After one of two FC HBAs had been replaced due to a failure, the storage administrator notices that performance has not returned to normal levels. Which of the following is the MOST likely cause for t

While possible, a faulty new HBA is less likely to cause partial performance degradation compared to a configuration issue like outdated zoning, especially if some connectivity still exists.

If the Fibre Channel cable were faulty, there would likely be a complete loss of connection for that path, not just degraded performance, assuming the other HBA is functional.

While a reboot can help re-initialize hardware and drivers, Fibre Channel configuration changes often require specific updates to the switch zoning rather than just a server reboot.

When an HBA is replaced, it typically has a new World Wide Name (WWN). Fibre Channel switch zoning uses WWNs to control which HBAs can access which storage targets. If the zoning is not updated with the new HBA's WWN, it might not be able to fully access the storage paths, leading to reduced performance or connectivity issues.
