NCP-EUC Exam Dumps - Nutanix Certified Professional (NCP) Questions and Answers

gpumodeswitch is a command-line tool that is used to switch supported NVIDIA GPUs between compute and graphics mode. Compute mode allows multiple VMs to share a GPU for CUDA workloads. Graphics mode allows a single VM to use a GPU for graphics workloads12. 

an action that the administrator should take to identify the virtual desktops in the environment that are using the most resources and causing resource contention is Filter the virtual desktops by Constrained: High. Constrained is a metric that indicates how often a virtual machine is unable to get its requested CPU resources. A high value means that the virtual machine is frequently starved for CPU and may experience performance degradation. By filtering the virtual desktops by Constrained: High, the administrator can see which ones are suffering from resource contention and take appropriate actions such as migrating them to less loaded hosts or increasing their CPU allocation.

Shadow Clones are a feature of the AOS storage that enables distributed caching of virtual disks (vDisks) that are read by multiple VMs on different nodes. This can improve performance and reduce network traffic in scenarios such as VDI deployments.

Therefore, if Shadow Clones were disabled, it could cause delays in the deployments of VD’ desktops, as they would have to read the vDisk from a remote node instead of a local cache.

Nutanix AHV Plug-In for Citrix Director provides more information on Citrix generated desktops running on Nutanix AHV. Some of the metrics that are available in customized reports are:

• VM CPU Usage
• VM Memory Usage
• VM Disk IOPS
• VM Disk Bandwidth

non-persistent VDI is a type of virtual desktop infrastructure (VDI) that does not save any changes made by the user on the virtual machine (VM) across sessions. Non-persistent VDI uses a master image to create and delete VMs as needed.

Therefore, if the administrator needs to manage a non-persistent deployment, they should avoid any requirements that involve modifying or installing applications on the VMs, as those changes would not be saved.

Frame is a cloud-based desktop-as-a-service platform that allows users to access Windows applications and desktops from any device1. A license server is a server that hosts a network licensing manager for software that requires licenses to run2. Frame supports using a utility server as a license server for Frame desktops1. A utility server is a stand-alone, general purpose Windows server that can be configured and managed from the Frame dashboard1.

This is because this option will enable the administrator to add a Nutanix cluster as a new connection by installing and registering the plugin on the Delivery Controllers that manage the connection type menu.

alert policies are rules that define the conditions for generating alerts on Nutanix clusters1. You can create custom alert policies based on your specific needs and preferences2Playbooks are automated workflows that perform actions based on triggers such as alerts3. You can create playbooks using predefined alerts or alerts matching criteria3.

To ensure that the vice president of IT infrastructure has the best possible experience and to be notified if any CPU resource constraints on the virtual desktop, one possible solution is to create a new alert policy to alert if the CPU on the virtual desktop is over a certain threshold (for example, 80%) and configure a playbook to send a notification (forexample, via email or Slack) to the administrator23. This way, the administrator can monitor the performance of the virtual desktop and take appropriate actions if needed.

The schedule has two rows: one for Weekdays and one for Tuesday and Thursday.

Each row has a column for Instances, which indicates how many instances should be running during that time range.

Each row also has a column for Time Range, which indicates the start and end time for running the instances.

The time range is expressed in 24-hour format, where 00:00 means midnight and 24:00 means midnight of the next day.

According to the exhibit, the schedule Dev has the following settings:

• On Weekdays (Monday to Friday), five instances are running from 09:00 am till 05:00 pm.
• On Tuesday and Thursday, five instances are running from 00:00 am till 24:00 pm.

The Prism Central Playbook Action is a tool that allows you to automate tasks based on triggers, such as events, alerts, or webhooks. You can define a series of actions (called a playbook) that perform operations on your infrastructure, such as adding or reducing resources on a VM2.

To use the Playbook Action for VMs, you need to meet some prerequisites, such as:

• The Prism Central version must be 2020.11 or later.
• The AOS version must be 5.15 LTSR or later.
• The hypervisor must be AHV or ESXi.
• The VMs must have Nutanix Guest Tools (NGT) installed and enabled3.

One of the possible reasons why the Playbook Action is no longer being triggered is that the virtual desktop CPU Usage alerts were not cleared. According to the Prism Central guide3, “If an alert has been triggered once and has not been cleared yet, then it will not trigger any action again until it has been cleared”. Therefore, if the CPU Usage alert remains active for a virtual desktop, it will prevent the Playbook Action from adding more vCPUs to it.
