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 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.
