Answer: D
Q13. Refer to the exhibit.
A customer is having a problem with NPV. Which of these is the cause of the problem?
A. No server was requested or received by the FLOGI database.
B. One external link must be up for server interface to be up.

Answer: B
Q14. Your customer is an ISP providing service to thousands of end customers. Its main concerns are focused on using up the total number of 4096 VLANs per VDC, wasting an unused block of IP addresses, and IP address management. Which technique will address these concerns?
A. create a separate VDC to scale VLAN limitation and upgrade to Cisco Nexus 7018 Switch
B. segment VLANs using secondary IP addresses, which will reduce the management domain
C. create mapping between the VLAN and VSAN to run FCoE to consolidate VLAN and IP addresses
D. use PVLANs, which will solve the scalability problem and provide IP address management
Answer: D
Q15. What is one requirement for running FabricPath on a Cisco Nexus 7000 Series switches?
A. You must have an F Series module
B. You must run NX-OS version 4.2 to run FabrciPath
C. ISSU needs to be disabled to run FabricPath
D. LAN_TRANSPORT_SERVICES_PKG license needs to be installed to run FabrciPath
Answer: A
Q16. Cisco UCS users residing behind N5K2 are complaining about poor performance with a single LAN application in the data center. Which statement best explains what is wrong with N5K2?
A. Traffic balancing is based on the destination IP address.
B. Port channel members do not have equal bandwidths.
C. The trunk between the Nexus 5000 switches is filtering all VLANs.
D. E2/1 on N7010-C2 is not configured as a trunk for application traffic from N5K2.
Answer: A
Explanation:
Traffic balancing is based on the destination IP address
Use the “show port-channel load-balance” command to verify.
Q17. Which statement is true regarding the port channel 100 and 101 configurations between the Nexus 7010 switches?
A. The vPC assignments on N7010-C2 are incorrectly swapped
B. N7010-C1 is not allowing any active VLAN traffic to pass on Po100 and Po101.
C. LACP is not configured to initiate negotiations.
D. The vPC peer-keepalive is down between the two Nexus 7000 switches.
Answer: A
Explanation:
The vPC assignments on N7010-C2 are incorrectly swapped.
The “show vpc” command will show you that the keepalives are active, and that there areactive VLANs. The “show port-channel summary” command shows that LACP is enabled.
Q18. Refer to exhibit.
Customer has a pair of Cisco Nexus7010s switches and connected to a single Cisco Nexus5548 switch via vPC. Customer has a combination of M1 and F1 I/O Modules in Cisco Nexus7010s.
Why is the design described not supported?
A. Mixing I/O Modules on the Same Side of a Peer Link is not supported
B. vPC does not support split control plane
C. You can not configure a vPC peer link to configure two devices as vPCs
D. Need to add another Cisco Nexus5548 switch to the topology to make this work.
Answer: A
Q19. In order to fulfill the requirement to prevent the creation of end-to-end loops across a multihomed OTV network that connects two different data centers, what is the solution to this problem?
A. prioritize the transmission of STP BPDUs across the overlay
B. design the DCI connectivity as a hub and spoke
C. define a conservative TTL for all packets traversing the OTV network
D. enable AED on a per-VLAN basis between each OTV edge device with the same site ID
Answer: D
Q20. There is an ARP storm in VDC 1. Some users on VDC 2 notice that ARP is not resolving for their gateway on the Cisco Nexus core. What is the cause?
A. The ARP CoPP class committed information rate is exceeded, resulting in ARP loss in all VDCs.
B. The administrator has not correctly configured the ARP CoPP class in VDC 2.
C. The ARP traffic in VDC 1 is copied to the host ports in VDC 2, causing overutilization and output discards.
D. Because the ARP process in the default VDC (VDC 1) is responsible for processing ARP traffic for all VDCs, VDC 2 will be affected.
Answer: A
