Q241. Which Horizon Agent for Linux installation parameter enables support for multi-session published desktops and applications?

1. –ipv6
   2. –multiple-session
   3. -S no
   4. –no-hosted-app

Correct Answer: 2. –multiple-session

Explanation: The –multiple-session option prepares a Linux machine for use in Horizon multi-session published desktop and application environments. It is required when a Linux machine will participate in an automated instant-clone farm supporting published desktops or applications. For a manual Linux farm, Omnissa documents using –multiple-session together with the unmanaged-agent setting -M no. The –ipv6 option enables IPv6 support, while -S no disables single sign-on installation. The –no-hosted-app parameter disables support for single-session hosted applications and therefore does not enable the required multi-session functionality.

Q242. An administrator is preparing a Linux machine for a manual multi-session Horizon farm. Which installation combination is appropriate?

1. –ipv6 -S no
   2. -T yes -U yes
   3. –multiple-session -M no
   4. –no-hosted-app -R

Correct Answer: 3. –multiple-session -M no

Explanation: For a Linux machine that will participate in a manual multi-session farm, Horizon Agent must be configured for both multi-session operation and unmanaged mode. Omnissa documents the combination –multiple-session -M no for this purpose. The multi-session option enables published desktop and application support, while -M no identifies the machine as unmanaged rather than as part of an automated instant-clone lifecycle. Other parameters control IPv6, True SSO, USB, registration, or hosted-application support. Using the correct installation mode is essential because manual farms and automated instant-clone farms have different lifecycle-management behavior.

Q243. What is a key limitation of a manual Linux desktop pool compared with an automated pool?

1. Horizon does not manage the lifecycle of the desktops in the manual pool
   2. Manual pools cannot contain vSphere virtual machines
   3. Horizon Agent cannot be installed on manual-pool machines
   4. Manual pools require instant-clone technology

Correct Answer: 1. Horizon does not manage the lifecycle of the desktops in the manual pool

Explanation: Manual Linux desktop pools contain machines that already exist before being added to Horizon. Horizon can broker access to these machines, but it does not create, replace, or otherwise manage their lifecycle in the same way it does with automated pools. Administrators must create and maintain the machines separately. Manual pools can include supported vSphere virtual machines, and Horizon Agent must be installed on those machines before they are added to the pool. Instant-clone technology is specifically not applicable to manual desktop pools. This distinction is important when deciding whether centralized automated provisioning or administrator-managed existing machines better fit the deployment.

Q244. Which statement correctly describes Linux instant-clone desktops in Horizon?

1. Every clone requires a completely independent full copy of the source disk
   2. They can only be created as manual desktop pools
   3. Horizon cannot use vCenter Server for Linux clones
   4. They share underlying virtual-disk resources, reducing storage consumption

Correct Answer: 4. They share underlying virtual-disk resources, reducing storage consumption

Explanation: Linux instant clones use the vSphere instant-clone architecture to create desktops rapidly from a golden image. The clones share underlying virtual-disk data instead of requiring a complete independent disk copy for each desktop. This significantly reduces storage consumption and contributes to fast provisioning. Horizon also uses internal objects such as templates, replicas, and parent VMs as part of the instant-clone architecture. Linux instant clones are automated rather than manual pools and require the appropriate vCenter and Horizon integration. Their efficiency is one of the major reasons instant-clone technology is commonly used for large nonpersistent Linux desktop environments.

Q245. Which Active Directory integration method does Omnissa currently recommend for offline domain join of Linux instant clones?

1. FTP authentication
   2. SSSD Authentication
   3. Local-only authentication
   4. SSH key authentication

Correct Answer: 2. SSSD Authentication

Explanation: Omnissa supports several Active Directory integration approaches for Horizon Linux desktops, including OpenLDAP pass-through, SSSD, PBISO in certain environments, and Samba. For offline domain join of instant-cloned Linux desktops, current documentation supports SSSD Authentication across supported Linux distributions and explicitly recommends it over Samba for this use case. SSSD provides integration with Active Directory while allowing instant-clone desktops to join the domain as part of the provisioning process. FTP, local-only accounts, and SSH key authentication do not provide the Active Directory offline-domain-join functionality required for centrally managed Horizon Linux clones.

