Question #46
Which three statements are considered best practice when configuring an NFS appliance port on Cisco UCS? (Choose three.)
  1. A
    If storage isconfigured in active/passive mode and both fabric interconnects require communication to the same controller, then the appliance port VLANs should be allowed on the upstream switch.
  2. B
    If storage and servers are located in the same subnets, then the appliance port VLANs should be allowed on the upstream switch.
  3. C
    Use of the same VLAN for multiple storage protocol traffic is highly recommended in converse VLAN namespace use.
  4. D
    If storage must be accessed outside of the Cisco UCS domain, then the applianceport VLANs should be allowed on the upstream switch.
  5. E
    Cisco UCS supports Static and Link Aggregation Control Protocol port channels for appliance port configuration. However, no virtual port-channel support.
  6. F
    Configuration of the VLAN tagging on the storage side and on the Cisco UCS side simultaneously is recommended.

Correct Answer:
ABD
Why Appliance Port VLANs Should be Allowed on Uplinks There are number of reasons why an upstream switch should allow storage appliance port traffic.
These include:
✑ If storage must be accessed outside of the UCS domain.
✑ If storage and servers are located in different subnets.
✑ If storage is configured in Active/Passive mode and both fabric interconnects require communication to the same controller.
