(ii) Egress filtering (Q) Hiding identity of systems
(iii) NAT (R) Keep track of TCP/IP connections
(iv) Stateful firewall (S) Malicious traffic prevention
- A. (i) - (S), (ii) - (P), (iii) - (Q), (iv) - (R)
- B. (i) - (P), (ii) - (R), (iii) - (S), (iv) - (Q)
- C. (i) - (S), (ii) - (R), (iii) - (P), (iv) - (Q)
- D. (i) - (R), (ii) - (Q), (iii) - (S), (iv) - (P)
Answer: A. (i) - (S), (ii) - (P), (iii) - (Q), (iv) - (R)
Explanation: Ingress filtering checks incoming packets to prevent malicious traffic and spoofing from entering the network (S). Egress filtering monitors outbound traffic, serving as a layer of data leakage prevention (P). Network Address Translation (NAT) hides the internal IP identity of systems from the outside world (Q). A Stateful firewall actively tracks the state and context of active TCP/IP connections (R).
