a$.$ Explain how this packet is delivered using terms of PC A$,$ B$,$ Switch port$1,$ port$15,$ port$24,$ and router Fa$0.|$

b$.$ This transmission creates two packets. Identify two packets and find source and destination IP and MAC addresses for both packet using given information.

$13.$ Consider the network configuration shownoelow and VLAN information shown below.

Switch $1$: Vlan $10,$ Vlan $20$

Switch $2$: Vlan $10,$ Vlan $20$

Switch $3$: Ylan $10,$ Vlan $20$

Switch $4$: Vlan $10$

a$.$ Draw the network configuration for VLAN $10$ the spanning tree algorithm is running. Which switch is a root?

b$.$ Draw the network configuration for VLAN $20$ the spanning tree algorithm is running. Which switch is a root?
