What deployment method will expedite OS installations for 1,000 servers?

Using PXE boot to retrieve an image is the most efficient method for deploying operating systems across a large number of servers, such as 1,000. PXE, or Preboot Execution Environment, allows servers to boot from a network interface before the actual operating system is loaded from local storage. This method leverages a network server to provide the system image over the network, streamlining the installation process significantly.

The benefits of PXE boot include the ability to maintain a single, centralized image that can be updated in one location rather than needing to update multiple physical media such as USB drives or disks. This not only simplifies management but also ensures that every server has the same configuration and installed software, reducing inconsistencies and errors.

Additionally, PXE booting eliminates the need for physical handling of media, which is particularly advantageous when dealing with a large number of installations, as it reduces the time and labor required. It also allows simultaneous installations across multiple servers, further speeding up the deployment process.

In contrast, methods like using disk duplicating software or USB disk images may still require physical media management and could lead to longer setup times, whereas a disk replicator, while efficient, still does not match the network-based efficiency provided by PXE. Therefore,
