A system administrator needs to install an operating system onto a new server in a remote location using PXE. Which of the following methods will BEST accomplish this?

SSH requires an existing OS and running SSH daemon on the target system, which a bare-metal server being provisioned via PXE does not have.

RDP is a graphical remote desktop protocol that requires a fully installed and running Windows OS, making it unusable for bare-metal provisioning.

PXE (Preboot Execution Environment) relies on TFTP (Trivial File Transfer Protocol, port 69) to deliver the initial bootstrap program and kernel image to the client before any OS is loaded, making TFTP the required protocol for remote PXE-based OS installations.

HTTP is not part of the standard PXE boot process; while some advanced environments like iPXE can use HTTP, standard PXE relies on TFTP for the initial bootstrap.
