1 correct answerThe correct answer is B. 10 m (33').
Explanation:
In conduit installation, there is a common rule about the maximum number of 90-degree bends allowed in a conduit run before a pull point or junction box is required. Normally, a conduit run should not contain more than 360 degrees of total bends between pull points. That means you can have four 90-degree bends total.
However, the question is asking about a third 90-degree bend being permitted only if the run does not exceed a certain length. This reflects the practical limitation that long conduit runs with multiple bends become difficult to pull conductors through.
Why B is correct:
- A third 90-degree bend is sometimes allowed if the run is relatively short.
- The specified limit is 10 m, or 33 feet.
- If the run exceeds that length, additional bends would make conductor installation too difficult and would require a pull point.
Why the other options are incorrect:
- A. 5 m (16.5') is too short and not the recognized limit here.
- C. 15 m (50') is longer than the permitted threshold.
- D. 30 m (100') is far too long for allowing a third 90-degree bend without an intermediate access point.
In short, the third 90-degree bend may be permitted only when the conduit run does not exceed 10 m (33').

A.Impedance
B.Capacitance
C.Inductance
D.Resistance
Check the image below to see the right answer:Select the answer
1 correct answerThe correct answer is C. Inductance.
Explanation:
Inductance is the property of an electromagnetic field around a conductor that opposes changes in current flow. When current through a conductor changes, the magnetic field around it changes too, and this changing magnetic field induces a voltage that resists the change in current. This behavior is described by Lenz’s law.
Why the other options are incorrect:
A. Impedance
Impedance is the total opposition a circuit offers to alternating current. It includes resistance and reactance, so it is broader than the specific property described in the question.
B. Capacitance
Capacitance is the ability to store electric charge, not the property that opposes changes in current.
D. Resistance
Resistance opposes the flow of current, but it does not specifically refer to the electromagnetic effect that resists changes in current.
So the property described is inductance.

D.OFNP
Check the image below to see the right answer:Select the answer
1 correct answerThe correct answer is A. OFNG
Explanation:
This question is asking about the marking used for non-conductive optical fiber general-purpose cables.
In optical fiber cable classification:
- OF stands for Optical Fiber
- N means Non-conductive
- G means General-purpose
So OFNG specifically refers to a non-conductive, general-purpose optical fiber cable.
Why the other options are incorrect:
- OFCR means Optical Fiber Conductive Riser
- OFCP means Optical Fiber Conductive Plenum
- OFNP means Optical Fiber Non-conductive Plenum
These are different cable ratings used for different installation environments, such as plenum spaces or riser shafts. The key detail in the question is "non-conductive" and "general-purpose," which matches OFNG exactly.
Therefore, the correct answer is A. OFNG

D.SMopticalfiber
Check the image below to see the right answer:Select the answer
1 correct answerThe correct answer is A. MM with a 100 um core diameter.
Explanation:
Optical fiber cables are commonly color-coded to help identify the type of fiber they contain. In standard fiber color coding, an orange outer sheath typically indicates multimode fiber.
Here is how the options compare:
A. MM with a 100 um core diameter
This is correct. Orange is commonly used for multimode fiber cables, especially those with a 100 um core diameter.
B. Dispersion-shifted SM optical fiber
This is incorrect. Single-mode fibers are usually color-coded differently, often yellow for standard single-mode fiber.
C. Polarization maintain SM optical fiber
This is incorrect. Polarization-maintaining fibers typically have special color coding, but not orange.
D. SM optical fiber
This is incorrect. Standard single-mode fiber is generally not orange; yellow is the usual color.
Why orange is used:
Orange is the conventional sheath color for multimode fiber because it provides a quick visual distinction from single-mode fiber in installations and patch panels. This helps technicians avoid mistakes when connecting or troubleshooting fiber links.
So the best answer is A, since orange outer sheaths are associated with multimode fiber, including the type described with a 100 um core diameter.

Check the image below to see the right answer:Select the answer
1 correct answerThe correct answer is D. Takes up less space within the equipment room.
Explanation:
Wall-mounted racks and cabinets are designed to be attached to a wall rather than occupying floor space like traditional equipment racks. Their main advantage is that they free up valuable floor area, making them especially useful in smaller rooms or locations where space is limited.
Why the other options are not correct:
A. Provides equipment with a higher level of protection
Wall-mounted racks may offer some protection, but their primary purpose is not enhanced security or protection. They are mainly used for space savings and organization.
B. Allows for the equipment to be easily rearranged
Traditional racks are often better for rearranging equipment because they typically provide more flexible access and capacity. Wall-mounted units are usually more fixed in position.
C. Optimizes airflow within the equipment room
While airflow can be a factor in equipment installation, wall-mounted racks are not mainly chosen for this reason. Their key benefit is saving floor space.
In summary, the primary benefit of wall-mounted racks and cabinets is that they take up less space in the equipment room.

1 correct answerThe correct answer is D. International Organization for Standardization (ISO) and International Electrotechnical Commission (IEC).
Explanation:
Worldwide standardization of telecommunications cabling is jointly overseen by ISO and IEC. These two international standards organizations work together to develop and publish global cabling standards used across countries and industries. A well-known example is the ISO/IEC 11801 standard, which covers generic cabling for customer premises.
Why the other options are incorrect:
A. Alliance for Telecommunications Industry Solutions (ATIS) and Society for Cable Telecommunications Engineers (SCTE)
These organizations are involved in telecommunications and cable-related standards in North America, but they do not jointly oversee worldwide standardization of telecommunications cabling.
B. National Electrical Contractors Association (NECA) and National Fire Protection Association (NFPA)
These groups are important in electrical installation and safety standards, but they are not the global authorities for telecommunications cabling standardization.
C. Comite Europeen de Normalisation Electrotechnique (CENELEC) and Electronic Industries Association (EIA)
These organizations have influence in regional or industry standards, but they do not jointly manage worldwide cabling standards. EIA is historically significant in cabling standards, especially in the U.S., but the global standard-setting bodies are ISO and IEC.
Why D is correct:
ISO and IEC are the two international bodies responsible for creating global standards that ensure compatibility, interoperability, and consistency in telecommunications cabling systems around the world. Their joint standards are widely adopted by manufacturers, designers, and installers internationally.
If you want, I can also explain the difference between ISO/IEC, TIA/EIA, and CENELEC cabling standards.
