(Choose all that apply.)A.A deleted data fileB.All control files deletedC.A failed disk controller with access to disks storing data filesD.A disk drive crash on a non-mirrored storage array containing data filesE.All of the aboveAnswer: EAll these failures will require media recovery. Each failure will make a database file unavailable, which will mean that a restoration and recovery is needed.Chapter: 102.In which of these modes must a database be in order for a complete database recovery up to the point of failure to be performed?A.NOARCHIVELOGB.ARCHIVELOGC.ExportD.LOGAnswer: BComplete recovery up to the point of failure can only be performed when the database is in ARCHIVELOG mode.Chapter: 103.What is the type of recovery being performed when transactions are not applied and the database is NOARCHIVELOG mode?A.Complete recoveryB.Partial recoveryC.Incomplete recoveryD.No recoveryAnswer: AComplete recovery in NOARCHIVELOG mode is the correct answer. Even though you are performing a complete recovery, not all transactions are being applied and there can be data missing. This is because the database is not in ARCHIVELOG mode or is not generating archived logs.Chapter: 104.What command is required to relocate files in a user-managed recovery?A.ALTER DATABASE RENAME FILEB.SET NEWNAMEC.ALTER DATABASE SET NEWNAMED.ALTER DATABASE NEWNAME FILEAnswer: AThe ALTER DATABASE RENAME FILE command is used for user-managed backups.Chapter: 105.You make cold database backups including a read-only tablespace and then you make the tablespace read-write. Before the next weekly backup, the tablespace is made read-write and you need to perform recovery on that tablespace. What option must be performed?A.No recovery is needed because the tablespace was backed up read-only.B.No recovery is needed because the tablespace did not have many changes made in it after it was made read-write.C.Recovery is needed because the tablespace was made read-write and the backup was read-only.D.Restoring the read-only tablespace is all that is needed.Answer: CRecovery is needed when a read-only tablespace is made read-write and the backup was taken when the tablespace was read-only. This means that the SCNs in the headers of the data files have changed and will need to be resynchronized with the rest of the database during the recovery process.Chapter: 106.What RMAN command is required to recover a database in NOARCHIVELOG mode?A.RESTOREB.RECOVERC.SET NEWNAMED.SWITCHAnswer: AThe RESTORE command is responsible for the recovery process when the database is in NOARCHIVELOG mode because no recovery is necessary.Chapter: 107.What RMAN command is responsible for applying incremental backups and archived logs?A.RESTOREB.RECOVERC.SET NEWNAMED.SWITCHAnswer: BThe RECOVER command applies incremental backups and archived logs to the recovery process.Chapter: 108.When using RMAN, what mode does the database need to be in to perform a database restore and recovery?A.OpenedB.NomountC.ClosedD.MountAnswer: DThe database should be mounted to perform a database restore and recovery so that the control file can be read and the target database can be connected.Chapter: 109.The SWITCH command is responsible for which of the following activities during the relocation process of database files? A.Renaming the locationB.Updating the control fileC.Moving the physical filesD.Updating the files in the data dictionaryAnswer: BThe SWITCH command is responsible for updating the control file with the new location of the files that have been moved.Chapter: 1010.Which of the following recoveries doesn't require you to recover the database?A.Read-only tablespace backup and tablespace was read-only when recoveredB.Read-only tablespace backup and tablespace was read-write when recoveredC.Read-write tablespace backup and tablespace was read-only when recoveredD.Read-write tablespace backup and tablespace was read-write when recoveredAnswer: AWhen the tablespace is read-only for the backup and read-only during the recovery, no recovery is needed. The data files of the read-only tablespace can be restored because there is no change to the SCN of data file headers.Chapter: 1011.What are the read-only tablespace recovery scenarios? (Choose all that apply.)A.Read-only backup to read-only recoveryB.Read-only backup to read-write recoveryC.Read-write backup to read-write recoveryD.Read-write backup to read-only recoveryAnswer: A, B, DThe scenarios for read-only tablespace recovery are read-only backup to read-only recovery, read-only backup to read-write recovery, and read-write backup to read-only recovery.Chapter: 1012.What type of read-only recovery could the DBA avoid if they are following recommended procedures?A.Read-only backup to read-only recoveryB.Read-only backup to read-write recoveryC.Read-write backup to read-write recoveryD.Read-write backup to read-only recoveryAnswer: DEvery time you make a tablespace read-only, you should conduct a backup shortly thereafter. This eliminates the need to conduct a recovery in the read-write backup to read-only recovery scenario.Chapter: 1013.What is unique about a RMAN image copy? A.It can only back up data files.B.It can only back up to tape.C.It can only back up to disk.D.It cannot back up control files.Answer: CThe RMAN image copy is similar to an OS copy.

