Correct Answer: C

Explanation: 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: CE

Explanation: The two options that are available for the administrator to make the shortcut available to all desktop pool users, while minimizing ongoing administrative effort, before updating the desktop pool golden image are: Copy the shortcut to c:\users\Public\Desktop. This option will place the shortcut in the public desktop folder, which is shared by all users who log on to the same computer. The public desktop folder is normally a hidden folder, so the administrator needs to enable the option to show hidden files and folders in File Explorer1. This option does not require any additional software or configuration, but it will only work for the existing desktops in the pool. If new desktops are added or refreshed, the shortcut will not be copied automatically. Configure a Shortcut with DEM (Dynamic Environment Manager). This option will use the DEM console to create a shortcut configuration that will apply the shortcut to the user's desktop during logon2. The administrator needs to install and configure DEM on the Horizon environment, and create a configuration share and a profile archive share for storing the DEM settings3. This option requires more initial setup, but it will work for any desktop in the pool, regardless of whether it is new or refreshed. It also allows more flexibility and control over the shortcut properties and conditions. The other options are not valid or feasible because: Copying the shortcut during user provisioning to a non-writeable App Volume will not work because App Volumes are used to deliver applications, not shortcuts. App Volumes are virtual disks that are attached to the virtual machines at runtime, and they contain application files, registry entries, and settings4. Copying a shortcut to an App Volume will not make it appear on the user's desktop. Copying the shortcut to the Windows Default Domain Controller Policy will not work because this policy is used to configure settings for domain controllers, not desktops. The Default Domain Controller Policy is a Group Policy Object (GPO) that is linked to the Domain Controllers organizational unit (OU) in Active Directory, and it contains security settings that are applied to all domain controllers in the domain5. Copying a shortcut to this policy will not affect any desktops in the Horizon environment. Configuring a Shortcut with Horizon View Client will not work because Horizon View Client is used to connect to remote desktops and applications, not to create shortcuts. Horizon View Client is a software application that runs on various devices and platforms, and it allows users to access their virtual desktops and applications through a secure connection6. Configuring a shortcut with Horizon View Client will not make it appear on the user's desktop.

Correct Answer: D

Explanation: On a VMware vCenter managed virtual machine, the VMware Horizon Agent knows which Connection Server it should register with during the Instant Clone pool creation process by querying VMware Tools for a Guestlnfo Variable during the cloning process. The Guestlnfo Variable is a custom property that is set on the parent virtual machine and contains the FQDN of the Connection Server. When the parent virtual machine is cloned, the Guestlnfo Variable is copied to the clone and read by the Horizon Agent. The Horizon Agent then registers with the Connection Server specified in the Guestlnfo Variable12. The other options are not correct for this scenario: Administrator provides this information in the "Add Pool" creation wizard. This option is not correct because the administrator does not need to provide the Connection Server information in the "Add Pool" creation wizard. The administrator only needs to select the vCenter Server, data center, cluster, resource pool, datastore, network, and snapshot of the parent virtual machine. The Connection Server information is already embedded in the parent virtual machine as a Guestlnfo Variable3. Horizon Agent retrieves this information from an DNS SRV record. This option is not correct because the Horizon Agent does not use DNS SRV records to find the Connection Server during the Instant Clone pool creation process. DNS SRV records are used by Horizon Client devices to discover Connection Servers when they connect to a Horizon environment. DNS SRV records are optional and can be configured by the administrator to simplify client connections4. Administrator provides this information in the Horizon Agent Installation Wizard on the master image. This option is not correct because the administrator does not need to provide the Connection Server information in the Horizon Agent Installation Wizard on the master image. The administrator only needs to select the features and options that are required for the desktop pool, such as VMware Horizon Instant Clone Agent, VMware Dynamic Environment Manager, VMware App Volumes, and so on. The Connection Server information is set on the master image after it is converted to a parent virtual machine by using a PowerShell script5. References: Instant Clones: How Does It Work?

Correct Answer: A

Explanation: Application Profiler is a tool that analyzes the registry and file system locations where the settings for a particular application are stored, and creates a Flex configuration file for use with Dynamic Environment Manager. Application Profiler is installed using VMware Dynamic Environment Manager Enterprise Setup Wizard and explicitly selecting local drive installation1. This option allows you to install Application Profiler on a separate machine from the Dynamic Environment Manager Agent or Management Console. Alternatively, you can install Application Profiler on the same machine as the Dynamic Environment Manager Agent or Management Console, by selecting network share installation1. VMware Dynamic Environment Manager Agent and the Application Profiler can be installed on the same machine, but it is not recommended. This is because the Dynamic Environment Manager Agent might interfere with the profiling process by applying settings to the application being profiled1. Therefore, it is best to use a clean system for profiling applications. Application Profiler is not installed automatically when installing VMware Dynamic Environment Manager FlexEngine or Management Console. FlexEngine is the component that applies the user environment settings during logon, logoff, and session reconnect or disconnect events2. Management Console is the component that allows you to configure and manage the user environment settings2. Neither of these components requires Application Profiler to function. Application Profiler is an optional tool that helps you create Flex configuration files for applications that are not included in the predefined settings library1.

