    Switch1(config-line)# login
  • D: Switch1(config)# interface fa0/1 
    Switch1(config-if)# ip address
  • E: Switch1(config)# interface fa0/1

  • B: OSPFv3 was developed to support IPv6 routing.
  • C: Loopback addresses are used to form routing adjacencies.
  • D: EIGRP, OSPF, and BGP are the only routing protocols that support IPv6.
  • E: Link-local addresses are used to form routing adjacencies.

Question 7

  • A: A conflict of IP addresses happens, because other public routers can use the same range.
  • B: Addresses in a private range will not be routed on the Internet backbone.
  • C: Only the ISP router will have the capability to access the public network.
  • D: The NAT process will be used to translate this address to a valid IP address.
