質問 3：
You must complete three steps.
Step 1:
SQL > CREATE DISKGROUP OCR_VOTE NORMAL REDUNDANCY
FILEGROUP controller01 DISK '/dev/asm_ocr_vote1'
FILEGROUP controller02 DISK '/dev/asm_ocr_vote2'
FILEGROUP controller03 DISK '/dev/asm_ocr_vote3'
ATTRIBUTE
'au_size' = '1M'
'compatible.asm' = '12.1';
Diskgroup created.
Step 2:
Step 3:
crsct1 query c@s votedisk

Which command is required for step 2?
A. crsctl replace <source_location> +OCR_VOTE
B. crsctl replace +OCR_VOTE
C. crsctl replace votedisk +OCR_VOTE

正解：C

質問 4：
You have completed a rolling conversion fromDNS to GNScluster resolution from the database andcluster resources end.The remaining are the configuration changes to be done from theclient side.
Which two items need to betaken into account to achieve a successful connection?
A. There is no need to change anything in client configuration as the combination of TAF and ONSwillautomatically take care of reaching the correct nodes
B. For each client using a SCAN, change the SCAN theclient uses so that theclient uses the SCAN in the domain delegated to GNS
C. All the nodes in the cluster need to be bounced oneafter the otherinorder for the changes to be completed as it is not possible to do it online
D. For each client using VIP names, change the VIP name on eachclient sothat they use the same server VIP name, but with the domain namein thedomain delegated to GNS.
正解：B,D

質問 5：
What device path do you have to specify in ASM, if you want to use the multipath device?
/dev/sdd = first path
/dev/sdd = second path
/dev/multipatha = path of the multipath OS driver
A. Only /dev/multipatha is enough.
B. /dev/sdc as disk group and /dev/sdd as failure group.
C. Only /dev/sdc is enough, because asmlib knows it is a multipath device.
D. You need to specify all the three devices and only then ASM will know this is a multipath device.
正解：A

質問 6：
The DISK_REPAIR_TIME attribute has expired after a transient disk error. What happens next?
A. Oracle ASM drops the disk.
B. Nothing, it was only a warning. All the disks are OK
C. This means that the disk is repaired and is put backinthe ASM disk group.
D. This means that Oracle will use ASM Fast Mirror Resync to sync the rest of the disks.
正解：A
