NCP-ARI Cable Support Systems and Weight Management Sample Questions with Answers

Sample Question 1 — Cable Support Systems and Weight Management

Before a high-density cabling job begins, what should the team orientation plan cover?

  1. A. Only the start time, lunch time, and loading dock location.
  2. B. Only which technician has the fastest cable-pulling experience, so the schedule can be built around that person's throughput.
  3. C. Only the number of links expected to pass validation.
  4. D. The order of work, roles, safety constraints, cable routes, support points, labeling approach, and escalation path. (Correct answer)

Correct answer: D

Explanation: D is best because orientation should align the team on workflow, roles, routes, supports, and quality controls. A is logistics only. B focuses on one person. C is an outcome metric, not a plan.

Sample Question 2 — Cable Support Systems and Weight Management

A large bundle is hanging from switch ports before it reaches the vertical manager. What is the best correction?

  1. A. Leave it if the bundle looks neat.
  2. B. Add approved support so cable weight is carried by cable-management hardware, not ports or transceivers. (Correct answer)
  3. C. Tighten the bundle directly to the nearest transceiver handles so the connectors themselves carry the cable weight.
  4. D. Reduce labels so the bundle weighs less.

Correct answer: B

Explanation: B is best because weight must be supported by rack/cable hardware, not connectors. A ignores strain. C worsens port stress. D has no meaningful effect on bundle weight.

Sample Question 3 — Cable Support Systems and Weight Management

Which overhead support issue matters most for ultra-high-density cabling?

  1. A. Whether trays or ladder racks are rated, sized, and routed for the planned cable volume and weight. (Correct answer)
  2. B. Whether the overhead path matches the rack row color, since a consistent finish confirms the tray's load rating.
  3. C. Whether fiber and copper labels use the same font.
  4. D. Whether cables can rest temporarily on ceiling tiles.

Correct answer: A

Explanation: A is best because overhead systems must support both volume and weight. B and C are visual details. D is not an approved support method.

Sample Question 4 — Cable Support Systems and Weight Management

A technician stores excess slack in a tight coil on top of a rack. What is the concern?

  1. A. Slack coils on top of the rack are always preferred because they look organized.
  2. B. Slack should always be stored in the rack midpoint instead.
  3. C. Coils change multimode fiber into single-mode behavior.
  4. D. Tight coils can violate bend radius and add unsupported weight or congestion. (Correct answer)

Correct answer: D

Explanation: D is best because slack must be managed without tight bends, strain, or congestion. A values appearance over limits. B uses a poor service path. C is technically false.

Sample Question 5 — Cable Support Systems and Weight Management

A cable tray is approved for existing load, but the new AI deployment will double the bundle volume. What should happen?

  1. A. Install the new bundles because the tray is already approved for its current load rating.
  2. B. Verify tray capacity, fill, support spacing, and route before adding the new bundle load. (Correct answer)
  3. C. Compress existing bundles to create more space.
  4. D. Move heavier bundles onto switch handles.

Correct answer: B

Explanation: B is best because additional weight and fill must be assessed before use. A assumes prior approval covers new load. C risks cable damage. D transfers load to unsupported hardware.

Sample Question 6 — Cable Support Systems and Weight Management

Which practice best prevents damage when pulling a heavy bundle through overhead support?

  1. A. Let the bundle hang until both ends are plugged in.
  2. B. Pull harder at the destination end to reduce installation time, since a faster pull minimizes how long the jacket contacts the tray.
  3. C. Use enough technicians and supports to control weight, avoid sharp edges, and maintain bend radius throughout the path. (Correct answer)
  4. D. Tie the bundle tightly every few inches before pulling.

Correct answer: C

Explanation: C is best because heavy bundle handling needs controlled support and bend-radius protection. A leaves unsupported weight. B increases damage risk. D can flatten or constrain cables during placement.

Sample Question 7 — Cable Support Systems and Weight Management

A bundle is supported only at the start and end of a long overhead run. What is the risk?

  1. A. Excess sag and concentrated load can strain cables and support points. (Correct answer)
  2. B. The link speed will automatically increase because the cable is straighter.
  3. C. Documentation cannot be completed until the sag is measured.
  4. D. Only copper cables are affected; fiber is immune to sag.

Correct answer: A

Explanation: A is best because long unsupported spans create sag and concentrated loads. B is false. C is not the primary risk. D incorrectly excludes fiber.

Sample Question 8 — Cable Support Systems and Weight Management

A technician proposes using plastic zip ties to hold a dense optical bundle tightly in place. What is the best response?

  1. A. Use zip ties only on fiber because fiber jackets are stronger and resist the compression a tight cinch applies.
  2. B. Use approved soft fasteners or supports that secure the bundle without crushing or deforming cables. (Correct answer)
  3. C. Use zip ties at every connector so strain is controlled.
  4. D. Use no support at all until after link validation.

Correct answer: B

Explanation: B is best because dense bundles need support without jacket deformation. A is an unsafe assumption. C concentrates stress near connectors. D delays required support.
