An administrator has just enabled multi-path connectivity to a storage array, but the host can only detect a single path. The switches detect both HBA ports. Which of the following fabric components i

If the host was plugged into the wrong switch port, the switches would likely not detect both HBA ports as stated in the question.

Zone configuration in a Fibre Channel SAN dictates which initiators (HBAs) can communicate with which targets (storage array ports). If zones are incorrectly configured or not applied, one path might be allowed while the other is blocked, preventing the host from seeing all intended paths despite the physical connections being up.

If host fiber or SFPs were faulty, the switches would not detect both HBA ports, or the link would be down.

Busy ISLs (Inter-Switch Links) would cause performance issues or congestion, not prevent path detection; the paths would still be visible to the host.
