NEW QUESTION 1
A redaction policy was added to the SAL column of the SCOTT.EMP table: BEGIN
DBMS_REDACT.ADD_POLICY( OBJECT_SCHEMA => ‘SCOTT’, OBJECT_NAME => ‘EMP’, POLICY_NAME => ‘SCOTT_EMP’, COLUMN_NAME => ‘SAL’,
EXPRESSION => ‘SYS_CONTEXT (‘‘SYS_SESSION_ROLES’’, ‘‘MGR’’) = ‘‘FALSE’’’); END;
/
All users have their default set of system privileges.
For which three situations will data not be redacted? (Choose three.)

A. SCOTT sessions, because he is the owner of the table
B. SCOTT sessions, only if the MGR role is granted to SCOTT
C. SCOTT sessions, only if the MGR role is set in the session

Answer: BCD

NEW QUESTION 2
Your database is running in archivelog mode. Examine the parameters for your database instance: LOG_ARCHIVE_DEST_l ='LOCATION=/disk1/arch MANDATORY'
LOG_ARCHIVE_DEST_2 ='LOCATION=/disk2/arch' LOG_ARCHIVE_DEST_3 ='LOCATIO=/disk3/arch' LOG_ARCHIVE_DEST _4 ='LOCATIONs/disk4/arch' LOG_ARCHIVE _MIN_SUCCEED_DEST = 2
While the database is open, you notice that the destination set by the log_archive_dest_1 parameter is not available. All redo log groups have been used.
What happens at the next log switch?

A. The database instance hangs and the redo log files are not overwritten.
B. The archived redo log files are written to the fast recovery area until the mandatory destination is made available.
C. The database instance is shutdown immediately.
D. The destination set by the log_archive_dest parameter is ignored and the archived redo log files are created in the next two available locations to guarantee archive log success.

Answer: A

Explanation: Made more logfile switch until all redos groups are full. first log switch succeds, second also succeds then next will hang database.

NEW QUESTION 3

Which two statements are true?

A. The memory_max_target parameter is automatically set to 500 MB.
B. The pga_aggregate_target and sga_target parameters are automatically set to zero.
C. The value of the memory_max_target parameter remains zero for the database instance.
D. The lower limits of the pga_aggregate_target and sga_target parameters are set to 90 MB and 270 MB respectively.
E. The instance does not start up because Automatic Memory Management (AMM) is enabled but pga_aggregate_target and sga_target parameters are set to nonzero values.

Answer: AD

NEW QUESTION 7
You create two Resource Manager plans, one for night time workloads, the other for day time.
How would you make the plans switch automatically?

A. Use job classes.
B. Use scheduler windows.
C. Use the mapping rule for the consumer groups.
D. Set the switch_time plan directive for both plans.
E. Use scheduler schedule

Answer: B

Explanation: The resource manager is only activated when a default resource plan is assigned. Only one resource plan can be active at any given time. Resource plan switches can be automated using scheduler windows or performed manually by setting the resource_manager_plan parameter using the alter system command as shown below.

A complete database backup to media is taken for your database every day. Which three actions would you take to improve backup performance?

A. Set the backup_tape_io_slaves parameter to true.
B. Set the dbwr_io_slaves parameter to a nonzero value if synchronous I/O is in use.
C. Configure large pool if not already done.
D. Remove the rate parameter, if specified, in the allocate channel command.
E. Always use RMAN compression for tape backups rather than the compression provided by media manager.
F. Always use synchronous I/O for the databas

Answer: BCD

Explanation: Tuning RMAN Backup Performance: Procedure Many factors can affect backup performance. Often, finding the solution to a slow backup is a process of trial and error. To get the best performance for a backup, follow the suggested steps in this section: Step 1: Remove RATE Parameters from Configured
and Allocated Channels Step 2: If You Use Synchronous Disk I/O, Set DBWR_IO_SLAVES Step 3: If You Fail to Allocate Shared Memory, Set LARGE_POOL_SIZE Step 4: Tune RMAN Tape Streaming Performance Bottlenecks Step 5: Query V$ Views to Identify Bottlenecks https://docs.oracle.com/database/121/BRADV/rcmtunin.htm#BRADV172

NEW QUESTION 10
You plan to use the In-Database Archiving feature of Oracle Database 12c, and store rows that are inactive for over three months, in Hybrid Columnar Compressed (HCC) format.
Which three storage options support the use of HCC?

A. ASM disk groups with ASM disks consisting of Exadata Grid Disks.
B. ASM disk groups with ASM disks consisting of LUNS on any Storage Area Network array
C. ASM disk groups with ASM disks consisting of any zero padded NFS-mounted files
D. Database files stored in ZFS and accessed using conventional NFS mounts.
E. Database files stored in ZFS and accessed using the Oracle Direct NFS feature
F. Database files stored in any file system and accessed using the Oracle Direct NFS feature
G. ASM disk groups with ASM disks consisting of LUNs on Pillar Axiom Storage arrays

Answer: AEG

Explanation: HCC requires the use of Oracle Storage – Exadata (A), Pillar Axiom (G) or Sun ZFS Storage Appliance (ZFSSA).
Note:
* Hybrid Columnar Compression, initially only available on Exadata, has been extended to support Pillar Axiom and Sun ZFS Storage Appliance (ZFSSA) storage when used with Oracle Database Enterprise Edition 11.2.0.3 and above
* Oracle offers the ability to manage NFS using a feature called Oracle Direct NFS (dNFS). Oracle Direct NFS implements NFS V3 protocol within the Oracle database kernel itself. Oracle Direct NFS client overcomes many of the challenges associated with using NFS with the Oracle Database with simple configuration, better performance than traditional NFS clients, and offers consistent configuration across platforms.

NEW QUESTION 12
In your database, there are tablespaces that were read-only when the last backup was taken. These tablespaces have not been made read/write since then. You want to perform an incomplete recovery on the database by using a backup control file.

A. You cannot export data from a remote database.
B. You can rename tables during import.
C. You can overwrite existing dump files during export.
