2V0-51.23 Exam Questions & Answers

Correct Answer: D

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

The minimal level of Horizon Console access that the IT support center would need to help with Horizon desktop user issues is the Help Desk Administrators role. This role allows the IT support center to view and troubleshoot user sessions,

reset user passwords, send messages to users, and perform other help desk tasks. The Help Desk Administrators role can be assigned to users or groups on any access group that contains the desktop pools or farms that the IT support

center needs to support. The other options are not the minimal level of Horizon Console access for this scenario:

Local Administrators: This role allows full administration rights on a specific access group and its sub-access groups. This role can perform all the tasks of the Help Desk Administrators role, as well as create, edit, and delete desktop pools,

farms, applications, entitlements, and other objects. This role is more than what the IT support center needs to help with user issues.

Global Help Desk Administrators: This role allows full administration rights on all access groups in the Horizon environment. This role can perform all the tasks of the Local Administrators role, as well as create, edit, and delete access groups

and global entitlements. This role is more than what the IT support center needs to help with user issues.

Inventory Administrators: This role allows limited administration rights on a specific access group and its sub-access groups. This role can view and manage desktop pools, farms, applications, entitlements, and other objects, but cannot

create or delete them. This role can also perform some help desk tasks, such as viewing user sessions and sending messages to users, but cannot reset user passwords or troubleshoot sessions. This role is not sufficient for what the IT

support center needs to help with user issues.

Administrators: This role allows full administration rights on all access groups in the Horizon environment, as well as global settings, licensing, roles and permissions, events configuration, and other system-wide settings. This role can perform

all the tasks of theother roles, as well as configure and manage the Horizon infrastructure. This role is more than what the IT support center needs to help with user issues.

Correct Answer: B

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
