• Question 131:

  A shipping company tracks shipments and customer data using an Oracle 10g environment with ASM. There are several EMC VNX LUNs presented to Oracle. What ASM feature will help avoid hotpots?

  A. Spreads each file evenly across all disks within the disk group
  B. Automatically provisions storage pools for a VNX array
  C. Maintains database changes until it is written out to the redo log files on the disk
  D. A set memory structure and a number of system processes
  A. Spreads each file evenly across all disks within the disk group

• Question 132:

  A customer has two VNX systems:

  At the local site, a VNX capable of performing 20,000 LUN IOPS At the remote site, a VNX capable of performing 14,000 LUN IOPS

  At the local site, application LUNs to be mirrored to the remote site perform 2,000 random 4 kB IOPS, with a R/W ratio of 3:1. At the remote site, application LUNs to be mirrored to the local site perform 1,200 random 8 kB IOPS, with a R/W

  ratio of 2:1. The utilization of both systems must be 70% or lower.

  MirrorView/A will be used to replicate the data.

  How much throughput can be performed by other applications at the local and remote sites?

  A. Local: 9,600 IOPS; Remote: 5,600 IOPS
  B. Local: 16,800 IOPS; Remote: 10,800 IOPS
  C. Local: 12,000 IOPS; Remote: 8,600 IOPS
  D. Local: 18,000 IOPS; Remote: 12,800 IOPS
  A. Local: 9,600 IOPS; Remote: 5,600 IOPS

• Question 133:
