• Question 128:

  What is a true statement concerning automatic Fibre Channel pinning on a Cisco Unified Computing System 62XX Fabric Interconnect?

  A. By default, uplink Fibre Channel interfaces are configured for VSAN trunking.
  B. Using NPV, each downstream server will be pinned to an uplink port that is based on a PIN group.
  C. The Fibre Channel pinning process is implemented differently than end-host MAC address pinning.
  D. With VSAN trunking, the automatic pinning of server traffic to Fibre Channel uplink ports will be based on the server WWN.

• Question 129:

  Which two are true with respect to the unified ports on the Cisco Unified Computing System 62XX Fabric Interconnect? (Choose two.)

  A. The port mode is automatically discovered after plugging in a LAN or Fibre Channel- attached cable.
  B. By default, unified ports that are changed to Ethernet port mode are set to uplink Ethernet port type.
  C. Ethernet ports must be grouped together in a block and must start with the first port and end with an odd numbered port.
  D. Alternating Ethernet and Fibre Channel ports is supported on the expansion module.
  E. After making port mode changes on an expansion module, the module will reboot.
  F. In a standalone configuration, making port mode changes to the fixed module will not cause the fabric interconnect to reboot.

• Question 130:

  Which of the following is true with respect to recovery from failure with automatic pinning that is configured on a cluster of Cisco Unified Computing System 62XX Fabric Interconnects?

  A. By default, server MAC addresses are pinned to uplink interfaces using PIN groups.
  B. When a northbound fabric interconnect link goes down, the affected servers will use NIC teaming to re-establish connectivity on the second fabric interconnect.
  C. When a northbound fabric interconnect link goes down, the fabric interconnect will send a gratuitous ARP to the northbound switch to announce the servers on the new port.
  D. In the event that all uplink ports on the fabric interconnect lose connectivity, the 22XX I/O module shuts down all of the host ports until at least one uplink is restored.
  C. When a northbound fabric interconnect link goes down, the fabric interconnect will send a gratuitous ARP to the northbound switch to announce the servers on the new port.
