QUESTION 131
When starting up your ASM instance, you receive the following error:

What is the cause of the error?

A.    The ASM_DISKGROUPS parameter is configured for three disk groups: DGROUP1, DGROUP2, and
DGROUP3.
The underlying disks for these disk groups have apparently been lost.
B.    The format of the ASM_DISKGROUPS parameter is incorrect. It should reference the disk group numbers,
not the names of the disk groups
C.    The ASM_POWER_LIMIT parameter is incorrectly set to 1. It should be set to the number of disk groups
being attached to the ASM instance.
D.    The ASM_DISKSTRING parameter is not set; therefore disk discovery is not possible.
E.    There is insufficient information to solve this problem.

Answer: D

QUESTION 132
As DBA for the Rebel Alliance you have decided that you need to facilitate some redundancy in your database. Using ASM, you want to create a disk group that will provide for the greatest amount of redundancy for your ASM data (you do not have advanced SAN mirroring technology available to you, unfortunately). Which of the following commands would create a disk group that would offer the maximum in data redundancy?

A.    CREATE DISKGROUP dg_alliance1 NORMAL REDUNDANCY failgroup diskcontrol1 DISK ,,
c:\oracle\asm_disk\_file_disk3 NAME file_ diska1 failgroup diskcontrol2 DISK ,,
c:\oracle\asm_disk\_file_disk4 NAME file_ diskb1;
B.    CREATE DISKGROUP dg_alliance1 EXTERNAL REDUNDANCY failgroup diskcontrol1 DISK
‘c:\oracle\asm_disk\_file_disk3’ NAME file_ diska1;
C.    CREATE DISKGROUP dg_alliance1 HIGH REDUNDANCY failgroup diskcontrol1 DISK
‘c:\oracle\asm_disk\_file_disk1’ NAME file_ disk1 failgroup diskcontrol2 DISK ‘
c:\oracle\asm_disk\_file_disk2’ NAME file_ disk2 failgroup diskcontrol2 DISK ‘
c:\oracle\asm_disk\_file_disk3’ NAME file_ disk3;
D.    CREATE DISKGROUP dg_alliance1 MAXIMUM REDUNDANCY failgroup diskcontrol1 DISK
‘c:\oracle\asm_disk\_file_disk1’ NAME file_ disk1 failgroup diskcontrol2 DISK ‘
c:\oracle\asm_disk\_file_disk2’ NAME file_ disk2 failgroup diskcontrol2 DISK ‘
