Designing Cisco Enterprise Networks (ENSLD) — Question 67

Which two routing protocols allow for unequal cost load balancing? (Choose two.)

Answer options

• A. EIGRP
• B. IS-IS
• C. BGP
• D. OSPF
• E. RIPng

Correct answer: A, C

Explanation

EIGRP and BGP are the only routing protocols listed that enable unequal cost load balancing. EIGRP uses the concept of variance to allow this feature, while BGP can utilize multiple paths with different costs. IS-IS, OSPF, and RIPng do not support unequal cost load balancing, as they typically balance traffic only across equal-cost paths.
