6An administrator is replacing a fabric interconnect. The failed fabric interconnect was FI-A and was master at the time of failure. Which process brings the replacement fabric interconnect into the cluster?
- Connect the new FI-A to the management network and the Layer 1/Layer 2 links to the existing FI-B. Use the Full State Backup file to restore the configuration when prompted at the console.
- Connect the new FI-A to the management network and the Layer 1/Layer 2 links to the existing FI-B. Let the system sync with FI-B when prompted at the console.
- Connect the FI-A to the management network and the Layer 1/Layer 2 links to the existing FI-B. Use the All Configuration backup file to restore the configuration through Cisco UCS Manager GUI.
- Connect the new FI-A to the management network only. Use the Full State Backup file to restore the configuration through Cisco UCS Manager GUI. Connect the Layer 1/Layer 2 cables.
- Connect the new FI-A to FI-B using the Layer1/Layer 2 cables only. Sync the configuration when prompted. Connect the management interface when the configuration is synced.

9Which two statements about multicast routing are true? (Choose two.)
- Multicast routes are used to directly forward traffic without making RPF checks.
- IPv6 static multicast routes are supported.
- You can define RPF routes for multicast when you want multicast data to diverge from the unicast traffic path.
- You can define RPF routes for multicast on border routers to enable reverse path forwarding to an external network.
- RPF routes for multicast can be redistributed.
Answer: C, D
10Refer to the exhibit. Which three steps must be taken to add NFS storage to the Cisco UCS domain? (Choose three.)
- Configure fabric interconnect A and B to Ethernet switching mode.
- Create a LAN cloud VLAN on fabric A and fabric B.
- Configure Eth1/17 as an appliance port.
- Configure a QoS policy for NFS storage.
- Create an appliance VLAN on fabric A and fabric B.
- Configure Eth1/17 as a unified storage port. ABC
