Exam NS0-194 Topic 6 Question 63 Discussion

Actual exam question for Network Appliance's NS0-194 exam
Question #: 63
Topic #: 6

Your customer calls at 8:40 a.m. indicating that the performance of his FAS2240- 2 is very slow for all protocols used (NFS, FC, and SMB).
The customer explains that the day before, he migrated half of his virtual machines (VMs) onto new VMware VMFS data store LUNs in the same volume as his old VMFS data store LUNs.
What are two reasons for the customer's problem? (Choose two.)

A. After moving the VMs to different data stores, the deduplication jobs that started during the night are still running. This is causing high disk utilization, impacting overall performance. B. Moving the VMs to different data stores put their low read load VMs on slow disks. Because the read I/O for those VMs is slow, this is impacting consistency points on the controllers. C. After moving the VMs, they are now backed up as new data in that volume, causing the SnapVault relationships to still operate. This is overloading the disks and causing slow performance for all users. D. Moving the VMs elsewhere did not release the volume capacity used because of Snapshot copies. Now the volumes are too full and this will impact performance for all users.
