Final answer:
Yes, IPv6 uses the same Administrative Distance (AD) system as IPv4. AD is a router metric for selecting the best path and is not dependent on the IP version.
Step-by-step explanation:
Does IPv6 use the same AD system as IPv4?
The question pertains to whether IPv6 and IPv4 use the same AD (Administrative Distance) system. Administrative Distance (AD) is a metric used by routers to choose the best path when there are multiple paths to the same destination from two different routing protocols.
The correct answer to this question is: a. Yes, IPv6 uses the same AD system as IPv4. Although IPv6 and IPv4 are two different versions of the Internet Protocol, the concept of Administrative Distance is not dependent on the IP version being used. Thus, the AD system is equally applicable and functionally similar across both IPv4 and IPv6.
