Answer:A
The _________ field determines the lifetime of IPv6 datagram
A. Hop limit B. TTL C. Next header D. Type of traffic
Explanation: The Hop limit value is decremented by one by a router when the datagram is forwarded by the router. When the value becomes zero the datagram is discarded. The field is 8-bits wide, so an IPv6 packet can live up to 255 router hops only.
