    I got the last question wrong. I put 192.168.1.16 – I’m so used to subnet zero being in play.

  2. Hi RW – take another look – subnet zero is in play!

  3. RW says:

    I got it now, thanks:

    2*2*2 = 8, not 6.

    I got 1/6 not bad for a CCIE.

    :)

  5. To Rack009:

    First of all, your screen name is frickin hilarious! Thanks for that.

    Secondly, your post is equally funny!

    I recently took the CCENT exam and scored a 970 out of 1000. I simply refused to do subnetting without my calculator. I guess I am lazy after all. :-)

    Hi Guys,

    I am big fan of you and you IE workbooks and COD for routing and switching labs. Can you please help me with following query:

    Why we cannot ping our own serial interface ip address until we put ip address on other serial interface to which we are connected to through back to back dce/dte cable. I know serial interfaces don’t have mac addresses, maybe some sort of layer 3 to layer 2 resolution issue which comes. Also when we ping our own serial interface ip address the response time is double as compare to ping the other connected serial interface ip address so that means request first go to other interface and then comes back, why does it happen so. My question might look stupid and I am really interested to know this stuff.

    Kindly help me understanding this

    Thanks!
    Deepak Arora

    The last question has the wrong answer given as the solution for this quiz. It should not 192.168.1.22, it should :

    Network: 192.168.1.0/29 11000000.10101000.00000001.00000 000
    HostMin: 192.168.1.1 11000000.10101000.00000001.00000 001
    HostMax: 192.168.1.6 11000000.10101000.00000001.00000 110
    Broadcast: 192.168.1.7 11000000.10101000.00000001.00000 111

  8. Hi Nael!

    Please note it is asking for the last usable host address on the THIRD subnet. Please look again – our answer of 192.168.1.22 is correct.

  9. Keith says:

    what does it mean by the host address on the thirdsubnet please email me at kmharvey08@hotmail.com.

    sub Mask 255.255.255.248
    Ip ad 192.168. 1 .0
    Sub ID 192.168. 1 .8
    first 192.168. 1 .9
    last 192.168. 1 .14
    Broadcast 192.168. 1 .15

    Im preparing to take my CCENT next week. What are some things that helped you out. And I didn’t know you could use a calculator in the testing room!

  12. Lakshan Bandara says:

    @Keith,
    subnet mast 255.255.255.248 means:
    192.168.1.0/29 = In last octet, 3 host bits.

    Subnets of 192.168.1.
    (1) 00000|001 – 00000|110 = 1 – 6
    (2) 00001|001 – 00001|110 = 9 – 14
    (3) 00010|001 – 00010|110 = 17- 22

    Therefore, last usable host address on the THIRD subnet is:
    192.168.1.22 /29

    ~ Sincerely, Lakshan Bandara

    the 4th question asking what subnet id is 192.168.1.67/28 has to be incorrect because i am punching in the correct answer and its saying its wrong

    28 bits is subnetmask 255.255.255.240 giving you increments of 16 ip addresses

    the id is on the first one of that increment making it 192.168.1.64/28

    so the answer is supposed to be 192.168.1.64/28 which is what i punched in and it said it was wrong. i went back and tried it without the cidr notation just 192.168.164 and it said correct. this is incorrect the question asked for subnet id. subnet id’s on ccna’s test usually require the cidr notation to stay in the answer.
