An auditor needs to verify that no interface on a Linux server has a netmask other than /24. The auditor's Python script currently uses psutil.net_if_addrs(). Which field from the returned tuples should the script examine?

The 'family' field of each address tuple

The 'broadcast' field of each address tuple

The 'ptp' field of each address tuple

The 'netmask' field of each address tuple

A Python tool must retrieve the MAC address of a network interface on both Windows and Linux. The tool can use third-party libraries. Which library provides a cross-platform way to get MAC addresses?

psutil.net_if_addrs() with AF_LINK

A Python script needs to determine if any network interface is down on a Linux host. The script can use third-party libraries. Which code snippet correctly identifies interfaces that are down?

import os; down = [name for name in os.listdir('/sys/class/net') if not os.path.exists('/sys/class/net/' + name)]

import socket; down = [name for name, _ in socket.if_nameindex() if name not in socket.if_nameindex()]

import subprocess; down = subprocess.check_output(['ip', 'link']).decode().split()

import psutil; stats = psutil.net_if_stats(); down = [name for name, stat in stats.items() if not stat.isup]
