Ans : A,C,E
Exp : Virtual nodes are the nodes created using the same physical node. Let’s assume in your Cassandra cluster there are 3 physical nodes. You can divide each physical node as 4 virtual nodes. Hence, there are in total in cluster total 12 virtual nodes. And token can be divided among these 12 nodes, instead of 3 nodes. And also, token may not be continuous across all vnodes of a single node. Hence, data or load can be distributed across 12 vnodes.