(Choose all that apply.)A.Direct-path loadB.Conventional loadC.Default-path loadD.External-path loadAnswer: A, B, DThe conventional load is the default load that performs normal SQL command processing. The direct-path load performs an expedited processing that bypasses the buffer and writes directly to data files. The external-path load is a load used for processing external files. See Chapter 15 for more information.Chapter: 10160.What are the three primary network configurations? A.N-tier architectureB.Single-tier architectureC.Multi-tier architectureD.Two-tier architectureAnswer: A, B, DThe three primary network configurations are single-tier, two-tier, and n-tier architecture. Single-tier was the predominant architecture for many years when the mainframe dominated the corporate environment. Two-tier architecture came into vogue with the introduction of the PC and has been a dominant architecture ever since. With the inception of the Internet, more organizations are turning towards n-tier architecture as a means to leverage many computers and enhance flexibility and performance of their applications. See Chapter 1 for more information.Chapter: 10161.Which of the following recoveries can be performed when the database is in ARCHIVELOG mode?A.Only incomplete recoveryB.Only complete recoveryC.Only partial recoveryD.Complete recovery and incomplete recoveryAnswer: DWhen the database is in ARCHIVELOG mode, both complete and incomplete recovery can be performed. See Chapter 7 for more information.Chapter: 10162.What is the primary purpose of using checkpoints?A.To decrease free memory buffers in the SGAB.To write non-modified database buffers to the database files and to synchronize the physical structures of the database accordinglyC.To record modified database buffers that are written to the database files and to synchronize the physical structures of the database accordinglyD.To increase free memory buffers in the SGA Answer: CThe main purpose of the database checkpoint is to record that the modified buffers have been written to the data files and to establish data consistency, which enables faster recovery in the event of a failure. See Chapter 6 for more information.Chapter: 10163.What command would you use to retain a backup past the retention date?A.HOLDB.RETAINC.KEEPD.STOREAnswer: CThe KEEP command causes a backup to be kept past the retention setting in the database. See Chapter 12 for more information.Chapter: 10164.Which view can be used to identify clean-up issues after a failed hot or online backup?A.V$BACKUPB.ALL_BACKUPC.USER_BACKUPD.DBA_BACKUPAnswer: AThe V$BACKUP view can be used to identify whether a database is actively being backed up or not.

EdgeTests/4064c18BONUS EXAM 11. You are the production and development DBA for a financial database and application. You have multiple development and testing environments to support your production database environment. One of the development environments is no longer necessary. How can you remove the incarnation of the database from recovery catalog?A. Perform a RESET on the development database incarnation.B. Perform a RESYNCH on the development database incarnation.C. Run the execute dbms_rcvcat.unregisterdatabase procedure for development database incarnation.D. Deleting the database from the filesystem is all that is necessary.Answer: CThe stored procedure execute dbms_rcvcat.unregisterdatabase will unregister a target database in the recovery catalog. This should be run as the recovery catalog owner for any database that you want to remove from the recovery catalog. See Chapter 13 for more information.Chapter: 1022. A client attempting to connect to an Oracle server received the following error:ORA-12198 "TNS: could not find path to destination"Which of the following explains why this error was received? A. The user entered an invalid user ID.B. The user entered an invalid net service name.C. The client found an entry for the service in the tnsnames.ora file but the service specified was not found.D. The Oracle listener process was not started.Answer: CThis error could be caused by a situation in which the service name in the tnsnames.ora file was invalid. See Chapter 3 for more information.Chapter: 1023. Study the RMAN script below. Choose the best answer to describe its function.RMAN> create script complete_bac{2> allocate channel c1 type disk;3> allocate channel c2 type disk;4> backup database;5> backup archivelog all;6> }A. This will create a RMAN script called complete_bac.B. This will create and store a RMAN script called complete_bac.C. This will create and execute a RMAN script called complete_bac.D. This will store a RMAN script called complete_bac.Answer: BThe create script will create and store a script in the recovery catalog for later use. See Chapter 13 for more information.Chapter: 1024. What type of failure scenarios is automatically performed by Oracle?A. User processB. Media failureC. Instance failure D. Statement failureAnswer: CInstance failure is automatically recovered by Oracle when the database instance is halted abruptly, such as it is during a power outage. Oracle handles this when the database gets started by reading the current online redo