Unified Access Gateway (UAG) is a secure gateway appliance that provides access to VMware Horizon based resources such as virtual desktops, RDSH-based applications, and physical Windows machines. UAG supports multiple authentication methods and protocols, such as SAML, OAuth, and RADIUS, to provide secure access to end users from any device and location.UAG also provides edge services such as load balancing, high availability, and firewall rules to optimize the performance and availability of Horizon based resources12.Reference:=1: VMware Horizon Architecture Planning:Unified Access Gateway2: VMware Unified Access Gateway Administration Guide:Introduction to Unified Access Gateway

Correct : 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 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.

Correct : D

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.Reference:=1: VMware Horizon 8 Documentation:VMware vSAN Overview2: VMware Horizon 8 Documentation:Benefits of Using VMware vSAN with Horizon 8

Correct : D

VMware App Volumes is a real-time application delivery system that allows administrators to assign applications to users and groups in Horizon. App Volumes uses virtual disks called packages to store and deliver applications. When a user logs on to a desktop, the App Volumes agent attaches the assigned packages to the desktop and merges them with the OS disk. The user can then access the applications as if they were natively installed.

App Volumes is a suitable solution for deploying an application to specific users in an instant-clone desktop environment with the following characteristics:

The application needs to be updated very frequently: App Volumes allows administrators to update applications in real time by using the update or push-image operations. These operations replace the existing packages with new ones that have the latest updates applied, without affecting the user data or settings. The updated packages are delivered to the users at the next login or refresh.

The application needs to be installed as soon as possible: App Volumes allows administrators to install applications quickly and easily by using a clean packaging system and capturing the application installation process. The resulting package can be assigned to users or groups immediately, without requiring any recomposing or rebooting of the desktops.

The application is not multi-user aware: App Volumes allows administrators to deliver applications that are not multi-user aware by using writable volumes. Writable volumes are user-specific virtual disks that store user-installed applications, data, and settings. Writable volumes can be attached to desktops along with application packages, and they can isolate the user-installed applications from the system-installed applications.

The other options are not suitable for meeting the requirements:

VMware Horizon Published Application: This option allows administrators to publish applications from RDS hosts to users in Horizon. However, this option requires a separate RDS infrastructure and licensing, and it does not support instant updates or writable volumes for user-installed applications.

VMware Dynamic Environment Manager: This option allows administrators to manage user profiles and policies in Horizon. However, this option does not deliver or update applications, and it does not support writable volumes for user-installed applications.

VMware ThinApp: This option allows administrators to package applications into portable executables that can run on any Windows system without installation. However, this option requires a separate packaging process and licensing, and it does not support instant updates or writable volumes for user-installed applications.

Correct : B, D, E

To entitle users and groups to pools, you need to perform the following steps:

During pool creation in the entitlement pane, click on add, search for users and groups in the Active Directory, continue and finish the pool creation.This option allows you to entitle users and groups to a desktop or application pool at the same time as you create the pool3.

Navigate to Inventory > Desktops > check mark a pool > click on Add Entitlement.This option allows you to add entitlements to an existing desktop or application pool after you create the pool4.

Navigate to Users and Groups > Entitlements > click on Entitlements > click on Add Entitlements, search for users and groups in the Users pane and add the desired desktop pool in the next pane Desktop Pools.This option allows you to review and manage the entitlements for users and groups from a single location5.

The other options are not required or valid for entitling users and groups to pools.Running the Active Directory entitlement script in the golden master is not necessary as Horizon 8 automatically synchronizes with Active Directory domains that are configured in Horizon Console6.Specifying the desired Active Directory OU for the VMs during pool creation does not automatically add the preconfigured associated user group to the Horizon entitlements as you still need to select the users or groups from the search results7.Reference:=3: VMware Horizon 8 Documentation:Add Entitlements During Pool Creation4: VMware Horizon 8 Documentation:Add Entitlements After Pool Creation5: VMware Horizon 8 Documentation:Review and Manage Entitlements6: VMware Horizon 8 Documentation:Active Directory Requirements for Horizon Connection Server7: VMware Horizon 8 Documentation:Create an Automated Desktop Pool
