  A. deduplication

  B. compaction

  C. compression

  D. thin provisioning

  Correct Answer: B

• Question 185:

  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.

  D. Rescan the LUN disk in your Windows host so that it will notify NetApp about the free space.

  Correct Answer: D

• Question 186:

  You have a 2-node cluster in a single-fabric SAN. Host 1 and Host 2 are part of a VMware cluster and access the same LUNs that reside in your NetApp storage.

  Referring to the exhibit, what would be a way to test whether the multipathing is properly configured in your environment?

  A. Verify whether all destination storage target ports are contained in the same zone as Host 1.

  B. Administratively set ports 0a and 0c on Controller 1 to the offline setting.

  C. Power off the SAN switch.

  D. Disconnect Host 1 port and verify whether Host 2 is still able to run the VMs.

  Correct Answer: B
