You have upgraded your application to implement new features that are production ready and you want to export the live database prior to publishing the new version of the application.
What should be the status of the application?
- A. Obsolete
- B. Pending Push Request
- C. Live
- D. Live Locked
Answer: D
Explanation:
https://docs.oracle.com/en/cloud/paas/app-builder-cloud/csapb/staging-and-publishing-application.html#GUID-4FAD8622-4A32-46EC-92FE-074E557580CA he live application is visible to users according to the Login Security settings for the application.
Each time that you are ready to publish a new version of your application you should lock the live version of your application until the new version is published. This prevents any changes being made to the database that could be lost during the process. While the application is locked you can import the live data into the staging database, if necessary. You can unlock the application after the new version is published.
You cannot make changes to a version of an application after it is published and live. To make additional changes to the application you need to create a new version.
