Ans 36. The type of router will be :
Option 1.DNS router as they do not work in hierarchical OSPF.
Ans 37. Open,update and keepalive are messages of BGP
So Answer will be Option 2,Routing.
Ans 38. This runs directly on top of IP ,so Option 3 is correct.
Ans 39. IP address 4 byte means 32 bits, It has both network and host part.
Option 3 is correct.
Ans 40. Option 3 will be the answer, as Channel coding is not done by data link ,it is done by physical layer and tasks in the other options are performed by data link layer.
