The HR_ROOT application container must support the execution of a query on a table shared by application local PDBs PDB1 and PDB2, and remote PDB PDB3. Which three are true? (Choose three.)
Correct Answer: B,E,F
Database link must be created in master application root (local CDB) referring to replica application root (remote CDB). Option B Proxy PDB must be created in master application root (local CDB) using this database link. Option F Replica application root must exist in remote CDB (created or upgraded using SYNC in local Proxy PDB). Option E With this, we can make a SELECT that will show data from local and remote PDB applications (Query in local master application root using CONTAINERS clause). https://docs.oracle.com/en/database/oracle/oracle-database/18/multi/administering-application- containers-sql-plus.html#GUID-B96087B5-678C-4781-9464-42FC468B1FCC
