Question 1 of 355
Which characteristic is an advantage of copper based media over optical fiber cable?
    Correct Answer: C

    Copper-based media have the advantage of being able to handle analog signals, which is not possible with optical fiber cables that are designed for digital data transmission. This makes copper cables suitable for scenarios where analog signal transmission is required.

Question 2 of 355
Which is an advantage of stranded conductors over solid conductors?
    Correct Answer: D

    Stranded conductors are made up of multiple small strands, making them more flexible compared to solid conductors. This flexibility allows for easier bending and manipulation during installation, which is particularly useful in applications where the conductor needs to navigate through tight spaces or around obstacles.

Question 3 of 355
Composite conductors, although not generally recommended, may be used in special circumstances because they provide all of the following advantages
EXCEPT:
    Correct Answer: A

    Composite conductors are noted for being lightweight, inexpensive, easy to produce, and easily embedded into other materials. However, they do not have good digital transmission characteristics, making this the correct answer when identifying the exception among the advantages they provide.

Question 4 of 355
Which electrical characteristic is displayed with the correct preferred value?
    Correct Answer: B

    Dielectric strength should have a high value, as it represents the material's ability to withstand electric stress without breaking down. A high dielectric strength means the material can handle higher voltages, which is desirable.

Question 5 of 355
If the input signal power to a communication system is 1 W and the output power is 1 mW, the system attenuation is:
    Correct Answer: C

    The attenuation of a system is calculated using the formula: Attenuation (dB) = 10 * log10(Pi / Po), where Pi is the input power and Po is the output power. Given Pi is 1 W and Po is 1 mW (which is 0.001 W), the calculation becomes: Attenuation = 10 * log10(1 / 0.001) = 10 * log10(1000) = 10 * 3 = 30 dB.
