10 NCP-ARI Sample Questions with Answers

Sample Question 1 — AI Infrastructure Basics

A deployment team is preparing to install a high-density AI rack in an existing data hall. Which readiness check should be completed before the rack is populated?

  1. A. Confirm the rack color, aisle signage, and label font match the existing data hall standard.
  2. B. Verify available power capacity, cooling capacity, airflow layout, grounding, and redundancy for the planned rack load. (Correct answer)
  3. C. Install the network cables first so actual power draw can be measured under production traffic.
  4. D. Use the average draw from nearby racks because every rack in the same row shares completely identical capacity ratings.

Correct answer: B

Explanation: B is best because Domain 2 focuses on verifying power, cooling, redundancy, and grounding before deployment. A is useful housekeeping but not readiness. C puts installation ahead of capacity validation. D assumes nearby rack load proves this rack is supported.

Sample Question 2 — 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 3 — High-Density Cabling Installation

During a top-feed deployment, the team is ready to connect bundles to several switch line cards in the same rack. Which sequence best follows NVIDIA cabling guidance?

  1. A. Start with the topmost switch or line card, connect every port, then dress all cables once the rack is fully complete.
  2. B. Run the bundle for the topmost switch or line card first, but plug bundles from bottom to top while dressing each U. (Correct answer)
  3. C. Start with the lowest switch or line card because lower ports are harder to reach after cable trays fill.
  4. D. Connect intra-rack bundles first, then use the remaining cable pathways for inter-rack bundles.

Correct answer: B

Explanation: B is best because top-feed bundle placement starts with the topmost switch/line card, while actual plugging proceeds bottom to top with dressing as work progresses. A delays dressing and invites tangles. C applies bottom-feed logic to a top-feed case. D reverses the usual priority of inter-rack bundles before intra-rack bundles.

Sample Question 4 — Pre-Deployment Planning and Site Assessment

A project manager gives the installer a high-level rack list but no port-to-port cabling map. What should happen before cable staging begins?

  1. A. Request or create the physical network documentation that maps source ports, destination ports, cable types, and paths. (Correct answer)
  2. B. Begin staging by rack number and add port details during install, since technicians can reconstruct endpoints from the sequence.
  3. C. Use cable length to infer the source and destination for each connection.
  4. D. Install only intra-rack cabling until the missing details are discovered.

Correct answer: A

Explanation: A is best because pre-deployment planning requires clear physical network documentation before staging. B creates avoidable rework. C guesses topology from length. D starts work without resolving the core documentation gap.

Sample Question 5 — Rack Infrastructure Preparation

A rack design specifies an extra-wide cabinet for cable density, but a standard-width rack is available onsite. What should the installer do?

  1. A. Use the standard rack if all equipment physically fits.
  2. B. Proceed and route excess cable through the rack midpoint.
  3. C. Escalate the mismatch and use the rack type required by the deployment design. (Correct answer)
  4. D. Install only the switches in the standard rack now and defer the servers for later.

Correct answer: C

Explanation: C is best because extra-wide rack requirements are part of the infrastructure design. A ignores cable/service clearances. B violates routing guidance. D creates an unsupported partial layout.

Sample Question 6 — Safety, Standards, and Compliance

Before working near energized rack power infrastructure, which control is most appropriate?

  1. A. Follow site LOTO or energized-work procedures, use required PPE, and verify the work is authorized. (Correct answer)
  2. B. Begin work if the rack door is open and the area is quiet.
  3. C. Wear antistatic gloves as the only required safety control.
  4. D. Ask another available technician to watch the immediate area while the work proceeds without authorization.

Correct answer: A

Explanation: A is best because safety requires approved procedures, PPE, and authorization. B uses informal conditions. C covers ESD only. D adds a watcher but not proper control.

Sample Question 7 — Testing, Verification, and Documentation

After cabling a link, the port remains down. What is the best first verification sequence?

  1. A. Replace the switch immediately, because a properly cabled port should always come up automatically within seconds.
  2. B. Check source/destination mapping, seating, supported cable type, and port status before replacing hardware. (Correct answer)
  3. C. Ignore the link until all other racks are complete.
  4. D. Increase cable bend to improve connector pressure.

Correct answer: B

Explanation: B is best because basic mapping, seating, support, and status checks isolate common causes. A jumps to replacement. C delays a known failure. D can damage the cable.

Sample Question 8 — AI Infrastructure Basics

An AC-powered AI rack has two rPDUs fed from independent power paths. Several servers are connected only to one rPDU. What is the best concern to raise?

  1. A. The rack may look unbalanced, but redundancy is unaffected as long as the total drawn power stays within limits.
  2. B. The rack should use DC distribution because AC racks cannot provide redundancy.
  3. C. A single power-path failure could drop equipment that is not connected across the intended redundant feeds. (Correct answer)
  4. D. The condition only matters after the rack has reached full production utilization.

Correct answer: C

Explanation: C is best because redundancy depends on connecting equipment across independent feeds as designed. A ignores single-path dependency. B falsely claims AC racks cannot be redundant. D delays correction until after risk is already present.

Sample Question 9 — 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 10 — High-Density Cabling Installation

A technician routes most cables for one switch down the right side of the rack because that path is shorter. What is the best correction?

  1. A. Leave the routing as-is if every cable reaches its assigned port and passes continuity.
  2. B. Route all cables down the left side instead so future service work uses a consistent side.
  3. C. Split cables for the same switch U evenly so half route left and half route right. (Correct answer)
  4. D. Bundle the cables more tightly on the right side to reduce the visible cable volume.

Correct answer: C

Explanation: C is best because same-U cable volume should be split 50/50 left and right to balance density and preserve access. A ignores congestion even if links pass. B merely moves the imbalance to the other side. D makes strain and cable deformation more likely.
