What is the outcome?

• A. It creates a full export of only the used while connected to the root container and PDB1.

5. Create the SALES_APP1and SALES_APP2application PDBs.
6. Sync the SALES_APP1and SALES_APP2application PDBs with the application root.
7. Sync the SALES_APP1and SALES_APP2application PDBs with the application seed.
8. Sync the application seed with the application root.
