SCTE Broadband Premises Installer (BPI) Certification Exam |
Complete Study Guide, Practice Questions & Detailed
Solutions (2026/2027)
QUESTION 1
What is the primary purpose of wearing Personal Protective Equipment
(PPE) such as safety glasses and hard hats while performing broadband
installation tasks?
• A. To comply with company dress codes only
• B. To protect the installer from physical hazards such as flying
debris, electrical shocks, and head impacts during construction or
aerial/underground work
• C. To improve cellular reception inside customer homes
• D. To prevent the cable modem from overheating
Correct Answer: B. To protect the installer from physical hazards such as
flying debris, electrical shocks, and head impacts during construction or
aerial/underground work
Detailed Rationale: Safety is paramount in broadband installation. PPE
safeguards installers against environmental and worksite hazards,
including eye injury from wire clippings and head trauma from tools or
overhead drops.
QUESTION 2
,Which type of coaxial cable is most commonly specified for interior
customer drop wiring due to its flexibility and performance
characteristics within home networks?
• A. RG-59
• B. RG-6
• C. RG-11
• D. Hardline 500
Correct Answer: B. RG-6
Detailed Rationale: RG-6 is the industry standard drop cable for interior
and exterior residential runs, offering an optimal balance of flexibility,
attenuation characteristics, and shielding effectiveness compared to
older RG-59.
QUESTION 3
When preparing an RG-6 coaxial cable for a compression F-connector,
what is the standard recommended exposure length for the center
conductor and dielectric/braid?
• A. 1 inch of center conductor and 2 inches of braid
• B. Typically 1/4 inch (6.35 mm) exposed center conductor and 1/4
inch folded back braid/foil, depending on the specific connector
manufacturer specifications
• C. No preparation is required; connectors are self-stripping
• D. 2 inches of center conductor and no braid
,Correct Answer: B. Typically 1/4 inch (6.35 mm) exposed center
conductor and 1/4 inch folded back braid/foil, depending on the
specific connector manufacturer specifications
Detailed Rationale: Correct preparation ensures proper seating of the
connector's internal mandrel against the dielectric and foil, preventing
loose connections, signal leakage, and intermittent service issues.
QUESTION 4
According to the National Electrical Code (NEC) Article 820, what is the
primary purpose of grounding a broadband drop cable at the customer
premises?
• A. To boost the internet download speed
• B. To protect personnel and equipment from hazardous voltages
(such as lightning strikes or power line contacts) by providing a
low-impedance path to earth
• C. To power active amplifiers on the coaxial line
• D. To calibrate television tuners automatically
Correct Answer: B. To protect personnel and equipment from
hazardous voltages (such as lightning strikes or power line contacts) by
providing a low-impedance path to earth
Detailed Rationale: NEC grounding rules dictate that the coaxial cable
shield must be bonded to the electrical service ground to equalize
potentials and prevent dangerous fault currents from entering the
home.
QUESTION 5
, What is the nominal insertion loss (split loss) of an ideal 2-way
resistive/reactive RF splitter across each output port?
• A. Approximately 0 dB
• B. Approximately 3.5 dB to 4.0 dB
• C. Exactly 10 dB
• D. 20 dB
Correct Answer: B. Approximately 3.5 dB to 4.0 dB
Detailed Rationale: Splitting RF energy in half results in a theoretical 3
dB loss, plus an additional fractional dB of insertion loss from internal
circuitry, bringing a standard 2-way splitter loss to roughly 3.5–4 dB per
leg.
QUESTION 6
When using a digital multimeter (DMM) to check for dangerous AC or
DC voltage on a coaxial cable drop before connecting customer
equipment, what setting should the installer select?
• A. Resistance (Ohms)
• B. AC/DC Voltage measurement
• C. Capacitance
• D. Inductance
Correct Answer: B. AC/DC Voltage measurement
Detailed Rationale: Installers must test for stray voltages (such as
hazardous AC voltage from a faulted electrical appliance or power-
