Q
The _________ field determines the lifetime of IPv6 datagram
AA. Hop limit
BB. Ttl
CC. Next header
DD. Type of traffic
Correct Answer:
A. A. Hop limit
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.
