Which two statements about EIGRP load balancing are true? (Choose two)
A . Cisco Express Forwarding is required to load-balance across interfaces
B . A path can be used for load balancing only if it is a feasible successor
C . EIGRP supports unequal-cost paths by default
D . Any path in the EIGRP topology table can be used for unequal-cost load balancing
E . EIGRP supports 6 unequal-cost paths

Answer: B E

Explanation:

EIGRP provides a mechanism to load balance over unequal cost paths (or called unequal cost load balancing) through the “variance” command. In other words, EIGRP will install all paths with metric < variance * best metric into the local routing table, provided that it meets the feasibility condition to prevent routing loop. The path that meets this requirement is called a feasible successor. If a path is not a feasible successor, it is not used in load balancing.

Note: The feasibility condition states that, the Advertised Distance (AD) of a route must be lower than the feasible distance of the current successor route.
