• Broadcast messages of which other protocols are also forwarded when a router is configured as a DHCP Relay agent?

  1. TFTP
     
  2. DNS
  3. Internet Time Service (ITS)
  4. NetBIOS name server
  5. NetBIOS datagram server
  6. BootP
  7. TACACS

• What are three DHCP troubleshooting commands?

  1. Show ip DHCP conflict
  1. Shows duplicate Ip addresses
  2. Show ip dhcp server events
  3. debug ip dhcp server packet
  1. Shows DHCP messages/communication

• 1.3 IPv6 Addressing

• How are IPv6 EUI-64 created?

  • Uses client MAC address
    
  • Adds FFFE in the middle
  • The seventh bit from the left is flipped

  
  This creates the interface ID

• 1.4 IPv6 SLAAC, Stateful DHCPv6 and Stateless DHCPv6

• What are the three IPv6 dynamic addressing options?

  1. SLAAC (StateLess Address Auto Configuration)
  2. Stateful DHCPv6
  3. Stateless DHCPv6

• What is important about SLAAC and prefix length?

  SLAAC only works when the prefix length is /64

• 1.5 Packet-forwarding process

  The Control Plane

• Where do the CEF FIB and CEF Adjacency table reside in?

  The Data Plane

• 2 EIGRP

• EIGRP uses Multicast when possible and Unicast when necessary over it's own IP protocol number.What is the IP protocol number and the Multicast addresses?

  IP protocol 88
  IP Multicast address: 224.0.0.10
  Multicast MAC address: 01:00:5E:00:00:0A

• What 4 parameters must match between EIGRP neighbors?

  1. Metric formula K values
  2. Primary subnet
  3. AS Number
  4. Authentication Parameters

• 2.2 EIGRP Configuration Modes

• What are the major differences between EIGRP Classic Configuration Mode and Named Mode?

  In Classic Configuration Mode most configuration is done under the EIGRP process and some is done on interface configuration level.
  
  In Named mode an EIGRP process is configured, then an EIGRP Instance is configured. Under the instance the settings are configured either directly like the Network command or under the Interface and Topology submodes.
