In your database, all the tablespaces are locally managed. You started Recovery Manager (RMAN) using recovery catalog. The following commands are used in the process of recovering the database by using the backup control file:
In what sequence would you use this process to perform the recovery?()
A.7, 2, 3, 1, 4, 6, 5
B.7, 1, 3, 2, 6, 5, 4
C.2, 1, 7, 6, 3, 5, 4
D.2, 7, 3, 5, 1, 6, 4

The loss of the control file forced you to recreate the control file. After recreating it and opening the database, you find that some of the data files are named as MISSINGnnnnn, where nnnnn is a fivedigit number starting with 0.
What could be the possible reason?()
A.These are the data files that are corrupted.
B.There is no SYSAUX tablespace in your database
C.There is a readonly tablespace in your database.
D.These are the data files that cannot be recovered.
A.drop the readonly tablespace and recreate the tablespace after recovery
B.take data files from the readonly tablespace offline before performing a recovery
C.perform a recovery; status of the tablespace in control file will be changed automatically
D.recovery using backup control file is not possible, so restore all the files from the last full database backup, and then open the database
One of the tablespaces is readonly in your database. The loss of all control files forced you to recreate the control file.
Which operation do you need to perform after recreating the control file and opening the database?()
A.drop and recreate the readonly tablespaces
B.rename the readonly data files to their correct file names
C.change the tablespace status from read/write to readonly
D.recreate the readonly tablespace because it is automatically removed
A.restore the tablespace from the backup; there is no need to apply the redo information
B.restore the full database to recover the data up to the point when you performed the backup
C.restore the tablespace from the backup, and then perform a recovery using the backup control file
D.restore the tablespace from the backup, and then recover the tablespace; all the redo information from the point when the tablespace was made read/write is applied
A.ONLINE
B.REVERSE
C.PARALLEL
D.COMPRESS
E.NOLOGGING
F.COMPUTE STATISTICS
You lost the index tablespace in your database. You decided to recreate the index tablespace and the indexes in the tablespace.
What methods can you use to recreate the indexes?()

B.SQL scripts
C.SQL*Loader
D.Flashback database
E.Recovery Manager (RMAN) script
A.The index tablespace contains bitmap indexes.
B.The index tablespace contains more than one data file.
C.The index tablespace supports only complete recovery.
D.The index tablespace is not a dictionarymanaged tablespace.
E.There is a dependency relationship between a table and its indexes.
In your database, online redo log files are multiplexed and one of the members in a group is lost due to media failure.
How would you recover the lost redo log member?()
A.import the database from the last export
B.restore all the members in the group from the last backup
C.drop the lost member from the database, and then add a new member to the group
D.restore all the database files from the backup, and then perform a complete recovery
E.restore all the database files from the backup, and then perform an incomplete recovery
A user executes a query on the EMP table, which contains thousands of rows, to get details about employees in one of the departments. The user receives the following error: SQL> SELECT ename FROM emp WHERE deptno=10 ORDER BY sal; SELECT ename FROM emp WHERE deptno=10 ORDER BY sal
*
ERROR at line 1:
ORA01157: cannot identify/lock data file 201 see DBWR trace file
ORA01110: data file 201: ’/u01/app/oracle/oradata/orcl/temp01.dbf’
What is a possible reason?()
A.The tempfile belonging to the default temporary tablespace is missing.
B.The database is opened in restricted mode, so queries are not allowed.
C.The default temporary tablespace required to execute the query is offline.
D.The default temporary tablespace required to execute the query is dropped.
E.The default temporary tablespace required to execute the query is readonly.
A.The database opens normally.
B.The database prompts for a database recovery.
C.The database writer writes to a trace file, indicating that the temporary file is not found.
D.The database gets mounted and throws an error indicating that the temporary file requires recovery.

You decided to change the location of the flash recovery area. You executed the following command: Which statement is true?()
Your database operates in ARCHIVELOG mode and usermanaged consistent backups are performed every Sunday night. On Tuesday, at 9:00 a.m. the current log sequence number was 369. Also, on Tuesday you lost the data file belonging to the SYSTEM tablespace and an archivelog file (sequence number 356) that contained redo entries between 8:00 a.m. and 8:30 a.m. With reference to this scenario, what would you do to recover the database?()
A data file became corrupted in your database due to bad sectors on the disk. Because of corruption, you lost all the important tables in that data file.Which method would you use for recovery?()
You have a readonly tablespace on readonly media. You want to perform a media recovery on the existing data files, but using a backup control file. The backup control file indicates that the status of the readonly tablespace was read/write when the control file was backed up. What should you consider?()
You noticed that the index tablespace in your database requires a recovery. However, instead of performing a media recovery, you decided to recreate the indexes in a new tablespace. Which two options would you use to reduce the time it takes to recreate the indexes?()
The current time is 12:00 noon. You want to recover the USERS tablespace from a failure that occurred at 11:50 a.m. You discover that the only member of an unarchived redo log group containing information from 11:40 a.m. onwards is corrupt. With reference to this scenario, if you are not using Recovery Manager (RMAN), which recovery method would you use?()
In which case would you use the Flashback Database feature to perform a recovery?()
Your database operates in ARCHIVELOG mode. Usermanaged consistent backups are performed every Sunday night. On Tuesday, client A drops a table at 8:00 a.m. as follows: SQL> DROP TABLE cust_ord PURGE; Table dropped. Client B executes a query at 9:00 a.m. on the same table as follows: SQL> SELECT * FROM cust_ord;SELECT * FROM cust_ord* ERROR at line 1: ORA00942: table or view does not exist Client B needs the dropped table and reports the problem to you. With reference to this scenario, which action should you take?()

Consider the recovery steps in each of the cases given below: Case 1: Shut down the database and perform a backup. Restore all the data files. Mount the database. Recover the database. Without applying all the redo log files, open the database using the RESETLOGS option. Back up the database. Case 2: Shut down the database and perform a backup. Restore only the data files of the tablespace where user error damaged the data. Mount the database. Recover the database. Open the database with the RESETLOGS option. Back up the database. Case 3:Shut down the database Restore the data files Open the database Perform recovery to the current point in time. Which case has the correct steps for an incomplete recovery?()
