A. 3
B. 4
C. 5
D. 6

6. Which of the following are used to tell the underlying routers how to efficiently process the packet and route it?
A. Traffic class
B. Flow label
C. Both A and B
D. Can not say

7. The header length of an IPv6 datagram is ___________
A. 10bytes
B. 25bytes
C. 30bytes
D. 40bytes
View Answer
Ans : D
Explanation: IPv6 datagram has fixed header length of 40bytes, which results in faster processing of the datagram. There is one fixed header and optional headers which may or may not exist. The fixed header contains the mandatory essential information about the packet while the optional headers contain the optional “not that necessary” information.
8. In the IPv6 header, the traffic class field is similar to which field in the IPv4 header?

B. Fast-switching
C. ToS field
D. Option field
View Answer
Ans : C
Explanation: The traffic class field is used to specify the priority of the IP packet which is a similar functionality to the Type of Service field in the IPv4 header. It’s an 8-bit field and its values are not defined in the RFC 2460.
9. Which among the following features is present in IPv6 but not in IPv4?
A. Fragmentation
B. Anycast address
C. Header checksum
D. Options
View Answer
Ans : B
Explanation: There is an anycast address in IPv6 which allows sending messages to a group of devices but not all devices in a network. Anycast address is not standardized in IPv4.
10. According to an estimate, 1564 addresses can be allocated to every square meter of this earth.
