Sybex CCNA 7th Edition Dynamic Update #2

Hello, and welcome to my Second video dynamic update of my new Sybex CCNA 7th Edition Study guide. I hope you like it, find it informative, and will provide feedback to help me create better updates in the future.

This dynamic update will focus on configuring extended numbered access-lists based on a business requirement. Using three different examples, I’ll discuss the requirements and then show the configuration of the test statements on a router.

I’ll try and create these updates as often as possible, so study hard, and provide as much feedback as possible.

Until then — CCNA Ahead my friends!
Todd Lammle

    that’s a real treat for the learners.… thanks a lot Todd..

    but i’ve to ask a question here/

    should we have to write “permit ip any any” or “Permit ip any host{HOST-address}”.

    because i heard from many people that they’ve written permit ip any any and got the 100% in LAB.. please clear me as am going to give exam this 28th…


    • Thank you for writing.

      Well, my answer of “permit ip any “dest_host_address” is more in lines with the business requirements, but if others are telling you they got 100% on the ACL section with “permit ip any any”, then that is a better answer.
      The Cisco® answer is always the correct answer!

  5. Something very similar came in my test yesterday, and I got it right, thanks to Todd.

    I hope to see a video update about fixing issues of EIGRP in a real business environment.

    Thanks again.

    Hi Lamle,
    I have the 6th edition of your CCNA Study Guide and I found a non coherent text when you talk about UDP. It is written (page 78) “So if you’re using Voice over IP (VoIP), for example, you really don’t want to use UDP…”. The text explains that in case of VoIP TCP should be the correct protocol to use instead of UDP.
    But that’s not correct. Actually VoIP does use UDP and not TCP.

    what’s the difference between sybex edition 6th and edition 7th of ccna (640–802)?

  12. Hello Mr.Lammle,
    I am preparing for CCNA and I have some basic questions.I have gone through a number of forums but couldn’t find a clear cut answer and I thought it’s high time that I contact you.My questions are:

    1.Do switches have MAC address? If ‘yes’,do all ports have the same MAC address or each port has a different one?

    2.Do all LAN ports on a router have same MAC address or each has a different one?

  13. jfrouman

    Switches do have MAC addresses but in normal layer 2 operation they are not used for receiving and forwarding data frames.

    They are used when you want to access the switch remotely to manage or configure it such as via Telnet.

    A L2 switch generally only has an IP address for remote management purposes and it is assigned to a virtual interface (such as vlan 1).

    Example; PC1 — ping, PC1 does not currently have an entry in the arp table for this ip address so it sends a broadcast arp request, asking “who has ip address what is your mac address”

    2. SWitch1 sees this arp request, the first thing it does is make an entry in it’s mac-address table for PC1’s ip to mac translation and marks it reachable via fa0/1. Now SWitch2 forwards the arp broadcast out every other available port, except the port on which it was recieved (this action is know as flooding)

    3. PC2 sees the arp broadcast and replies with an arp unicast response to PC1 containing PC2’s ip address and mac-address.

    4. SWitch2 sees this arp response so it makes an entry in it’s mac-address table for PC2’s ip to mac translation, and marks it reachable via fa0/2.

    5.. PC1 eventually get the arp response from PC2 and packages the initial ping request with the correct mac-address for PC2.

    So basically switches forward mac address information of PC’s but don’t have a mac address the only mac address you will find is the addresses of the pc’s on the routing table.

  19. nyancey1

    I am starting to learn some Cisco® networking from the CCNA 640–802 study guide,Sixth Edition. Tell me, do I need to get the Seventh Edition of this study guide also? It’s all the same information.

  20. this book is very usefull for me thanks sir

  21. hutch1putt

    I am finding all of your material very helpful. I am studying NAT and have a problem with pages 666 (spooky)- 668 of CCNA Study Guide 7th Edition. I am going to take the ICND2 exam 8/14/13 so I may just be confused.

    On page 666 Figure 13.5…shouldn’t the netmask for the ip nat pool statement be

    And on page 667 Figure 13.6…shouldn’t the block size for the /30 network (s0/1 on Corp Router) to the ISP have a block size of 4…making the netmask on page 668

    Are these typos or am I missing something…???

  22. hutch1putt

    OK…I think I figured out my mistake on the Figure 13.6 problem…the block size of 8 is set by the fact there are 7 inside global addresses…not that it is a /30 network.

    But, I still believe the netmask of page 666 should be 192…and I think you may correct it on page 667…first paragraph…

  23. tamburro1966

    Hay todd how different is 640–802 from 640–803 is it harder in terms of talking the test,

    • I saw it’s 30–40% harder, yes.
      my new book, which just started shipping from amazon last week is very large!

  24. tamburro1966

    I ordered your new book also will it come with labs that i can use on packet tracer to study.


  25. Hi Todd — Thanks for your book, I passed my CCNA — R&S a week back. I am looking to take up CCIE — R&S. I am looking for e-books / other resources for CCIE. My work schedule does not allow me to take regular classes. Requesting your guidance please.

  26. tamburro1966
