The Microsoft Deployment Toolkit (MDT) is a tool for automating operating system and application deployment. However, MDT itself does not have native capabilities for network booting (PXE) or multicasting deployment images. To enable these features, MDT must be integrated with Windows Deployment Services (WDS). WDS is a server role in Windows Server that provides the necessary infrastructure, including a PXE server to boot clients over the network and a transport server that supports multicasting. By using WDS with MDT, you can efficiently deploy a single image file to multiple computers simultaneously, which is the core of multicast deployment.

A. Multipath I/O (MPIO) is a storage fault-tolerance and performance-enhancement technology that provides redundant paths to storage devices. It is unrelated to network image deployment.
B. Multipoint Connector is a component of Windows MultiPoint Server, a solution that allows multiple users to share a single computer. It is not used for OS deployment.
D. Windows Server Update Services (WSUS) is a server role used to manage and distribute software updates from Microsoft to computers on a network, not for deploying operating system images.

Section: "Prepare the Windows Deployment Services (WDS) server role"

Content: This official MDT documentation explicitly states

"Even though MDT can be used for Lite Touch deployments without WDS

if you want PXE boot support

you need to use WDS." It further details the steps to install and configure WDS for use with MDT

which is a prerequisite for network-based deployments like multicast.

Section: "Multicast deployments"

Content: This document describes the multicast functionality inherent to Windows Deployment Services. It explains

"By using multicast functionality

you can deploy an image to a large number of client computers without overburdening the network." This confirms WDS is the correct technology for multicast.

Section: "Overview"

Content: This document defines MPIO as a framework to "provide a high-availability solution for storage." This confirms its purpose is related to storage redundancy

not OS deployment.
