Does anyone know of there are any decimal-binary, binary-decimal, hex-dec, dec-hex and hex-binary conversion questions in the icnd 1 exam. Just want to know because don`t know if i should spend a lot a time on this section.. Please advise ...

    You should be able to convert /27, /28, /29, etc. into subnet masks and wildcard masks and vice-versa. You should be able to figure out how many subnets and how many hosts per subnet a particular mask allows. For many people, those tasks involve converting to/from binary, but if you can manage without, all the more power to you. :)

    Understanding hex will help you with IPv6 (ICND2), understanding some debug commands, and identifying the ranges that certain values can be set to. I don't believe hex conversion is specifically mentioned in the exam syllabus.

    ICND1 won't have you do VLSM. That's saved for ICND2 icon_smile.gif

    Otherwise - You'll be expected to do these around this amount of time. Crazy? Nah, you'll get used to it. To get used to it - you need to practice. A lot.

    I recommend practicing every day, take a break, and jump right in again. Do about 10 range finding questions every other day, taking a break between - to help with your retention. The faster and more accurate your subnetting means you'll have more time for other things and other possible problems. You'll be asked questions that need you to subnet to troubleshoot, design, or count.

    Do the practices without a calculator. To check, use a calculator. It won't matter how fast you are if you do it wrong.

    Speed:
    These are the time limits that you should be able to exceed by the time you go for your test. How do you get better? Perfect Practice makes perfect.
    5 Seconds - Convert Dotted Decimal to Prefix/CIDR notation.[255.255.128.0 to /17]
    5 Seconds - Convert Prefix/CIDR notation to Dotted Decimal.[/17 to 255.255.128.0]
    15 Seconds - Find: Subnet, Broadcast, Range. [10.0.128.0, 10.0.255.255, 10.0.128.0 - 10.0.255.255]
    15 Seconds - Find: Number of subnets, Hosts per subnet. [512, 32768]
    30 Seconds - Find mask that meet requirements that maximize subnets / hosts per subnet.

    Practice Sites.

    Network, Broadcast and First,Last Usables = IP Subnet Practice
    CIDR Mask to Dotted Decimal = CIDR to Dotted Decimal
    Dotted Decimal to CIDR Mask = Dotted Decimal to CIDR


    Over prepare yourself. It's not that difficult to master, just takes time and flexing those mind muscles.

    Like my old AF SSgt does - he prepared us for the rifle assembly test by making us shoot for a goal of a minute. The real time, unknown to everyone else, was 2 minutes. The assembly test didn't phase us while other groups slacked behind. Kind of the same idea here. Push for more than the target number.
    In order to succeed, your desire for success should be greater than your fear of failure.