log and reapplying all the transactions in the redo log. This is sometimes known as the roll forward and rollback process because all the transactions are applied committed or uncommitted. Only the committed changes remain and the database is consistent from before the instance failure. See Chapter 5 for more information.Chapter: 1025. The Virtual Interface (VI) protocol support provided by Oracle Net is used specifically for which of the following? A. Wide area networksB. Local area networksC. System areas networksD. None of the aboveAnswer: CThe VI protocol is designed to support system area networks (SANs). SANs are configurations of multiple servers with high-speed interconnects between them. See Chapter 1 for more information.Chapter: 1026. What type of user-managed incomplete recovery might require the following query?select sequence#,first_change#,next_change#,first_timefrom v$log_history; A. Time-basedB. Change-basedC. Cancel-basedD. Stop-basedAnswer: BChange-based recovery is based upon a unique SCN number that each transaction uniquely contains. This could require you to determine which SCN ranges are in a redo log file. See Chapter 11 for more information.Chapter: 1027. When you first use a target database with RMAN, which command do you need to execute first to store information about the target database?A. REGISTERB. UNREGISTERC. RESETD. UNSETAnswer: AThe REGISTER command stores information about the target database. This command is run the first time a target database will be used within RMAN. See Chapter 13 for more information.Chapter: 1028. Which of the following memory structures temporarily stores the committed and uncommitted transactions before they are all written to disk?A. Data block buffersB. Redo log bufferC. Shared PoolD. Large PoolAnswer: BThe committed or uncommitted transactions, which consist of all transactions, are stored in the redo log buffers before they are written to the redo logs. See Chapter 6 for more information.Chapter: 1029. You have stopped the listener process on the Oracle Server. Which one of the following statements would be TRUE because the listener is no longer running?A. Connections established prior to the listener being stopped will be disconnected.B. Only bequeath connections will no longer be possible, but Shared Server connections will be possible.C. You will not be able to stop or start the Oracle server until the listener is restarted.D. If a client issued the following statement "sqlplus system/manager@prod," the command may fail with a "ORA-12541: TNS:no listener" error.Answer: DThe command issued from the client would need to contact the listener in order to establish a connection to the Oracle Server. The client would contact the server and discover that the listener is not active. See Chapter 2 for more information.Chapter: 10210. Which of the following processes can be performed when the database is in NOARCHIVELOG mode?A. Only incomplete recoveryB. Only complete recoveryC. Only partial recoveryD. Complete recovery and incomplete recoveryAnswer: AWhen the database is in NOARCHIVELOG mode, only incomplete recovery can be performed. However, there is one exception to this rule-if the online redo logs have not been written over since the last backup. See Chapter 7 for more information.Chapter: 10211. What action does the PL/SQL procedure sys.dbms_logmnr_d.build perform?A. Builds an external data dictionaryB. Builds a data extraction libraryC. Builds database procedures for LogMinerD. Builds database libraries for LogMinerAnswer: AThe sys.dbms_logmnr_d.build procedure builds the external data dictionary for LogMiner. See Chapter 5 for more information.Chapter: 10212. You must perform a complete database restore and then recover appropriately for the circumstances. The only thing you know about the recovery is that there is a bad transaction, which corrupted the database. What type of recovery should you perform?A. Time-based at the time just after the corrupt transactionB. Change-based just prior to a certain SCN that contained the corrupt transactionC. Cancel-based at a determined point in timeD. Complete recovery because not enough information is knownAnswer: BChange-based recovery is based upon a unique SCN number that each transaction contains. If you know there is a bad transaction that corrupted the database, you could identify the approximate SCN numbers and recover prior to the SCN of the bad transaction. See Chapter 11 for more information.Chapter: 10213. You are a DBA that has clients connecting from a Windows NT environment. You are using the localnaming method for names resolution. You want to place the Oracle Net client files in a non-default location. Which of the following would you do?A. Update the TNS_ADMIN entry in the Windows NT Registry to point to the new location of the Oracle Net files.B. Update the TNS_ADMIN entry in the tnsnames.ora file to point to the new location of the Oracle Net files.C. Update the NAMES.DIRECTORY_PATH in the sqlnet.ora file to point to the location of the Oracle Net files.D. Because you are using the localnaming method, there would be no Oracle Net files necessary on the clientAnswer: AThe TNS_ADMIN entry would have to be