单选题You are working as a Database Administrator. Despite having a password in the data dictionary as change_on_install, you always log on to the database MYNEWDB using operating system authentication. Your organization is planning to recruit two junior-level DBAs.

To allow the new DBAs to perform the administrative tasks, you create a password file on the database server using the following command: ORAPWD file=d:/oracle/ora9i/orapwU01 password=admin entries=4 After creating the password file, you remove the operating system authentication and change the value of the REMOTE_LOGIN_PASSWORDFILE parameter to EXCLUSIVE.
