Suggested Answer: D 🗳️
Remote Journaling is a technology to facilitate sending copies of the journal of transaction entries from a production system to a secondary system in realtime.
The remote nature of such a connection is predicated upon having local journaling already established. Local journaling on the production side allows each change that ensues for a journal-eligible object e.g., database physical file, SQL table, data area, data queue, byte stream file residing within the IFS) to be recorded and logged. Its these local images that flow to the remote system. Once there, the journal entries serve a variety of purposes, from feeding a high availability software replay program or data warehouse to offering an offline, realtime vault of the most recent database changes.
