QUESTION NO: 1
You executed the following command to perform a backup of the USERS tablespace:
SQL> ALTER TABLESPACE users BEGIN BACKUP;
ALTER TABLESPACE users BEGIN BACKUP
* ERROR at line 1:
ORA-01123: cannot start online backup; media recovery not enabled
What could be the reason for this error?
A. The MTTR Advisor is disabled.
B. The database is in NOARCHIVELOG mode.
C. The tablespace is already in backup mode.
D. The Flash Recovery Area is not configured.
Answer: B

QUESTION NO: 2
You configured the Flash Recovery Area (FRA) for your database. The database instance is running in ARCHIVELOG mode. The default location for the archived redo log files is the Flash
Recovery Area. Which two files are removed automatically if the space is required in the FRA as per the retention policy? (Choose two.)
A. Flashback log files
B. Backups that have become obsolete
C. User managed backups of the data files and control files
D. Archived redo log files that have multiple copies in a different archive location and not backed up
Answer: A,B
Explanation:
Configuring the Flash Recovery Area
Flash recovery area:
* Strongly recommended for simplified backup storage management
* Space on disk (separate from working database files)
* Location specified by the DB_RECOVERY_FILE_DEST parameter
* Size specified by DB_RECOVERY_FILE_DEST parameter
* Large enough for backups, archived logs, flashback logs, mirrored control files, and mirrored redo logs
* Automatically managed according to your retention policy
Configuring the flash recovery area means determining location, size, and retention policy.
Configuring the Flash Recovery Area
The flash recovery area is a space that is set aside on the disk to contain archived logs, backups, flashback logs, mirrored control files, and mirrored redo logs. A flash recovery area simplifies backup storage management and is strongly recommended. You should place the flash recovery area on a disk that is separate from die working set of database files. Otherwise, the disk becomes a single point of failure for your database.
The amount of disk space to allocate for the flash recovery area depends on the size and activity levels of your database. As a general rule, the larger the flash recovery area, the more useful it is.
Ideally, the flash recovery area should be large enough for copies of your data and control files and for flashback, online redo, and archived logs needed to recover the database with the backups kept based on the retention policy. (In short, the flash recovery area should be at least twice the size of the database so that it can hold one backup and several archived logs.) Space management in the flash recovery area is governed by a backup retention policy. A retention policy determines when files are obsolete, winch means that they are no longer needed to meet your data recovery objectives. The Oracle database automatically manages this storage by deleting files that are no longer needed.

QUESTION NO: 3
The HR user creates a stand-alone procedure as follows and grants the EXECUTE privilege on the procedure to many database users:
CREATE OR REPLACE PROCEDURE create_dept ( v_deptno NUMBER, v_dname
VARCHAR2, v_mgr NUMBER, v_loc NUMBER)
BEGIN
INSERT INTO hr.departments VALUES (v_deptno, v_dname, v_mgr, v_loc);
END;
The users having permission to execute the procedure are able to insert records into the
DEPARTMENTS table even though they do not have the INSERT privilege on the table.
You want only those users who have privileges on the DEPARTMENTS table to be able to execute the procedure successfully.
What would you suggest to the PL/SQL developers to achieve this?
A. Create the procedure with definer's right.
B. Create the procedure with invoker's right.
C. Grant the EXECUTE privilege with GRANT OPTION on the procedure to selected users.
D. Create the procedure as part of a PL/SQL package and grant the EXECUTE privilege on the package to selected users.
Answer: B

QUESTION NO: 4
Which two statements are true about checkpointing? (Choose two.)
A. The checkpoint frequency decreases with the smaller redo log file size.
B. It ensures that all committed data is written to the data files during normal shutdown.
C. The frequent full checkpoint in a database can cause the overall degradation of the database performance.
D. It prompts the Checkpoint (CKPT) process to write data to the data files and redo information to the online redo log files.
Answer: B,C
Explanation:
Checkpoint Process (CKPT)
A checkpoint is a data structure that defines a system change number (SCN) in the redo thread of a database. Checkpoints are recorded in the control file and in each data file header. They are a crucia element of recovery.
When a checkpoint occurs, Oracle Database must update the headers of all data files to record the details of the checkpoint. This is done by the CKPT process. The CKPT process does not write blocks to disk; DBWw always performs that work. The SCNs recorded in the file headers guarantee that all changes made to database blocks prior to that SCN have been written to disk.
The statistic DDWR checkpoints displayed by the SYSTEM_STATISTICS monitor in Oracle Enterprise
Manager indicate the number of checkpoint requests that have completed.

QUESTION NO: 5

B. setting the ORACLE_BASE environment variable to an existing directory
C. creating the oper and asmdba operating system groups
D. creating the Oracle Inventory and OSDBA groups in the operating system
E. setting the ORACLE_SID environment variable
