An administrator needs to deploy 1,000 servers in a short period of time. Which of the following deployment methods will expedite the OS installations?

Disk duplicating software requires physical access to each individual machine to connect drives, making it impractical and slow for 1,000 servers.

USB disk images require manually inserting a USB drive into each server one at a time, which cannot scale to 1,000 units quickly.

A disk replicator duplicates drives via direct physical connection one at a time, making large-scale simultaneous deployment impossible.

PXE (Preboot Execution Environment) boot allows servers to contact a central deployment server over the network at startup and pull a complete OS image, enabling fully automated, parallel provisioning of all 1,000 servers. No physical media insertion or per-server interaction is required, making it the industry-standard method for rapid large-scale server deployments using services like Windows Deployment Services (WDS).
