Problem 2 What is the difference between a switch and a hub? Use the Packet tracer to prove this. (Hints: Use the simulation mode in Packet Tracer to watch packets going through a switch and a hub.) Problem 3 a) Describe the spanning tree algorithm. b) Define the root/designated/blocked port? c) In the Fig.2, which switch will be the root and which ports are blocked? Please explairn your choice. (Hints: You can simulate this on Packet tracer and answer this question by applying the STP algorithm.) Fa01 Fa0r3 0000 0C46 A762 swo SW2 Fa0/2 Fa0r2 0001.9718 4310 Fig. 2. Network with 3 switches
