Show answer & explanation
Correct answer: B. A-III, B-II, C-IV, D-I
Explanation
SMTP (Simple Mail Transfer Protocol) is an application-layer protocol used for email, so A-III. UDP (User Datagram Protocol) operates at the transport layer, so B-II. Ethernet is a data-link-layer (LAN/MAC) technology, so C-IV. IP (Internet Protocol) is a network-layer protocol responsible for addressing and routing, so D-I. This gives A-III, B-II, C-IV, D-I, which is option (2).More Data Communication and Computer Networks questions
