正解：C

質問 2：
An Administrator is concerned that a VM on a hybrid Cluster with 8Gb RAM and 4 vCPU is performing poorly.
An Analysis of the VM indicates that CPU Utilization is at 50% ,memory utilization is at 30% , and disk latency is at 18ms.
What can the administrator do to improve performance?
A. add 4GB RAM
B. Enable FLash Mode
C. Increase vDisk Size
正解：A

質問 3：
An administrator is managing two AHV and vSphere-Based Clusters. The administrator is able to install a Windows Guest OS from an ISO Image to VMWare VMs , but is unable to do the same activity with AHV VMs.
What should the administrator do to successfully perform this action with AHV VMs?
A. Manag Nutanix Guest tools
B. Verify cluster iSCSI data Services IP
C. Provide virtIO Drivers
D. Change VM Setting From BIOS to UEFI
正解：C

質問 4：
A VDI environment based on AHV Cluster is not performing well. The current environment is using only one bridge (Bridge0). The administrator needs to verify if nodes are using all network cards associated to Bridge0.
Which two menus should be used to check the current configuration? (Choose two.)
A. Host NICs tab in Hardware menu
B. Network Configuration item in Settings menu
C. Host view in Network menu
D. I/O Metrics tab in VM menu
正解：A,C

質問 5：
Refer to the exhibit.

A Nutanix host is connected as shown in the exhibit with br0-up set to active/backup. Physical Switch 1 experiences a power outage causing br0-up to failover to using eth2. The CVM and host become inaccessible. User VMs restart on other hosts in the cluster, which causes a disruption to those VMs.
Which configuration issue likely caused this outage?
A. Bridge br0-up should be configured to use balance-tcp rather than active/backup.
B. The upstream port for eth2 is missing a VLAN.
C. The CVM should have eth1 connected to the OVS.
D. The user VMs only have one NIC
正解：B

質問 6：
Over the period of 2 to 3 weeks, a cluster displays the following:
* Periods where Warning Alerts of memory usage over 75% are asserted
* Periods where Critical Warnings of memory usage over 90% are asserted
* Periods of slow of frozen VDI desktops have caused work stoppage or slowdown
* VDI clones have periodically not powered up when called, causing work stoppage Which steps should be used to prioritize the administrator's troubleshooting efforts?
A. * Assess resource health on Hardware page
* Review the Analysis page for memory usage demand
* Determine the VDI workload-to-host affinity across the cluster
B. * Analyze Alert Pages for a root cause of memory problem
* Analyze VM table page to access the VM functionality
* Analyze the VDI Clone properties for possible VDI Workload stress
C. * Review Analysis Page for memory use pattern
* Alert with VDI workload demand
* Analyze current and future workload in the Capacity Runaway tab for sufficient resources
D. * Check Analysis page for CPU demand
* Verify VDI workload property for memory subscription
* Review the Hardware page to determine if the cluster has sufficient RAM
正解：C

質問 7：
An administrator responsible for a VDI environment needs to investigate reports of slow logins. The administrator finds that increasing the number of vCPUs from 2 to 4 will reduce the login times. Production workloads are consuming 75% of the host CPU on the cluster. The administrator increases the vCPU count on all of the VDI VMs.
What are two impacts on the cluster? (Choose two.)
A. Increase CPU utilization%
B. Increase CPU ready%
C. Increasing CPU counts will decrease memory utilization
D. Increase memory utilization%
正解：C,D

質問 8：
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 performance test is generating small block random 10.
B. Data Locality ensures that VM attached disks are always faster than iSCSI volumes.
C. The duster data services IP address is a bottleneck, shared with other iSCSI traffic
D. The VM's iSCSI traffic is being routed to the data services IP subnet
正解：C
