Consider the routing protocols given in List-I and the names given in List-II:
| List - I | List - II | ||
|---|---|---|---|
| (i) | Distance vector routing | (a) | Bellman-Ford |
| (ii) | Link state routing | (b) | Dijkstra |
For matching of items in List-I with those in List-II, which ONE of the following options is CORRECT?
A machine receives an IPv4 datagram. The protocol field of the IPv4 header has the protocol number of a protocol X .
Which ONE of the following is NOT a possible candidate for X ?
Consider a network that uses Ethernet and IPv4. Assume that IPv4 headers do not use any options field. Each Ethernet frame can carry a maximum of 1500 bytes in its data field. A UDP segment is transmitted. The payload (data) in the UDP segment is 7488 bytes. Which ONE of the following choices has the CORRECT total number of fragments transmitted and the size of the last fragment including IPv4 header?
Suppose we are transmitting frames between two nodes using Stop-and-Wait protocol. The frame size is 3000 bits. The transmission rate of the channel is 2000 bps (bits/ second) and the propagation delay between the two nodes is 100 milliseconds. Assume that the processing times at the source and destination are negligible. Also, assume that the size of the acknowledgement packet is negligible. Which ONE of the following most accurately gives the channel utilization for the above scenario in percentage?
