• Question 431:

  Which of the following situations will occur after multicast load balance is configured? (Select 3 Answers)

  A. If there are no equal-cost unicast routes, multicast load balance will fail to function.
  B. If group address-based load splitting is used, balanced entry distribution over equal-cost routes cannot be ensured because of hash algorithm limitations.
  C. Balanced entry distribution over equal-cost routes can be ensured as long as multicast load balance is configured.
  D. In multicast load splitting, traffic may not be balanced among equal-cost routes. This is because multicast load balance is based on multicast entries but not based on multicast data packets.