Q246. Which Horizon Linux application-pool design allows multiple users to run sessions concurrently from the same host infrastructure?

1. Multi-session application pools based on a Linux farm
   2. Single-session desktop pools only
   3. Manual physical desktops only
   4. Dedicated Windows desktop pools

Correct Answer: 1. Multi-session application pools based on a Linux farm

Explanation: Horizon supports multi-session application pools using suitable Linux host machines organized into manual or automated instant-clone farms. Each published application can then support multiple user sessions across the farm infrastructure. This differs from a single-session application pool, where an application instance is associated with a single-session virtual desktop and supports one user session at a time. Omnissa also documents platform limitations for Linux application pools, so administrators must verify the selected Linux distribution. Multi-session Linux farms provide a scalable approach for delivering centrally hosted applications to many concurrent users.

Q247. Which statement is true about physical Linux machines and Horizon multi-session published application pools?

1. Physical Linux machines are required
   2. Physical machines provide better App Volumes integration
   3. Multi-session published application pools are not supported on physical Linux machines
   4. Physical machines must use PCoIP only

Correct Answer: 3. Multi-session published application pools are not supported on physical Linux machines

Explanation: Current Omnissa guidance states that Linux multi-session published desktop pools and single-session or multi-session application pools require supported virtual machines in a vSphere-based environment. Physical Linux machines do not support these published desktop and application configurations. The virtualized environment must also meet the required vSphere version and operating-system support criteria. Physical machines are therefore not a substitute for the supported Linux virtual host infrastructure. The limitation is unrelated to App Volumes or a requirement to use PCoIP. Administrators should verify platform support before designing multi-session Linux application services.

Q248. A user opens the same Linux published application from a second client device. What behavior should the administrator expect with the supported Linux application-session model?

1. Both client sessions always remain active independently
   2. A second Active Directory account is created
   3. The application is converted into a local application
   4. The first session is disconnected and reconnected on the second client

Correct Answer: 4. The first session is disconnected and reconnected on the second client

Explanation: Omnissa documents that Linux published applications do not support the configurable Multi-Session Mode behavior available in some other Horizon application scenarios. If a user opens a Linux published application on client A and then opens the same application, or another application from the same farm, on client B, the session on client A is disconnected and reconnected on client B. Horizon does not create two simultaneous independent sessions for that user through this Linux configuration. This behavior should be understood before deploying workflows that depend on concurrent application access from multiple endpoints.

Q249. Which limitation applies when a user already has a Linux published desktop session and then attempts to launch a published application from the same farm?

1. The desktop session is converted into an application pool
   2. Horizon Agent is automatically reinstalled
   3. Both sessions always run simultaneously
   4. Session stealing between the published desktop and application is not supported

Correct Answer: 2. Session stealing between the published desktop and application is not supported

Explanation: Horizon Agent for Linux does not support session stealing between published desktop and published application sessions from the same farm. If a user already has a published desktop session and then attempts to open a published application based on that farm, the desktop session remains active and the application session is not established. The reverse behavior also applies when an application session already exists. Horizon does not automatically convert one session type into another or reinstall the Agent. This limitation should be considered when designing Linux farms intended to deliver both published desktops and applications.

Q250. What display protocol is supported by Horizon Agent for macOS in the current limited-availability release?

1. Horizon Blast Extreme
   2. PCoIP only
   3. Microsoft RDP only
   4. ICA

Correct Answer: 4. Horizon Blast Extreme

Explanation: Horizon Agent for macOS currently uses Horizon Blast Extreme as its supported remote display protocol. Omnissa’s 2606 documentation explicitly states that PCoIP is not supported for macOS Agent desktops. Horizon Blast provides the display channel used by supported Horizon Clients connecting to eligible macOS machines. Microsoft RDP and ICA are not the documented Horizon Agent for macOS display protocols. Because the macOS Agent capability is in limited availability and has specific platform and feature restrictions, administrators should review the current support matrix before deploying it in production.

Q251. Which hardware platform is required for the current Horizon Agent for macOS limited-availability release?

