## Question

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

## Correct Answer

_See scenario._

## 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.
