質問 34
An administrator is deploying an application using Nutanix Volumes. After configuring the volume group and connecting the guest's iSCSI initiator to the volume group, they begin performance testing.
The administrator learns that performance on the virtual disk attached to the iSCSI initiator is far less than that of a virtual disk connected directly to the VM.
Which situation is causing this condition?
- A. The VM's iSCSI traffic is being routed to the data services IP subnet
- B. Data Locality ensures that VM attached disks are always faster than iSCSI volumes.
- C. The performance test is generating small block random 10.
- D. The duster data services IP address is a bottleneck, shared with other iSCSI traffic
正解: D
質問 35
