Refer to the Exhibit

Refer to the exhibit. A customer has these availability requirements: loss of one controller with stateful failover and without impact on wireless client connectivity loss of one core switch without loss of connectivity for any endpoints or APs in the building loss of any one switch-to-switch or MC-to-switch link without loss of connectivity for any endpoints or APs in the building and with minimal impact on infrastructure functionality loss of any one access switch with minimal impact to wireless client connectivity The exhibit shows the current plan for the topology. Which change should the architect make to the plan to provide better support for the customer availability requirements?

A) Use two 40GbE DACs for the VSF link between the core switches.
B) Add VLANs 11 and 15 to the MC connections to ensure both MCs can manage any of the APs.
C) Add 120 additional AP licenses, so that each MC can support all the APs even if the other MC fails.
D) Change the 40GbE DAC on the 5406R switch to a stacking cable with stacking module.
