06.21 What might be the problem if a DHCP client suddenly finds itself in a different IP subnet from the one it should be in? |
The most likely problem is that a rogue DHCP server has been introduced into the network and is handing this device an incorrect lease. |

FTP uses both TCP ports 20 and 21 for the data channel and the control channel, respectively. |

|
|
06.25 What could cause a server that you can ping not to provide the particular TCP/IP service, such as FTP, HTTP, and so on, that you expect it to offer? |
Quite simply, the service might not be running currently on that server. Another possibility might be that a firewall between the client and the server has blocked the protocol in question from passing. |
|
|
06.26 What might cause your email to stop functioning properly when you change Internet service providers? |

TFTP servers respond to UDP messages sent to port 69. |
|

10.18 What EIGRP information is held in RAM and maintained through the usage of hello and update packets? (Select all that apply.) A. DUAL table B. Neighbor table C. Topology table D. Successor route |
What EIGRP information is held in RAM and maintained through the usage of hello and update packets? (Select all that apply.) A. DUAL table B. Neighbor table C. Topology table (EIGRP holds 3 tables in memory: Routing, Topology and Neighbor. Routing is share, but each router builds their Neighbor and Topology tables using hello packets.) D. Successor route (This is “sort of” -- the successor route is stored in the Routing Table. But it is not listed as correct in the book.) |

10.19 Which is true regarding EIGRP successor routes? A. Successor routes are saved in the neighbor table. B. Successor routes are stored in the DUAL table. C. Successor routes are used only if the primary route fails. D. A successor route is used by EIGRP to forward traffic to a destination. |

Successor routes are used only if the primary route fails. D. A successor route is used by EIGRP to forward traffic to a destination. (Successor routes are preferred routes in EIGRP. Think "successful." They are stored in the routing table.) |