updated in the Windows NT Registry to point to the location of the files. Oracle will check for the existence of this entry when it is searching for the client-side Oracle Net files. See Chapter 3 for more information.Chapter: 10214. Which of the following actions modifies the RMAN repository so that it can store more information?A. Increasing the value of the CONTROL_FILE_RECORD_KEEP_TIME parameterB. Increasing the size of the default tablespace of RMAN schema ownerC. Increasing the size of the recovery catalogD. The RMAN repository cannot be increased.Answer: AThe RMAN repository is the control file of the target database when the recovery catalog is not being used. The size of the control file can be increased by increasing the value of the CONTROL_FILE_RECORD_KEEP_TIME parameter. This value can be anywhere from 1 to 365. See Chapter 8 for more information.Chapter: 10215. What type of connection is possible when the underlying operating system supports inheritance of endpoints?A. Shared serverB. Bequeath connectionC. Redirect connectionD. Dedicated serverE. None of the aboveAnswer: BBequeath connections are possible when the underlying operating system supports inheritance of endpoints. Otherwise, the system must perform a redirect. This requires additional communication between the client and listener. See Chapter 2 for more information.Chapter: 10216. When you are performing a backup, which of the following should be included?A. A copy of the data files onlyB. A copy of the data files and archived logsC. A copy of the data files, the archived logs, and the control filesD. A copy of the data files, the archived logs, the control files, and the parameter filesAnswer: DWhen you copy the data files, archived logs, control files, and parameter files, you are performing a whole or complete database backup. This is always a good idea if possible because it allows the whole database to be restored if necessary. See Chapter 9 for more information.Chapter: 10217. How many more log archive destinations does the LOG_ARCHIVE_DEST_n parameter support in Oracle9i than were previously supported in Oracle8i?A. 1B. 3C. 5D. 10Answer: CLOG_ARCHIVE_DEST_n (n being an integer value) is responsible for 10 archive locations in Oracle9i. In Oracle8i, only a maximum of 5 locations was supported. See Chapter 7 for more information.Chapter: 10218. Which of the following commands move data files in the RMAN recovery process? (Choose all that apply.)A. SET NEWFILEB. SET RENAMEC. SET NEWNAMED. SWITCHAnswer: C, DThe SET NEWNAME and SWITCH commands work together to restore RMAN backups to new locations. The SET NEWFILE and SET NEWNAME are not valid command syntax. See Chapter 10 for more information.Chapter: 10219. Oracle Connection Manager provides all of the following except:A. Centralized namingB. MultiplexingC. Network access controlD. Cross-protocol connectivityAnswer: AConnection Manager provides multiplexing, network access control, and cross-protocol connectivity. It does not provide a centralized naming solution. Centralized naming is provided by Oracle Internet Directory, or in previous version of Oracle, Oracle Names Server. See Chapter 1 for more information.Chapter: 10220. You are the DBA of a production database that does not run in ARCHIVELOG mode. The database cycles through all of the redo logs about two times a day. The backups for the database occur every Sunday. You experience a media failure on Wednesday. What is the best recovery you can perform?A. Complete recovery, if all of the redo logs are available.B. Incomplete recovery, losing all transactions that occurred after the backup.C. Complete recovery, losing all transactions that occurred after the backup.D. Incomplete recovery, only losing the redo logs after the time-based recovery.Answer: CYou can completely recover everything from the last full backup, but cannot apply transaction logs. Incomplete recovery in the Oracle world means UNTIL CANCEL, UNTIL TIME, or SCN. See Chapter 10 for more information.Chapter: 10221. Which statement best describes the recovery catalog?A. A mandatory feature of RMANB. An optional feature of RMAN that stores metadata about the backupsC. A mandatory feature of RMAN that stores metadata about the backupsD. An optional feature of RMANAnswer: BThe recovery catalog is an optional feature of RMAN. Though Oracle recommends that you use it, it isn't required. One major benefit of the recovery catalog is that it stores metadata about backups in a database that can be reported or queried. See Chapter 8 for more information.Chapter: 10222. What SQL*Loader command does not overwrite existing data?A. REPLACEB. APPENDC. REUSED. NEWAnswer: BThe APPEND command does not delete or overwrite existing table data. See Chapter 15 for more information.Chapter: 10223. Which of the following is another name for a bequeath connection?A. Indirect connectionB. Redirect connectionC. Direct hand-off connectionD. Shared connectionAnswer: CBequeath connections are also called direct hand-off connections because they pass control directly to a shared server or to a dedicated server process. See Chapter 2 for more information.Chapter: 10224. Which RMAN command would you use to make a backup set available?A. CHANGEB. MAKEC. FORCED. EXPIREAnswer: AThe CHANGE command makes the backup set either available or unavailable in the recovery catalog. The other commands are invalid. See Chapter 12 for more information.Chapter: 10225. Which RMAN command will show the availability status of a DATAFILECOPY command?A. LIST COPY OF DATABASEB. LIST COPY OF DATAFILEC. DATAFILE COPY D. CATALOG DATAFILEAnswer: AThe LIST COPY OF DATABASE will show the status of data file copies for a particular database. See Chapter 15 for more information.Chapter: 102

