VMware Horizon 8.x Professional Free Sample Questions

The VMware Unified Access Gateway (UAG) is a hardened Linux appliance designed to be placed in a DMZ. It acts as a secure proxy for Horizon traffic and can be configured to delegate authentication to third-party identity providers using SAML, RADIUS, and other methods, thus preventing direct exposure of internal resources like Connection Servers and Active Directory.

Dynamic Environment Manager (DEM) is the ideal tool for this task. Using a 'Logon Task', an administrator can configure a script or command to run at user logon. This is processed by the DEM agent in the user's context and can be conditionally applied based on user, group, or other environmental factors, providing flexibility without altering the golden image.

A custom load balancing script can query performance counters like CPU usage and memory to generate a load index. This script provides the custom logic needed to balance sessions based on actual resource consumption rather than just session count.

The custom script must be stored in a location accessible by the Connection Server. The script path is then specified in the farm's load balancing settings in the Horizon Console.

This statement is true. App Volumes 4.x allows flexible assignment of packages. A package can be assigned to an Active Directory computer object, making the application available to any user who logs into that specific virtual machine. It can also be assigned to a user, following them across machines. If the same application is assigned to both, the computer-based assignment has priority.

The 'pending session expired' message typically indicates a communication breakdown between the Horizon Agent on the desktop VM and the Connection Server after the initial connection is brokered. The agent uses JMS over TCP port 4001 to send status updates. If a firewall blocks this port, the Connection Server never receives confirmation that the user has logged in, and the pending session reservation times out, causing the disconnect.

Instant Clones are the fastest provisioning technology in Horizon as they leverage VMware's vmFork technology to create running VMs from a parent template almost instantly. They also significantly reduce storage consumption by sharing the parent VM's disk. Combining Instant Clones with a vSAN datastore is a highly efficient and scalable solution for RDSH farms.

App Volumes Writable Volumes are designed for this exact use case. A Writable Volume is a user-specific VMDK that attaches at login and captures all file system and registry changes, such as user-installed applications. When used with a non-persistent desktop, the volume provides persistence for the user's changes during the session, but the underlying desktop is still destroyed or refreshed at logoff.

This condition allows the policy to trigger based on the source IP of the connecting client. The administrator would define the corporate IP ranges and create a rule that applies when the client's IP is NOT within those ranges.

When a user connects through a UAG, the UAG can pass specific tags to the Connection Server. A common practice is to configure external-facing UAGs with a tag like 'External'. The Smart Policy can then use this tag as a condition to identify external connections.

Session Roaming is the core Horizon feature that allows users to disconnect from a session on one client device and reconnect to the same session from a different device. This is fundamental for 'follow-me' desktop workflows common in healthcare and other industries where users are highly mobile within a facility.
