Which statement about Omnissa Horizon workloads is correct?

The correct answer is A. Omnissa Unified Access Gateway is the edge access component used with Horizon to provide secure remote access from an external network to internal Horizon desktops and applications. It is commonly positioned in a DMZ and avoids exposing internal Horizon infrastructure directly to external users. Omnissa documentation describes Unified Access Gateway as enabling secure remote access from external networks to Workspace ONE and Horizon resources, and Horizon installation guidance describes it as the default gateway for secure access to remote desktops and applications from outside the corporate firewall. Option B is incorrect because Horizon support is not limited to a minimum of more than 720 desktops, nor is it only supported through a generic HPE Compute qualification. Option C is technically wrong because Horizon can use supported VMware datastore types such as VMFS, NFS, and vVols depending on the validated design. Option D is also wrong because GPU resources are required only for graphics-accelerated use cases, not for every Horizon cluster.
