• Question 62:

  Which three statements are considered best practice when configuring an NFS appliance port on Cisco UCS? (Choose three.)

  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.
  B. If storage and servers are located in the same subnets, then the appliance port VLANs should be allowed on the upstream switch.
  C. Use of the same VLAN for multiple storage protocol traffic is highly recommended in converse VLAN namespace use.
  D. If storage must be accessed outside of the Cisco UCS domain, then the applianceport VLANs should be allowed on the upstream switch.
  E. Cisco UCS supports Static and Link Aggregation Control Protocol port channels for appliance port configuration. However, no virtual port-channel support.
  F. Configuration of the VLAN tagging on the storage side and on the Cisco UCS side simultaneously is recommended.
  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.
  B. If storage and servers are located in the same subnets, then the appliance port VLANs should be allowed on the upstream switch.
  D. If storage must be accessed outside of the Cisco UCS domain, then the applianceport VLANs should be allowed on the upstream switch.

  Which two statements about IP-directed broadcast are true? (Choose two.)

  A. The destination address in the IP header of the packet is rewritten to the configured IP broadcast address for the subnet, and the packet is sent as a link-layer broadcast.
  B. An IP-directed broadcast is an IP packet whose destination address is a valid broadcast address, and it originates from a node that is also part of the same subnet.
  C. A switch that is not directly connectedto its destination subnet forwards an IP-directed broadcast in the same way it forwards unicast IP packets destined to a host on that subnet.
  D. All switches in the network forward an IP-directed broadcast in the same way they forward multicast IP packets.
  A. The destination address in the IP header of the packet is rewritten to the configured IP broadcast address for the subnet, and the packet is sent as a link-layer broadcast.
  C. A switch that is not directly connectedto its destination subnet forwards an IP-directed broadcast in the same way it forwards unicast IP packets destined to a host on that subnet.
