Sample NV C-42 Video Service Networks Practice Questions

Try these sample questions to test your NV C-42 Video Service Networks exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Under NAC 624.574, what work may a Nevada C-42 contractor perform?
A.Construct, alter, or improve video service networks
B.Install only interior telephone station wiring
C.Build any electrical service of 600 volts or less
D.Install fire-alarm initiating and notification circuits
Explanation: NAC 624.574 grants the C-42 classification for constructing, altering, or improving video service networks. The PSI C-42 outline and the allowed NEC 2017 reference are written around that video-network scope, not general electrical or fire-alarm work.
2Which 2017 NEC article covers community antenna television and radio distribution systems that use coaxial cable?
A.Article 725
B.Article 800
C.Article 810
D.Article 820
Explanation: NEC 2017 Article 820 is Community Antenna Television and Radio Distribution Systems. It governs listed coaxial CATV cable types, grounding of the outer shield, separation from power, and the 50 ft unlisted-entrance rule. Article 810 covers antennas and lead-ins, not the CATV distribution plant.
3Which 2017 NEC article covers communications circuits such as telephone and similar premises communications wiring?
A.Article 640
B.Article 770
C.Article 800
D.Article 820
Explanation: NEC 2017 Article 800 covers communications circuits, including protectors, grounding, listing, and installation of communications wires and cables. Video-network jobs often share pathways and bonding with Article 800 circuits, so the article still appears on a C-42 open-book exam.
4Which 2017 NEC article covers network-powered broadband communications systems that deliver voice, video, or data through a network interface unit powered from the network?
A.Article 725
B.Article 800
C.Article 830
D.Article 840
Explanation: NEC 2017 Article 830 covers network-powered broadband communications systems. The network, not the premises, supplies power to the network interface unit (NIU). Cable types are the BL (low-power) and BM (medium-power) families.
5A fiber drop ends at an optical network terminal that is powered from a premises outlet rather than from the outside plant. Which 2017 NEC article applies?
A.Article 690
B.Article 800 only
C.Article 830
D.Article 840
Explanation: NEC 2017 Article 840 covers premises-powered broadband communications systems. The optical network terminal (ONT) receives signal on optical fiber and takes its operating power from the premises. Article 840 then points to Articles 770, 800, and 820 for the fiber, communications, and coaxial pieces of the installation.
6Which 2017 NEC article covers optical fiber cables and optical fiber raceways used on a video service network?
A.Article 725
B.Article 760
C.Article 770
D.Article 820
Explanation: NEC 2017 Article 770 covers optical fiber cables and raceways, including Types OFNP, OFNR, OFNG, OFN (nonconductive) and OFCP, OFCR, OFCG, OFC (conductive). Hybrid fiber-coax video plants use Article 770 for the fiber and Article 820 for the coaxial plant.
7Under NEC 2017 90.3, how do Chapter 8 communications articles relate to Chapters 1 through 7?
A.Chapter 8 always amends Chapters 1 through 7 the same way Chapter 3 does
B.Chapter 8 is independent of Chapters 1 through 7 except where a Chapter 8 rule specifically references another Code rule
C.Chapters 1 through 7 never apply to any communications installation
D.Chapter 8 applies only to utilities and is outside the NEC for contractors
Explanation: NEC 2017 90.3 states that Chapter 8 covers communications systems and is independent of Chapters 1 through 7 except where a Chapter 8 requirement specifically references a rule from those chapters. That is why 820.24 can send you to 300.4(D) and 300.11, but a Chapter 3 fill table does not automatically rewrite Article 820.
8NEC 2017 820.15 permits coaxial cable to deliver power to equipment directly associated with the radio-frequency distribution system only if the voltage is not over:
A.30 volts
B.50 volts
C.60 volts
D.120 volts
Explanation: NEC 2017 820.15 allows coaxial cable to power RF-distribution equipment such as amplifiers and line extenders if the voltage is not over 60 volts and the current comes from a transformer or other energy-limiting device. Typical CATV network power is 60 VAC on the hardline.
9What must be done with the accessible portion of abandoned coaxial cable under NEC 2017 820.25?
A.It may remain if it is still in good condition
B.It shall be removed unless it is identified for future use with a tag
C.It shall be cut flush and left in the wall cavity
D.It shall be painted red and left in place as a spare
Explanation: NEC 2017 820.25 requires the accessible portion of abandoned coaxial cables to be removed. Cable that is tagged as identified for future use is not abandoned. Concealed cable inside a finished wall or inside a raceway is not treated as accessible.
10When coaxial cable penetrates a fire-resistance-rated wall, floor, or ceiling, NEC 2017 820.26 requires the opening to be:
A.Left open for cable movement
B.Packed only with fiberglass batt insulation
C.Firestopped using an approved method so the fire-resistance rating is maintained
D.Covered with duct tape on both sides
Explanation: NEC 2017 820.26 (and the parallel 800.26 / 770.26 / 300.21 rules) require installations not to substantially increase the spread of fire or products of combustion. Openings around penetrations of fire-resistance-rated assemblies must be firestopped by approved methods listed for the cable and the assembly.
