DURATION: 2 HOURS
Instructions to Candidates: 1. Answer all questions in Section A and Any Other Two questions in Section
SECTION A – ANSWER ALL QUESTIONS IN THIS SECTION (30 Marks)
QUESTION ONE
a) Differentiate between IPV4 and IPV6 addressing systems. (2 Marks)
b) Explain Four benefits of an active directory system. (4 Marks)
c) In today’s world, networks are very important component for any successful business to consider.
However, it’s no longer practical to construct networks by connecting many standalone components
without careful planning and design. Describe four factors that a network designer must consider before
putting up a network. (8 Marks)
d) Vulnerability is a characteristic of a computer or a network system which poses weaknesses to the

networks. Describe four network performance metrics. (4 Marks
SECTION B – ANSWER ANY TWO QUESTIONS IN THIS SECTION
QUESTION TWO (20 MARKS
