Correct Answer: 4
Explanation: virtual nodes allow us to create individual smaller ranges per node, and it breaks up these ranges across the cluster. Now, each single node doesn't have all the data. By default, pre-3.0, it is 256 ranges per node. Now, past 3.0, it's much less, and it's configurable by the user.
