Which statement about a non-zero value for the load metric (k2) for EIGRP is true? Select
the best response.
A.
A change in the load on an interface will cause EIGRP to recalculate the routing metrics
and send a corresponding update out to each of its neighbors.
B.
EIGRP calculates interface load as a 5-minute exponentially weighted average that is
updated every 5 minutes.
C.
EIGRP considers the load of an interface only when sending an update for some other
reason.
D.
A change in the load on an interface will cause EIGRP to recalculate and update the
administrative distance for all routes learned on that interface.

The load metric (k2) represents the worst load on a link between source and destination.
EIGRP routing updates are triggered only by a change in network topology (like links, interfaces go up/down, router added/removed), and not by change in interface load or reliability -> A & D are not correct.
The load is a five minute exponentially weighted average that is updated every five seconds (not five minutes) -> B is not correct.
EIGRP considers the load of an interface only when sending an update for some other reason (like a link failure, topology change). Updates are not sent out each time the load changes -> C is correct.
