Explain how the SR bridge notifies if the receiving packet contains route information.

Following shows the destination and source address of receiving frame. Indicate if each packet contains route information or not.

$3.$ SR bridge receives a packet containing rout information of $"101101101001110110000110100110010011011010010000"$ Find the LAN numbers the packet will travel based on route information.

$4.$ Compare the source routing bridging and transparent bridging in terms of overhead and easy of configuration.

$5.$ What are the benefits of link aggregation?

$6.$ One link is involved in link aggregation and it is configured to use LACP. One end port was configured in passive mode while the other port was configured in passive mode as well. Explain what will happen and why$-$

$7.$ One of the advantages of using Virtual LAN is security. Explain why.

$8.$ Explain what is "Trunking" and why it needs.

$9.$ VLAN tag is used in $802\mathrm{.}10.$ Explain what VLAN tag is for.

$10.$ Discuss the difference between $802\mathrm{.}1Q$ and ISL.

$11.$ Explain where the VLAN tag is inserted and removed.

$12.$ Consider below figure where PC A is in VLAN $10$ and PCB is in VLAN $20$ and the transmission from PC A to B$.$
