Which of the following allows an organization to provide remote desktop resources without providing physical workstations to its users?

Virtual Desktop Infrastructure (VDI) is a technology that hosts desktop operating systems on a centralized server in a data center. Users connect to their desktop instances remotely using a network connection from a thin client or any other endpoint device. This model allows an organization to provide a full desktop experience to users without issuing them individual physical workstations, as all the processing and data storage occurs on the central server. This centralizes management, improves security, and supports remote work.

A. RMM (Remote Monitoring and Management) is software used by administrators to manage existing physical or virtual endpoints, not to provide them.
B. SaaS (Software as a Service) delivers specific software applications over the internet, not a complete desktop operating system.
D. Containers are a lightweight virtualization method for deploying and running applications in isolated environments, not for providing interactive desktop sessions to users.

While not defining VDI directly, it defines the service models. VDI is a primary example of Desktop as a Service (DaaS), a cloud service where a virtual desktop is delivered to a user.

- VMware, Inc. (n.d.). What is VDI (Virtual Desktop Infrastructure)?. Official vendor documentation from VMware, a leading VDI provider, defines VDI as "the hosting of desktop environments on a central server." It explicitly states this is a form of desktop virtualization.

This foundational paper on cloud computing discusses virtualization as a key enabling technology, the principles of which are applied in VDI to abstract the desktop OS from the physical hardware.