EdgeTests/4064c1926. User-managed backup and recovery best defines which of the following statements?A. Custom backup and recovery performed with OS commands and database commands B. Non-automated RMAN-based backupsC. A new type of backup that uses RMAN but is performed by a userD. Automated RMAN-based backupAnswer: AUser-managed backup is the term used to describe the standard backups that have been used from the inception of Oracle. These backups are usually custom written through the use of OS and database commands. See Chapter 9 for more information.Chapter: 10227. You receive an unusual request to restore a copy of the production financial database from the last year to compare financial numbers in some tables currently not available in the existing production database. How can you check if you still have the backup media from that timeframe?A. Perform a REPORT SCHEMA to check if the database and backup media are available.B. Perform a LIST BACKUP to check if the database and backup media are available.C. Perform a CROSSCHECK of the recovery catalog and backup media.D. Perform a CHANGE of the recovery catalog and the backup media.Answer: CThe CROSSCHECK command will compare the recovery catalog contents and associated media. If your tape rotation cycle is 30 days, you would have supporting backup media for only 30 days, even if your recovery catalog had data for over a year. See Chapter 12 for more information.Chapter: 10228. You have to perform a large DBA maintenance activity involving the partial loading of a temporary table from a very large table containing invoicing information for more than a year. What would be the quickest way to create the temporary table to perform this activity?A. Conventional load export and import.B. Create a table using direct-load insert.C. Conventional path SQL*Loader.D. Create Table as Select with logging turned on.Answer: BDirect-load insert is best used for batch loads of data or maintenance activities, such as rebuilding or unloading tables. This would be quicker to do than all of the other options. The conventional-load export would require you to build an export dump file and then import back into the database while in conventional mode. The SQL*Loader option would require setup to build the input, or data, file and control file, and then reload. The Create Table as Select (CTAS) option would require little setup, but because logging is turned on, the process would slow down. See Chapter 15 for more information.Chapter: 10229. All of the following would be network design considerations except:A. Network complexityB. Network securityC. Interfacing with new and existing systemsD. Backup and recovery issues for the Oracle serverAnswer: DBackup and recovery would not be considered a network design consideration. This is more of an Oracle server administration issue. See Chapter 1 for more information.Chapter: 10230. There was a complete disaster that forced you to rebuild a database environment from yesterday's backup. The most current 20 offline redo logs were lost when the complete disaster occurred. What components would you need to completely rebuild a database to a point as close as possible before the disaster?A. All data files, all control files, parameter files, and only online redo logsB. All data files, one control file, parameter files, and all redo logsC. All data files, one control file, parameter files, and some of the available offline redo logsD. All data files, parameter files, and all online redo logsAnswer: BThe type of recovery that would restore and recover a database to some point before a failure is best described as an incomplete recovery. Also, the most current 20 offline redo logs (archived logs) are unavailable. This means that you cannot perform a complete recovery. The components required to perform a complete recovery are all the necessary data files, at least one current control file, parameter files, and all of the available offline redo logs (archived logs). The online redo logs will not allow you to roll forward from the backup. Of the archived logs available, you will only be able to roll forward as far as you have archived logs. You will also need at least a control file or a backup control to recover the database. See Chapter 10 for more information.Chapter: 10231. Which of the following views can be used to identify cleanup issues after a failed hot or online backup?A. V$BACKUPB. ALL_BACKUPC. USER_BACKUPD. DBA_BACKUPAnswer: AThe V$BACKUP view can be used to identify whether a database is actively being backed up or not. See Chapter 9 for more information.Chapter: 10232. Which Oracle background process
