The startup Ro is working at has a Cassandra cluster (Ring) with 7 nodes, and the admin set up a new KeySpace named CoralKeySpace. Ro wants to insert configuration data for their mobile application named CoralApp. The admin has told Ro that the default Replication Factor is 3 on this cluster for CoralKeySpace. Ro inserted 40 records in a table of CoralKeySpace. Which of the following apply?
A: Before the insert query, Ro needs to execute a replicate-all command using cqlsh for the session, so that the data can be replicated on 3 nodes.
B: After the insert query, Ro needs to execute a replicate-all command using cqlsh, so that the data can be replicated on 3 nodes.
C: Ro does not need to do anything, replication is taken care of by Cassandra.
