Question 1

Which of the following descriptions about UItrapath multipath settings are correct? (Multiple Choice)

A. The load balancing mode includes the polling algorithm, the maximum queue depth algorithm, and the maximum task algorithm. B. When the multipath detects that the preferred controller has recovered from the fault, it will continue to deliver I/O to the preferred controller immediately by default. C. When the connection between the LUN's owning controller and the host is interrupted, the host accesses the LUN through the peer controller, and the multipathing software will switch the LUN's owning controller to the peer controller by default. D. The working mode of the array can be load balancing within the controller or load balancing between controllers.
