Explanation
If a communications cable is not terminated to any equipment and is not identified for future use with a tag, it is considered abandoned. This means that it is no longer in use or intended for use in the future.
3.
A nonmetallic raceway placed within a larger raceway is defined as ____.
Correct Answer
B. B. innerduct
Explanation
An innerduct is a nonmetallic raceway that is placed within a larger raceway. It is used to provide additional protection and organization for cables or wires within the larger raceway. This can help prevent damage and interference between different cables or wires.

Cables installed parallel to framing members or furring strips must be protected from damage by either installing the wiring method so it isn’t less than 1¼ in. from the nearest edge of the framing member or furring strips or installing a 1⁄16-in.-thick steel plate or the equivalent.
Correct Answer
A. A. True
Explanation
Cables installed parallel to framing members or furring strips can be easily damaged if not properly protected. To prevent damage, the wiring method must be installed at a distance of at least 1¼ inches from the nearest edge of the framing member or furring strips. Alternatively, a 1/16-inch-thick steel plate or an equivalent protective measure can be used. Therefore, the statement "Cables installed parallel to framing members or furring strips must be protected from damage by either installing the wiring method so it isn’t less than 1¼ in. from the nearest edge of the framing member or furring strips or installing a 1/16-in.-thick steel plate or the equivalent" is true.
6.
Cable ties are never permitted in a plenum ceiling.
Correct Answer
A. A. True
Explanation
Cable ties are not permitted in a plenum ceiling because plenum ceilings are spaces used for air circulation in buildings. Using cable ties in these spaces can pose a fire hazard as they can restrict airflow and potentially cause overheating. Therefore, it is true that cable ties are never permitted in a plenum ceiling.
7.
Cables installed in concealed raceways aren’t considered ____; therefore, they’re not required to be removed.
Correct Answer
A. A. accessible
Explanation
Cables installed in concealed raceways are not considered accessible because they are hidden or enclosed, making them difficult to reach or interact with. Therefore, they are not required to be removed.
8.
Openings in fire-rated walls, floors and ceilings must be firestopped ____.
Correct Answer
C. C. using approved methods to maintain the fire resistance rating
Explanation
C – 800.26
9.
The scope of Article 800 covers ____.
Correct Answer
D. D. communications circuits and equipment
Explanation
The correct answer is d. communications circuits and equipment. This means that Article 800 of the given scope covers the regulations and guidelines regarding the installation, maintenance, and safety standards for communications circuits and equipment. It does not include fire alarm circuits and wiring, wiring methods and materials, or network powered broadband communications systems.

Optical fiber cables shall be permitted in the same raceway with which of the following?
Correct Answer
A. A. Nonconductive and conductive optical fiber cables in compliance with Parts I & V of Article 770
Explanation
Optical fiber cables are allowed to be installed in the same raceway as nonconductive and conductive optical fiber cables, as long as they comply with the regulations outlined in Parts I & V of Article 770. This means that optical fiber cables can be installed together with other optical fiber cables, as long as they meet the necessary safety requirements specified in the mentioned article.

Communications equipment shall be listed as being suitable for electrical connection ____.
Correct Answer
D. D. to a communications network
Explanation
D – 800.170
13.
Conductors in communications cables, other than in a coaxial cable shall be ____.
Correct Answer
A. A. copper
Explanation
Conductors in communications cables, other than in a coaxial cable, are typically made of copper. Copper is a widely used material for conductors due to its excellent conductivity and resistance to corrosion. It allows for efficient transmission of electrical signals in communication systems. Other options such as minimum AWG, voltage rating, and temperature rating are not specific to the material used for the conductors and do not accurately describe the requirement for conductors in communications cables.
14.
According to Article 800, the provisions of 300.22(A) ____.
Correct Answer
A. A. apply
Explanation
According to Article 800, the provisions of 300.22(A) apply. This means that the rules and regulations stated in 300.22(A) are relevant and must be followed in relation to Article 800. The specific details of what these provisions entail are not mentioned, but it is clear that they are applicable in this context.
15.
Cable ties intended for use in other space used for environment air shall be listed as having low smoke and heat release properties and are defined as ____.
Correct Answer
B. B. plenum grade cable ties
Explanation
Plenum grade cable ties are specifically designed for use in spaces used for air circulation, such as plenum spaces. These spaces require cable ties that have low smoke and heat release properties in order to minimize the risk of fire and smoke spreading through the ventilation system. Therefore, plenum grade cable ties are the appropriate choice for cable management in these environments.
16.
Where bonding or grounding is required, devices used to connect a shield, a sheath or non-current-carrying metallic members of a cable to a bonding conductor or ____ shall be listed or be part of listed equipment.
Correct Answer
