Implementing Cisco IP Routing (CCNP ROUTE, legacy) — Question 117

What does the default value of the EIGRP variance command of 1 mean?

Answer options

• A. Load balancing is disabled on this router.
• B. The router performs equal-cost load balancing.
• C. Only the path that is the feasible successor should be used.

Correct answer:

Explanation

The correct answer is B, as a variance of 1 indicates that EIGRP will only use routes that have equal cost, enabling equal-cost load balancing. Option A is incorrect because load balancing is not disabled; it is simply based on equal costs. Option C is also incorrect, as the default variance allows for the use of multiple equal-cost paths, rather than restricting to only the feasible successor.
