    Scheduled to take Net+ this Saturday, after passing on "Boson" and "Transcender."

    I had spare cash and decided to get both practices.

    Do I have a good chance of passing? I am so nervous.....

    As for the folks who have passed it already, please give share me your blessings....haha..

    If your passing plenty of mock tests, and those areas that your not sure on that you have spent some time focusing on then you should be fine.

    Let us know the outcome.

    I only took the Boson tests before mine. Was good experience and close to the normal feel of the exam. If you're passing that you should be good but as always, make sure to double check on any area you feel slightly weaker in.

    Good luck :)

    Never used those practise ones so can't really comment...
    If there's anything you feel weak on or wanna discuss, then ask away! Now - i.e. before the test - would be a great time to bring it up!


    Otherwise - Best of Luck!

    Could you verify how I distinguish the tools?

    (1) Snips: Stripping or cutting cables for RJ-45.
    (2) Punchdown: Put the cable into RJ-45 plastic thingy.
    (3) Toner: Check where cable starts and ends.
    (4) TDR: See what is wrong with the cable.
    (5) Multimeter; Get electric properties of the cable.
    (6) Certifier: Check the cable throughput.

    anything else?
    Thanks.

    Hi,

    Snips - there are a couple of types I've seen. Some that look like scissors/wire-cutters with holes in. Use these to cut wire, and strip off insulator.

    Crimps (I'm including this because I've heard people call them 'punchdowns') - usually kind of shaped like a capital A, with long legs and a smaller triangle bit. Used to connect cable to the RJ45/RJ11 plugs/heads. Basically, you put the 8 coloured wires into the plug/head in the right sequence. You then shove the lot into the crimp and squeeze together the 'legs' and it presses the metal contacts into the wire, connecting the head to the cable. Fairly good tutorial here

    Punchdown tool - kind of 'probe' shaped. Used to connect UTP cable to to fixing at the back of a 'patch panel'.

    Tone Generator and Probe - basically, the tone generator usually looks like a box, often with a dial or buttons on, with either wires or a port or some way of connecting to a cable. That generates a tone all down the cable. The Probe can 'listen' for the tone, and thus help you identify the wire.

    TDR (Time Domain Reflectometer) - think sonar. You know how bats and dolphins can emmit a pulse of sound, and by listening for the echo, can 'see' how far away a wall is? It's analagous. This device sends a pulse down the cable, and based on the time the reflection takes to come back, can 'see' how far away the break in the cable is.
    OTDR (Optical TDR) - same thing but for fibre.

    Multimeter - the electronic Swiss Army Knife. Useful for about a million and one things and everyone should have one. Usually a rectangular, flattish thing with a big dial on it, these can measure voltage, resistance, and current. The voltage setting is great for testing power supplies or if power sockets are on (just make sure the dial is in the right place - if you try to measure 240V AC on the 2.5V DC setting something unpleasant might happen). The resistance setting is fantastic for checking wires - basically, a connected, good copper wire should have near zero resistance (current can pass easily); a broken wire will have effectively infinite resistance (current cannot pass). So if you touch a probe to pin 1 at one end of the cable, and the other proble to pin 1 of the other end of the cable, and get a 0 resistance, the cable's fine. But if you get a 99999 resistance, the cable is either broken or may be wired up wrongly.

    Certifier - never had one of these - they cost a LOT. Like hundreds or thousands. Basically, they run a series of checks on the cable, including crosstalk between pairs and various other stuff you simply can't do with a multimeter or cable tester. It the cable passes, they can be used to print off an official result, certifying that cable as meeting standards.
    A cable tester is a dumb, cheaper version of this that just check that the cable is wired up correctly to the plugs (i.e. that you haven't accidentally crossed the wires between pairs)

    also, what are good ways to memorize the colors of 568A or 568B cables?

    I have trouble memorizing, "which color is the wire on PIN 8?"

    You got me.
    I haven't had to make many, and when I have the colour hasn't mattered too much. When I need it I look it up.

    Perhaps someone else knows a trick?

    Oh, and I lied. Only passed Boson's exam simulation and not Transcender's.

    I am keep getting 86~88% on Transcender and give up on passing it.
    Does Transcender give credit only above 90%?

    Is the actual exam's passing cut like that?
    What's the approximated % of questions I need to get right on the actual one?

    Thanks.

    As far as I can tell, the way CompTIA mark is kept deliberately obscure. I'm not sure if all questions have equal value, and (it's been a while since I actually bothered to read through all the exam T&Cs but) I vaguely recall that they can add trial questions that don't even count to the final score.

    The score range is 100-900 (so ALL wrong = 100, all right = 900). The pass-mark is 720. So if you do a bit of maths with this, this translates to 77.5% pass rate. There are about 100 questions (the site says, "Maximum of 100 questions"). So as long as you're getting four right for every one you're less sure about, you should be okay.

    Passed (barely) !! Thanks ya'll. And yes, simulations are poorly implemented.

    Again, congrats. Good work and well done.
    Haven't had one of the simulation based exams yet - but not hearing all that great stuff about them!
