1) Fasten the cables to something solid every 3 feet using Velcro or Zip ties
2) Carefully lay the cables on top of the ceiling tiles so as not to damage them
3) Use something known as J-hooks or cable baskets to support the cables
4) All of the above
3) Use something known as J-hooks or cable baskets to support the cables

True or False
Inductance is a natural consequence that refers to any reduction (loss) in the strength of a signal and it can occur in both optical and electrical signaling.
False

As per the assigned reading once you have each box of 4pair UTP cable in the drop area, what should you do to each box and cable end?
1) Use “Post-it” notes to label the cable end and box of cable
2) Use “Post-it” notes to temporarily label the boxes and a permanent marker to label the cable ends
3) It’s not necessary to label the cables until after they have all been terminated and tested
4) None of the above
2) Use “Post-it” notes to temporarily label the boxes and a permanent marker to label the cable ends
