• Question 75:

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

  While troubleshooting HSRP adjacency, a packet analyzer captures the remote packet with the information: IP 224.0.0.102 with a MAC address of 0000.0C9F.0256. The DCI local group number is 256.

  Which solutionresolves the problem?

  A. Request that the remote data center change the HSRP version to V1.
  B. Report the issue as a suspected bug because the group number is correct based on the analyzer.
  C. Request that the remote data center verifies that they do not have an HSRP password configured.
  D. Request that the remote data center to use the correct HSRP group number.
  E. Change the local HSRP version to V1.
  D. Request that the remote data center to use the correct HSRP group number.
