Q41. You have installed two 64G flash devices to support the Database Smart Flash Cache feature on your database server that is running on Oracle Linux.
You have set the db_smart_flash_file parameter:
DB_FLASH_CACHE_FILE= ‘ /dev/f lash_device_1‘,‘ /dev/f lash_device_2‘
How should the D3_flash_cache_size be configured to use both devices?
A. Set DB_FLASH_CACHE_SIZE=64G.
B. Set D3_FLASH_CACHE_SIZE=64G, 64G.
C. Set D3_FLASK_CACKE_SI2E=i28G.
D. db_flash_cache_SI2E is automatically configuredby the instance at startup.
Answer: B
Explanation: * Smart Flash Cache concept is not new in Oracle 12C - DB Smart Flash
Cache in Oracle 11g.
In this release Oracle has made changes related to both initialization parameters used by
DB Smart Flash cache. Now you can define many files|devices and its sizes for “Database
Smart Flash Cache” area. In previous releases only one file|device could be defined.
DB_FLASH_CACHE_FILE = /dev/sda, /dev/sdb, /dev/sdc
DB_FLASH_CACHE_SIZE = 32G, 32G, 64G
So above settings defines 3 devices which will be in use by “DB Smart Flash Cache”
/dev/sda – size 32G
/dev/sdb – size 32G
/dev/sdc – size 64G
New view V$FLASHFILESTAT – it’s used to determine the cumulative latency and read
counts of each file|device and compute the average latency
Q42. You are administering a database that supports data warehousing workload and Is running in noarchivelog mode. You use RMAN to perform a level 0 backup on Sundays and level 1 Incremental backups on all the other days of the week.
One of the data files is corrupted and the current online redo log file is lost because of a media failure.
You want to recover the data file.
Examine the steps involved in the recovery process:
1.Shut down the database instance.
2.Start up the database instance in nomount state.
3.Mount the database.
4.Take the data file offline.
5.Put the data file online.
6.Restore the control file.
7.Restore the database.
8.Restore the data file.
9.Open the database with the resetlog option.
10.Recover the database withthe noredo option.
11.Recover the data file with the noredo option.
Identify the required steps in the correct order.
A. 4, 8, 11, 5
B. 1, 3, 8, 11, 9
C. 1, 2, 6, 3, 7, 10, 9
D. 1, 3, 7, 10, 9
E. 1, 2, 6, 3, 8, 11, 9
Answer: C
Q43. You want the execution of large database operations to suspend, and then resume, in the event of space allocation failures.
You set the value of the initialization parameter resumable_timeout to 3600.
Which two statements are true?
A. A resumable statement can be suspended and resumed only once during execution.
B. Data Manipulation Language (DML) operations are resumable, provided that they are not embedded in a PL/SQL block.
C. A suspended statement will report an error if no corrective action has taken place during a timeout period.
D. Before a statement executes in resumable mode, the alter session enable resumable statement must be issued in its session.
E. Suspending a statement automatically results in suspending a transaction and releasing all the resources held by the transaction.
Answer: A,D
Q44. Which three statements are true about the SQL*Loader utility?
A. It can be used to load data from multiple external files into multiple tables.
B. It can be used to extract and reorganize data from external files, and then load it into a table.
C. It can be used to load data from external files using direct path only.
D. It can be used to create tables using data that is stored in external files.
E. It can be used to generate unique sequential values in specified columns while loading data.
Answer: A,D,E
38. You wish to create jobs to satisfy these requirements:
1. Automatically bulk load data from a flat file.
2.Rebuild indexes on the SALES table after completion of the bulk load.
How would you create these jobs?
A. Create both jobs by using Scheduler raised events.
B. Create both jobs using application raised events.
C. Create one job to rebuild indexes using application raised events and another job to perform bulk load using Scheduler raised events.
D. Create one job to rebuild indexes using Scheduler raised events and another job to perform bulk load by using events raised by the application.
Answer: A
Q45. Which two statements are true about service creation for pluggable databases (PDBs)?
A. When a PDB is created, a service is automatically started in the instance with the same name as the PDB.
B. The defaultservice that is automatically created by a database at the time of PDB creation can be dropped, provided a new additional service is created.
C. A database managed by Oracle Restart can have additional services created or existing services modified by usingthe srvctl utility for each PDB.
D. Only a common user can create additional services for a PDB.
E. When a PDB is created, a service with the same name as the PDB is created in the PDB.
Answer: C,D
Q46. Users report this error message when inserting rows into the orders table:
ERROR atline1:
ORA-01654f:unable to extend index USERS.ORDERS_IND by 8in tablespace INDEXES
You determine that the indexes tablespace is out of space and there is no free space on the filesystem used by the Oracle database.
Which two must you do to fix this problem without affecting currently executing queries?
A. drop and re-create the index
B. coalesce the orders.ind index
C. coalesce the indexes tablespace
D. perform an on line table rebuild using dbns_redefir.ition.
E. rebuild the index online moving it to anothertablespace that has enough free space for the index
Answer: A,C
Q47. Identify three reasons for using a recovery catalog with Recovery Manager (RMAN).
A. to store backup information of multiple databases in one place
B. to restrict the amount of space that is used by backups
C. to maintain a backup for an indefinite period of time by using the KEEP FOREVER clause
D. to store RMAN scripts that are available to any RMAN client that can connect to target databasesregistered in the recovery catalog
E. to automatically delete obsolete backups after a specified period of time
Answer: A,C,D
Q48. Consider the following scenario for your database:
Backup optimization is enabled in RMAN.
Therecovery window is set to seven days in RMAN.
The most recent backup to disk for the tools tablespace was taken on March 1,
...
2013.
. The tools tablespace is read-only since March 2, 2013.
On March 15, 2013, you issue the RMAN command to back up the databaseto disk.
Which statement is true about the backup of the tools tablespace?
A. The RMAN backup fails because the tools tablespace is read-only.
B. RMAN skips the backup of the tools tablespace because backup optimization is enabled.
C. RMAN creates a backup of the tools tablespace because backup optimization is applicable only for the backups written to media.
D. RMAN creates a backup of the tools tablespace because no backup of the tablespace exists within the seven-day recovery window.
Answer: D
Q49. You set the following parameters in the parameter file and restart the database instance:

MEMORY__TARGET=500M
PGA_AGGREGATE_TARGET=90M
SGA_TARGET=270M
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: C,E
