Which three are true about upgrading an application in an application container? (Choose three.)
Which three are true about upgrading an application in an application container? (Choose three.)
When upgrading an application in an application container, an application root clone gets created automatically to ensure availability during the upgrade process. The application name and version number must be specified to accurately manage the upgrade paths. After an application upgrade, the PDBs within the application container are automatically synchronized with the application root clone, ensuring continuity and integration with the new application version.
The correct answer are BCE E as "ALTER PLUGGABLE DATABASE APPLICATION saas_sales_app BEGIN UPGRADE '1.0' to '2.0'" During an application upgrade, the application remains available. To make this availability possible, Oracle Database clones the application root. applications pdbs remain syncronzed with clone application root
bcf After the upgrade, the application root clone remains and continues to support any application PDB that still use the preupgrade version of the application in the root clone. Application PDBs that upgrade are pointed to the upgraded application root. Application PDBs that do not upgrade might continue to use the clone, and application PDBs that are plugged into the application root might also use the same application version as the root clone.

The correct answer is B,E,F C is incorrect because the PDBs remain synchronized with root clone not existing root. The existing root is after upgrade in a new Version. At this stage, the application PDBs are still pointing to the application root clone, and the original application root is at a new version. For example, if the saas_sales_app application is at version 1.0 in the application root, then the upgrade might bring it to version 2.0. The application root clone, however, remains at version 1.0. Optionally, the user synchronizes the application PDBs with the upgraded application root by issuing ALTER PLUGGABLE DATABASE APPLICATION statement with the SYNC clause.

You must use SYNC command. if you don't sync app pdb, app pdb automatically use the cloned app cdb. when you sync an app pdb, it uses existing app cdb. When you perform an app upgrade you must specify application name versionFrom and versionTo
B,C,E correct - assuming C is after sync performed in the PDBs
BCE according to docs
BCE correct
