Correct Answer: A

Question 12

Which of the following situatbns will occur when the command multicast bad balance" is
configured? (Select 3 answers)

A. If group address-based load splitting is employed, balanced distribution of entries over equal-cost routes cannot be ensured due to hash function limitations. B. Balanced distribution of entries over equal-cost routes can be ensured as long as multicast load balancing is performed. C. If there exists no unicast equal-cost routes, multicast load balancing fails. D. During multicast load splitting, traffic may not be balanced among equal-cost routes because multicast load balancing is based on multicast entries not multicast data packets.
