• Question 249:

  When designing data centers for multitenancy, which two benefits are provided by the implementation of VSAN and zoning? (choose two)

  A. VSAN provides a means of restricting visibility and connectivity among devices connected to a zone
  B. VSANs have their own set of services and address space, which prevents an issue in one VSAN from affecting others
  C. Zones provide the ability to create many logical SAN fabrics on a single Cisco MDS 9100 family switch
  D. VSANs and zones use separate fabrics
  E. Zones allow an administrator to control which initiators can see which targets
  B. VSANs have their own set of services and address space, which prevents an issue in one VSAN from affecting others
  E. Zones allow an administrator to control which initiators can see which targets

• Question 250:

  Which of these is true of IP addressing with regard to VPN termination?

  A. addressing designs need to allow for summarization
  B. termination devices need routable addresses inside the VPN
  C. IGP routing protocols will update their routing tables over an IPsec VPN
  D. designs should not include overlapping address spaces between sites, since NAT is not supported
  C. IGP routing protocols will update their routing tables over an IPsec VPN

  ---

  An IPsec VPN is an overlay on an existing IP Network. The VPN termination devices need routable IP addresses for the outside Internet connection. Private IP address can be used on the inside of the VPN. Just a good IP network design supports summarization, the VPN address space needs to be designed to allow for network summarization. NAT may be needed to support overlapping address space between sites in an organization.
