A customer wants the flexibility to attach any host to any switch port without affecting the zoning
configurations. Which zoning method(s) should be recommended?

A.
Mixed zoning

B.
Port zoning

C.
Both WWN and port zoning

D.
WWN zoning

Explanation:
Types of Zoning

Zoning can be categorized into three types:
• Port zoning: Uses the physical address of switch ports to define zones. In port zoning, access to
node is determined by the physical switch port to which a node is connected. The zone members
are the port identifier (switch domain ID and port number) to which HBA and its targets (storage
devices) are connected. If a node is moved to another switch port in the fabric, port zoning must
be modified to allow the node, in its new port, to participate in its original zone. However, if an HBA
or storage device port fails, an administrator just has to replace the failed device without changing
the zoning configuration.
• WWN zoning: Uses World Wide Names to define zones. The zone members are the unique
WWN addresses of the HBA and its targets (storage devices). A major advantage of WWN zoning
is its flexibility. WWN zoning allows nodes to be moved to another switch port in the fabric and
maintain connectivity to its zone partners without having to modify the zone configuration. This is
possible because the WWN is static to the node port.
• Mixed zoning: Combines the qualities of both WWN zoning and port zoning. Using mixed zoning
enables a specific node port to be tied to the WWN of another node.
