Show answer & explanation
Correct answer: A
Ingress filtering is primarily designed to prevent malicious traffic from entering a network, matching (i) with (S). Egress filtering monitors outgoing data flows to prevent unauthorized information exfiltration, linking (ii) with (P). NAT masks internal IP addresses to hide system identities from external networks, connecting (iii) with (Q). Finally, stateful firewalls maintain connection state tables to track TCP/IP sessions, associating (iv) with (R).
