Correct Answer: C

The VMware Horizon component that needs to be deployed to allow users to log into VMware Workspace ONE Access and connect to remote desktops and applicationswithout having to provide Active Directory credentials is the Enrollment Server. The Enrollment Server is a standalone service that integrates with VMware Workspace ONE Access and enables True Single Sign-On (SSO) for Horizon clients that are using non-AD-based authentication methods such as RSA SecureID, RADIUS, or SAML1. The Enrollment Server requests short-lived certificates on behalf of the users from a certificate authority (CA), and these certificates are used for authentication to the Horizon environment2. The Enrollment Server must be installed and configured in the same domain or forest as the Connection Server, and it must have an enrollment agent certificate that authorizes it to act as an enrollment agent2. The other options are not valid or feasible because: A Replica Server is a Connection Server instance that replicates the Horizon LDAP configuration data from another Connection Server instance, and provides high availability and load balancing for user connections3. A Replica Server does not request or issue certificates for users, and it does not integrate with VMware Workspace ONE Access. A Security Server is a Connection Server instance that resides within a DMZ and acts as a proxy for external user connections to the Horizon environment4. A Security Server does not request or issue certificates for users, and it does not integrate with VMware Workspace ONE Access. Security Servers are deprecated in Horizon 8 and replaced by Unified Access Gateways (UAGs)4. A vCenter Server is a management platform that provides centralized control and visibility of vSphere hosts and virtual machines in the Horizon environment5. A vCenter Server does not request or issue certificates for users, and it does not integrate with VMware Workspace ONE Access.

Correct Answer: D

In a load balanced Horizon POD with three Connection Servers, there are 450 active Blast sessions connected. If one of these Connection Servers runs into an unplanned outage, only the active sessions from the failed Connection Server are disconnected, because HTTPS Secure Tunnel is disabled. This means that the other two Connection Servers can still handle the remaining sessions without interruption. The HTTPS Secure Tunnel is a feature that allows Horizon Client devices to establish secure connections to virtual desktops and applications through the Connection Server. When this feature is enabled, all the display protocol traffic is tunneled through the Connection Server, which acts as a proxy between the client and the desktop. This increases the security and simplifies the network configuration, but also adds some overhead and dependency on the Connection Server availability1. When this feature is disabled, the Horizon Client devices connect directly to the desktops using their IP addresses or hostnames, bypassing the Connection Server. This reduces the load and dependency on the Connection Server, but also requires more network configuration and firewall rules to allow direct access to the desktops2. The Blast Secure Gateway is a similar feature that allows Horizon Client devices to establish secure connections to virtual desktops and applications using the Blast Extreme protocol through the Connection Server. When this feature is enabled, the Blast Extreme traffic is tunneled through the Connection Server, which acts as a gateway between the client and the desktop. When this feature is disabled, the Horizon Client devices connect directly to the desktops using Blast Extreme3. In this scenario, both HTTPS Secure Tunnel and Blast Secure Gateway are disabled, which means that the Horizon Client devices connect directly to the desktops using Blast Extreme. Therefore, if one of the Connection Servers fails, only the sessions that were authenticated by that Connection Server are affected. The other sessions can continue without interruption, as long as they can reach their desktops directly4. The other options are not correct for this scenario: All 450 active sessions are disconnected, and have to re-connect again by the end-user. This would be true if HTTPS Secure Tunnel or Blast Secure Gateway were enabled, and all the display protocol traffic was tunneled through the Connection Server. In that case, any failure of a Connection Server would disconnect all the sessions that were using it as a proxy5. All active sessions will stay connected, because HTTPS Secure Tunnel and Blast Secure Gateway are disabled. This would be true if there was no dependency on the Connection Server after authentication. However, even with HTTPS Secure Tunnel and Blast Secure Gateway disabled, there is still some communication between the Horizon Client and the Connection Server for session management and heartbeat monitoring. If a Connection Server fails, these communications are lost and the sessions are terminated. All 450 active session are logged off immediately. This would be true if there was a global setting in Horizon Console to log off users when a Connection Server fails. However, there is no such setting in Horizon Console. The default behavior is to disconnect users when a Connection Server fails, not log them off.

Correct 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 volumesare 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.

Correct Answer: D

VMware Blast policy settings are stored in the registry key HKLM\Software\Policies\VMware, Inc.\VMware Blast\Config on the remote desktops or RDS hosts that use the VMware Blast display protocol. These settings can be configured by using the VMware Blast ADMX template file (vdm_blast.admx) and applying it through Microsoft Group Policy Object (GPO). Some of these settings can be changed in real time, which means that they take effect immediately after the policy is applied, without requiring a reboot or a reconnection of the Horizon Client. However, some of these settings cannot be changed in real time, which means that they require a reboot or a reconnection of the Horizon Client to take effect. The effect of changing any VMware Blast policy that cannot be changed in real time is that the Microsoft GPO update rules apply and GPOs are updated manually or by restarting the Horizon Agent. This means that the new policy settings will not be applied until one of the following events occurs: The Horizon Agent service is restarted on the remote desktop or RDS host. This can be done manually by using the Services console or the command-line tool sc.exe, or automatically by using a scheduled task or a script. The remote desktop or RDS host is rebooted. This can be done manually by using the Restart option in Windows, or automatically by using a scheduled task or a script. The Group Policy refresh interval is reached. This is a configurable time interval that determines how often the system checks for and applies new or changed GPOs. By default, this interval is 90 minutes for domain members and 5 minutes for domain controllers, with a random offset of 0 to 30 minutes. This interval can be modified by using the Group Policy refresh interval for computers setting in the ComputerConfiguration\Administrative Templates\System\Group Policy folder of the Group Policy Management Console. Therefore, to ensure that the VMware Blast policy settings that cannot be changed in real time are applied as soon as possible, it is recommended to restart the Horizon Agent service or reboot the remote desktop or RDS host after applying the policy.

Correct Answer: AD

Thin Clients and Zero Clients have the lowest cost of ownership and are easier to manage due to their minimalistic design, which lacks a full operating system, resulting in fewer components that require updates. These clients are designed for remote desktop services like VMware Horizon, where the computing work is done on the server side, making firmware updates and monitoring simpler and more centralized.

Correct Answer: BDF

A golden image must have a current snapshot to be used for cloning, and having multiple active snapshots can cause confusion and issues in the provisioning process. Additionally, selecting the correct Guest OS version is crucial for compatibility and optimal performance. These factors must be correctly configured for a VM to appear in the list of available golden images for provisioning.

Correct Answer: C

For a global entitlement to include local desktop pools, the settings and configurations of the global entitlement must be compatible with those of the local pools. If there is a mismatch in settings, such as display protocol, user assignment type (dedicated or floating), or other critical configurations, the local pools will not appear as selectable options when adding them to a global entitlement.
