Explanation
PXE (Preboot Execution Environment) is the firmware feature that allows a computer to boot from a network interface rather than a local disk. It must be explicitly enabled in the system BIOS/UEFI settings and set as a boot priority option. If PXE is not enabled, the NIC will never attempt to contact an imaging server regardless of network connectivity. A failed CMOS battery (A) would cause date/time issues, not a specific boot failure. A faulty NIC (B) or bad cable (D) would be lower probability causes compared to a configuration issue, and the question implies the network connection itself works fine.
