Datastax Cassandra Administrator Certification Questions and Answer (Pratice Questions and Dumps)

Question-: In which keyspace you user credentials are saved?
A. Default keyspace
B. Admin Keyspace
C. system_auth keyspace
D. user_auth keyspace
E. all_user_auth keyspace


Answer: If you are setting up users and their roles and don’t use any other third party tool then all the credentials are stored in a table in a Key space : system_auth. We have to make sure this table is always consistent, because it would be referred by any node in the Cassandra by the user, who is login in. This is just authentication setup.
