NEW QUESTION 1
Examine the commands executed in the root container of your multitenant container database (CDB) that has multiple pluggable databases (PDBs):
SQL> CREATE USER c##a_admin IDENTIFIED BY orcl123; SQL> CREATE ROLE c##role1 CONTAINER=ALL;
SQL> GRANT CREATE VIEW TO C##roleI CONTAINER=ALL;
SQL> GRANT c##role1 TO c##a_admin CONTAINER=ALL; SQL> REVOKE c##role1 FROM c##a_admin;
What is the result of the revoke command?
- A. It executes successfully and the c##role1 role is revoked from the c##a_admin user only in the root container.
- B. It fails and reports an error because the container=all clause is not used.
- C. It executes successfully and the c##rocl1 role is revoked from the c##a_admin user in the root database and all the PDBs.
- D. It fails and reports an error because the comtainer=current clause is not use
Explanation: SQL> REVOKE c##role1 FROM c##a_admin; REVOKE c##role1 FROM c##a_admin * ERROR at line 1: ORA - 01951: ROLE ‘C##ROLE1’ not granted to ‘C##A_ADMIN’ SQL> REVOKE c##role1 FROM
c##a_admin CONTAINER=ALL; Revoke succeeded. SQL> This CREATE USER c##a_admin IDENTIFIED BY orcl123; will create common user event container is not specified.
NEW QUESTION 2
You notice a performance change in your production Oracle 12c database. You want to know which change caused this performance difference.
Which method or feature should you use?
- A. Compare Period ADDM report
- B. AWR Compare Period report
- C. Active Session History (ASH) report
- D. taking a new snapshot and comparing it with a preserved snapshot
Explanation: Comparing Current System Performance to a Baseline Period You may have noticed a performance change on a production system and would like to know why, or you may have implemented a change to a production system and want to know the effect of the change, such as increased concurrency waits. The Compare Period ADDM compares the performance of the database server in two time periods, and returns a report describing the performance changes and the root origin of the changes.
The Advisor can analyze any Oracle RDBMS version 10.2.0.4 or later monitored by Cloud Control. The following procedure explains how to initiate a report from the Compare Period ADDM.
NEW QUESTION 3
Which three statements are true regarding the use of the Database Migration Assistant for Unicode (DMU)?
- A. A DBA can check specific tables with the DMU
- B. The database to be migrated must be opened read-only.
- C. The release of the database to be converted can be any release since 22.214.171.124.
- D. The DMU can report columns that are too long in the converted characterset
- E. The DMU can report columns that are not represented in the converted characterset
Explanation: A: In certain situations, you may want to exclude selected columns or tables from scanning or conversion steps of the migration process.
D: Exceed column limit
The cell data will not fit into a column after conversion. E: Need conversion
The cell data needs to be converted, because its binary representation in the target character set is different than the representation in the current character set, but neither length limit issues nor invalid representation issues have been found.
NEW QUESTION 4

- C. Each PDB can have its own default temporary tablespace.
- D. The default permanent tablespace for a PDB can be changed only by a local user with the required permissions.
- E. The amount of space that each PDB can use in a shared temporary tablespace must be set at the CDB level.

NEW QUESTION 7
Examine the RMAN commands executed in your database: RMAN>CONFIGURE DEFAULT DEVICE TYPE TO disk;

Explanation: C: RMAN backup sets automatically use unused block compression. http://docs.oracle.com/cd/B28359_01/backup.111/b28273/rcmsynta007.htm#i1015382
D: If CONFIGURE CONTROLFILE AUTOBACKUP is ON (by default it is OFF), then RMAN automatically backs up the control file and server parameter file after every backup and after database structural
changes. http://docs.oracle.com/cd/B19306_01/backup.102/b14192/bkup003.htm#i1009642 Not E: spfile is also backed up.

NEW QUESTION 16
You issue commands in SQL*Plus as the Oracle owner, to enable multithreading for your UNIX-based Oracle 12c database:
ALTER SYSTEMSETTHREADED EXECUTION= TRUESCOPE=SPFILE; SHUTDOWNIMMEDIATE
You then restart the instance and get an error: STARTUP
Why does the startup command return the error shown?
- A. because the threaded architecture requires exiting from sql*pIus and reconnecting with sql*PIus / as sysdba before issuing a startup command
- B. because the threaded architecture requires issuing a new connect / as sysdba from within sql*pIus before issuing a startup command
- C. because the threaded architecture requires authentication using a password file before issuing a startup command
- D. because the threaded architecture requires connecting to the instance via a listener before issuing a startup command
- E. because the threaded architecture requires restarting the listener before issuing a startup command
Explanation: The first pitfall is, when you try to configure your database for such use. You need a connection which is authenticated trough the password file. Otherwise you will get are error similar to this. https://petesdbablog.wordpress.com/2013/07/09/12c-new-feature-multi-process-multi-threadedoracle/
