Q11. 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 


Q12. 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.


Q13. 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.

B. switch(config-if)# otv isis hello-interval 30 

C. switch(config-vlan)# otv isis hello-interval 30

Answer: C 


Q16. It has been determined that unknown unicast, multicast, and broadcasttraffic is not correctly being switched through either Nexus 7010 switch. Whichstatement best describes the cause of this issue? 

A. No VLANs are allowed across the vPC peer link. 

B. The MST STP is not enabled on either switch. 

C. The default VLAN is inactive. 

D. VTP is not configured to handle this type of traffic. 

Answer: B 

Explanation:

The MST STP is not enabled on either switch From both switches the “show spanning-tree mst” command show that the switch is not in MST mode.
