think option A makes sense because it specifies searching within a defined range.
