Which of the following should the technician perform to ensure the hosts on the new switch can communicate with the existing network?

  • A. Replace the new switch with a hub to ensure Layer 1 connectivity on the new network segment.
  • B. Move the straight-through Ethernet cable connecting the switches to the first port on both switches.
  • C. Connect the switches with a cable that has a TIA/EIA 586A wired connector end and a TIA/EIA 586B wired end.

568A on one end and 568B creates a cross over cable. Wouldn't have known this if it wasn't for this question and doing a little research.

The technician is tasked with setting up additional ethernet ports. In adding a new switch, i assume they are attempting to connect the new and the current switches. Crossover cables are used to connect similar devices, so in theory i believe that C is the correct answer if you are trying to pair up both switches to add the additional ethernet ports.

No they don't. Crossover cable reverses all the wires, whereas 568A and 568B differ only in 4 positions 1,2,3 and 6. You can't have a cable with 568A on one end and 568B on the other.

So what is the meaning of a crossover? if it is not connetcting T568A with T568B. Crossover cable connects similar devices.

The cable that reverses all the wires is called a rollover cable. In a rollover cable, the pin order of each wire is reversed. This type of cable is less commonly used these days.
