Which of the following statements are true? (a) The fragmentation fields in the base header section of IPv4 have moved to the fragmentation extension header in IPv6. (b) The authentication extension header is new in IPv6. (c) The record route option is not implemented in IPv6.

Which of the following statements are true? (a) The fragmentation fields in the base header section of IPv4 have moved to the fragmentation extension header in IPv6. (b) The authentication extension header is new in IPv6. (c) The record route option is not implemented in IPv6. Correct Answer (a), (b) and (c)

The correct answer is option 4.

Key Points

  • In IPv6, the fragmentation fields from IPv4's base header segment have been transferred to the fragmentation extension header, and hence the given statement is right.
  • Both IPv4 and IPv6 have the same authentication header, but IPv6 has a new authentication extension header. As a result, the given statement is right.
  • The record route function is not specified in the IPv6 specifications, and the record route function in IPv4 is less versatile and has scalability issues. As a result, the given statement is right.

Hence the correct answer is (a), (b) and (c).

The following is a map showing a route for a cycle race. The route starts and goes 12 km East, then there is a turn towards North where the route goes on for 5 km, then there is a turn towards East where the route goes on for 11 km, then there is a right turn from where the route goes on 5 km to reach the end.
