Explanation / Answer

36. On simplifying the address 2001:0000:0000:00fe:0000:0000:abcd:13ef the answer would be 2001:::fe:::abcd:13ef because the leading zeroes are being removed while simplification.In this question there are three colons(:) after 20001 and leading zeroes of fe are being removed then followed by three colons(:).Thus the option A is correct.

37. Ping is computer network software utility that is being used to test the reciever is alive or not. It is generally done by sending ICMP echo request hence option A is correct.

38. Option B is correct as EIGRP(Enhanced Interior Gateway Routing Protocol) is the protocol that is being used for automated routing decisions.Main function of EIGRP is to reduce workload on router and amount of data that needs to send to particular reciever or simply we can say that this protocol can route non-IP packets.

39.In an IPv6 global unicast address the interface id is 64 bit long. As the IPv6 address is 128 bit long. The first 48 bits are site prefix the next 16 bits contain subnet id and the remaining 64 bits contains interface id. Hence option B is correct.

Note : we are required to four parts of a given question.
