Question 1
a) Compare and contrast between the functionality, pros and cons of Layer 2 (bridging) and Layer 3 (pure routing) LAN switches.
[10 marks]
b) Illustrate using diagrams to describe the functionalities of common Layer 2 switches (Store-and-Forward and Cut Through) and Layer 3 switches (Pure Routers).
[15 marks]
c) Describe the functionality of Spanning Tree algorithm and explain the benefits of implementing such algorithm.
[9 marks]
d) Designing a medium-sized switched LAN:
This case study is to design a switched LAN that spans two buildings. Each building will contain about 500 end users and a series of servers and other common resources.
i) Building 1 – Core and Centralized Resources Areas design
Building 1 contains 500 end users, of which 300 are to be attached to MicroLAN and 200 are to receive dedicated switch ports. Within the...
