220-1102 Question 711
Single answerCable managementA technician is re-cabling a small office workstation area that has frequent support calls when users move desks. Several PCs, VoIP phones, monitors, and docking stations are connected under each desk. The current setup has loose cables on the floor, power cords bundled tightly with Ethernet cables, and no labels. The office manager wants to reduce trip hazards and make future troubleshooting faster without replacing all existing equipment. Which action is the BEST first step to improve cable management in this environment?
- A
Bundle all cables together tightly with plastic zip ties so they cannot shift when users move equipment
- B
Label both ends of each cable and separate data cables from power cables using cable ties or Velcro straps and routing paths
- C
Replace all copper Ethernet runs with fiber optic cabling to eliminate interference from nearby power cords
- D
Use extension cords under each desk so devices can be plugged in wherever users need them
Show answer and explanation
Correct answer: B
Explanation
The best answer is to label both ends of each cable and separate power from data cabling using appropriate routing and cable-management materials. In real support environments, this improves maintainability and reduces downtime when equipment is moved or replaced. Common best practices include using reusable Velcro straps instead of overtightened zip ties, keeping cabling organized off the floor when possible, and maintaining clear identification for each connection. These practices are consistent with general structured cabling guidance, manufacturer recommendations for cable handling, and workplace safety expectations aimed at reducing trip hazards and simplifying troubleshooting.
- A. Incorrect.
This is incorrect. While bundling can make cables look neater, tightly binding all cable types together is poor practice. It makes tracing individual connections harder, can strain cables, and mixing power and data in the same tight bundle can increase the chance of electromagnetic interference affecting copper network cables. Zip ties can also be overtightened and damage cable jackets.
- B. Correct.
This is correct. Labeling both ends of cables improves identification during moves, adds, changes, and troubleshooting. Separating power from data cables and using proper routing with reusable ties or Velcro reduces clutter, helps minimize interference concerns, and lowers the risk of accidental disconnection or floor hazards. This is a practical, low-cost first step that aligns with common structured cabling and workplace safety best practices.
- C. Incorrect.
This is incorrect. Replacing all copper with fiber would be expensive and unnecessary for the stated problem. The scenario asks for the best first step without replacing all equipment. Fiber can reduce susceptibility to electromagnetic interference, but the main issues here are poor cable organization, lack of labels, and trip hazards.
- D. Incorrect.
This is incorrect. Adding extension cords under desks can create additional safety and power-distribution issues if not managed properly. It does not address the root cable management problems and may increase clutter and trip hazards. Good cable management focuses on proper routing, securing, and identification rather than adding more unmanaged cabling.
