A screenshot of a computer program Description automatically generated VMware Horizon is designed to deliver a virtual desktop and application infrastructure, providing IT with a modern, streamlined approach to deliver, protect, and manage Windows and Linux virtual desktops and applications while containing costs and ensuring that end users can work anytime, anywhere, on any device. Horizon 8 supports flexible hybrid and multi-cloud deployment options and offers an optimized experience with unified communication and collaboration tools. The VMware Blast Extreme Protocol, included with Horizon 8, is a dynamic display protocol that delivers an immersive, feature-rich user experience across devices, locations, media, and network connections.

VMware Workspace ONE UEM (Unified Endpoint Management) is crucial for ensuring that end-user devices comply with an organization's IT policies. It manages and secures endpoints like smartphones, tablets, laptops, and desktops, streamlining operational tasks for IT while ensuring corporate data security.

VMware Workspace ONE Access facilitates secure and simplified access to enterprise applications, providing single sign-on capabilities and conditional access based on user authentication. This ensures that users can access the resources they need efficiently while maintaining the security of the organization's data and applications.

Correct Answer: B

One of the prerequisites for installing the Horizon Connection Server is to use a domain user account with administrator privileges on the system. This is because the installer needs to access and modify certain system files and registry settings, as well as create and configure the VMware Horizon View services. The installer also authorizes an Administrators account that has full administration rights for the Horizon environment, including the right to install replicated Connection Server instances. The other options are not prerequisites for installing the Horizon Connection Server. The host system can be a physical or virtual machine, but it must have an IP address that does not change. An SSL server certificate is not required for the initial installation, but it is recommended to replace the default self-signed certificate with a valid certificate from a trusted CA after the installation. AD DS and AD LDS Tools are not required for installing the Horizon Connection Server, but they can be useful for troubleshooting and managing the ADAMdatabase that stores the Horizon configuration data.

Correct Answer: AB

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.

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

To enable a virtual machine to power on with a PCI graphics accelerator, such as a GPU, attached to it, the administrator needs to reserve all guest memory for that virtual machine. This is because PCI devices require direct memory access (DMA) to function properly, and memory overcommitment can interfere with DMA operations. Reserving all guest memory ensures that no memory swapping or ballooning occurs on the virtual machine, and that the memory address space is contiguous and available for DMA56. The other options are not required or valid because: Enabling Video Card 3D Graphics is not necessary for using a PCI graphics accelerator. This option is for using software-accelerated graphics or virtual shared graphics acceleration (vSGA) on a virtual machine7. Setting Memory Shares to High does not guarantee that all guest memory will be reserved. Memory shares only affect how memory resources are distributed amongcompeting virtual machines when there is memory contention on the host. Memory shares do not prevent memory overcommitment or swapping. Disabling CPU Hot Plug does not affect the use of a PCI graphics accelerator. CPU Hot Plug allows adding or removing virtual CPUs from a powered-on virtual machine. It has no relation to PCI devices or DMA operations.

Correct Answer: D

VMware Horizon's Dynamic Environment Manager (DEM) allows for the creation of Horizon Smart Policies with conditions that can be applied based on various criteria, including time of day. By utilizing DEM, an administrator can create policies that restrict certain actions, such as saving data to client devices, outside of specified business hours (5PM to 9AM in this case), thus achieving the desired control over user activities based on the time of day.

Correct Answer: CD

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.

Correct 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.
