Q24. 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
Q25. 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. 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
Q28. Refer to the exhibit.

B. The bound interface should be in an STP learning state for both the native VLAN and the member FCoE VLAN that is mapped to the active VSAN.
C. The bound interface should be in an STP forwarding state for both the native VLAN and the member FCoE VLAN that is mapped to the active VSAN.
D. The bound interface should be in an STP blocking state for both the native VLAN and the member FCoE VLAN that is mapped to the active VSAN.
