Your customer purchased a ProLiant server that will be connected to a Primera A650 array. They configured Word Wide Name (WWN) based zoning between the two devices on a Storage Area Network (SAN) fabric.

Your customer purchased a ProLiant server that will be connected to a Primera A650 array. They configured Word Wide Name (WWN) based zoning between the two devices on a Storage Area Network (SAN) fabric.
What advantage does this zoning type provide?
WWN-based zoning allows zoning definitions to be retained even when the device connected to the SAN fabric is moved to a different port or switch. This is because the zoning is based on the World Wide Name, a unique identifier for Fibre Channel devices, rather than their physical connection point. Therefore, the correct answer is that WWN-based zoning provides the advantage of retaining the zoning definition even when the device is moved to a different port or switch in the fabric.
Zones can be defined using the device WWN to uniquely identify zone members. The advantage is retaining the zoning definition even when the device is moved to a different port or switch in the fabric. The disadvantage is that the zoning definitions must be changed whenever an HBA is replaced with another, having a different WWN.
