A security analyst needs to inventory all active network interfaces on a mixed fleet of Windows and Linux servers. The script must run without installing third-party packages and must report the interface name and its IPv4 address. Which approach should the analyst use?

Use the netifaces library, which is included in the Python standard library

Use the standard library's socket and platform modules to call platform-specific commands like ipconfig and ip, then parse the output

Use psutil.net_if_addrs() and psutil.net_if_stats() to list interfaces and filter for those that are up

Use socket.getaddrinfo() with an empty hostname to enumerate all interfaces

When using `psutil.net_if_addrs()` on different operating systems, what is a key difference in the returned data?

The function returns different data types on different platforms

The function returns a list of interface names only

The function only works on Linux

The address family for MAC addresses may be AF_LINK on some platforms and AF_PACKET on others

A developer is writing a Python script that must run on both Windows and Linux to enumerate network interfaces. The script should use only the standard library. Which code snippet correctly lists interface names on both platforms?

import os; print(os.listdir('/sys/class/net'))

import socket; print(socket.if_nameindex())

import netifaces; print(netifaces.interfaces())

import subprocess; print(subprocess.check_output(['ipconfig']))
