Explanation
Answer: B - The default path selection policy for ALUA (Asymmetric Logical Unit Access) storage arrays is Fixed AP. Fixed AP is an extension of the Fixed path selection policy and brings additional intelligence to the process. ALUA allows a host to “see” a LUN through both storage controllers, but only one of the paths is optimal.
