CompTIA Network+ N10-009 (V9) Practice Question

EIGRP's ability to support unequal-cost load balancing allows the protocol to use multiple paths of different metrics to the same destination, unlike protocols that support only equal-cost paths. This extends the capability of a network by using all viable paths effectively, increasing bandwidth and redundancy without compromising the routing efficiency.

The incorrect answers referenced methods that are either not directly linked to EIGRP's advanced capabilities (like basic split horizon) or are benefits of EIGRP that do not address the specific capability of unequal-cost load balancing - speed (not a unique feature of using this type of load balancing) or metrics simplification (which is related broadly to how EIGRP calculates path costs but not specifically to the benefit of unequal-cost load balancing).
