Question 6

You’re installing network wiring for a new ethernet network at your company’s main office building. The project specifications call for a category5 UTP network cabling and an 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 five wiring with category three wiring, as they are electrically identical
– No, category five cabling have more twist per instant category three cabling to reduce crosstalk and support higher data rates
– No, the sheet surrounding category five cable is much thicker; creating an extra layer of shielding to reduce crosstalk and support higher data rates
– No category three cabling doesn’t support RJ– 45 connectors
– No, category five cabling uses a thicker copper wiring in category three cable; enabling higher data transmission rates

Answer 6

– No, category five cabling have more twist per instant category three cabling to reduce crosstalk and support higher data rates
