Citrix Xendesktop Architecture Diagram

[Bartley Trowbridge]

WithXenDesktop 7.0 release, the new unified Citrix FlexCast management architecture combines VDI and hosted shared desktops and apps from a single platform. XenApp farms can now be deployed and managed within XenDesktop Studio. This also means XenApp servers can be provisioned using the Machine Creation Services linked-clone delivery model or with the better performance and better scalability PVS solution.

NetApp, Cisco and Citrix believe that mobile work styles, powered by the cloud, have transformed business and are spurring an architectural revolution in IT. We are working on reference architecture on FlexPod with XenDesktop and different hypervisors vSphere, Hyper-V and XenServer.

The solution architecture is, at its core, detailed in the FlexPod Deployment Guide. Connectivity remains the same, as are other component configurations. Diagram below shows our end to end infrastructure diagram.

Scenario: A Citrix Architect needs to assess a XenApp and XenDesktop environment. The XenApp and XenDesktop diagram in the Exhibit gives details about the current Site and Zone design.

Which statement is correct if all the Delivery Controllers in the Primary Zone fail?

Scenario: A Citrix Architect is designing a new, 2,000-user XenApp and XenDesktop environment. The environment will use Windows Server 2016 for all Site infrastructure components (Delivery Controllers, StoreFront servers, Provisioning Services servers, Citrix Director). Provisioning Services (PVS) will be used to provision Virtual Delivery Agent (VDA) machines. The environment will include two primary use cases:

-> Windows Server 2016 VDA machines providing hosted apps

-> Windows 10 VDA machines providing random, non-persistent VDI

Within the company there is existing hardware which is hosting non-Citrix workloads. The hardware, which is using a third party hypervisor, has some spare capacity, but NOT enough to support the entire XenApp and XenDesktop environment. As a result, the IT team is planning to purchase additional hardware to support the expected capacity but has NOT determined which hypervisor will be used for that hardware. The IT team would like to utilize the existing hardware and wants to minimize the long-term costs of the solution while still providing a good user experience.

How should the architect design the hypervisor resource pools based on Citrix leading practice?

Scenario: A Citrix Architect is investigating a recent change that is impacting system performance of the Provisioning Services farm. However, no actions have been recorded in the Audit Trail.

Which two processes are preventing Provisioning Services auditing from recording the actions? (Choose two.)

Scenario: A Citrix Architect needs to create a conceptual architecture for a XenApp and XenDesktop environment on behalf of a marketing firm. Based on some initial discussions around the firm's business goals and objectives, the architect has collected the information as shown in the Exhibit.

The architect should scale the hardware used to host the VMs for User Group 1 to______GB of RAM. (Choose the correct option to complete the sentence.)

Scenario: A Citrix Architect needs to design a new XenApp and XenDesktop environment. The customer previously installed all applications locally on managed laptops and desktops but is willing to evaluate other application delivery methods as part of the new deployment. The environment will be standardized on

Windows 10 and Windows Server 2016 for the Virtual Delivery Agent (VDA) machines.

As part of an application analysis performed earlier in the project, the information in the Exhibit was collected regarding one of the required applications.

Additionally, the customer has the following objectives:

-> Minimize the amount of additional infrastructure components.

-> Minimize the server hardware required.

How should the architect install the application?

Scenario: During an assessment of a Citrix Infrastructure, a Citrix Architect finds that there are four active Sites. Each Site has one NetScaler SDX pair and two

StoreFront servers in a server group to allow access for internal and external users. Users have to use different URLs when they access resources from different

Sites. Single-factor authentication is used for both internal and external access. NetScaler appliances are placed in the DMZ with the appropriate firewall ports configured to allow Citrix traffic. Many of the internal users connect using corporate-owned laptops and some external users also connect using personal devices.

The architect needs to provide a design for a multi-tier environment with segregated internal and external traffic on the NetScaler appliance.

How many NetScaler instances and StoreFront servers are required to meet this highly available design?

Scenario: A Citrix Architect is performing a XenApp and XenDesktop design. During a discussion with the server hardware team, two potential network configurations are proposed for the XenServer hosts.

Click the Exhibit button to view the network configurations.

Which statement will support a decision to use Network Configuration 2?

Scenario: A Citrix Architect is assessing a Provisioning Services farm. The farm has access to one Store; the vDisks in the Store are shown in the Exhibit.

Click the Exhibit button to view the vDisks.

How much RAM should the architect allocate to each of the Provisioning Services servers to optimally cache existing vDisk data while NOT over-provisioning resources?

Scenario: A Citrix Architect needs to create a conceptual architecture for a XenApp and XenDesktop environment, on behalf of a retail chain. Based on some initial discussions around the firm's business goals and objectives, the architect has collected the information as shown in the Exhibit.

Which delivery model should the architect recommend?

Scenario: While assessing User Layer, a Citrix Architect finds that most of the internal users connect using corporate-owned laptops, desktop devices, and thin clients. Many of these laptops and desktop devices are running Windows 10, while the remainder of the machines are running Windows 7 and are in the process of being migrated to Windows 10. Some users also connect using personal devices.

Currently, Citrix Receiver is manually installed on any endpoint device added to the company. All these devices use Citrix Receiver version 4.8 and above. The IT team is planning to automate a process to update all the devices with the latest version of Citrix Receiver and to automate another process for automatic installation of Citrix Receiver without incurring extra costs and maintenance.

The architect needs to identify which type of Citrix Receiver to recommend for 25 task workers in a remote location where installation of Citrix Receiver is NOT possible. The workers do NOT require any device mappings.

Which type of Citrix Receiver should the architect recommend?

Scenario: IT management has decided which server hardware model to use for new XenApp and XenDesktop Sites and needs guidance on sizing the Hardware

Layer.

A Citrix Architect is planning to install XenServer 7.x on this host.

How many vCPUs will be available to the XenServer host?

Virtual Desktop Infrastructure (VDI) is virtualization technology that hosts a desktop operating system and applications on a centralized server in a data center. This enables a complete, and personalized, desktop experience for users with a fully secured and compliant centralized source.

Teams also supports multiple configurations in virtual environments. These include VDI, dedicated, shared, persistent, and non-persistent modes. Features are in continuous development and are added on a regular basis, and functionality will expand over time.

Using Teams in a virtualized environment might be somewhat different from using Teams in a non-virtualized environment. For example, some advanced features might not be available in a virtualized environment, and video resolution might differ.

The Teams desktop app was validated with leading virtualization solution providers. With multiple market providers, we recommend that you consult your virtualization solution provider to ensure that you meet the minimum requirements.

Currently, Teams on VDI with audio/video (AV) optimization is certified with Azure Virtual Desktop, Citrix, and VMware. Review the information in this section to ensure that you meet all requirements for proper functionality.

SingleWindow UI mode is deprecated as of January 31st 2024 (see MC Post 674419). Citrix customers must upgrade the CWA/VDA to minimum versions that support MultiWindow, otherwise users will not be optimized.Minimum versions:

Citrix Virtual Apps and Desktops (formerly known as XenApp and XenDesktop) provides AV optimization for Teams on VDI. With Citrix Virtual Apps and Desktops, Teams on VDI supports calling and meeting functionality in addition to chat and collaboration.

You can download the latest version of Citrix Virtual Apps and Desktops at the Citrix downloads site. (You'll need to sign in first.) The necessary components are bundled into the Citrix Workspace app (CWA) and Virtual Delivery Agent (VDA) by default. You don't need to install any additional components or plugins on CWA or the VDA.
