Question No. 1

An administrator responsible for a VDl 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 VDl VMs.

What are two impacts on the cluster? (Choose two)

Show Answer Hide Answer
Correct Answer: C, D

According to the web search results, the two impacts on the cluster that will result from increasing the vCPU count on all of the VDI VMs are:

Increase CPU utilization%: CPU utilization is the percentage of time that a CPU is busy executing instructions5.By increasing the vCPU count on all of the VDI VMs, the administrator will increase the demand for CPU resources on the cluster, which will increase the CPU utilization percentage6.

Increase CPU ready%: CPU ready is the percentage of time that a vCPU is ready to run but is waiting for a physical CPU to become available5.By increasing the vCPU count on all of the VDI VMs, the administrator will increase the contention for physical CPU resources on the cluster, which will increase the CPU ready percentage6.A high CPU ready percentage can indicate performance issues such as latency or slowdowns5.


Question No. 2

An administrator needs to relocate an AHV cluster to a new datacenter during a maintenance window. The cluster will use the same IPs in the new datacenter.

Which two steps should be taken to prepare for this task? (Choose two.)

Show Answer Hide Answer
Correct Answer: B, D

According to the web search results, two steps that should be taken to prepare for relocating an AHV cluster to a new datacenter during a maintenance window are:

Shut down all user VMs in the cluster: This step is necessary to ensure that there is no data loss or corruption during the relocation process.The user VMs can be shut down either individually or in bulk by using the Prism Element web console or the acli command-line interface1.

Stop all Nutanix Files clusters: If the AHV cluster hosts any Nutanix Files clusters, they should be stopped before relocating the cluster. Nutanix Files clusters are composed of one or more virtual machines that provide file services to clients.Stopping a Nutanix Files cluster will stop all the file server VMs and release the resources they consume2.The Nutanix Files clusters can be stopped by using the Prism Element web console or the ncli command-line interface3.


Question No. 3

An administrator is commissioning a Nutanix Enterprise Cloud. Once the user VMs have been deployed and are running, the administrator finds that VMs on the same host are able to communicate, but are unable to communicate between hosts.

What must be changed to enable full inter-VM communications?

Show Answer Hide Answer
Correct Answer: C

According to the web search results, one possible cause of inter-VM communication failure between hosts is that the switch is not configured to allow VLAN 15 traffic. VLAN 15 is the default VLAN ID used by AHV for internal communication between CVMs and hosts.If the switch blocks or drops VLAN 15 packets, it will prevent inter-VM communication across hosts4. To enable full inter-VM communication, the administrator should update the switch to specifically allow VLAN 15 traffic on the ports connected to the AHV hosts.


Question No. 4

An administrator has a Custom backup application that requires a 2TB disk and runs m Windows. Throughput is considerably lower than expected.

The application was installed on a VM with the following configuration:

* FOU vCPUs with one core/vCPU

* 4GB of Memory

* One 50GB vDisk for the Windows installation

* One 2TB vDisk for the application

What is the recommended configuration change to improve throughput?

Show Answer Hide Answer
Correct Answer: C

According to the web search results, one recommended configuration change to improve throughput for a custom backup application that requires a 2TB disk and runs on Windows is to span the 2TB disk across four vDisks. Spanning is a technique that allows you to create a single logical disk from multiple physical disks.Spanning can improve throughput by distributing I/O requests across multiple disks and reducing contention5. To span a disk across four vDisks, the administrator should create four vDisks of equal size (500 GB each) and attach them to the VM.Then, in Windows Disk Management, create a spanned volume from the four vDisks and format it as NTFS6.


Question No. 5

An administrator is implementing a VDI solution. The workload will be a series of persistent desktops in a dedicated storage container within a four-node cluster Storage optimizations should be set on the dedicated storage container to give optimal performance including during a node failure event

Which storage optimizations should the administrator set to meet the requirements?

Show Answer Hide Answer
Correct Answer: D

According to the web search results, three storage optimizations that should be set on a dedicated storage container for a VDI solution with persistent desktops are compression, deduplication and erasure coding. Compression is a technique that reduces the size of data by removing redundant information. Deduplication is a technique that eliminates duplicate copies of data blocks and stores only unique blocks.Erasure coding is a technique that increases usable capacity by reducing the replication factor of data blocks and using parity information instead7.These three optimizations can improve performance and save storage space for VDI workloads, especially during a node failure event when data needs to be rebuilt from parity information8.The administrator can enable these optimizations by using Prism Element web console or ncli command-line interface9.
