Oracle Database 11g: Administration II
Question No: 61 – (Topic 1)
You are managing an Oracle Database 11g instance with ASM storage. You lost an ASM disk group DATA. You have RMAN backup of data as well as ASM metadata backup. You want to re-create the missing disk group by using the ASMCMD md_restore command.
Which of these methods would you use to achieve this? (Choose all that apply.)
Restore the disk group with the exact configuration as the backed-up disk group, using
the same disk group name, same set of disks, failure group configurations, and data on the disk group.
Restore the disk group with the exact configuration as the backed-up disk group, using the same disk group name, same set of disks, and failure group configurations.
Restore the disk group with changed disk group specification, failure group specification, disk group name, and other disk attributes.
Restore metadata in an existing disk group by passing the existing disk group name as an input parameter.
Answer: B,C,D Explanation: Purpose
The md_restore command restores disk groups from a metadata backup file.
Syntax and Description
md_restore backup_file [-silent]
[-full|-nodg|-newdg -o #39;old_diskgroup:new_diskgroup [,…]#39;] [-S sql_script_file] [-G #39;diskgroup [,diskgroup…]#39;]
Reads the metadata information from backup_file.
Ignore errors. Typically, if md_restore encounters an error, it stops. Specifying this flag ignores any errors.
Specifies to create a disk group and restore metadata.
Specifies to restore metadata only.
-newdg -o old_diskgroup:new_diskgroup]
Specifies to create a disk group with a different name when restoring metadata. The -o option is required with
Write SQL commands to the specified SQL script file instead of executing the commands.
Select the disk groups to be restored. If no disk groups are defined, then all disk groups are restored.

View the Exhibit and examine the disk groups created at the time of migrating the database storage to Automatic Storage Management (ASM).
Why does the FRA disk group initially have more free space even though both DATA and FRA disk groups are provided with the same size?
Because the FRA disk group will not support dynamic rebalancing
Because the FRA disk group is not configured to support mirroring
Because disks in the FRA disk group are not formatted at this stage
Because the FRA disk group will support only a single size of allocation unit

You are managing an Oracle Database 11g instance and an Oracle Database 10g instance on the same machine. Both instances use the ASM instance as storage. Which statement regarding the ASM disk group compatibility attributes are true in this scenario? (Choose all that apply.)
The database-compatibility version settings for each instance must be greater than or equal to the RDBMS compatibility of all ASM disk groups used by that database instances.
RDBMS compatibility and the database version determines whether a database instance can mount the ASM disk group.
The RDBMS compatibility settings for a disk group control the format of data structures for ASM metadata on the disk.
ASM compatibility controls which features for the ASM will be enabled.

The INV_HISTORY table is created using the command:
The following data has been inserted into the INV_HISTORY table:
You would like to store the data belonging to the year 2006 in a single partition and issue
SQLgt; ALTER TABLE inv_history MERGE PARTITIONS
INTO PARTITION sys_py;
What would be the outcome of this command?
It executes successfully, and the transition point is set to #39;1-apr-2006#39;.
It executes successfully, and the transition point is set to #39;15-apr-2006#39;.
It produces an error because the partitions specified for merging are not adjacent.
It produces an error because the date values specified in the merge do not match the date values stored in the table.

In your database, the LDAP_DIRECTORY_SYSAUTH initialization parameter has been set to YES and the users who need to access the database as DBAs have been granted SYSDBA enterprise role in Oracle Internet Directory (OID). SSL and the password file have been configured. A user SCOTT with the SYSDBA privilege tries to connect to the database instance from a remote machine using the command:
$ SQLPLUS scott/tiger@DB01 AS SYSDBA Which DB01 is the net service name.
Which authentication method would be used first?
authentication by password file
authentication by using certificates over SSL
authentication by using the Oracle Internet Directory
authentication by using the local OS of the database server

Question No: 66 – (Topic 2)
Which of the following does the recover command not do?
Restore archived redo logs.
Apply archived redo logs.
Restore incremental backups.
Apply incremental backups.
Restore datafile images.
Question No: 67 – (Topic 2)
What is the purpose of the list expired backup command?
Lists all backups impacted by a resetlogs command
Lists all backups that are subject to retention criteria
Lists all backups that are missing associated physical backup set pieces
Lists the status of datafile backup failures due to the use of the duration command
Lists backups that cannot be used by the restore command because they have been marked as disabled

Your database has a backup that was taken yesterday (Tuesday) between 13:00 and 15:00 hours. This is the only backup you have. You have lost all the archived redo logs generated since the previous Monday, but you have archived redo logs available from the previous Sunday and earlier. You now need to restore your backup due to database loss.
To which point can you restore your database?
13:00 on Tuesday.
15:00 on Tuesday.
Up until the last available archived redo log on Sunday.
To any point; all the redo should still be available in the online redo logs.
The database is not recoverable.
