Dell EMC Exam E20-526 Topic 2 Question 39 Discussion

The queue depth is perLUN, and not perinitiator. Here there are 64 LUNs, each visible through 4 paths, which would indicate that 256 is a good choice for the queue depth setting.

Note: As a general advice, for optimal operation with XtremIO storage, consider the following: Set the queue depth to 256.