1. Intel Mac Pro only
   2. Apple Silicon Mac using M4 or later
   3. Any Apple Silicon generation
   4. x86 Windows hardware running macOS virtualization

Correct Answer: 1. Apple Silicon Mac using M4 or later

Explanation: Current Omnissa Horizon 8 2606 documentation specifies Apple Silicon Mac hardware using M4 or later for Horizon Agent for macOS. Intel-based Mac hardware is not supported in this limited-availability release. Administrators must also satisfy the documented supported macOS versions and minimum Horizon Connection Server and Client versions. The requirement is therefore more specific than merely using any Apple Silicon Mac. Checking both hardware and software compatibility is essential because installing Horizon Agent on unsupported hardware can result in missing functionality or an unsupported deployment.

Q252. Which capability is currently supported by Horizon Agent for macOS?

1. Instant-clone desktop pools
   2. Published applications
   3. Real-Time Audio-Video
   4. Multi-session RDSH-style deployments

Correct Answer: 3. Real-Time Audio-Video

Explanation: The current Horizon Agent for macOS limited-availability feature set includes Horizon Blast Extreme, multiple monitors, audio input and output, Real-Time Audio-Video, and clipboard redirection. It does not currently support instant-clone desktop pools, published applications, USB redirection, smart-card redirection, or multi-session deployments. Real-Time Audio-Video allows supported audio and video devices to be used efficiently in remote conferencing scenarios. Because the macOS Horizon Agent feature set is more limited than that of mature Windows Horizon Agent deployments, administrators should confirm that required workflows are included before adopting it.

Q253. Which Horizon Agent for macOS feature is currently unsupported?

1. Clipboard redirection
   2. Multi-monitor display
   3. Audio output
   4. USB redirection

Correct Answer: 4. USB redirection

Explanation: USB redirection is currently listed as unsupported for Horizon Agent for macOS in the 2606 limited-availability release. Supported capabilities include clipboard redirection, multi-monitor operation, audio input and output, Real-Time Audio-Video, and Horizon Blast Extreme. This means organizations that depend on redirecting specialized USB devices into remote macOS desktops must evaluate alternative designs or wait for future support. The limitation illustrates why administrators should not assume feature parity across Windows, Linux, and macOS Horizon Agents. Platform-specific documentation should always be checked during solution design and compatibility planning.

Q254. What additional action is required to use Real-Time Audio-Video on a Linux Horizon Agent machine?

1. Perform the documented additional RTAV setup after installing Horizon Agent for Linux
   2. Convert the machine into a Windows RDSH server
   3. Install Horizon Connection Server on the Linux desktop
   4. Disable Horizon Blast

Correct Answer: 2. Perform the documented additional RTAV setup after installing Horizon Agent for Linux

Explanation: Real-Time Audio-Video is supported with Horizon Agent for Linux, but unlike the Windows Agent where RTAV is installed by default, Linux requires additional setup after Horizon Agent installation. Administrators must perform the documented RTAV configuration procedures so compatible webcam and audio devices can be redirected efficiently into the remote session. Horizon Connection Server should not be installed on the Linux desktop, and converting the machine into Windows would obviously defeat the Linux deployment. RTAV works with supported Horizon display protocols, including Horizon Blast, so Blast should not be disabled merely to enable the feature.

Q255. When Microsoft Teams is used with Horizon Real-Time Audio-Video, what minimum remote-desktop resources does Omnissa document?

1. 1 vCPU and 1 GB RAM
   2. 2 vCPUs and 2 GB RAM
   3. 4 vCPUs and 4 GB RAM
   4. 8 vCPUs and 32 GB RAM

Correct Answer: 3. 4 vCPUs and 4 GB RAM

Explanation: Current Omnissa Real-Time Audio-Video requirements specify that remote desktops using Microsoft Teams with RTAV should have at least 4 virtual CPUs and 4 GB of RAM. Video conferencing involves real-time media processing, application workload, and desktop-session overhead, so adequate resources are important for acceptable call quality and responsiveness. These figures represent the documented minimum for this specific scenario rather than a general sizing recommendation for every Horizon workload. Administrators should still perform capacity testing based on conferencing patterns, resolution, concurrent applications, and other workload characteristics before finalizing production desktop sizing.

Q256. Where must webcam and audio-device drivers normally be installed for Horizon Real-Time Audio-Video?

