An administrator needs to deploy 1000 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 server to connect and run the duplication process, making it impractical for 1000 servers in a short timeframe.

USB disk images require a technician to physically insert the USB drive into each server and initiate the install, which does not scale efficiently to 1000 machines.

A disk replicator is a hardware device that copies drives one at a time and requires physical handling of each drive, making it unsuitable for rapid large-scale deployment.

PXE (Preboot Execution Environment) boot allows servers to retrieve an OS image from a central deployment server over the network before any local OS is loaded. This eliminates the need for physical media at each machine and enables fully automated, simultaneous deployment to thousands of servers, dramatically reducing deployment time at scale.
