Which statement about a non-zero value for the load metric (k2) for EIGRP is true?

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.

Explanation:
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.
The load is a five minute exponentially weighted average that is updated every five seconds (not
five minutes) .
EIGRP considers the load of an interface only when sending an update for some other reason (like
a link failure)
