In one of your online transaction processing (OLTP) applications, table keys are frequently updated and queries performed using many different operators.

In addition, reports are generated using complex joins with non-equality operators. What table organization is the best for this workload?

Answer: B

Question No: 35

Examine the following scenario:

->Database is running in ARCHIVELOG mode.

->Complete consistent backup is taken every Sunday.

->On Tuesday the instance terminates abnormally because the disk on which control files are located gets corrupted

->The disk having active online redo log files is also corrupted.

->The hardware is repaired and the paths for online redo log files and control files are still valid.

Which option would you use to perform the recovery of database till the point of failure?

  1. Restore the latest whole backup, perform complete recovery, and open the database

    normally

  2. Restore the latest whole backup, perform incomplete recovery, and open the database with the RESETLOGSoption.

  3. Restore the latest backups control file, perform complete recovery, and open the database with theRESETLOGS option.

  4. Restore the latest backup control file, perform incomplete recovery using backup control file, and open thedatabase with the RESETLOG option.

Answer: D

Question No: 36

You plan to use Flashback Drop feature to recover a dropped table SALES_EMP. No other table with the same name exists in the schema.

You query RECYCLEBIN and find multiple entries for the SALES_EMP table as follows: You then issue the following statement to recover the table:

SQLgt; SELECT object_name, original_name, droptime FROM recyclebin;

Latesttests 2018 PDF and VCE

What would be the outcome of the precedent statement?

  1. It retrieves the latest version of the table from the recycle bin

  2. It retrieves the oldest version of the table from the recycle bin

  3. It retrieves the version of the table for which undo information is available

  4. It returns an error because the table name is not specified as per the names in the OBJECT_NAME column

Answer: A

Question No: 37

Your database is running in ARCHIVELOG mode. You have been taking backups of all the data files and control files regularly.

You are informed that some important tables in the BILLING tablespace have been dropped on February 28, 2007 at 10.30 AM and must be recovered.

You decide to perform an incomplete recovery using the following command: SQLgt; RECOVER DATABASE UNTIL TIME #39;2007-02-28:10:15:00#39;;

Identify the files that must be restored to recover the missing tables successfully.

  1. Restore the backup of all the data files.

  2. Restore the backup of all the data files and the control file.

  3. Restore the backup of only the data files that contain the dropped tables.

  4. Restore the backup of all the data files belonging to the tablespace containing the dropped tables.

Answer: A

Question No: 38

Which statements describe the capabilities of the DBMS_NETWORK_ACL_ADMIN package? (Choose all that apply.)

  1. It can be used to allow the access privilege settings for users but not roles.

  2. It can be used to allow the access privilege settings for users as well as roles.

  3. It can be used to control the time interval for which the access privilege is available to a user.

  4. It can be used to selectively restrict the access for each user in a database to different host computers.

  5. It can be used to selectively restrict a user#39;s access to different applications in a specific host computer.

    Answer: B,C,D

    Question No: 39

    Your database is open and running in ARCHIVELOG mode.

    You take RMAN full backups every Sunday night.

    On Monday morning, while querying the user1.emoloyees table, you receive the following error message:

    01578: ORACLE data block corrupted (file # 5, block # 51) ORA-0lll0: data file 5: #39;/u01/app/oracle/oradata/orcl/exanple0l.dbf*

    You need to recover from this while ensuring that:

    1. The data file remains online.

    2. Mean Time To Recover (MTTR) is minimized as much as possible

      You have no backup control file, but all the archived logs are accessible. Which method will best satisfy the requirements?

      1. flash back the corrupted blocks

      2. use the DBMS_REPAIR package

      3. use RMAN tablespace point in time recovery

      4. use the RMAN BLCCKRECOVER command

      5. perform a table point in time recovery with datapump export and import

Answer: D

Question No: 40

You execute the following command to set the redundancy retention policy in Recovery Manager (RMAN):

RMANgt; CONFIGURE RETENTION POLICY TO REDUNDANCY 3;

Identify the statement that correctly describes the implications of this command.

  1. when there are already three backups, for the fourth backup RMAN removes the oldest backup.

  2. When there are already three backups, for the fourth backup RMAN marks the oldest backup as obsolete.

  3. the number of backups that are retained is equal to three and it includes full,

    incremental, and cumulativebackups.

  4. when there are already three backup, one of the existing backups must be removed manually before takingthe fourth backup.

Answer: B Explanation:

Configuring a Redundancy-Based Retention Policy

The REDUNDANCY parameter of the CONFIGURE RETENTION POLICY command specifies how many full or level 0 backups of each data file and control file that RMAN should keep. If the number of full or level 0backups for a specific data file or control file exceeds the REDUNDANCY setting, then RMAN considers the extra backups as obsolete. The default retention policy is REDUNDANCY 1.

As you produce more backups, RMAN keeps track of which ones to retain and which are obsolete. RMAN retains all archived logs and incremental backups that are needed to recover the non obsolete backups.

Assume that you make a full backup of data file 7 on Monday, Tuesday, Wednesday, and Thursday. You now have four full backups of this data file. If REDUNDANCY is 2, then the Monday and Tuesday backups are obsolete. If you make another backup on Friday, then the Wednesday backup of data file 7 becomes obsolete. Assume a different case in which REDUNDANCY is 1. You run a level 0 database backup at noon on Monday, a level 1 cumulative backup at noon on Tuesday and Wednesday, and a level 0 backup at noon on Thursday. Immediately after each daily backup you run the command DELETE OBSOLETE. The Wednesday DELETE command does not remove the Tuesday level 1 backup because this backup is not redundant: the Tuesday level 1 backup could be used to recover the Monday level 0 backup to a time between noon on Tuesday and noon on Wednesday. However, the DELETE command on Thursday removes the previous level 0 and level 1backups.

Run the CONFIGURE RETENTION POLICY command at the RMAN prompt, as in the following example: CONFIGURE RETENTION POLICY TO REDUNDANCY 3;
