The best answer is D because Serial Attached SCSI is designed for enterprise environments where reliability, throughput, and path redundancy matter. The scenario describes dual-controller style resilience and continued availability if one path fails, which points to multipath-capable storage connectivity rather than a simpler desktop-oriented interface. CHFI v11 includes disk interfaces and storage concepts under digital evidence fundamentals, so candidates are expected to distinguish enterprise forensic workstation and server storage characteristics from ordinary consumer storage. SATA is common and cost-effective, but it does not match the same level of enterprise redundancy and controller-path resilience suggested here. PCIe is a bus architecture used by devices such as NVMe storage, but it is not the disk interface concept being tested in this option set. Traditional parallel SCSI is older and less aligned with the modern rack-mounted, high-availability context described. SAS supports robust enterprise drive connectivity, simultaneous communication behavior, and high-availability storage designs, which makes it the strongest fit for a forensic recovery workstation that must maintain dependable access even when one path or controller encounters a problem.
