Q1. When configuring LLDP on Cisco Nexus 5548 Switch, what is the purpose of LLDP hold time global configuration command?
A. LLDP holdtime option is to set the length of time in milliseconds that a device should save LLDP information received before discarding it
B. LLDP holdtime option is to set the length of time in seconds that a device should save LLDP information received before discarding it
C. LLDP holdtime option to is the length of time in milliseconds to wait before performing LLDP initialization on any interface
D. LLDP holdtime option to is the length of time in seconds to wait before performing LLDP initialization on any interface
Answer: B
Q2. Which statement is true regarding STP?
A. When the spanning-tree topology is calculated based on default parameters, the path between the source and destination end stations in a switched network might not be ideal.
B. The path between the source and the destination end stations is always ideal with the default spanning-tree parameter.
C. The path between the source and the destination end stations is determined by the speed of the link; the slowest link speed will become the root port during the election.
D. The path between the source and the destination end stations is determined by the lowest MAC address; the lowest MAC address will become the root port during the election.
Answer: A
Q3. Refer to the exhibit.
VSAN traffic is not being routed through SAN fabric. Which action is helpful to resolve the problem?
A. Make sure that the FSPF hello interval value matches on both switches.
B. Change the FSPF hello timer back to the default of 5 seconds.
C. Make sure that the FSPF hello timers are different so that they do not compete.
D. Make sure that the FSPF dead timers are both set to 0.
Answer: A
Q4. You have enabled configuration synchronization between two Cisco Nexus 5548UP Switches. You create a port channel on switch 1 and determine that it was not synchronized with its peer. The peer switch can be pinged on the management VRF. When you check your peer status, you receive a "peer not reachable" message in the command output. What is the explanation for this?
A. CDP is disabled.
B. An LACP mismatch exists on the peer interfaces.
C. UDLD is disabled.
D. CFSoIP is disabled.
E. Multicast routing is enabled.
Answer: D
Q5. If no traffic was ever sent across the overlay, what will the show mac address-table command on the OTV VDC indicate?
A. invalid command
B. the MAC address of the local OTV join interface
C. the system IDs of all the local OTV edge devices
D. the system IDs of all the local and remote edge devices in the overlay
E. all the MAC addresses learned on the extended VLAN
Answer: B
Q6. While the Nexus 7010 switches are configured with vPC, the Nexus 5000 switch connections to each Nexus 7010 are configured as regular port-channels. Which statement best describes the problem affecting the port channel on N5K1?
A. LACP is not configured to initiate negotiations.
B. N5K1 must also be configured with vPC.
C. load-balancing is not configured correctly on N5K1.
D. The remote ends of the port-channel on N5K1 cannot use the same interface
Answer: D
Explanation:
The remote ends of the port-channel on N5K1 cannot use the same interface.
If you look at the remote ends and issue the “show interface port-channel, you will see thatonly one physical interface is assigned to the port channel.
Q7. A customer is deploying FCoE in its networ and has found that the connected host does not support FIP. Which command will be useful in troubleshooting this issue?
A. show platform fcoe_mgr info interface vfc id
B. show platform fcoe_mgr info software interface vfc id
C. show platform software fcoe_mgr info interface vfc id
D. show platform software interface fcoe_mgr info vfc id
Answer: C
Q8. Which statement would explain why the overlay interface on an OTV edge device is not in the up state?
A. The site identifiers are identical within a multihomed site.
B. Multicast groups are not mapped to a range of SSM addresses to carry the multicast traffic.
C. An adjacency server is not configured for connectivity over a multicast transport.
D. The OTV IS-IS metrics do not match across all adjacent OTV edge devices.
Answer: B
Q9. A customer calls you to report that it receives an error when entering the pinning max-links 4 command in FEX configuration mode on its Cisco Nexus 5596T Switch. Which of these is a likely cause for this condition?
A. The FEX fabric interface is down.
B. The transceiver is incorrect.
C. A fabric interface is in a port channel.
D. The fabric interface switchport mode is set to Access.
E. Only two fabric interfaces are connected.
Answer: C
Q10. Refer to the exhibit.
The server port connected to the NPV edge switch does not come online. Which action should fix the problem?
A. Move the NP ports on the NPV edge and the F ports on the NPIV into the same VSAN
99.
B. Move the NP ports on the NPV edge and the F ports on the NPIV in the default VSAN 1.
C. Move all the ports into VLAN 1.
D. Move all the ports into VSAN 99.
E. Move all the ports into VLAN 99.
Answer: A
Q11. Which three commands will show all the MAC addresses learned from remote sites in an OTV overlay? (Choose three.)

B. show otv route overlay
C. show otv vlan
D. show ip arp
E. show mac address-table
F. show otv site
Answer: ABE
Q12. FCoE traffic from C200-1 on VSAN 13 is not being switched through the network. Which statement explains the cause of the problem?
A. The LAN switchport on N5K2 must be configured as a trunk.
B. VLAN 1013 on N5K2 is not allowed on the LAN.
C. The vFC on N5K2 that is associated with VSAN 13 is in the wrong port mode.
D. The M1 card on the Nexus 7000 switch does not support FCoE.
Answer: D
