An enterprise is experiencing transmission errors and excessive delays over their WAN when backing up user workstations. A systems architect decided to resolve the problems by centralizing data storag

Virtual Desktop Infrastructure (VDI) centralizes user desktops, applications, and data within the data center, significantly reducing the amount of data transmitted over the WAN for tasks like backups. Instead of backing up individual workstations across the WAN, backups can be performed locally within the data center, mitigating transmission errors and excessive delays.

RAS (Remote Access Service) allows remote users to access network resources but does not inherently centralize processing or resolve WAN backup issues directly.

VDC (Virtual Data Center) refers to a virtualized pool of compute, storage, and networking resources but is a broader concept of data center virtualization, not a direct solution for centralizing user workstations to improve WAN backup performance.

QoS (Quality of Service) helps prioritize traffic over the WAN but does not reduce the overall volume of data that causes transmission errors and delays for large backups.
