It uses logical addressing (e.g., IP addresses) to determine the best path for data transmission, managing packet forwarding, routing, and addressing.Question 2: Which of the following IP address classes is used for multicast addressing?A) Class AB) Class BC) Class CD) Class DCorrect Answer: D) Class DExplanation: Class D IP addresses are reserved for multicast groups, which are used to send data to multiple hosts simultaneously. These addresses range from 224.0.0.0 to 239.255.255.255.Question 3: Which routing protocol is known for using a link-state algorithm to determine the shortest path?A) RIPB) BGPC) OSPFD) EIGRPCorrect Answer: C) OSPFExplanation: OSPF (Open Shortest Path First) is a link-state routing protocol that uses the Dijkstra algorithm to calculate the shortest path to each network. It is more efficient and scalable than distance-vector protocols like RIP.
