Cisco CCIE Data Center Written Sample Questions:

1. Refer to the exhibit.

The Cisco UCS domain is operating in switching mode. A network administrator notices that no traffic is traversing the uplinks on Fabric Interconnect B (Path C).
Which actions might be used to change this behavior?

A) Modify the bridge priority on the fabric interconnects so that one of the Nexus 5548s will always be the root bridge.
B) Modify the port priorities on the fabric interconnect uplinks (Paths B and C) so that they are a higher priority than ports Eth1/4 and Eth1/9 (Path D).
C) Modify the bridge priority on the Nexus 5548s so that one of them will always be the root bridge.
D) Fix the port channel configuration between Fabric Interconnect B and Nexus 5548 B as the port channel IDs do not match.
E) This is an invalid configuration as Cisco UCS fabric interconnects cannot be directly connected.

2. Overlay Transport Virtualization (OTV) uses the Authoritative Edge Device (AED) to perform which tasks?

A) The AED is responsible for load balancing all traffic for all VLANs across the transport network.
B) The AED is responsible for sending all unicast traffic in a site, while either node in a site can transmit multicast and broadcast.
C) The AED is responsible for handling all unicast, broadcast, and multicast traffic for a given VLAN within a site.
D) The AED is responsible for MAC address dispute contention for a given VLAN.

3. Refer to the exhibit.

What action must be taken to make fc1/1 capable of being an ISL port channel member operating at 4 GB?

A) The B2B credit value of interface fc1/1 must be raised to a minimum of 100.
B) One of the interfaces between fc1/2 and fc1/6 must be placed in out-of-service mode to free up bandwidth in the port group so that fc1/1 can use that bandwidth.
C) Interface fc1/1 must be placed into dedicated rate mode.
D) No action is necessary because shared rate mode ports are fine for ISLs.
E) No action is possible because module 1 is oversubscribed and will only support ISLs if the ports operate at 2GBs.

4. Refer to the exhibit.

When a CNA host connects to the virtual interface of the switch, what will happen?

A) The switch will not initialize because it is in the wrong mode.
B) The host will not connect. The vFC port number does not match the Ethernet interface.
C) The host will negotiate using DCBX and connect properly.
D) The host will negotiate using DCBX and will change parameters as required, but a shut/no shut is needed on the interface.

5. Nexus# 57ther igmp snooping vlan 120 IGMP Snooping information for vlan 120 IGMP snooping disabled Optimised Multicast Flood (OMF) disabled IGMP querier none Switch-querier enabled, address 1.1.1.1, currently not running IGMPv3 Explicit tracking enabled IGMPv2 Fast leave disabled IGMPv1/v2 Report suppression enabled IGMPv3 Report suppression disabled Link Local Groups suppression enabled Router port detection using PIM Hellos, IGMP Queries Number of router-ports: 0 Number of groups: 0 Active ports: Po100 Po111
Which statement best describes what is depicted in the show command output?

A) IGMP snooping has been disabled for VLAN 120 in VLAN configuration mode.
B) IGMP snooping is not active for VLAN 120 because the IGMP feature has not been enabled on the switch with the feature igmp command.
C) IGMP snooping is not active for VLAN 120 because VLAN 120 does not exist in the VLAN database.
D) IGMP snooping has been disabled on the VLAN 120 SVI.
E) The IGMP snooping querier for VLAN 120 is not in a running state because the Loopback interface configured with 1.1.1.1/32 is currently in a down state.
