Question 4

You have a 4-node cluster with an AFF A300 HA pair and a FAS8200 HA pair. You plan on using the
default storage efficiency settings. With inline data compaction, you estimate that you can save 6% of
storage space. AFF A300 volumes that use under 5000 IOPS are moved to a FAS8200 using the
volume move command.
In this scenario, what happens to the data after the volume is moved? (Choose two.)

  • A. The new written data is not compacted.
  • B. The existing data is compacted.
  • C. The new written data is compacted.
  • D. The existing data is not compacted.

Question 5


You have a requirement to serve LUNs with under 200 microsecond latency using local server lass
memory. You also are required to use a shared SAN.

solution? (Choose two.)

  • A. iSCSI

Question 6

A company has 20 ESX hosts. Ten of the hosts are connected using FC, and the rest are connected
over iSCSI. The FC host HBA queue depth is set to 32, and the iSCSI LUN queue depth is set to 64. The
FC hosts are now experiencing random connectivity issues.
In this scenario, what would be the reason for the disconnects?

  • A. The FC host has a lower queue depth.
  • B. According to the IMT, unsupported HBA firmware is in use.
  • C. All of the hosts are part of the same cluster.
  • D. The queue depth is not consistent across the cluster.

Question 12

You have a thin-provisioned LUN that was created by using the lun create -vserver vs1 - path
/vol/vol1/lun1 -size 500G -ostype windows 2008 -space-reserve disabled -space-allocation disabled
command. You verify that your Windows 2016 host reports 200 GB free on lun1. However, lun1
shows 0 bytes free on the storage cluster.
What should you do to solve this problem?

  • A. Change the LUN -space-allocation parameter to enabled.
  • B. Change the LUN -ostype parameter to windows_gpt.
  • C. Change the LUN -space-reserve parameter to enabled.
