Before running the Horizon Connection Server installer, the user account performing the installation must be a domain user who is also a member of the local Administrators group on the target server. The installer needs these permissions to create the necessary services, modify the local system, and install the Active Directory Lightweight Directory Services (AD LDS) role, which is a core component of the Connection Server. Without these specific privileges, the installation will fail.

A. The host system must be a vSphere VM with a static IP address. While using a vSphere VM with a static IP is a critical best practice and a requirement for production, the installer does not technically prevent installation on a physical server.
C. An SSL server certificate must be installed on the Horizon Connection Server. The installer creates a default self-signed certificate. Installing a trusted SSL certificate is a crucial post-installation step, not a prerequisite for running the setup.
D. Install AD DS and AD LDS Tools on the Horizon Connection Server. The Connection Server installer automatically installs the required AD LDS role. Installing AD DS would make the server a domain controller, which is not a supported configuration.

The central location for managing desktop pools in the Horizon Console is under Inventory > Desktops.
1. Option B: By selecting a pool from this list, the administrator is taken to its details page. The Summary tab on this page contains a "Pool Settings" area that displays the pool's complete configuration.
2. Option C: Within that same Summary tab, the "vCenter Server" section provides real-time status information related to the pool's interaction with vCenter, such as the state of the parent VM, image publishing, and virtual machine provisioning, which is critical for monitoring its operational status.

A. Navigate to Inventory > Machines > click on a vCenter...: The vCenter object view in Horizon Console is for managing the vCenter connection itself, not for viewing individual pool settings.
D. Navigate to Inventory > Machines > click on a vCenter...: This navigation path is incorrect. Pool settings are managed under the Inventory > Desktops section, not from the vCenter object under Machines.

1. VMware Docs, Horizon 8 Administration, "Monitoring Desktop Pool Status". Describes navigating to Inventory > Desktops and selecting a pool to view its summary and status.

2. VMware Docs, Horizon 8 Administration, "Worksheet for Creating an Instant-Clone Desktop Pool". The settings listed in this worksheet correspond to the fields found in the "Pool Settings" section of the pool's summary tab in the Horizon Console (Inventory > Desktops > [Pool Name] > Summary).

The symptoms described point directly to an issue with the load balancer situated in front of the Unified Access Gateway (UAG) appliances. External sessions disconnecting randomly, while internal sessions are stable, isolates the problem to the external access path (Client -> LB -> UAG). Such disconnects are classic symptoms of misconfigured session persistence (affinity) or incorrect UDP timeouts on the load balancer. The Blast Extreme protocol, for instance, uses multiple connections that must be routed to the same UAG appliance for the duration of the session. If the load balancer fails to maintain this affinity or has an aggressive UDP timeout, the session will break.

B. A misconfigured load balancer for Connection Servers would impact internal users as well, but the scenario states internal sessions are not impacted.
C. Blocked firewall ports would typically prevent the session from establishing at all or cause specific features to fail, not cause random disconnects of an active session.
D. Blocked firewall ports between UAG and Connection Servers would likely prevent authentication or desktop enumeration, stopping the connection before it starts.

To configure a central Syslog server in VMware Horizon, an administrator must navigate to the "Event Configuration" menu located under the "Settings" drop-down in the left-hand navigation pane of the Horizon Console. This section is specifically designed for managing how and where the Horizon Connection Server records its operational events. Within this menu, administrators can input the Syslog server's fully qualified domain name (FQDN) or IP address and specify the designated UDP port. Once applied, the system will actively forward event log messages to the central Syslog aggregator for unified monitoring and auditing.

Before any parallel upgrade, you must prove that AD LDS (Horizon LDAP) replication is healthy. Running “repadmin /showrepl localhost:389” on each Connection Server enumerates inbound and outbound partners for that server’s AD LDS instance, confirming successful replication across the pod.

B: ViewDBChk scans machine entries; it does not test LDAP replication. C: vdmexport backs up LDAP data but provides no replication status. D: vdmadmin -S shows schema version information only.

