An administrator is migrating a legacy iSCSI solution to Volumes and needs to reconfigure the iSCSI initiator in the Windows client devices.
What should the administrator understand about the client-side iSCSI configuration?
- A. IP addresses of all CVMs should be entered.
- B. IP addresses of all FSVMs should be entered.
- C. The Enable mufti-path option should be unchecked.
- D. The Nutanix MPIO drivers should be installed.
正解：B
解説：
IP addresses of all FSVMs should be entered. FSVMs are File Server Virtual Machines that provide iSCSI services for Nutanix Volumes. The iSCSI initiator in Windows client devices should be configured with the IP addresses of all FSVMs in a cluster to enable load balancing and failover. The Enable multi-path option should be checked to use multiple paths for iSCSI traffic. The Nutanix MPIO drivers are not required for Windows clients as they can use native MPIO drivers.

質問 # 25
An administrator has received multiple trouble tickets from users who are unable to access a particular Distributed share.
While troubleshooting, the administrator observes that data located on FSVM 3 can be accessed, but the data located on FSVMs 1 and 2 is inaccessible. The administrator receives this message when attempting to access data on FSVMs 1 and 2:
Network object not found
Both FSVM 1 and 2 nodes successfully reply to pings, and the administrator is able to access data via the node IP.
What must the administrator check as a next step?
- A. Check if user permissions are configured correctly.
- B. Check if all DNS records are created on the DNS server.
- C. Check if keberos_time_skew is logged on the client.
- D. Check if SM3v1 is enabled on FSVM node 1 and 2.
正解：B
解説：
According to Nutanix Support & Insights1, a distributed share is a type of SMB share that distributes the hosting of top-level directories across FSVMs. To access a distributed share, you need to use a DNS name that resolves to all FSVMs in the cluster.
If some DNS records are missing or incorrect, then some FSVMs may not be reachable by their DNS name, resulting in the network object not found error. This could explain why data located on FSVM 3 can be accessed, but data located on FSVMs 1 and 2 is inaccessible.
質問 # 26
An administrator has mapped a Volume Group named VGI to a VM, Due to changes in the application running inside the VM, two additional volumes are required. At the time of creation, the VM was assigned to a Protection Domain named PDI.
Which two steps should the administrator take to add the additional volumes to the VM while maintaining data protection? (Choose two.)
- A. Add two additional vDisks to VG1.
- B. Manually update PD1 to include the newly created vDisks.
- C. Add the new vDisks to the same Consistency Group.
- D. Map the new vDisks as volumes to the VM.
正解：A、C
解説：
To add additional volumes to a VM that is mapped to a VG, you need to add more vDisks to that VG1. vDisks are virtual disks that reside on Storage Containers2.
To maintain data protection for a VM that is assigned to a Protection Domain (PD), you need to add any new vDisks to the same Consistency Group (CG) as the existing ones3. A CG is a subset of entities in a PD that are snapshotted in a crash-consistent manner2.

- D. Prism Element
正解：A
解説：
According to Nutanix Support & Insights1, Nutanix Files is a scale-out file storage solution that provides SMB and NFS file services to clients. Nutanix Files instances are composed of a set of VMs (called FSVMs) that run on Nutanix clusters.
According to Your Complete Guide to Nutanix Files Training Resources2, Prism Central is the interface used to deploy a new Files instance. Prism Central is a centralized management console that provides visibility and control across multiple Nutanix clusters and services.
質問 # 28
An administrator would like to convert an existing Volume Group with an attached external Windows client to use Volumes.
The administrator has taken these actions:
* Disconnect any existing iSCSI targets
* Remove targets from the Favorite Targets tab
* Remove targets from the Discovery tab
Which action must the administrator take next to complete this task?
- A. Connect with MPIO to the iSCSI Data Services IP.
- B. Connect without MPIO to the Cluster Virtual IP.
- C. Connect without MPIO to the iSCSI Data Services IP.
- D. Connect with MPIO to the Cluster Virtual IP.
正解：A
解説：
Connect with MPIO to the iSCSI Data Services IP. The iSCSI Data Services IP (DSIP) is a virtual IP address that provides load balancing and failover for iSCSI traffic across all CVMs in a cluster. The MPIO (Multi-Path I/O) option enables multiple paths for iSCSI traffic between Windows clients and Nutanix Volumes. The Cluster Virtual IP (CVIP) is used for management and communication between CVMs and should not be used for iSCSI traffic.

解説：
These steps are based on a guide from Nutanix on how to troubleshoot pre-upgrade checks failure for Nutanix Files1. The guide states that one possible cause of this error message is that Nutanix files node (fsvms) might not be up or accessible1. The guide also suggests checking if Zookeeper services are running on all FSVMs as part of the troubleshooting process1.
質問 # 37
What is the reason for the alert: File Server In Heterogeneous State?
- A. The FSVMs do not match in their CPU or memory
- B. The FSVMs are distributed properly on the hosts in the cluster.
- C. Performance of the File Server is optimal, and the alert can be ignored.
- D. The hosts where the FSVMs run do not match in their CPU or memory configuration
正解：A
解説：
According to the Nutanix Files Solution Guide1, all the FSVMs have the same basic configuration: four vCPU and 12 GB of RAM1. However, you can add more vCPU, RAM, and FSVMs to the cluster1.
Based on this information, the alert: File Server In Heterogeneous State indicates that the FSVMs do not match in their CPU or memory configuration1. This could affect the performance and availability of the file server
質問 # 38
In a Nutanix cluster based on AHV, multiple Nutanix unified Storage services such as Volumes, Files and Objects are deployed. After performing an LCM inventory, MSP is listed as an update.
Which storage service requires MSP to be updated?
- A. Prism
- B. Volumes
- C. Files
- D. Objects
正解：D
解説：
"Kubernetes is not correctly reporting its storage usage." The NCC checks run on the nodes in the cluster and may report storage usage differently based on how they are being executed. Additionally, the administrator notes that the Kubernetes pod reports that the usage is 55% used disk space, which is different than what the NCC checks report.
One possible cause of this discrepancy is that Kubernetes is not correctly reporting its storage usage. It is recommended that the administrator checks the Kubernetes storage configuration to ensure it is set up correctly and that Kubernetes is able to accurately report the storage usage. It may also be necessary to update or reinstall Kubernetes if there are any issues with the installation.
Nutanix Objects is a software-defined object storage solution that provides scalable and secure data storage for unstructured data1. MSP is responsible for routing requests from clients to Objects clusters and providing load balancing and high availability1. To update MSP, you need to perform an LCM inventory and select MSP from the software updates list1.