1. On the Horizon client device
   2. Only on Connection Server
   3. Only on Unified Access Gateway
   4. Only in the Horizon Events database server

Correct Answer: 1. On the Horizon client device

Explanation: Real-Time Audio-Video uses the webcam and audio devices attached to the endpoint. Omnissa states that the relevant webcam and audio-device drivers must be installed and operational on the Horizon client computer or access device. Administrators do not generally need to install those physical device drivers on the machine running Horizon Agent. This design helps avoid managing large numbers of endpoint-specific hardware drivers inside virtual desktop images. Connection Server and Unified Access Gateway broker or proxy access but do not host the endpoint device drivers. The Events database is entirely unrelated to peripheral functionality.

Q257. Which Horizon Web Client environment does not currently support Real-Time Audio-Video?

1. Horizon Web Client in a supported non-Safari browser
   2. Native Horizon Client for Windows
   3. Native Horizon Client for macOS
   4. Horizon Web Client running in Safari

Correct Answer: 2. Horizon Web Client running in Safari

Explanation: Real-Time Audio-Video is available with Horizon Web Client in supported browsers, but current Omnissa documentation specifically excludes Safari from RTAV support for Horizon Web Client. Native Horizon Client applications on supported Windows, Mac, Linux, mobile, and other documented platforms provide their own RTAV support according to the current compatibility matrix. Administrators planning browser-based conferencing should therefore validate the chosen browser rather than assuming all browsers offer identical multimedia capabilities. When RTAV is essential, selecting a supported browser or native Horizon Client provides the required optimized audio and video functionality.

Q258. What must an administrator verify about a virtual switch before provisioning a large Linux instant-clone pool?

1. That it has enough ports for the expected number of VM network adapters
   2. That it contains an Active Directory database
   3. That it runs Horizon Connection Server
   4. That it has an App Volumes package attached

Correct Answer: 4. That it has enough ports for the expected number of VM network adapters

Explanation: Each network adapter on a virtual machine requires a port on the virtual switch to which the instant-clone desktops connect. Before creating a large Linux instant-clone pool, Omnissa recommends verifying that the virtual switch has enough available ports for the expected number of machines and network interfaces. Insufficient virtual-switch capacity can cause provisioning or networking problems even when compute and storage resources are sufficient. Active Directory, Connection Server, and App Volumes packages are not stored or executed by the virtual switch. Network-capacity planning therefore includes both upstream bandwidth and sufficient virtual-switch port availability.

Q259. What should an administrator do after adding an existing Linux vSphere VM to a manual Horizon desktop pool if updated display settings need to take effect?

1. Reinstall vCenter Server
   2. Delete the machine from Active Directory
   3. Power off the virtual machine
   4. Convert the machine to an instant clone

Correct Answer: 3. Power off the virtual machine

Explanation: Omnissa documentation notes that after an existing vSphere virtual machine is added to a manual Linux desktop pool, the administrator should power off the machine so newly configured display settings can be applied. These settings can include monitor count, monitor resolution, and Screen DMA configuration. Because a manual pool does not use Horizon automated provisioning, Horizon does not recreate the desktop automatically merely to apply these settings. Deleting the computer account, reinstalling vCenter, or converting the machine into an instant clone is unnecessary and would not represent the documented procedure for applying the display configuration.

Q260. Which statement correctly compares automated and manual Linux desktop pools?

1. Automated pools can use Horizon-managed cloning, while manual pools use pre-existing machines managed outside Horizon’s lifecycle
   2. Manual pools always provide more lifecycle automation than automated pools
   3. Automated pools cannot use vCenter Server
   4. Manual pools require instant-clone parent VMs

Correct Answer: 1. Automated pools can use Horizon-managed cloning, while manual pools use pre-existing machines managed outside Horizon’s lifecycle

Explanation: Automated Linux desktop pools allow Horizon to create standardized machines from supported templates or snapshots using full-clone or instant-clone workflows. Horizon therefore participates directly in provisioning and lifecycle management. Manual pools are built from existing machines that administrators create and maintain outside Horizon’s automated lifecycle processes. Horizon can still broker access to those machines once Horizon Agent is installed and they are added to the pool. Manual pools do not require instant-clone parent VMs, and vCenter integration is central to many automated Linux provisioning workflows. Choosing between pool types depends on the level of automation and lifecycle control required.
