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-up convergence, EIGRP attempts to maintaina 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.
