To achieve Load Balanced I/O for a specific storage device, it's important to select the appropriate path selection policy that facilitates distributing I/O workload evenly across multiple paths. The correct choice, which is the path selection policy set to Round Robin, is designed specifically for this purpose in VMware environments.

When using the Round Robin policy, the system distributes I/O across all available paths in a sequential manner. This ensures that no single path becomes a bottleneck, as the workload is balanced equally among the paths, enhancing performance and optimizing resource utilization. This method works particularly well in environments where multiple paths are available to a storage device, allowing for improved throughput and redundancy.

In contrast, other options such as the Storage Array Type Policy settings or the MRU (Most Recently Used) path selection policy do not align with the goal of achieving Load Balanced I/O. The MRU policy, for instance, directs all I/O traffic to a single path until it becomes inactive, which does not contribute to load balancing and can lead to performance degradation if that path becomes overloaded or fails. Adjusting the path selection policy to Round Robin directly addresses the need for efficient I/O distribution, making it the most suitable choice for Load Balanced I/O.
