These 10 free BPT questions are organized by exam domain, so you can see how each part of the Broadband Premises Technician blueprint is tested. Reveal the answer and explanation under each question.

Domain 1: Broadband Premises Installation - Fundamentals

Question 1

During cable-modem registration, after the modem obtains its IP address from the DHCP server, which step normally occurs NEXT?

  1. It requests the time of day (ToD)
  2. It begins the ranging process
  3. It downloads its configuration file via TFTP
  4. It scans for a downstream channel
Show answer & explanation

Correct answer: A - It requests the time of day (ToD)

Domain 2: Broadband Premises Troubleshooting

Question 2

A signal entering a 2-way splitter measures 0 dBmV. Ignoring cable loss, what is the approximate level at each output port?

  1. 0 dBmV
  2. -3.5 dBmV
  3. -7 dBmV
  4. +3.5 dBmV
Show answer & explanation

Correct answer: B - -3.5 dBmV

Question 3

Before connecting a customer's equipment, a technician places a digital multimeter in voltage mode across the chassis and the ground block. What hazard is being checked for?

  1. A short between the cable shield and the center conductor
  2. Excessive downstream RF level reaching the equipment port
  3. A stray hot-chassis voltage caused by improper grounding
  4. An open conductor somewhere along the length of the drop
Show answer & explanation

Correct answer: C - A stray hot-chassis voltage caused by improper grounding

Domain 3: Safety

Question 4

Per the National Electrical Code, the bonding conductor used to ground a coaxial drop shield must be:

  1. No smaller than 14 AWG copper
  2. No smaller than 10 AWG copper
  3. Exactly 6 AWG copper in all installations
  4. Sized to match the center conductor gauge
Show answer & explanation

Correct answer: A - No smaller than 14 AWG copper

Question 5

A drop run of roughly 300 feet is causing low signal at a customer's home. Which coaxial cable should the technician use to MINIMIZE signal loss over this distance?

  1. RG-59
  2. RG-6
  3. Cat 6
  4. RG-11
Show answer & explanation

Correct answer: D - RG-11

Domain 4: Customer Service

Question 6

A customer reports intermittent internet dropouts. At the ground block the downstream level reads a healthy +2 dBmV, but the cable modem reports an upstream transmit level of +56 dBmV. What does this reading MOST likely indicate?

  1. The downstream signal is too hot and needs an attenuator
  2. The modem firmware needs to be updated
  3. Excessive loss between the modem and the node
  4. Normal operation for a bonded DOCSIS channel
Show answer & explanation

Correct answer: C - Excessive loss between the modem and the node

Question 7

While investigating upstream data errors, a technician finds a loose connector on a splitter that has allowed an over-the-air signal to enter the cable. This impairment is BEST classified as:

  1. Egress
  2. Tilt
  3. Group delay
  4. Ingress
Show answer & explanation

Correct answer: D - Ingress

Question 8

A customer's digital channels show blocking and pixelation, yet the downstream RF level is within spec. Which measurement is the technician MOST likely to find degraded?

  1. Modulation Error Ratio (MER)
  2. The hum modulation level on the affected carrier
  3. The center carrier frequency of the affected channel
  4. The width of the upstream channel used by the modem
Show answer & explanation

Correct answer: A - Modulation Error Ratio (MER)

Domain 5: Understanding Cable Technology

Question 9

Cable signal leakage (egress) into the over-the-air spectrum is primarily a concern because it can interfere with which protected service, and is regulated under which authority?

  1. Local AM radio, regulated by the franchise authority
  2. Aeronautical communications, regulated by the FCC
  3. Cellular service, regulated by the NEC
  4. Emergency sirens, regulated by OSHA
Show answer & explanation

Correct answer: B - Aeronautical communications, regulated by the FCC

Question 10

A technician must set up an extension ladder near an energized power service drop. Which ladder is the correct choice?

  1. An aluminum ladder, for its light weight
  2. A fiberglass ladder
  3. Whichever ladder is closest in the truck
  4. A wooden ladder, as long as it is dry
Show answer & explanation

Correct answer: B - A fiberglass ladder
