An administrator is configuring a new Linux server and wants to boot the system to a file that was previously downloaded to locally install removable media. Which of the following boot options…

PXE (Preboot eXecution Environment) is used for network booting, where the system fetches its boot image and installation files over a network, not from local removable media.

An ISO file is a disk image that contains a complete copy of a file system, commonly used for installing operating systems. When an ISO is placed on removable media like a USB drive or DVD, the system can be configured to boot directly from this media, enabling a local operating system installation.

NFS (Network File System) is a protocol for accessing files over a network, but it is not a direct boot option for installing an OS from local removable media.

HTTP (Hypertext Transfer Protocol) is primarily used for retrieving web resources and is not a boot option for directly loading an OS from local removable media.
