Nutanix NCP-EUC Practice Test - Questions Answers, Page 5

A high CPU Ready time means that the vCPU is waiting too long for the pCPU, which can result in poor performance and slow responsiveness of the virtual machine (VM).

According to Nutanix best practices2, one of the factors that can affect CPU Ready time is the host power policy. The host power policy determines how aggressively the host will try to save power by reducing the frequency or voltage of the pCPUs.

The recommended host power policy for Nutanix clusters is High Performance, which disables any power saving features and ensures that the pCPUs run at their maximum frequency and voltage.

This answer seems to explain why desktops on one host are running slower and have higher CPU Ready times than on other hosts, as they may be suffering from reduced pCPU performance due to a lower host power policy.

The CPU usage percentage indicates how much of the allocated CPU resources the virtual desktop is consuming.

A high CPU usage percentage means that the virtual desktop is using a lot of CPU resources, which can affect the performance of other virtual desktops on the same host or cluster.

According to Nutanix best practices, the recommended CPU usage percentage for virtual desktops is less than 80%.

VM-0001 (99%)

VM-0002 (98%)

VM-0003 (97%)

VM-0004 (96%)

VM-0005 (95%)

VM-0010 (85%)

VM-0016 (81%)

These virtual desktops are likely contributing to the performance issue by consuming too much CPU resources and starving other virtual desktops from performing adequately.

This means that users can customize their virtual desktops with their own applications, settings, and data, and have them available every time they log on.

Persistent virtual desktops are suitable for users who need a consistent and personalized experience, such as developers.

According to Nutanix best practices2, one of the recommended migration paths for persistent virtual desktops is to convert the physical computers to virtual desktops.

This can be done by using a tool such as VMware Converter or Microsoft Disk2vhd to create a virtual disk image of the physical computer’s hard drive.

Then, this image can be imported into Nutanix Cloud Platform and used as a base image for creating persistent virtual desktops.

This migration path can preserve the existing applications, settings, and data of the physical computers and minimize the disruption for the users.

Citrix Workspace includes several components that can replace or integrate with the traditional Citrix infrastructure components, such as:

Citrix Cloud Services, which provide management and orchestration capabilities for Citrix Workspace, such as Citrix Virtual Apps and Desktops service, Citrix Gateway service, Citrix Endpoint Management service, etc.

Citrix Workspace app, which is a client software that enables users to access their apps and desktops from any device.

Citrix Cloud Connectors, which are software agents that establish a secure connection between Citrix Cloud Services and the on-premises or cloud-based resources, such as Active Directory, hypervisors, VDAs, etc.

According to Citrix documentation2, an administrator who chooses to move all of the backend Citrix infrastructure to be managed as a service by Citrix can use the following components:

Citrix Virtual Apps and Desktops service, which replaces the Citrix Delivery Controllers and provides centralized management and delivery of virtual apps and desktops.

Citrix Studio, which is still available as a web-based console for configuring and managing the virtual apps and desktops environment.

Citrix Gateway service, which replaces the Citrix NetScaler and provides secure remote access to virtual apps and desktops through a single URL.

Citrix StoreFront, which is still available as an optional component for providing users with selfservice access to their apps and desktops through a web portal or native receiver.

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.

One of them is Nutanix Frame, which is a cloud-based service that delivers virtual apps and desktops from any cloud provider or on-premises datacenter.

Nutanix Frame simplifies VDI deployment by providing automated cloud resource orchestration, user session brokering, and environment administration.

Another solution is Nutanix Citrix Cloud, which is a hybrid cloud solution that integrates Nutanix HCI with Citrix Virtual Apps and Desktops service.

Nutanix Citrix Cloud enables VDI deployment by providing centralized management and delivery of virtual apps and desktops through Citrix Cloud Services.

According to Nutanix best practices2, one of the steps needed for deploying VDI with Nutanix Citrix Cloud is to configure the PE Citrix Connection.

This step involves creating a connection between the Nutanix Prism Element (PE) cluster and the Citrix Cloud account, which allows Nutanix to register as a resource location for Citrix Cloud Services.

This connection also enables Nutanix to provide performance metrics, alerts, and actions for the virtual apps and desktops running on Nutanix HCI.

Nutanix Frame allows administrators to configure capacity settings for their virtual machines (VMs) that run virtual apps and desktops.

Capacity settings include:

Default capacity, which defines how many VMs are turned on when there is no user activity on the account. This setting helps reduce costs by turning off unused VMs.

Active capacity, which defines how many VMs are turned on when there is user activity on the account. This setting helps improve performance by ensuring enough VMs are available for user sessions.

Quick Publish, which defines how many VMs are updated with the latest changes when publishing a new version of an app or desktop. This setting helps speed up the publishing process by updating only a subset of VMs instead of all of them.

According to Nutanix Frame documentation1, Quick Publish value should be equal to or less than the active capacity value for each instance type.

If Quick Publish value is set higher than active capacity value, then Frame will ignore Quick Publish value and perform regular publishing instead.

Nutanix Files offers a feature called Smart DR, which enables share-level replication between active file server instances for disaster recovery.

Smart DR allows administrators to configure replication policies for each share, such as replication interval, retention period, and bandwidth limit.

Smart DR also supports failover and failback operations between source and target file servers in case of a disaster.

According to Nutanix best practices1, Smart DR is suitable for scenarios where users need to access their files from different locations or data centers.

Frame utility server is a stand-alone, general purpose Windows server that can be helpful for a variety of use cases, including:

License server: Install a network licensing manager for your software on a Frame utility server. Your production instances can then connect to this server to get the licenses.

Backend for a client-server application: Install a database or other backend service on a Frame utility server. Your production instances can then connect to this server to run your client-server application.

Shared file server: Install a file sharing service on a Frame utility server. Your production instances can then access shared files from this server.

Test and develop virtual desktops: Use a Frame utility server as a sandbox environment to test and develop your virtual desktops before publishing them to your production account.
