In the above diagram, PC1 is connected to a port which is a member of VLAN 2 on the switch and PC2 is connected to a port which is a member of VLAN 3 on the switch. Can PC1 ping PC2?
Explanation
PC1 and PC2 are connected to ports which are members of different VLANs. When PC1 initiates an ARP request to find the mac-address of PC2( since both reside on the same network), the ARP request would not reach PC2, since broadcasts in one VLAN would not be sent to a different vlan. So, though the computers reside on the same network, the communication would not be successful.
Question 9
A network has to be designed for an organization. The organization has 5 departments each of which has different network addresses, which require communication with each other. What strategy and technology can be used for achieving the same?
Explanation
The organization can use a VLAN based network, where different VLANs can be created and mapped with specific IP network addresses of the departments. Inter routing can be configured for communication between the networks. When inter vlan routing is used, just a single interface on the router is required, When VLAN is not used, 5 physical interfaces on the router are required.
Question 10 How does a router forward an IP packet to appropriate destination? Explanation
When a router receives an IP packet, it looks into the destination IP address in it. The router then checks its routing table to look for corresponding routing entries for the network address of the destination IP address. For ex:, if the destination IP
