Error log analysis indicates that a disk is starting to fail and will need to be replaced. The failing disk contains multiple logical volumes which span multiple disks. A free disk has been added to the failing disk’s volume group.Which of the following is the most efficient method to move the data from the failing disk to the new disk？（）A、Back up the data， remove the failing disk from the volume group， then restore the data to the new disk.B、Use the migratepv command to move data from one disk to another and then remove the failing disk from the volume group.C、Use the mirrorvg command to mirror the data to the new disk， break the mirror and then remove the failing disk from the volume group.D、Create a new filesystem on the new disk and use the mv command to move the data to the new filesystem， and then remove the failing disk from the volume group.

What is the net effect of the following command？（） alter diskgroup dgroup1 drop disk abc；A、 The disk ABC will be dropped from the disk group. Since you did not issue a rebalance command，the data on that disk will be lost.B、 The command will raise an error indicating that you need to rebalance the disk group to remove the data from that disk prior to dropping the disk.C、 The disk group will be automatically rebalanced during the drop operation. Once the rebalancing is complete，the disk will be dropped.D、 This command will fail because you cannot drop a specific disk in an ASM disk group.E、 The disk drop command will be suspended for a predetermined amount of time，waiting for you to also issue an alter diskgroup rebalance command. Once you have issued the rebalance command，ASM will proceed to rebalance the disk group and then drop the disk.

You are an Oracle DBA responsible for an ASM instance. The disk controller on your system fails. You suspect that the disk itself is okay. You know it will take 24 hours to replace the controller and you don’t want to have to rebuild the disks from scratch. What do you do？（） A、 Take the whole disk group offline and wait for the controller card to be installed. Once it’s installed，bring the disk group online again.B、 Change the ASM parameter ASM_PREFERRED_READ_FAILURE_GROUPS to indicate that you want to read from the non-failed disk. Once the disk controller is replaced，reset the parameter to its original value.C、 You have no choice but to rebuild the disk. Drop the disk from the disk group and wait for the controller to be replaced. Once the controller is replaced， add the disk back into the disk group and allow ASM to rebuild it.D、 If you are using any setting other than REDUNDANCY EXTERNAL for your disk group，you will have to recover any data on that disk from a backup. The database will be unavailable until you can correct the problem and perform recovery.E、 Change the attribute DISK_REPAIR_TIME on the disk group to a time greater than 24 hours.

You are administering a database stored in Automatic Storage Management (ASM). You use RMAN to back up the database and the MD_BACKUP command to back up the ASM metadata regularly. You lost an ASM disk group DG1 due to hardware failure. In which three ways can you re-create the lost disk group and restore the data?（）A、Use the MD_RESTORE command to restore metadata for an existing disk group by passing the existing disk group name as an input parameter and use RMAN to restore the data.B、Use the MKDG command to restore the disk group with the same configuration as the backed-up disk group and data on the disk group.C、Use the MD_RESTORE command to restore the disk group with the changed disk group specification, failure group specification, name, and other attributes and use RMAN to restore the data.D、Use the MKDG command to restore the disk group with the same configuration as the backed-up disk group name and same set of disks and failure group configuration, and use RMAN to restore the data.E、Use the MD_RESTORE command to restore both the metadata and data for the failed disk group.F、Use the MKDG command to add a new disk group DG1 with the same or different specifications for failure group and other attributes and use RMAN to restore the data.

You are the Database Administrator for WonderWeb， which has recently acquired a media company TXGlobal. You have been assigned the task to migrate all the database applications of TXGlobal to the database server of WonderWeb. To accommodate more database applications， you need to add disks to the existing disk group.

Which background process performs this actual rebalancing activity， resulting in the movement of data extents in the disk groups？（） A、 ASMBB、 ARBnC、 RBAL in the ASM instanceD、 RBAL in the database instance
考题
In which situations will the ASM metadata backup help you recover the ASM disk in a disk group？（）A、 when one or more file directory paths are accidentally deleted from an ASM disk groupB、 when one of the disks in a disk group is accidentaly unpluggedC、 when the data file on an ASM disk group gets corruptedD、 when one or more disks in an ASM disk group are lost
