Troubleshoot and Optimize the VMware Solution · Network Troubleshooting
A user is reporting intermittent connection failures to their Horizon desktop. The Horizon administrator checks the Horizon Events database and finds repeated entries stating 'The pending session for user on machine has expired'. The user confirms they are being disconnected before the session is fully established. What is the most likely cause of this issue?
Show answer & explanation
Correct answer: D
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.

VMware Solution · Instant Clones
An administrator needs to deploy a new set of RDSH servers for a published application pool. The requirements are to provision the servers as quickly as possible and to minimize storage consumption. The underlying vSphere cluster is enabled for vSAN. Which combination of technologies should be used?

Correct answer: C
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.

Install, Configure, Administrate the VMware Solution · App Volumes Writable Volumes
A Horizon architect is designing a solution for a university computer lab. The primary requirement is that each student receives a non-persistent desktop that is refreshed to a pristine state upon logoff. However, students must be able to install specific educational software during their session and have it persist until they log off. Which technology should be used to provide this temporary, session-based application persistence?
Show answer & explanation
Correct answer: C
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.

Install, Configure, Administrate the VMware Solution · Dynamic Environment Manager (DEM) Smart Policies
An administrator is configuring Horizon Smart Policies through Dynamic Environment Manager (DEM) to enhance security. The goal is to disable clipboard redirection for any user connecting from a non-corporate, external network. Which two conditions must be configured in the Smart Policy definition to achieve this? (Select TWO)
Show answer & explanation
Correct answers: B, D
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.

VMware Solution · Session Management
A hospital is using Horizon 8 with non-persistent desktops and Imprivata OneSign for tap-and-go authentication. Clinicians move between patient rooms and tap their badge to quickly disconnect their session from one endpoint and resume it on another. Which Horizon feature is essential for this workflow to function seamlessly?
Show answer & explanation
Correct answer: D
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.

Troubleshoot and Optimize the VMware Solution · Instant Clone Troubleshooting
During the creation of an Instant Clone pool, the process fails at the 'Publishing Image' stage. The error in the Horizon Console indicates that the internal template creation failed. The administrator verifies that the parent VM, snapshot, and AD configuration are correct. What is a common cause for this specific failure?
Show answer & explanation
Correct answer: C
During the image publishing process, Horizon creates several internal VMs (template, replica, parent). These VMs are powered on briefly to perform customization tasks. They require an IP address from a DHCP server to communicate with the Connection Server. If a DHCP lease cannot be obtained on the designated vSphere port group, the process will fail.

Install, Configure, Administrate the VMware Solution · Cloud Pod Architecture (CPA)
The PowerShell command to configure a Global Entitlement with the 'Home Site' policy enabled is
Update-GlobalEntitlement -EntitlementName 'Win10-Dev' -_____'.Show answer & explanation
Correct answer: B
The correct parameter for the
Update-GlobalEntitlementcmdlet to enable the Home Site policy is-UseHomeSite $true. This configures the entitlement to always direct users to their assigned home site, if one is set. - Question 8Intermediate
Install, Configure, Administrate the VMware Solution · Desktop Pools
An organization wants to provide its developers with persistent desktops where they have administrative rights. Due to the high cost of storage, the infrastructure team wants to use a storage-efficient provisioning method and also ensure that OS patches can be applied without affecting the developers' installed applications and data. Which type of desktop pool best fits these requirements?
Show answer & explanation
Correct answer: C
This combination provides the best of both worlds. Instant Clones offer fast, storage-efficient provisioning. App Volumes Writable Volumes capture all user-installed applications and data on a separate, persistent disk. This allows administrators to patch or update the base golden image and refresh the desktops without affecting the user's personalized environment, which is reattached at login.
- Question 9Beginner
VMware Solution · Remote Display Protocols
When configuring the VMware Blast Extreme protocol via GPO, an administrator wants to prioritize image quality for a group of graphic designers, even if it means consuming more bandwidth. Which H.264 Quality Level setting should be configured?
Show answer & explanation
Correct answer: B
The 'Lossless' setting for the H.264 Quality Level ensures the highest possible image fidelity, as no compression artifacts are introduced. This is ideal for use cases like graphic design or medical imaging where pixel-perfect representation is critical, but it comes at the cost of significantly higher bandwidth consumption.
