Q56. Your multitenant container database (CDB) contains a pluggable database, HR_PDB. The default permanent tablespace in HR_PDB is USERDATA. The container database (CDB) is open and you connect RMAN.

What happens alter issuing the SHUTDOWN TRANSACTIONAL statement?
A. The shutdown proceeds immediately.
The shutdown proceeds as soon as all transactions in the PDBs are either committed or rolled hack.
B. The shutdown proceeds as soon as all transactions in the CDB are either committed or rolled back.

What are two effects of not using the "ENABLE PLUGGABLE database" clause?

B. The database is treated as a PDB and must be plugged into an existing multitenant container database (CDB).
C. The database is created as a non-CDB and can never be plugged into a CDB.
D. The database is created as a non-CDB but can be plugged into an existing CDB.
E. The database is created as a non-CDB but will become a CDB whenever the first PDB is plugged in.
Q59. You find this query being used in your Oracle 12c database:
Which method a used by the optimizer to limit the rows being returned?
A. A filter is added to the table query dynamically using ROWNUM to limit the rows to 20 percent of the total rows
B. All the rows are returned to the client or middle tier but only the first 20 percent are returned to the screen or the application.
C. A view is created during execution and a filter on the view limits the rows to 20 percent of the total rows.
D. A TOP-N query is created to limit the rows to 20 percent of the total rows
Q60. In your multitenant container database (CDB) containing pluggable database (PDBs), you granted the CREATE TABLE privilege to the common user C # # A_ADMIN in root and all PDBs. You execute the following command from the root container:
SQL > REVOKE create table FROM C # # A_ADMIN;
What is the result?
A. It executes successfully and the CREATE TABLE privilege is revoked from C # # A_ADMIN in root only.
B. It fails and reports an error because the CONTAINER=ALL clause is not used.
C. It excludes successfully and the CREATE TABLE privilege is revoked from C # # A_ADMIN in root and all PDBs.
D. It fails and reports an error because the CONTAINER=CURRENT clause is not used.
