NCP-EUC Nutanix Certified Professional - End User Computing (NCP-EUC) v6.5Exam Questions and Answers

Nutanix Frame has several session settings that can affect the user experience and resource utilization. One of these settings is Max session duration, which defines how long a user can stay connected to a Frame session before it is automatically terminated1. If this setting is too low, users might experience random disconnections and lose their applications and files.Therefore, the configuration setting that must be modified in order to resolve this issue is A (Max session duration).

Based on the given information, the administrator is deploying 1000 instant clone virtual desktops, 500 full clone virtual desktops, and 150 applications. To support these workloads, the Nutanix solution will need multiple storage containers.

According to the Nutanix Certified Professional - End User Computing (NCP-EUC) v6 guide, for VDI workloads, it is recommended to create a separate storage container for each type of desktop (e.g. instant clone, full clone) and another container for AppStacks. It is also recommended to have at least one container for metadata and one container for replicas.

Therefore, for this scenario, a total of 3 storage containers should be created:

• One container for 1000 instant clone virtual desktops
• One container for 500 full clone virtual desktops
• One container for 150 applications delivered via AppStacks

So the answer is C. 3.

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.

gold image is a term used to describe a template for a virtual machine (VM) that contains a preconfigured operating system and applications1. A gold image can be used to create multiple session hosts that share the same configuration1. However, a gold image needs to be properly prepared before being used as a template123.

One of the steps involved in preparing a gold image is to run sysprep on the VM. Sysprep is a tool that removes system-specific data such as computer name, security identifier (SID), and driver cache from Windows23. This allows the VM to be generalized and duplicated without causing conflicts or errors23.

One of the options that can be set when running sysprep is CopyProfile. CopyProfile is a setting that determines whether the user profile settings of the built-in administrator account are copied to the default user profile2. The default user profile is used as a template for creating new user profiles on Windows2. If CopyProfile is set to True, then any changes made by the administrator account (such as desktop wallpaper, screen saver, Start menu items, etc.) will be applied to all new user profiles2.

Therefore, if users are being disconnected from their sessions consistently after 10 minutes, it could be because the gold image has some incorrect settings in the default user profile that cause session timeout or termination. To resolve this issue, one possible solution is to sysprep the gold image with CopyProfile set to True, and make sure that there are no settings in the administrator account that could affect session stability (such as power saving options or Windows Store applications)2.

Frame is a cloud-native desktop-as-a-service platform that delivers virtual apps and desktops from multiple public clouds1. Frame allows administrators to manage various components of their cloud accounts easily from the Frame console1.

A cloud account is a logical grouping of resources that are associated with a specific cloud provider (such as AWS, Azure, or Google) and region1. A cloud account can have multiple virtual networks, master images, and instance types that can be used to create and run virtual apps and desktops1.

To configure AWS, Azure, and Google accounts within Frame, an administrator needs to go to the Cloud Accounts section of the Frame console1. There, the administrator can add new cloud accounts or edit existing ones by providing the required credentials and settings for each cloud provider12.

Nutanix is the only vendor that supports replication of linked clones. This means that option A is correct. However, I cannot guarantee the accuracy or validity of this information, so please verify it with other sources before using it.

According to Nutanix documentation, to use more than two monitors with Frame, you need to deploy the Frame App. The Frame App provides multi-monitor support, whereas using Frame through web browsers is currently limited to two monitors.

Frame App is a native application that provides a better user experience for accessing Frame desktops and applications than a web browser1. Frame App supports the Frame multi-monitor feature automatically. If an end user has more than one monitor attached to their device, Frame App prompts the user if they want to use all of their monitors1. Frame Administrators do not have to enable explicitly multi-monitor support for Frame App users1.

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 self-service access to their apps and desktops through a web portal or native receiver.

regarding replicating AppStacks between Nutanix clusters, it is likely that the correct answer would involve configuring some form of replication or disaster recovery technology on the Nutanix clusters themselves.

administrator can take to resolve the issue of performance for several full clone virtual desktops within Cluster01 by migrating them to Cluster02. 

a recovery plan is a set of steps that defines how to recover guest VMs from a disaster. A recovery plan can be used to migrate VMs between Nutanix clusters at the same or different availability zones1.

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.

Deduplication is a process that eliminates duplicate data blocks and reduces the amount of storage space required for virtual desktops. Deduplication can be enabled at both cluster level and container level on Nutanix.

Deduplication can also work with VCAI (View Composer Array Integration), which is a feature that uses Nutanix native NFS snapshot technology to clone VMs2. VCAI can improve performance and reduce storage consumption for linked-clone desktop pools.

Another feature that can help with capacity issue is Shadow Clones, which is a distributed caching mechanism that allows multiple VMs to read from a single vDisk copy stored locally on each node3. Shadow Clones can reduce network traffic and improve boot times for virtual desktops.

Storage Efficiency features that will provide better storage efficiency and performance improvement for a mix of full clones and non-persistent desktops deployed via Citrix MCS on a three-node cluster are Compression and Deduplication. Compression is a technology that reduces the size of data blocks by removing redundant information. Deduplication is a technology that eliminates duplicate blocks of data and reduces storage consumption. Both Compression and Deduplication can be enabled on a per-container basis and can provide significant savings for Citrix virtual desktop deployments that use cloning technologies such as MCS2.

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.

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.
