최신 Oracle Database 19c 1Z0-083 무료샘플문제 (Q235-Q240):

질문 # 235
Which two are true about common objects? (Choose two.)

A. They can be extended data-linked in CDB$ROOT.
B. They can be only metadata-linked in an application container.
C. They can exist in CDB$ROOT and an application root.
D. They can be created only in CDB$ROOT.
E. They can exist in user-defined schemas only in application containers.
F. They can be created only in an application root.

정답：C,F

설명：
A common object is defined in either the CDB root or an application root, and can be referenced using metadata links or object links. A local object is every object that is not a common object.
Database-supplied common objects are defined in CDB$ROOT and cannot be changed. Oracle Database does not support creation of common objects in CDB$ROOT.
You can create most schema objects - such as tables, views, PL/SQL and Java program units, sequences, and so on-as common objects in an application root. If the object exists in an application root, then it is called an application common object.
A local user can own a common object. Also, a common user can own a local object, but only when the object is not data-linked or metadata-linked, and is also neither a metadata link nor a data link.

질문 # 236
Choose two. Which two are true about backup set compression using RMAN default compression?

A. Compression can be done only for locally managed tablespaces.
B. Compressed backups cannot have a section size defined.
C. Unused blocks below the high water mark are backed up.
D. Compressed backups can be written only to media.
E. Binary compression adds CPU overhead to backup operations.

정답：A,E

질문 # 237
How do you configure a CDB for local undo mode?

A. Open the CDB instance in restricted mode.
In cdb$root, execute alter database local undo on.
create an undo tablespace in each PDB, and hen restart the CDB instance
B. Open the CDB instance in upgrade mode.
In cdb$root, execute alter database local undo on, and then restart the CDB instance.
C. Open the CDB instance in upgrade mode.
In each PDB, execute alter database local undo on, create an undo tablespace, and hen restart the CDB instance.
D. Open the CDB in read-only mode.
In cdb$root, ex cute alter database local undo on, and then change the CDB to read/write mode.
E. Open the CDB instance in restricted mode.
In cdb$root, drop the undo tablespace.

질문 # 238
Which two are true about Oracle instance recovery? (Choose two.)

A. Recovery reads redo until the end of the redo thread, and then opens the database. SMON then rolls back any dead transactions.
B. Recovery begins from the last checkpoint position that was recorded in the control file by the checkpoint process (CKPT).
C. Recovery begins from the last checkpoint position that was calculated by the Database Writer before instance failure.
D. Recovery reads redo until the end of the redo thread. SMON rolls back any dead transactions, and then the datanase is opened.
E. Recovery begins from the beginning of the CURRENT redo log group.
F. Recovery begins from the start of any ACTIVE redo log group or the start of the CURRENT log group if no other group is ACTIVE.

정답：A,B

설명：
E: Instance recovery is the process of applying records in the online redo log to data files to reconstruct changes made after the most recent checkpoint. Instance recovery occurs automatically when an administrator attempts to open a database that was previously shut down inconsistently.
..
The checkpoint process (CKPT) is responsible for writing checkpoints to the data file headers and control file.
F: Oracle Database can roll back multiple transactions simultaneously as needed. All transactions that were active at the time of failure are marked as terminated. Instead of waiting for the SMON process to roll back terminated transactions, new transactions can roll back individual blocks themselves to obtain the required data.

질문 # 239
A database is configured in ARCHIVE LOG mode. Full RMAN backups are taken and no backup to trace has been taken of the control file. A media failure has occurred. In which two scenarios is complete recovery possible? (Choose two.)

A. after losing the SYSTEM tablespace
B. after losing all copies of the control file
C. when any archived log from, before, or after the most recent backup is corrupt.
D. after losing an archived log from after the most recent backup
E. after losing an archived log from before the most recent backup