Correct Answer: B

Explanation: The reason for the issue is that the administrator may not have added an instant clone domain administrator to VMware Horizon. This is a requirement for creating an automated farm of instant-clone virtual machines using the

Add Farm wizard. An instant clone domain administrator is a user account in Microsoft Active Directory that allows Connection Server to perform certain operations related to instant clones in Active Directory, such as joining instant-clone

virtual machines to the domain, creating computer accounts, and deleting computer accounts. The administrator must create and configure this account in Active Directory and then specify the user name and password in VMware Horizon.

To add an instant clone domain administrator to VMware Horizon, the administrator needs to follow these steps:

In the Horizon Console, select Settings > Domains > Domain Accounts.

Click Add.

Enter the domain, user name, and password for the instant clone domain administrator.

After adding the instant clone domain administrator to VMware Horizon, the administrator can proceed with creating an automated farm of instant-clone virtual machines using the Add Farm wizard.

The other options are not the reason for the issue:

In the Add Farm wizard, the administrator may not have selected Automated Farm as farm type: This option is not relevant to the issue, as the farm type selection is done in a later page of the Add Farm wizard, after selecting the domain and

the AD container. The page displayed in the exhibit is the Identification and Settings page, which is the first page of the Add Farm wizard. The administrator did not prepare a RDSH golden image snapshot: This option is not relevant to the

issue, as the RDSH golden image snapshot selection is done in a later page of the Add Farm wizard, after selecting the domain and the AD container. The page displayed in the exhibit is the Identification and Settings page, which does not

require a RDSH golden image snapshot. The administrator did not add the RDSH golden image to the correct domain: This option is not relevant to the issue, as the RDSH golden image domain selection is done in a later page of the Add

Farm wizard, after selecting the domain and the AD container. The page displayed in the exhibit is the Identification and Settings page, which does not require a RDSH golden image domain. References: Configuring an Instant Clone Domain

Correct Answer: A

Explanation: The action that must first be performed to ensure that there are no issues with Horizon LDAP replication within the Pod is to execute repadmin.exe/showrepl localhost:389. This command will display the replication status of the local Connection Server instance and show any errors or warnings that might affect the replication process1. The administrator should run this command on each Connection Server instance in the Pod before upgrading them in parallel, and resolve any issues that are reported. The other options are not valid or feasible because: Executing ViewDBChk.cmd --scanMachines will not check the Horizon LDAP replication status, but rather scan the vCenter Server inventory for virtual machines that are managed by Horizon and report any inconsistencies or errors2. This command is useful for troubleshooting virtual machine issues, but not for verifying LDAP replication. Executing vdmexport.exe -f Myexport.lDF will not check the Horizon LDAP replication status, but rather export the Horizon LDAP configuration data to a file named Myexport.lDF3. This command is useful for backing up or restoring the Horizon LDAP data, but not for verifying LDAP replication. Executing vdmadmin.exe -S will not check the Horizon LDAP replication status, but rather display the health status of the Connection Server instances in the Pod4. This command is useful for monitoring the Connection Server performance and availability, but not for verifying LDAP replication.

Correct Answer: A

Explanation: To improve the user experience when using Application Profiler from Dynamic Environment Manager to create application-specific user defined settings, the administrator can configure exclusions to filter out unnecessary folders and registry entries. Exclusions are rules that specify which file system or registry locations are not included in the Flex configuration file. Exclusions can reduce the size of the Flex configuration file and the profile archive, and improve the performance of the application profiling and synchronization processes12. The other options are not valid or effective because: Changing the default save path does not affect the size or content of the Flex configuration file or the profile archive. It only changes where the files are stored on the local machine3. Using Deepest Registry Path does not reduce the size of the Flex configuration file or the profile archive. It only changes how the registry locations are displayed in the Application Profiler interface4. There is no such thing as Cloud Entitlements in Dynamic Environment Manager. The correct term is Global Entitlements, which are used in Cloud Pod Architecture to entitle users to desktops or applications across multiple pods5.

Correct Answer: C

Explanation: 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.
