Which method can be used to undo the changes using a single command?
A. restore and recover database
B. flashback transaction
C. flashback database
D. flashback table and transaction
E. flashback table
Examine this configuration:
1.
CDB1 is an Oracle container database from an older release.
2.
PDB1, PDB2, PDB3, and PDB4 are pluggable databases in CDB1.
A priority list UpgrdList has these entries: 1, pdb2 2, pdb1, pdb3
You execute this command: $ /u01/app/oracle/product/18.1.0/ db_1/rdbms/admin/dbupgrade -L UpgrdList
In which order will the upgrade occur?
A. CDB$ROOT, PDB$SEED, PDB2, PDB1, PDB3, and PDB4
