The consistency level determines the number of replicas queried for the read or write request. The consistency doesn't specify what the replication factor should be defined on the keyspace being queried. This is explained in some depth in How consistent read and write operations are handled in Cassandra.
Independent of the consistency level you configure for read and write requests, we recommend configuring three replicas in each data centre for high availability. With three replicas in one data centre, your application can tolerate a node outage when using a strong consistency of
