    • Permanent walls

    • Access floring

    Correct Answer(s)
    A. Building colums
    A. Permanent walls
    Explanation
    MUTOA, or Main Unit Telecommunication Outlet Assembly, must be located in fully accessible and permanent locations to ensure efficient and reliable telecommunication connections. Building columns and permanent walls provide stable and secure positions for MUTOA installation, allowing easy access for maintenance and repairs. These locations also protect the MUTOA from potential damage or interference. Ceiling spaces and access flooring may not be suitable as they might not provide the necessary stability and accessibility required for MUTOA placement.

    When telecommunications cabling pathways run parallel to electrical pathways, the recommendation is a minimum of ________ separation?

    • 75 mm (3 in)

    • 100 mm (4 in)

    • 51 mm ( 2 in)

    • 25 mm ( 1 in)

    Correct Answer
    A. 51 mm ( 2 in)
    Explanation
    When telecommunications cabling pathways run parallel to electrical pathways, it is recommended to have a minimum separation of 51 mm (2 in). This separation is necessary to prevent interference and crosstalk between the telecommunications and electrical cables. By maintaining this distance, the risk of signal degradation and data loss is minimized, ensuring reliable communication and efficient operation of both systems.

    The cross-sectional area of the straight section of a furniture pathway for telecommunications cabling must be at least___________

    • 1.5 in sq

    • 1 in sq

    • 2.5 in sq

    • 3 in sq

    Correct Answer
    A. 1.5 in sq
    Explanation
    The cross-sectional area of the straight section of a furniture pathway for telecommunications cabling must be at least 1.5 in sq. This ensures that there is enough space for the cables to pass through without any obstruction or damage. A larger cross-sectional area allows for better cable management and reduces the risk of overheating or interference. Therefore, 1.5 in sq is the minimum requirement for the furniture pathway to accommodate the telecommunications cabling effectively.

    Rate this question:

  • 49. 

    Furniture and horizontal pathway capacity should not exceed what percent of the pathway cross section?

    • 20%

    • 30%

    • 60%

    • 40%

    Correct Answer
    A. 40%
    Explanation
    The correct answer is 40%. This means that the combined capacity of furniture and horizontal pathways should not exceed 40% of the pathway cross section. This is important to ensure that there is enough space for people to move comfortably and safely through the pathway without any obstructions or congestion. If the capacity exceeds 40%, it could lead to difficulties in navigation and potential safety hazards.
