VMware 2V0-51.23 Practice Exam Questions & Answers

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.

To enable an instant-clone pool to use NVIDIA GRID vGPU, the administrator needs to do the following:

Install NVIDIA GRID vGPU in the physical ESXi hosts and select Shared Direct in the Host Graphics Settings12.

Prepare a golden image with NVIDIA GRID vGPU configured, including selecting the vGPU profile to use12.

Take a snapshot of the golden image12.

In Horizon Console, when creating an instant-clone pool, select Manage Using vSphere Client in the 3D Render field.Instant-clones inherit the settings configured in the vSphere Client for the golden image12.

Therefore, the possible reasons for the issue are:

The administrator has selected Shared instead of Shared Direct when editing the Host Graphics Settings for the ESXi host in the vCenter Server.This option is for vSGA, not vGPU3.

The golden image and snapshot that the administrator selected has not been configured for NVIDIA GRID vGPU.The administrator needs to verify that the correct vGPU profile is selected and that the NVIDIA drivers are installed in the golden image4.

The other options are not valid because:

Horizon 8 does have an explicit 3D renderer option for instant clone, but it is Manage Using vSphere Client, not NVIDIA GRID vGPU12.

Instant-clone pools do support NVIDIA GRID vGPU as long as the ESXi hosts and the golden image are properly configured12.

The default URL used to access the Horizon Console is https://<connection_server_FQDN>/admin, where <connection_server_FQDN> is the fully qualified domain name of the Connection Server instance. This URL allows you to log in to Horizon Console by using a secure (TLS) connection. You can also use the IP address of the Connection Server instance instead of the FQDN, but this might result in blocked access or reduced security due to certificate mismatch. You cannot use https://localhost to connect from the Connection Server host, but you can use https://127.0.0.1 instead. The other options are not valid URLs for Horizon Console.Reference:Log In to Horizon Console

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.

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.

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 the other 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.

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.Reference:
