NEW QUESTION 10
Which three statements are true about unplugging a pluggable database (PDB)?

D. The unplugged PDB can be plugged into the same multitenant container database (CDB)
E. The unplugged PDB can be plugged into another CDB.
F. The PDB data files are automatically removed from dis

Answer: BDE

Explanation:
B, not A: The PDB must be closed before unplugging it.
D: An unplugged PDB contains data dictionary tables, and some of the columns in these encode information in an endianness-sensitive way. There is no supported way to handle the conversion of such columns automatically. This means, quite simply, that an unplugged PDB cannot be moved across an endianness difference.
E (not F): To explogt the new unplug/plug paradigm for patching the Oracle version most effectively, the source and destination CDBs should share a filesystem so that the PDB’s datafiles can remain in place.

NEW QUESTION 19
Examine the backup requirement for your company:
1) Every Sunday, a backup of all used data file blocks is performed.
2) Every Wednesday and Friday, a backup of all the changed blocks since last Sunday's backup is performed.
3) On all the other days, a backup of only the changed blocks since the last day's backup is performed.
Which backup strategy satisfies the requirements?

A. level 0 backup on Sunday, cumulative incremental backup on Wednesday and Friday, and differential incremental level 1 backup on all the other days
B. level 0 backup on Sunday, differential incremental backup on Wednesday and Friday, and cumulative incremental level 1 backup on all the other days
C. full database backup on Sunday, level 0 backup on Wednesday and Friday, and cumulative incremental level 1 backup on all the other days
D. full database backup on Sunday, level 0 backup on Wednesday and Friday, and differential incremental level 1 backup on all the other days

Answer: A

Explanation:
Multilevel Incremental Backups RMAN can create multilevel incremental backups. Each incremental level is denoted by a value of 0 or 1. A level 0 incremental backup, which is the base for subsequent incremental backups, copies all blocks containing dat
A. You can create a level 0 database backup as
backup sets or image copies. The only difference between a level 0 incremental backup and a full backup is that a full backup is never included in an incremental strategy. Thus, an incremental level 0 backup is a full backup that happens to be the parent of incremental backups whose level is greater than 0. A level 1 incremental backup can be either of the following types: A differential incremental backup, which backs up all blocks changed after the most recent incremental backup at level 1 or 0. A cumulative incremental backup, which backs up all blocks changed after the most recent incremental backup at level 0. Incremental backups are differential by default.

NEW QUESTION 20
Examine the command and its output: SQL> DROP TABLE EMPLOYEE;
SQL> SELECT object_name AS recycle_name, original_name, type FROM recyclebin; RECYCLE_NAMEORIGINAL_NAMETYPE
--------------------------------------------------------------------------------------------------------------
binsgk31sj/3akk5hg3j21kl5j3d==$0EMPLOYEE TABLE
You then successfully execute the command:
SQL> FLASHBACK TABLE "BINSgk31sj/3akk5hg3j21kl5j3d==$0" TO BEFORE DROP;
Which two statements are true?

A. It flashes back the employee table and all the constraints associated with the table.
B. It automatically flashes back all the indexes on the employes table.
C. It automatically flashes back any triggers defined on the table.
D. It flashes back only the structure of the table and not the data.
E. It flashes back the data from the recycle bin and the existing data in the original table is permanently lost.

Answer: BC

Explanation:
A table and all of its dependent objects (indexes, LOB segments, nested tables, triggers, constraints and so on) go into the recycle bin together, when you drop the table. Likewise, when you perform Flashback Drop, the objects are generally all retrieved together. Trigger automatically flashbacked. http://docs.oracle.com/cd/B19306_01/backup.102/b14192/flashptr004.htm#i1020594

Examine the RMAN command:
RMAN> CONFIGURE ENCRYPTION FOR DATABASE ON; RMAN> BACKUP DATABASE PLUS ARCHIVELOG;
Which prerequisite must be met before accomplishing the backup?

A. The password for the encryption must be set up.
B. Oracle wallet for the encryption must be set up.
C. All the tablespaces in the database must be encrypted.

Explanation:

Configuration encryption will used by Transparent encryption. For transparent encryption, you will need to create a wallet, and it must be open. Transparent encryption will then occur automatically
after you have issued the CONFIGURE ENCRYPTION FOR DATABASE ON or CONFIGURE ENCRYPTION FOR TABLESPACE ON command. http://docs.oracle.com/cd/E25054_01/backup.1111/e10642/rcmbckad.htm#CEGEJABH
CONFIGURE ENCRYPTION : You can use this command to persistently configure transparent encryption. You cannot persistently configure dual mode or password mode encryption. SET ENCRYPTION : You can use this command to configure dual mode or password mode encryption at the RMAN session level.
