NO.1 A customer is troubleshooting FCoE in its network. They have discovered that vFC is currently

down and there is no active STP port state on the bound Ethernet interface. What should the STP

port state be to correct this issue?

A. The bound interface should be in an STP forwarding state for both the native VLANand the

member FCoE VLAN that is mapped to the active VSAN.

B. The bound interface should be in an STP blocking state for both the native VLANand the

member FCoE VLAN that is mapped to the active VSAN.

C. The bound interface should be in an STP learning state for both the native VLANand the

member FCoE VLAN that is mapped to the active VSAN.

D. The bound interface should be in an STP forwarding state for the native VLAN only.

Answer: A

 

NO.2 There is an ARP storm in VDC 1. Some users on VDC 2 notice that ARP is not resolving for their

gateways on the Cisco Nexus core. What is the cause?

A. The ARP traffic in VDC 1 is copied to the host ports in VDC 2,causing overutilization and output

discards.

B. Because the ARP process in the default VDC (VDC 1) is responsible for processing ARPtraffic

for all VDCs, VDC 2 will be affected.

C. The administrator has not correctly configured the ARP CoPP class in VDC 2.

D. The ARP CoPP class committed information rate is exceeded, resulting in ARP lossin all VDCs.

Answer: D

 

NO.3 You customer is an ISP providing service to thousands of end customers. Its main concern 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 mapping between the VLAN and VSAN to run FCoE to consolidate VLAN and IP

address

B. segment VLANs using secondary IP addresses, which will reduce the management domain

C. create a separate VDC to scale VLAN limitation and upgrade to Cisco Nexus 7018 Switch

D. use PVLANs,which will solve the scalability problem and provide IP address management

Answer: D

 

NO.4 A customer is deploying multihop FCoE in its network. Which guideline must the customer

B. Using an AED eliminates the need for FHRP .

C. VRRP is recommended over HSRP or GLBP .

D. FHRP should be limited to only the internal OTV interfaces.

Answer: A
