Choose two.
Examine this configuration:
1-. CDB1 is a container database.
2-. APP1_ROOT is an application container contained in CDB1.
3-. APP1_ROOT$SEED is the application seed contained in APP1_ROOT and
Synchronized with APP1_ROOT.
4-. APP1_PDB1 and APP1_PDB2 are application PDBs contained in APP1_ROOT.
5-. APP1_USER_APP is an application installed in APP1_ROOT at version 1.0.
6-. USER1 is a common user in APP1_ROOT and all its application PDBs created
When version 1.0 of APP1_USER_APP was installed.
You execute these commands:
$ sqlplus sys/oracle@localhost:1521/cdb1 as sysdba
SQL> ALTER SESSION SET CONTAINER=app1_root;
Session altered.
SQL> ALTER PLUGGABLE DATABASE APPLICATION app1_user1_app BEGIN UPGRADE '1.0' TO
'2.0';
Pluggable database altered.
SQL> GRANT CREATE SESSION TO USER1;
Grant succeeded.
SQL> ALTER PLUGGABLE DATABASE APPLICATION app1_user1_app END UPGRADE TO '2.0';
Pluggable database altered
SQL> ALTER SESSION SET CONTAINER=app1_pdb1;
Session altered.
SQL> ALTER PLUGGABLE DATABASE APPLICATION app1_user1_app SYNC;
Pluggable database altered.
Which two are true?
A.USER1 can connect to CDB1. B.USER1 can connect to APP1_ROOT and APP1_PDB1. C.USER1 can connect to APP1_ROOT APP1_ROOT$SEED and APP1_PDB1. D.USER1 is defined in APP1_PDB2. E.USER1 can connect only to APP1_PDB1. F.USER1 can connect only to APP1_ROOT.正确答案BD
