Instant clones are a type of virtual machines that are created by cloning a running parent VM in memory, without requiring a full disk copy. This allows for faster provisioning and updating ofRDS hosts in a farm. Instant clones can be patched in a rolling process with zero downtime by using the push-image operation, which replaces the existing instant clones with new ones that have the latest patches applied. The push-image operation can be performed on a per-farm basis or on multiple farms at once. The push- image operation preserves the user sessions and data on the existing instant clones until they are logged off or disconnected, and then deletes them. The new instant clones inherit the same settings and assignments as the old ones. Therefore, to deploy a RDS farm that can be patched in a rolling process with zero downtime, the administrator should create an instant-clone RDS desktop farm.

Correct Answer: B

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. In this scenario, Adobe Acrobat 11 has been assigned to a user as an App Volumes package. When the user logs on to VM25, which already has Adobe Acrobat 11 natively installed, the App Volumes agent attaches the package to VM25 and creates a shortcut on the user desktop. However, the package does not overwrite or conflict with the natively installed application. Instead, when the user clicks on the shortcut, the App Volumes package for Adobe Acrobat 11 is opened and runs in an isolated environment. This allows the user to use different versions of the same application without affecting each other or the OS. References: App Volumes Architecture and [VMware Horizon 8.x Professional Course]

Correct Answer: D

Collaboration is a feature that allows users to invite other users to join an existing Windows or Linux remote desktop session with both screen sharing and audio out features enabled. A remote desktop session that is shared in this way is called a collaborative session. The user that shares a session with another user is called the session owner, and the user that joins a shared session is called a session collaborator. A Horizon administrator must enable the Session Collaboration feature for the desktop pool or farm that contains the remote desktops that support collaboration. One of the requirements to enable Session Collaboration is to use the VMware Blast display protocol for the remote desktops. VMware Blast is a protocol that provides high- performance, high-quality graphics and multimedia delivery over LAN or WAN networks. VMware Blast supports Session Collaboration by allowing multiple users to view and interact with the same remote desktop session simultaneously. Other display protocols, such as PCoIP or RDP, do not support Session Collaboration and will not allow users to share or join collaborative sessions. Therefore, to enable Session Collaboration in the VMware Horizon environment, the administrator needs to use the BLAST protocol as arequirement.

Correct Answer: A

VMware vCenter Server is the central management component for ESXi servers, allowing administrators to manage multiple ESXi hosts and virtual machines (VMs) from a single console. It provides essential management capabilities, including resource allocation, performance monitoring, and centralized access control, making it the cornerstone for managing a VMware virtualized infrastructure.

Correct Answer: DE

To increase the capacity and resiliency of VMware Horizon desktop pools, deploying Horizon on VMware Cloud on AWS or in a remote data center are viable options. VMware Cloud on AWS provides a scalable and secure cloud platform, allowing for quick expansion and disaster recovery capabilities. Similarly, deploying Horizon in a remote data center can provide geographical diversity, reducing the impact of localized disasters and improving overall resilience.

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.
