Correct answer: C
Correct matching: I -> a, II -> c, III -> d, IV -> b
I. Proxy Server -> Firewall: Proxy servers act as intermediaries and are often used for filtering and access control at the application layer, providing firewall-like functionality.
II. Kazaa, DC++ -> P2P: These are peer-to-peer file-sharing applications, so they match the P2P entry.
III. SLIP -> PPP: SLIP (Serial Line Internet Protocol) and PPP are both serial point-to-point protocols; SLIP is an older serial-line IP protocol and is best associated with the PPP entry.
IV. DNS -> Caching: DNS servers cache name-to-address mappings to speed up name resolution, so DNS best matches caching.
Therefore the correct option lists: I-a, II-c, III-d, IV-b.
