Multiple choice

While monitoring traffic on a cable network, a technician notes that data is being transmitted at 38 MHz. Which statement describes the situation observed by the technician?

  1. Data is being transmitted from the subscriber to the headend.

  2. Data is flowing downstream.

  3. Cable television transmissions are interfering with voice and data transmissions.

  4. The system is experiencing congestion in the lower frequency ranges.

B Correct answer
Explanation

In cable networks, downstream data (from headend to subscriber) typically operates in higher frequency ranges (38 MHz is within the downstream range). Upstream data (subscriber to headend) uses lower frequencies (5-42 MHz). 38 MHz is in the downstream direction. Cable TV interference would cause signal quality issues, not just frequency observations, and congestion doesn't explain the specific frequency.
