Which two statements are true about initialization parameters for Clustered ASM instances?
A.
A change to ASM_DISKSTRING requires a restart of all ASM instances for the change to take effect.
B.
ASM_POWER_LIMIT controls the number of RDBMS instances that can access a disk group while it is being rebalanced.
C.
The ASM_DISKGROUP parameter is optional.
D.
The default value of INSTANT_TYPE is ASM.
E.
The maximum value of ASM_POWER_LIMIT is 1024.
Explanation:
C: The default value of the ASM_DISKGROUPS parameter is a NULL string. If the parameter value is NULL or is not specified, then ASM does not mount any diskhttp://www.gratisexam.com/
groups.
E: The ASM_POWER_LIMIT initialization parameter specifies the default power for disk rebalancing in a disk group. The range of values is 0 to 1024.
Incorrect Answers:
B: The ASM_POWER_LIMIT initialization parameter specifies the default power for disk rebalancing in a disk group. The range of values is 0 to 1024.
D: The default value of INSTANT_TYPE is RDBMS. https://docs.oracle.com/cd/E11882_01/server.112/e18951/asminst.htm#BHCEHJGA
The ASM_POWER_LIMIT initialization parameter specifies the
default power for disk rebalancing in the ASM instance Default is 1.
The default value is 1 and the range of allowable values is 0 to 1024
The INSTANCE_TYPE initialization parameter must be set to ASM for an ASM instance
MEMORY_TARGET specifies the total memory used by an ASM
instance.
If you want ASM to automatically mount the disk group when an ASM instance starts, you must add the disk group name to the value of the ASM_DISKGROUPS initialization parameter in your parameter files (PFILEs). If you use a server parameter file (SPFILE), the disk group is added to the initialization parameter automatically.
C,E CORRECT
I’m not sure about C, it can be nulled but is not the same as optional, is it?.
Yes, this is optional!
Why D not correct???
The default value of INSTANT_TYPE is ASM.

Today, in this Exam, the question appears like “The default value of INSTANCE_TYPE is ASM.”. In this case, “C”, “D” and “E” is correct! I choose “C” and “D”
Hi WGCM,
It is great to know that you have taken this exam. So when you choose C, and D. What is the final result for your mark?
The Exam doesn’t show if you are correct or wrong or in what question you are right, but in the final result, I passed in 2 sections but, i did not passed in RAC Administration (the third section)!
Hi WGCM,
You make me scare while you are so active but failed.
Did you retake WGCM?
They ask for questions that do not make any sense or that is not our day to day.
Many questions have complicated puzzles that confuse people and tend to make them to make a mistake, and the things you do constantly and are much more useful are completely ignored. Some issues are completely useless and relate to what Oracle already does automatically and we just need to have a sense of what happens. Our brain tends to ignore what is not going to be useful or so useful, so this is completely normal.
Many of these questions you will never see or work on in your life! In addition, we never work without manuals or consultations available in productive environments. This exam does not exist to prove that you know how to work with Oracle RAC, just to prove that you studied for the exam.
And for me there are still other problems, the average number of possible options per question is four options (and their combinations are incredible), this for 90 questions, in a limited time and in English, a question for me, my language Native is Portuguese, so my test is RAC and another language at the same time, in this case, English.
I’m taking in two weeks hope to pass it… I have now the other dump file 157 question…
Thanks for sharing your experience…
Can you share your experience?
I pick C and E.
I could not find reference to *default* instance_type in any documents. Yeah, INSTANCE_TYPE is ASM, but that is not default, that is the only choice. Unless you are talking about ASM proxy. Then again ASM proxy is not ASM.
usually default instance_type is rdbms. for asm instance, we need to set instance-type manually
IMO CE
It Should be “C” & “D”
I will go with D,E
E is totally correct. I have muy doubts with C.
Correct: C and E
E is not completelly right “For disk groups that have the disk group ASM compatibility set to less than 11.2.0.2, the operational range of values is 0 to 11 inclusive. If the value for ASM_POWER_LIMIT is larger than 11, a value of 11 is used for these disk groups”
