Implementing Cisco IP Routing (CCNP ROUTE, legacy) — Question 31

A network engineer is considering enabling load balancing with EIGRP. Which consideration should be analyzed?

Answer options

• A. EIGRP allows a maximum of four paths across for load balancing traffic.
• B. By default, EIGRP uses a default variance of 2 for load balancing.
• C. EIGRP unequal path load balancing can result in routing loops.
• D. By default, EIGRP performs equal cost load balancing at least across four equal cost paths. D

Correct answer:

Explanation

The correct answer is D because EIGRP is designed to perform equal cost load balancing among multiple paths, ensuring traffic is distributed evenly. Option A is incorrect as EIGRP can actually support up to 16 load balanced paths. Option B is misleading since the default variance can be adjusted, although it typically starts at 1. Option C is also inaccurate, as EIGRP is designed to prevent routing loops even with unequal path load balancing.