A key benefit of Global Entitlements within a Horizon Cloud Pod Architecture is the abstraction of the underlying infrastructure from the end-user. When an application is published via a global entitlement, users are assigned to that entitlement rather than individual application pools on each pod. As a result, the user sees a single icon for the application in their client. When launched, the system automatically directs them to an available session on a suitable pod, providing a seamless experience across multiple sites.

B. This is the opposite of how Global Entitlements work. The goal is to entitle users once globally, not manage permissions on each pod individually.
C. The Cloud Pod Architecture, not the user, typically determines the optimal pod for application launch based on factors like user location and pod health.
D. The application must be created as a local application pool on each pod that will participate in the global entitlement before it can be included.

1. VMware Docs, Administering Cloud Pod Architecture in Horizon 8, Version 2203, "Global Entitlements". The documentation states, "A global entitlement provides the link between users and their desktops and applications, regardless of where those resources are located."

2. VMware Docs, Administering Cloud Pod Architecture in Horizon 8, Version 2203, "Creating Global Application Entitlements". This section details that a global application entitlement "can contain application pools from any of the pods in the pod federation." It further explains that users see one icon for the application.

To assign a home site to a user in a VMware Horizon Cloud Pod Architecture (CPA) environment, administrators must select the "Users and Groups" menu option from the left navigation pane. While the currently selected "Sites" node under "Settings" is used to define and manage the sites themselves, the actual entitlement and mapping of a specific user or group to a home site is handled within the user management interface. By navigating to "Users and Groups," administrators can search for the target user, select their profile, and assign the designated Home Site.

The described behavior—a black screen followed by a disconnect for external UAG users while internal connections work—is a classic symptom of a role conflict between the Unified Access Gateway (UAG) and the Horizon Connection Server. When a UAG is deployed to handle external access, it must be the sole gateway for secure remote connections. If the Connection Server's own gateway services (Blast Secure Gateway and PCoIP Secure Gateway) are also enabled, the Connection Server incorrectly instructs the client to establish the protocol session with itself instead of through the UAG, causing the connection to fail. Disabling these gateway roles on the Connection Server resolves this conflict.

A. Update the Blast External URL in UAG with port number: The Blast External URL must be correct, but the root cause is the Connection Server's conflicting gateway role, not the URL itself.
B. Upload the Blast Proxy Certificate in Horizon Edge Settings: Certificate issues would typically cause trust errors or prevent the initial connection, not a black screen after authentication.
C. Enable Tunnel in UAG: The UAG tunnel is for the primary authentication traffic. The issue is with the secondary protocol (Blast) connection being misdirected by the Connection Server.

Section: "Configure Horizon Settings". This guide explicitly states: "When Unified Access Gateway is used

the secure gateways (Blast Secure Gateway and PCoIP Secure Gateway) on the Horizon Connection Server must be disabled."

Document ID: 20005308-GD. The diagrams illustrate that for UAG deployments

protocol traffic from external clients terminates at the UAG

not the Connection Server

reinforcing that the Connection Server should not act as a gateway.

VMware Horizon has specific requirements for VMs to be selectable as golden images: (1) The VM must have exactly one snapshot - no more, no less; (2) If using Windows Server OS, the pool/farm must have Windows Server desktops enabled; (3) The VM must have a snapshot present. These three conditions directly control visibility in the golden image selection list.

A. Optimization doesn't affect golden image list visibility.
E. CD-ROM configuration is not a selection requirement.
F. Guest OS version mismatch doesn't prevent list appearance.

Virtual Shared Graphics Acceleration (vSGA), also known as Virtual Shared 3D rendering, is the only hardware-accelerated graphics option that supports vMotion. vSGA allows multiple VMs to share a single physical GPU while maintaining the ability to migrate VMs between hosts. This is achieved through the VMware SVGA 3D driver, which provides hardware acceleration while abstracting the physical GPU, enabling vMotion compatibility.

B. Virtual Shared Pass-through Graphics Acceleration - This is not a valid VMware graphics acceleration type; it conflates incompatible concepts.
C. Virtual Shared Direct access 3D - This is not a recognized VMware graphics acceleration technology name.
D. Virtual Dedicated Graphics Acceleration (vDGA) - Uses GPU pass-through which binds VMs to specific hardware, preventing vMotion.
