SIP ARP Question 11 of 43 You are installing networking wiring for a new Ethernet network at your company's main office building. The project specifications call for Category 5 UTP network cabling and RJ 45 wall jacks. Near the end of the project, you run out of wire before the last few runs are complete. You have a spool of Category 3 network cable in storage. Upon investigation, it appears very similar to Category 5 wiring. Should you substitute Category 3 cabling for Category 5 cabling to finish the project? Yes, you can substitute Category 5 wiring with Category 3 wiring, as they are electrically identical. No, the sheath surrounding Category 5 cable is much thicker; creating an extra layer of shielding to reduce cross talk and support higher data rates. No, Category 5 cabling has more twists per inch than Category 3 cabling to reduce cross talk and support higher data rates. No, Category 5 cabling uses a thicker copper wire than Category 3 cable; enabling higher data transmission rates. No, Category 3 cabling doesn't support RJ 45 connectors.
