Broadband Installer Certification Exam Practice Test Questions And Correct Answers (Verified Answers) Plus Rationales 2026 Q&A | Instant Download Pdf

• What is the primary function of a broadband installer?
• Selling cable TV services
• Installing, maintaining, and troubleshooting broadband

connections

• Designing broadband infrastructure
• Supervising customer accounts

Rationale: Broadband installers are responsible for the physical

installation and maintenance of broadband systems, ensuring customers have reliable connectivity.

• Which type of cable is most commonly used for broadband internet

connections? 1 / 4

• Twisted pair
• Fiber optic
• Coaxial cable
• Shielded twisted pair

Rationale: Coaxial cables are widely used in broadband due to their

shielding and ability to carry high-frequency signals.

• What does “DOCSIS” stand for?
• Data Over Cable System Internet Standard
• Data Over Cable Service Interface Specification
• Digital Optical Cable Signal Interface System
• Distributed Optical Cable Service Internet Standard

Rationale: DOCSIS defines standards for data transmission over cable

TV systems.

• What is the primary advantage of fiber optic cable over copper cable?
• Lower cost
• Higher bandwidth and longer transmission distance
• Easier installation
• Lower maintenance requirements

Rationale: Fiber optics offer high bandwidth and can transmit data

over long distances with minimal signal loss.

5. The term “attenuation” refers to:

• Increase in signal power
• Loss of signal strength over distance 2 / 4

• Interference caused by other devices
• Cable impedance

Rationale: Attenuation is the weakening of signal strength as it

travels through a medium.

• Which device connects a customer’s broadband line to the provider’s

network?

• Repeater
• Modem
• Router
• Hub

Rationale: The modem modulates and demodulates signals between

the user’s device and the ISP’s network.

• In a broadband setup, what is the purpose of a router?
• Boosting signal strength
• Distributing network connection to multiple devices
• Modifying signal frequency
• Translating analog signals

Rationale: Routers share a single internet connection among multiple

devices within a network.

• What unit is commonly used to measure signal strength in coaxial

systems?

• Hertz (Hz)
• Decibel millivolts (dBmV) 3 / 4

• Ohms (Ω)
• Amperes (A)

Rationale: Signal strength in cable systems is measured in dBmV to

quantify voltage level in decibels.

• What type of connector is typically used on coaxial cables for

broadband installation?

A. RJ-11

B. RJ-45

• F-type connector
• BNC connector

Rationale: F-type connectors are standard for broadband coaxial

cable terminations.

• What safety precaution should be taken when working near

power lines?

• Wear metal tools
• Ignore minimum distance
• Maintain safe clearance as per OSHA standards
• Use wet gloves

Rationale: OSHA mandates maintaining minimum safe distances

from power lines to prevent electrical hazards.

• Which color code is standard for Cat 5e Ethernet cables

following T568B?

• / 4
