Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Common users can only be created in the root container.
Why this is correct
Common users must be created in CDB$ROOT to be visible across PDBs.
- ✗
Local users are automatically created in all PDBs by default.
Why it's wrong here
Local users exist only within the PDB where they are created.
- ✗
Common users can grant local roles to other common users.
Why it's wrong here
Common users handle common roles; local roles are specific to PDBs.

Common users must have names prefixed with C## or c##.
Why this is correct
The common user naming convention is a strict requirement unless specified otherwise by the O7_DICTIONARY_ACCESSIBILITY parameter.
- ✗
