  4. mario rossi says:

    what are the right answers in the comment? they are not explained..

  5. helloworld says:

    A customer installs a wireless access point at home in the closet next to the kitchen. The customer mentions that the wireless communication performance seems degraded when the cordless phone or the microwave oven is in use. What is the possible reason for this degradation?

    • helloworld says:

      The access point is close to walls.
      The cordless phone joins the WLAN and shares the available bandwidth.
      The wireless signal is in the same radio frequency range as the household devices are in.
      The access point is on the same electrical circuit as the phone base unit and microwave oven are.
      The surge of electricity when a microwave oven is in use disrupts the operation of the access point.

  6. Jemma Wright says:

    Can you update this? I need to find all the 2012 exams but i cant find them does anyone know a link?

    So to recap. Most of the questions in the beginning are still being used. Only 5 questions are new.

  8. is This updated? please very fast answer, i write a exam tomorrow :(

  9. What is the right answer to #5 in the comments? Its not clear… “Refer to the exhibit. An IsP donates some decommissioned…RTA and RTB?”

    Is it “coax cable” ?
    Or “rollover cable” ?
    or crossover cable ?
    or straight-through cable?

    Which one is it?

  10. What is a purpose of the physical layer in data communication?
    to wrap data packets into frames
    to make sure that MAC addresses are unique in each frame
    to control the access sequence of frames to the transmission media
