Which three statements are true regarding EIGRP? (Choose three.)
A.
By default, EIGRP performs auto-summarization across classful network boundaries.
B.
EIGRP uses an area hierarchy to increase network scalability.
C.
To speed convergence, EIGRP attempts to maintain a successor and feasible successor path
for each destination.
D.
EIGRP uses hellos to establish neighbor relationships.
E.
By default, EIGRP uses the Dijkstra algorithm to determine the best path to a destination
network based on bandwidth and delay.
