Which two statements are true for Data Guard environments with multi-tenant databases?

A.DB_UNIQUE_NAME must be specified differently for each pluggable database within a multi-tenant standby database.
B.Each pluggable database within a multi-tenant physical standby database has a minimum of one associated Oracle Net service name.
C.Each pluggable database within a multi-tenant physical standby has one MRP background process running during redo apply.
D.A pluggable database within a multi-tenant standby database can have a different open mode than the container database.
E.A pluggable database within a multi-tenant standby database can have a different database role than the container database.

Explanation

Incorrect Answers: C: in 12c Data Guard is set up at the Container level and not the individual Pluggable database level as the redo log files only belong to the Container database and the individual pluggable databases do not have their own online redo log files. E: The database role is defined at the CDB level, not at the individual container level. Any DDL related to role changes must be executed in the root container because a role is associated with an entire CDB. Individual pluggable databases (PDBs) do not have their own roles.
