Question 1

An administrator configured a virtual machine to use an NVIDIA card but the virtual machine is not starting up.

What could be the cause of the issue? (Choose two.)

A3D graphics cannot be used with local storage.

BThe Desktop Pool doesn't support 3D cards.

CNo suitable host could be found.

DNot all memory has been reserved on the VM.

ENot all CPU has been reserved on the VM.

Answer : C, D

When configuring a virtual machine to use an NVIDIA graphics card, issues such as the VM not starting can occur if there is no suitable host available that meets the requirements for 3D graphics, or if not all memory required by the 3D graphics card has been reserved for the VM. Ensuring that the host has the necessary 3D graphics capabilities and that the VM is configured with reserved memory can resolve these issues.

Question 2

A new Horizon environment has gone into production. External sessions are being disconnected after a random period of time.

The following information has been documented by the administrator:

. Internal and external users are able to connect to their desktops.

. External sessions connect via Unified Access Gateway.

. Users are immediately able to reconnect but are disconnected again in a few minutes.

. Due to limited amount of public IP addresses, all traffic flows through a load balancer.

. Internal sessions, connected directly to the desktops, are not impacted.

. While the session remains connected, all expected functionality works properly.

What could be a cause of this issue?

AA misconfigured network load balancer is in front of the Unified Access Gateway appliances.

BA misconfigured network load balancer is in front of the Connection Servers.

CRequired firewall ports are not open in front of the Unified Access Gateway appliances.

DRequired firewall ports are not open in front of the Connection Servers.

Answer : A

The disconnections of external sessions while internal sessions remain stable suggest an issue with the network infrastructure external to the Horizon environment, specifically with the load balancer placed in front of the Unified Access Gateway (UAG) appliances. Misconfigurations such as improper session persistence settings can lead to sessions being disconnected or improperly routed, causing the observed random disconnections.

Question 3

An administrator needs to configure BLAST Bandwidth Profiles to define the quality, maximum session bandwidth, and frame rate.

Which are the two possible ways an administrator can accomplish this goal? (Choose two.)

ACreate a login script which will set all required settings in the desktop.

BUse post-synchronization scripts during pool creation to define these settings.

CConfigure these BLAST settings in the desktop pool configuration.

DUse Horizon Smart Policies of Dynamic Environment Manager.

ESet all required settings from a profile manually through GPO policies.

Answer : D, E

Configuring BLAST Bandwidth Profiles involves setting quality, maximum session bandwidth, and frame rate controls. This can be effectively managed using Horizon Smart Policies within VMware's Dynamic Environment Manager (DEM), which allows administrators to create contextual policies that dynamically adapt to the end-user's environment. Alternatively, Group Policy Objects (GPOs) can be used to manually set these configurations across the desktop environment, providing a more static approach to enforcing these settings.

Question 4

An administrator needs to upgrade a Unified Access Gateway (UAG) appliance. The UAG is connected to a load balancer with other UAGs and has existing sessions.

Which option provided allows minimal downtime for maintenance?

AEnable Quiesce Mode in the UAG Admin UI.

BRemove the Horizon Connection Server thumbprint in the UAG Admin UI.

CSuspend the UAG appliance.

DPower off the UAG appliance.

Answer : A

Enabling Quiesce Mode in the Unified Access Gateway (UAG) Admin UI is the recommended approach for minimizing downtime during maintenance or upgrades when the UAG is part of a load-balanced cluster. Quiesce Mode allows the UAG to stop accepting new connections while allowing existing sessions to continue until they naturally end. This ensures minimal disruption to users and allows for a controlled upgrade process.

Question 5

How does an administrator enable debug logging for a single user in VMware Dynamic Environment Manager?

AUpdate the FlexEngine registry to DEBUG.

BCreate an empty FlexDebug.log file in the log folder.

CCreate an empty FlexDebug.txt file in the log folder.

DConfigure the FlexEngine GPO to DEBUG.

Answer : C

To enable debug logging for a single user in VMware Dynamic Environment Manager, the administrator needs to create an empty FlexDebug.txt file in the same folder as the standard log file for this user.This will trigger FlexEngine to switch to debug logging for this particular user1.Debug logging is useful for troubleshooting purposes, as it provides more detailed information about the FlexEngine operations and actions1.

The other options are not correct because:

Updating the FlexEngine registry to DEBUG will not enable debug logging for a single user, but for all users who log on to the same computer.This option can only be set through Group Policy settings and applies to all users1.Moreover, this option is not recommended, as it can cause performance issues and disk space consumption due to the large size of the log files1.

Creating an empty FlexDebug.log file in the log folder will not enable debug logging for a single user, as the file name must be exactly FlexDebug.txt.The file extension must be .txt, not .log1.

Configuring the FlexEngine GPO to DEBUG will not enable debug logging for a single user, but for all users who are affected by the GPO.This option can only be set through Group Policy settings and applies to all users1.Moreover, this option is not recommended, as it can cause performance issues and disk space consumption due to the large size of the log files1.

Question 6

An administrator is configuring load-balancing settings in Horizon Console for a RDSH Farm. Which two check boxes can be selected to influence the load balancing behavior? (Choose two.)

