Which two may act as building blocks for the creation of two or more griddisks residing on the
same physical device and which have more balanced performance characteristics?
A.
griddisk on hard drive-based intervleaved celldisks.
B.
griddisk on hard drive-based celldisks consumed by ASM when creating diskgroups using
ASM-based intelligent Data Placement (IDP)
C.
griddisk on hard drive-based non-interleaved celldisks.
D.
griddisk on Flash-base celldisks.
Explanation:
A (not C):Interleaved Griddisks mean equally fast Griddisks, whereas with non
Interleaved Griddisks (the default) the Griddisks created first are being taken from the outer tracks
of the underlying physical disk.
B:Intelligent Data Placement, a feature of ASM that allows placing data in such a way that more
frequently accessed data is located close to the periphery of the disk where the access is faster.
correct answer should be D instead of B because question has mentioned “balanced performance characteristics” which could be achieved by flash based disk.
B looks correct
A & B are correct. Question focuses on balanced performance not fast. Interleave structure is all about balanced performance of grid disks.
A & D are correct donkeys
Correct answers: A,D
a b
I agree. A B
Correct answer is A,D
I vote A & D
A and D.
A is right. Interleaved celldisks provide mixed sections for balanced performance
B is wrong. IDP is to provide different performance attributes, e.g. HOT, COLD
C is wrong. non-interleaved celldisks are not performance balanced.
D is right. Flash-based celldisks are equal performed.
So A.D. are correct.
It’s talking about same physical disk device so A,D must be true.
A and D
B is wrong as IDP is to provide different performance attributes, e.g. HOT, COLD as L Zhu mentioned above
AD
Cleared the 1Z0-027 exam several days ago!
Scored 87% for the second try! (The passing score is 60%.)
Total 90 questions, they are mainly on Exadata Database Machine, ILOM, RMAN, I/O resource, CellCLI (commands), OLTP…etc.
I used the latest version PassLeader 107q dumps (here it is: http://www.passleader.com/1z0-027.html)
Almost all questions were from it, and some wrong answers have been corrected in that PL 107q dumps, the most valid 1Z0-027 dumps!
By the way, part of that 107q PassLeader 1Z0-027 dumps are available on Google Drive for free:
https://drive.google.com/open?id=0B-ob6L_QjGLpZ05EYlhnaTd2VGs
(It seems that PL just updated that 107q files…)
Good Luck!!!
