Which two statements about SAN zoning on Cisco Nexus switches are true? (Choose two.)
A. Unlike configured zones, default zone information is not distributed to the other switches in the fabric.
B. Traffic can either be permitted or denied among members of the default zone. This information is not distributed to all switches. It must be configured in each switch.
C. The settings for default zone configurations cannot be changed.
D. To activate a zone set, you must copy the running configuration to the startup configuration after the zone set is configured.
E. Soft zoning restrictions will not prevent a source device from accessing a device outside its zone, if the source knows the Fibre Channel ID of the destination.
F. Hard zoning is enforced by the hardware on each FLOGI sent by an N Port.
Correct Answer: BE
Explanation/Reference:
Explanation:
Each member of a fabric (in effect a device attached to an Nx port) can belong to any zone. If a member is not part of any active zone, it is considered to be part of the default zone. Therefore, if no zone set is active in the fabric, all devices are considered to be in the default zone. Even though a member can belong to multiple zones, a member that is part of the default zone cannot be part of any other zone. The switch determines whether a port is a member of the default zone when the attached port comes up. Unlike configured zones, default zone information is not distributed to the other switches in the fabric Traffic can either be permitted or denied among members of the default zone. This information is not distributed to all switches; it must be configured in each switch. http://www.cisco.com/c/en/us/ td/docs/switches/datacenter/mds9000/sw/5_2/configuration/guides/f abric/DCNM-SAN/fm_fabric/zone.html
