HPE Aruba Certified Network Security Professional (ACNSP) — Question 4

What is the process where a compute device converts logical data bits into the correct physical representation depending on the media?

Answer options

• A. Demodulation
• B. Modulation
• C. Propagation
• D. Encapsulation

Correct answer: B

Explanation

The correct answer is B, Modulation, as it involves converting digital data into analog signals suitable for transmission over various media. A is incorrect because Demodulation is the reverse process of recovering the original data from the modulated signal. C, Propagation, refers to the transmission of signals through a medium, while D, Encapsulation, pertains to the packaging of data into a format for transmission, not the conversion of data bits.
