VMware Horizon's Dynamic Environment Manager (DEM) is designed to provide a consistent and personalized desktop experience for users across different sessions and desktops. DEM manages user profiles and policies dynamically, ensuring that user settings, preferences, and application configurations are consistent no matter which desktop a user connects to, thus meeting the requirement for a uniform desktop experience.

In VMware Horizon, the Pre-Launch feature allows for the initiation of applications immediately after user authentication, reducing the launch time of frequently used applications. By editing the application pool settings and enabling the Pre-Launch option, administrators can improve user experience by having critical applications ready as soon as the authentication process is completed.

Access groups are a way of organizing and delegating the administration of machines, desktop pools, application pools, and farms in Horizon. By default, all these objects reside in the root access group, which appears as / or Root (/) in Horizon Console. A high-level administrator can create sub-access groups under the root access group and assign different permissions to different administrators for each access group. For example, a high-level administrator can create an access group called RDS Farms and assign the Inventory Administrators role to a junior-level administrator for that access group. This way, the junior-level administrator can see and manage all the RDS farms that are in the RDS Farms access group, but not the ones that are in other access groups or the root access group. Therefore, to correct the issue of a junior-level administrator not being able to see all RDS farms, a high-level administrator needs to make changes to the access groups and the permissions associated with them. References: Understanding Permissions and Access Groups and [VMware Horizon 8.x Professional Course]

To access the settings and status of a pool in VMware Horizon, an administrator would navigate to the Inventory > Desktops section of the Horizon Console. By selecting a specific pool, the administrator can view detailed information in the Summary section, including Pool Settings and the status of the image used during the pool's deployment, providing insights into the pool's configuration and operational status.

VMware vSAN is a storage product that allows the pooling of resources to create datastores in a software defined datacenter. VMware vSAN is a hyper-converged infrastructure solution that integrates compute, storage, and networking resources on industry-standard x86 servers. VMware vSAN aggregates local or direct-attached data storage devices to create a single storage pool shared across all hosts in the vSAN cluster. VMware vSAN enables you to provision and manage storage from the VMware vSphere Web Client or the VMware vCenter Server Appliance Shell. VMware vSAN provides several benefits, such as lower total cost of ownership, simplified management, high performance, scalability, and availability12. References := 1: VMware Horizon 8 Documentation: VMware vSAN Overview 2: VMware Horizon 8 Documentation: Benefits of Using VMware vSAN with Horizon 8

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 among competing 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.

Single sign-on (SSO) is a feature that allows users to log in to Horizon Client once and launch remote desktops and applications without being prompted for credentials again. SSO is enabled by default and can be configured in the Global Settings of Horizon Administrator. One of the settings is SSO Timeout, which determines how long the user’s credentials are cached before they expire. If the SSO Timeout is too short, users might be frequently asked for credentials when opening additional apps. To resolve this issue, the administrator can increase the SSO Timeout value or set it to -1, which means that no SSO timeout limit is set. References: Global Settings for Client Sessions in Horizon Console and [VMware Horizon 8.x Professional Course]

To expand a Writable Volume in VMware Horizon, the administrator needs to navigate to the Volumes > Writables section in the Horizon Console, select the specific volume, and choose the option to update or expand the writable volume. The new size specified must be at least 1GB larger than the current size to ensure there is enough space for the expansion process and to accommodate the growth of user data.
