You may need to create an on-demand backup of a database instance, or restore a
backup.
Which two steps are true about performing an on-demand backup?
A.
You must first connect to the instance VM as theROOTuser.
B.
You must disable the scheduled backup configuration.
C.
You must first connect to the instance VM as theoracleuser.
D.
You must executebkup_apiwith thebkup_startoption.
E.
You must executebkup_apiwith thebkup_createoption.
Explanation:
You can use the bkup_api utility to create an on-demand backup of a databasedeployment
hosting a single-instance database or an Oracle Data Guard configuration.

A,D
B,D are coorect. Root access cant be taken.
B,D are correct.
Per the certification student guide:
……………..
To perform an on-demand backup, you can use:
The utility (as described below) bkup_api
1) connect to the database deployment VM as opc user.
2) disable the scheduled backup configuration in crontab
3) run this command:
#/var/opt/oracle/bkup_api/bkup_api bkup_start

A is correct , from documentation see step no (2):

Creating an On-Demand Backup by Using the bkup_api Utility
You can use the bkup_api utility to create an on-demand backup of a database
deployment hosting a single-instance database or an Oracle Data Guard configuration.
1. Connect as the opc user to the compute node. In a Data Guard configuration,
connect to the compute node hosting the primary database.
For detailed instructions, see Connecting to a Compute Node Through Secure
Shell (SSH).
2. Start a root-user command shell:
$ sudo -s
#
3. You can choose to have the backup follow the current retention policy, or you can
choose to create a long-term backup that persists until you delete it:
• To create a backup that follows the current retention policy, enter the
following bkup_api command:
# /var/opt/oracle/bkup_api/bkup_api bkup_start
•
Notice there´s a difference between saying “You must first connect to the instance VM as the ROOT user.” and “Start a root-user command shell”. The first is not possible because you cannot connect with “the root user” at all. Starting a “root-user command shell” would indicate a user like “root” or another that can carry out operations that require root access…
Thanks for the explanation , so it would be B , D
