No other user have complained of a problem and you suspect that faulty network cabling might be to blame. Which of the following troubleshooting steps are you most likely to perform first?
  • No. You should purchase patch cables that use MTRJ connectors.
  • The cable is functioning correctly & This is a crossover cable.
  • No you shouldn't use multi-mode patch cables with single mode GBIC modules.
  • Use a cable tester to test the cable between the computer system and the network switch.

You are building a new network for a small startup financial services company. Security is paramount so each organization within the company will have their own network segments separated by routers. Funds are limited and you have been asked to keep costs to a minimum. You have acquired a used fiber optic switch and want to use it to create a fiber optic backbone that interconnects all of the routers. You purchased several used multi-mode GBIC modules on Ebay that you will install in each router and allow them to connect to the switch. Both the switch and the GBIC modules use MTRJ connectors. You purchased several used 1-meter multi-mode patch cables from Amazon. But when they arrived, you noticed that they use LC connectors. Fortunately with some force you found that you are able to get the LC connectors on the cables to lock into the MTRJ connectors on the GBIC modules and on the switch. Will this implementation work?
  • The cable is functioning correctly & This is a crossover cable.
  • Use a cable tester to test the cable between the computer system and the network switch.
  • No. You should purchase patch cables that use MTRJ connectors.
  • No you shouldn't use multi-mode patch cables with single mode GBIC modules.
