You want to create a file watcher and an event-based job for detecting the arrival of files on the local server
from various locations. To achieve this, you enable the raising of file arrival events from remote systems.
Which two conditions must be satisfied to receive file arrival events from a remote system?
A.
The remote system must have a running Oracle Database instance and a scheduler agent installed.
B.
The initialization parameter REMOTE_OS_AUTHENT must be set to TRUE on your database.
C.
The local database must be set up to run remote external jobs.
D.
The remote system’s scheduler agent must be registered with your database.
E.
Database links to remote databases must be created.

A, D
Remote systems must be running the Scheduler agent, and the agent must be registered with the database–https://docs.oracle.com/cd/E18283_01/server.112/e17120/scheduse005.htm
I would suggest C and D because:
– You raised the correct point which is “Remote systems must be running the
Scheduler agent, and the agent must be registered with the database.” So this
statement confirmed option D.
– The remote system does not require a running Oracle Database instance to
generate file arrival events. This eliminated option A.
– To enable the raising of file arrival events at remote systems:
1. Set up the local database to run remote external jobs. This confirmed C.
2. Install, configure, register, and start the Scheduler agent on the first
remote system.
