(b) User Datagram Protocol
(c) Internet Control Message Protocol
(d) Dynamic Configuration Protocol
5) Computers that store network software and shared or private user files are known as: 1 mark
(a) Workstations
(b) Mainframes
(c) Servers

(d) None of the above
7) A network protocol that takes an IP address in an IP datagram and translates it into the appropriate medium access control layer
address for delivery on a local area network is referred to as: 1 mark
(a) The Internet Protocol
(b) The Address Resolution Protocol
(c) The Dynamic Host Configuration Protocol

Section B
1) State and briefly explain the four statistics or measures that are useful in evaluating networks. 8 marks (2,2,2,2)
2) State the three major advantages of the star topology. 3 marks
3) Differentiate between a node and a network interface card. 2 marks
4) State and briefly explain the four key elements of an SNMP. 8 marks(2,2,2,2)
5) A network with bandwidth of 10 Mbps can pass only an average of 12,000 frames per minute
with each frame carrying an average of 20,000 bits. What is the throughput of this network? 2 marks
6) What are the propagation time and the transmission time for a 15-Mbyte message (an image) if the
bandwidth of the network is 1 Mbps? Assume that the distance between the sender and the
receiver is 24,000 km and that light travels at 2.4 x 108 m/s. 4 marks
