第5题:
The command succeeds but it retrieves only the disk names.
The command produces an error because the ASM instance is down.
The command succeeds but it shows only the status of the ASM instance.
The command succeeds and retrieves information by scanning the disk headers based on an ASM_DISKSTRING value.
第6题:
The au_size disk group attribute determines the size of allocation units in the disk group.
The allocation unit size may vary but the extent size is fixed.
The allocation unit size and extent size are fixed for all the disks in a disk group and cannot be changed.
Extent management is completely automated.
第7题:
Disk should be mirrored across separate storage enclosures.
Disk heartbeats should be added over multiple disk adapters.
Disk major and minor numbers should be set as unique across nodes.
Disk adapter queue_depth should be increased from the default values.
第8题:
ALTER DISKGROUP dg1 UNDROP disk2,disk3,disk5
ALTER DISKGROUP dg1 UNDROP

You cannot cancel the pending disk drops
第9题:
SSD disk encryption does not consume space
SSD disk is faster than FC disk for encryption
no space is wasted due to encryption on DS8700
there is higher processor utilization using FDE drives
第10题:
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.
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.
The disk group will be automatically rebalanced during the drop operation. Once the rebalancing is complete,the disk will be dropped.
This command will fail because you cannot drop a specific disk in an ASM disk group.
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.
第11题:

The command produces an error because the ASM instance is down.
The command succeeds but it shows only the status of the ASM instance.
The command succeeds and retrieves information by scanning the disk headers based on an ASM_DISKSTRING value.

Which of the following should be implemented to increase the reliability of Fast Disk Takeover?()
第13题:
Consider the following scenario for your database: - Backup optimization is enabled in RMAN. - The recovery window is set to 7 days in RMAN. - The most recent backup to disk for the TOOLS tablespace was taken on November 3, 2007. - The TOOLS tablespace is read-only since November 4, 2007. On November 23, 2007, you issue the RMAN command to back up the database to disk. Which statement is true regarding the backup of the TOOLS tablespace?()

第15题:
You have just added three new hard disks to your Windows 2000 Professional computer. You want to configure all of the disks as two drives. You want the two drives to be as equal in size as possible. You want to configure the non-system drive for the best optimal performance. What should you do?()
第16题:
It repairs blocks that have read disk I/O errors.
It checks whether the alias metadata directory and the file directory are linked correctly.
It repairs blocks by always reading them from the mirror copy and writing them to the original location.
It reads the blocks from a good copy of an ASM mirror and rewrites them to an alternate location on disk if the blocks on the original location cannot be read properly.

disk scrub and BIOS setting scrub
第18题:
As ASM instance mounts an ASM control file
An ASM instance uses the ASMB process for rebalancing of disks within a disk group
Automatic Memory Management is enabled in an ASM instance even when the MEMORY_TARGET parameter is not set explicitly
An RDBMS instance gets connected to an ASM instance using ASMB as a foreground process when the database instance is started
第19题:
It saves disk space and reduces memory usage.
It saves disk space but has no effect on memory usage.
It incurs extra CPU overhead during DML as well as direct loading operations.
It incurs extra CPU overhead during DML but not direct loading operations.
It requires uncompress operation during I/O.
第20题:
If disk scrub is enabled, all BIOS settings for the server are erased.
If disk scrub is enabled, all the data access on any local drives is destroyed.
If disk scrub is enabled, the LSI active RAID is destroyed but data is still preserved.
If disk scrub is disabled, all data on any local drives is preserved, including the local storage configuration.
If disk scrub is enabled, all data on any local drives is preserved, including the local storage configuration.
第21题:
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.
