Nutanix NCP-EUC Dumps

The Nutanix AHV MCS Plug-in is a tool that enables Citrix Virtual Apps and Desktops Delivery Controllers (also called Brokers) to create and manage Citrix-provisioned VMs in a Nutanix AHV infrastructure environment. The plug-in is based on the Citrix-defined plug-in framework2.

To install the Nutanix AHV MCS Plug-in, you need to meet some prerequisites, such as:

• The Delivery Controller version must be 7.15 LTSR CU3 or later.
• The Delivery Controller must be able to communicate with Prism Element (PE) using HTTPS port 9440.
• The Delivery Controller must have PowerShell 5.1 or later installed.
• The user running the installer must have administrator privileges on the Delivery Controller2.

Nutanix's Shadow Clones feature is used to create linked clones or snapshots of base VMs, which can improve VM provisioning time and storage efficiency by reducing the amount of duplicated data.

If an administrator disables Shadow Clones within a company's VDI environment, it is likely that deployment times would increase as the number of deployed desktops increases. This is because linked clones or snapshots would no longer be used, so each new desktop deployment would require creating a full copy of the base VM.

Nutanix Shadow Clones allow for distributed caching of a particular disk or VM data, which are in a ‘multi-reader’ scenario. This can help in scenarios such as VDI or private clone boot storms, where VMs on multiple nodes read from the same set of base disks12

one of the possible causes of slower logon and application load times for VMware Horizon-based virtual desktop users is Failed to create Native clone errors. This error occurs when there is a problem with cloning virtual machines using Nutanix Native Clones technology. To troubleshoot this issue, you can check the following:

• The Nutanix cluster has enough free space to create clones
• The Nutanix cluster has enough CPU and memory resources to handle cloning operations
• The Nutanix cluster is running a compatible version of AOS and AHV with VMware Horizon
• The VMware Horizon environment is configured correctly to use Nutanix Native Clones
• The VMware Horizon agent is installed and updated on the master image

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.

one of the factors that affects end-user performance in a virtual desktop environment is network latency, which is the time it takes for data packets to travel between two points on a network.

Therefore, if the company wants to optimize end-user performance, they should choose a public cloud data center location that minimizes the network latency between the end user and the data center.

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.

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.

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.

the delivery method in use is Citrix MCS. Citrix Machine Creation Services (MCS) is a technology that creates and manages virtual machines from a master image. MCS uses Nutanix storage efficiency features such as deduplication and shadow clones to reduce storage consumption and improve performance. The exhibit shows that the VDI cluster has a high deduplication ratio (7.5x) and a low physical space usage (1.2 TB) compared to the logical space usage (9.1 TB), which indicates that MCS is in use.

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.

The Public Network option provides access to the Frame environment over the public internet, while the Private Network with VPN option allows for a secure connection to the Frame environment over a private network using a VPN.

View Composer API for Array Integration (VCAI) is a feature of VMware Horizon that leverages the native cloning abilities in the storage array to offload storage operations within a VMware View environment12. This feature allows customers to offload the creation of linked clones to the storage array3.

In Nutanix Prism Central, the Capacity Runway scenario provides details on the available capacity for the next 12 months based on the current usage pattern. This feature can help the administrator to plan and prepare the budget for the next fiscal year. The administrator can use this information to decide whether more resources need to be added to the Nutanix cluster or if the existing resources are sufficient.

Prism Central planning tools can help you estimate the capacity runway of your cluster by considering the storage, CPU, and memory capacity. However, you need to have at least 21 days of data from a cluster to calculate the baseline runway estimates4.

an action that the administrator should take to enable Shadow Clones for a VMWare Horizon Solution on AHV is Connect to Prism Central and execute the cluster enable –cluster_cluster_uuid 0xxx – show_clones=true command. Shadow Clones are a feature that helps decrease read latency by creating local copies of frequently accessed data blocks on each host2. To enable Shadow Clones, the administrator needs to connect to Prism Central and run a cluster command with the appropriate parameters1.

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.

Nutanix offers a solution that delivers virtual apps and desktops in one click. Nutanix supports both persistent and non-persistent VDI deployments, as well as RDSH-based VMs and AppStacks.

Storage containers are logical units that group vDisks and apply storage policies such as replication factor, encryption, compression, deduplication and erasure coding3. Nutanix recommends using compression and deduplication to reduce storage usage and avoid duplicate data4.

 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.

Nutanix and Citrix provide a turnkey validated VDI infrastructure solution that allows 10x faster deployments, cuts management time by 70% and significantly reduces the number of support calls. Nutanix eliminates the complexity of managing discrete storage, servers and separate virtualization and networking stacks.

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

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.

Citrix NetScaler VPX is a virtual appliance that provides web and application load balancing, secure and remote access, acceleration, security and offload features1. To set up and configure a Citrix NetScaler VPX appliance, you need to download it from the Citrix website, install it on a hypervisor such as Citrix XenServer or Microsoft Azure23, and log on to the console using the nsroot credentials2.

To expose the Citrix NetScaler VPX private VIP to the internet in order for users to be able to access the Citrix VDI desktops upon a DR failover, one possible solution is to use a floating IP address. A floating IP address is an IP address that can be dynamically assigned to an instance by using API calls. It allows you to redirect network traffic from one instance to another without changing any DNS settings or client configuration.

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.
