Examine the LUN properties that are shown in the exhibit. Which action should be taken to utilize all active paths?
The correct answer is D. Change PSP to Round Robin. To utilize all active paths on a LUN, the Path Selection Policy must be set to Round Robin, which actively distributes I/O across every available path simultaneously.

Why each option
To utilize all active paths on a LUN, the Path Selection Policy must be set to Round Robin, which actively distributes I/O across every available path simultaneously.
Most Recently Used PSP only sends I/O down the single most recently active path and does not switch to other paths unless the current one fails, leaving additional active paths idle.
Without Round Robin configured, the current PSP is only utilizing one preferred path at a time, meaning not all active paths are being used simultaneously.
Fixed PSP designates one preferred path for all I/O and only fails over to alternate paths when the preferred path is unavailable, leaving all other active paths unused during normal operation.
Round Robin PSP cycles I/O requests across all active paths in turn, ensuring every available path carries traffic and maximizing throughput. Unlike other PSPs that designate a single primary path, Round Robin treats all active paths equally and uses them concurrently. This is the only PSP that fully utilizes all active paths as the question requires.
