SG0-001 · Question #357
A server has two HBAs each connected to redundant fabrics. The fabrics have multiple connections to the storage targets. Which of the following is true?
The correct answer is C. Multipathing will provide high availability. This configuration utilizes multiple HBAs and redundant fabrics to ensure continuous access to storage, where multipathing software actively manages these redundant paths.

Why each option
This configuration utilizes multiple HBAs and redundant fabrics to ensure continuous access to storage, where multipathing software actively manages these redundant paths.
Multipathing is designed precisely for configurations with redundant paths, like the one described, to manage and utilize them effectively for fault tolerance and performance.
Multipathing software is specifically designed to manage multiple physical paths between a server and its storage, providing load balancing and automatic failover. In this configuration, if one HBA, fabric, or storage path fails, multipathing ensures that I/O operations can continue over the remaining paths, thus achieving high availability.
