Q32. You have a production Oracle 12c database running on a host.
You want toinstall and create databases across multiple new machines that do not have any Oracle database software installed. You also want the new databases to have the same directory structure and components as your existing 12c database.
The steps in random order:
1.Create directory structures similar to the production database on all new machines.
2.Create a response file for Oracle Universal Installer (OUI) with the same configurations as the production database.
3.Create a database clone template for the database.
4.Run the Database Configuration Assistant (DBCA) to create the database.
5.Run OUI in graphical mode on each machine.
6.Run OUI in silent mode using the OUI response file.
Identify the required steps in the correct sequence to achieve the requirementwith minimal human intervention.