AThe floating dynamic host profile setting, created in the vSphere profile section.

BThe use custom script setting for customized RDSH load balancing.

CThe Include Session Count setting to include the session count on the RDSH for load balancing.

DThe Horizon DRS setting for fully automated vSphere load balancing.

Answer : B, C

Load balancing is a feature that allows administrators to distribute the load of published desktop and application sessions across multiple RDS hosts in a farm. Load balancing can improve the performance and availability of the sessions and the hosts. Horizon offers two ways of configuring load balancing for RDS hosts: using load balancing settings in Horizon Console or using custom load balancing scripts.

The load balancing settings in Horizon Console allow administrators to define how Horizon calculates the server load index, which indicates the load on each RDS host. The server load index can range from 0 to 100, where 0 represents no load and 100 represents full load. A server load index of -1 indicates that load balancing is disabled. Horizon uses the server load index to determine which RDS host is the best candidate for placing a new session request.

The load balancing settings in Horizon Console include the following check boxes that can be selected to influence the load balancing behavior:

The use custom script setting for customized RDSH load balancing: This setting allows administrators to override the default behavior of the load balancing settings and control the placement of new sessions by writing and configuring custom load balancing scripts. The custom scripts must write the server load index to a specific registry key on each RDS host. Horizon will use the value from the registry key instead of calculating it from the other settings.

The Include Session Count setting to include the session count on the RDSH for load balancing: This setting allows administrators to include the number of sessions (connected, pending, and disconnected) on each RDS host as a factor in calculating the server load index. By default, Horizon uses the following formula to calculate the server load index based on the session count: (connected sessions + pending sessions + disconnected sessions)/ (maximum session count). If the maximum session count is configured as unlimited, Horizon falls back to using the absolute number of total sessions.

The other options are not check boxes that can be selected in the load balancing settings in Horizon Console:

The floating dynamic host profile setting, created in the vSphere profile section: This option is not related to load balancing for RDS hosts, but rather to dynamic environment manager for instant-clone desktops. A dynamic host profile is a vSphere profile that contains configuration settings for instant-clone desktops, such as network settings, domain join settings, and customization scripts. A floating dynamic host profile is a type of dynamic host profile that applies to floating desktop pools, where users are assigned a random desktop from a pool at each login.

The Horizon DRS setting for fully automated vSphere load balancing: This option is not related to load balancing for RDS hosts, but rather to distributed resource scheduler (DRS) for vSphere clusters. DRS is a feature that monitors and balances the CPU and memory resources across multiple ESXi hosts in a cluster. DRS can also migrate virtual machines between hosts using vMotion to optimize resource utilization and performance. Horizon DRS is an extension of DRS that integrates with Horizon and provides additional capabilities, such as affinity rules, maintenance mode, and power management. Horizon DRS can be configured with different automation levels, such as fully automated, partially automated, or manual.

Question 7

An administrator needs to deploy an application to specific users in their instant-clone desktop environment with the following characteristics:

* The application needs to be updated very frequently.

* The application needs to be installed as soon as possible.

* The application is not multi-user aware.

Which solution would meet the requirements?

AVMware Horizon Published Application

BVMware Dynamic Environment Manager

CVMware ThinApp

DVMware App Volumes

Answer : D

VMware App Volumes is a real-time application delivery system that allows administrators to assign applications to users and groups in Horizon. App Volumes uses virtual disks called packages to store and deliver applications. When a user logs on to a desktop, the App Volumes agent attaches the assigned packages to the desktop and merges them with the OS disk. The user can then access the applications as if they were natively installed.

App Volumes is a suitable solution for deploying an application to specific users in an instant-clone desktop environment with the following characteristics:

The application needs to be updated very frequently: App Volumes allows administrators to update applications in real time by using the update or push-image operations. These operations replace the existing packages with new ones that have the latest updates applied, without affecting the user data or settings. The updated packages are delivered to the users at the next login or refresh.

The application needs to be installed as soon as possible: App Volumes allows administrators to install applications quickly and easily by using a clean packaging system and capturing the application installation process. The resulting package can be assigned to users or groups immediately, without requiring any recomposing or rebooting of the desktops.

The application is not multi-user aware: App Volumes allows administrators to deliver applications that are not multi-user aware by using writable volumes. Writable volumes are user-specific virtual disks that store user-installed applications, data, and settings. Writable volumes can be attached to desktops along with application packages, and they can isolate the user-installed applications from the system-installed applications.

The other options are not suitable for meeting the requirements:

VMware Horizon Published Application: This option allows administrators to publish applications from RDS hosts to users in Horizon. However, this option requires a separate RDS infrastructure and licensing, and it does not support instant updates or writable volumes for user-installed applications.

VMware Dynamic Environment Manager: This option allows administrators to manage user profiles and policies in Horizon. However, this option does not deliver or update applications, and it does not support writable volumes for user-installed applications.

VMware ThinApp: This option allows administrators to package applications into portable executables that can run on any Windows system without installation. However, this option requires a separate packaging process and licensing, and it does not support instant updates or writable volumes for user-installed applications.
