Questions about
1.	What is link state ( in OSPF ) ? 2.	Tell me about OSPF. 3.	What process goes in a router when OSPF protocol is initiated in a router, that is, it will go through few states, can you explain it.? 4.	What happens if the process stops at 2nd state – Two way state and how will you trouble shoot it.? 5.	What happens in the Exstart state ? 6.	 If two routers in a LAN segment are connected and OSPF process is started in the routers and if the neighborship is not established, what are the parameters you will look for while trouble shooting ? 7. 	How does the DR election take place? 8. 	What parameter will be taken as the RID ( Router ID ). 9. 	How will you ensure that a particular router is elected as the DR router in a LAN segment ? 10. 	Why OSPF network is organized as areas or hierarchical network? what is the purpose of it ? 11. 	How will calculate the metric COST in OSPF? And in EIGRP ? 12. 	How will you configure the priority to make a router as DR? 13. What are all the tables used by OSPF ? 14. 	What command will you use to display the topology table? 15.	How will found the routes available in a network segment ? 16.	Suppose if a network is not in the routing table, how will you bring it in the routing table.? 17.	What is the syntax for configuring a static route? 18.	Give an example of configuring static route for a device in a segment? 19.	how will you check an interface? What command will you use to see minimum details of interfaces.? 20.	Suppose that if an interface is down due to shutdown command ,	can the line protocol state ( layer 2 ) be up? 21.	Suppose that two routers are connected in a segment and they are running OSPF. Suddenly the neighborship fails and connection is lost. How will you trouble shoot? 22.	Suppose that there are two companies Co-A and Co-B each having their own network. Co-A runs OSPF and has two areas viz: area-0 and area 1. Co-B run another protocol and not OSPF 23.	How good are you in BGP ?

Switching

1.	Which part are you comfortable in Swtiching? 2.	suppose that there are two VLANs. How will the devices in the VLANs communicate? 3.	What is a trunk link.? 4.	What protocols are used in a trunk link.? 5.	How is a frame processed when a VLAN exist in multiple switches and the frame has to go from one device to another device in another switch? 6.	What is a Broadcast storm? 7.	What happens when there is redundant link between two switches?

8.	 How will you cut a broadcast storm? 9.	What is a BPDU frame? 10.	Suppose that there are 4x100Mbps link between two switches and you want to use them. How will accomplish it? 11.	What are the protocols used in Etherchannel ? 12. What causes the FCS errors in a link  increasing?
