Assignment Help Answers with Step-by-Step Explanation:

- Correct option: a. 250μs

- Explanation: The sampling interval is the reciprocal of the sampling rate. In this case, the sampling rate is 16,000 samples per second, so the sampling interval is 1/16,000 seconds, which is equivalent to 250μs.

- Correct option: d. IANA

- Explanation: The Internet Assigned Numbers Authority (IANA) is responsible for assigning Autonomous System Numbers (ASNs) among other tasks.

- Correct option: c) A and B (Unsolicited downstream and Downstream on demand label)

- Explanation: MPLS uses label allocation schemes, and both unsolicited downstream and downstream on demand label allocation mechanisms are used.

- Correct option: b) Chromatic dispersion

- Explanation: Chromatic dispersion occurs when different colors (wavelengths) of light travel at different speeds in the fiber core.
