Consider the fiollowing sequence ofi CELLCLI commands and SQL statements:

All CELLCLI commands and SQL statements are executed successfiully without warnings.
Which statement is true about the I/O perfiormance ofi the DATA01 ASM diskgroups?

A. The DATA02 ASM diskgroup has better perfiormance because the DATA02 diskgroups was created first. B. The perfiormance ofi both diskgroups is balanced because they are created on interleaved griddisks. C. The DATA01 diskgroup has better perfiormance because the DATA01 griddisks are created on interleaved cell disks. D. The DATA01 diskgroups has better perfiormance because the DATA01 griddisks were created first.

QUESTION NO: 5
You have two very large databases supporting OLTP workloads which run on multiple small-blade style servers in a
cluster and which require optimal latency fior I/O.
You plan to migrate them to a Database Machine once a capacity planning exercise is finished.

High availability requirements state that you must be able to survive node fiailures at any time.
Which three Database Machine components or fieatures would you recommend to support these requirements?

A. High perfiormance disks in the Database Machine B. High capacity disks in the Database Machine C. A high perfiormance expansion fiull rack D. Use ofi smart flash logs E. Use ofi write back flash cache F. A high capacity expansion fiull rack

Correct Answer: B,D,E
