A. B. C. D. E. F.


In a Fibre Channel storage area network (SAN), a zone is a logical grouping of one or more devices. Zoning enables a SAN administrator to limit access to specific devices by defining which devices can communicate with each other. When a device is added to a zone, it can communicate with other members of the zone but is isolated from devices that are not part of the zone.

To add a device as a member to a zone, the following three options can be used:

  1. Fibre Channel ID: Each Fibre Channel device has a unique identifier assigned to it, which is called the World Wide Node Name (WWNN) and the World Wide Port Name (WWPN). A WWNN is assigned to the device's adapter, while a WWPN is assigned to each port on the adapter. A WWPN is often used to add a device to a zone.

  2. Device Alias: A device alias is a user-defined name that is associated with a Fibre Channel device. A device alias can be used in place of a WWPN to add a device to a zone, making it easier to manage and maintain.

  3. Fully Qualified Domain Name (FQDN): A fully qualified domain name is a complete domain name that specifies a device's exact location in the DNS hierarchy. An FQDN can be used to add a device to a zone, but it is less commonly used than WWPN or device alias.

Therefore, the correct answers are B. Fibre Channel ID, E. device alias, and A. fully qualified domain name. The other options, VLAN ID, IP address, and LUN ID, are not used to add a device to a zone in a Fibre Channel SAN.
