Which of the following is a typical symptom of a signal degradation issue?

Frequent service interruptions are a typical symptom of a signal degradation issue because this type of problem often leads to a loss of signal strength or quality, resulting in inconsistent connectivity. When there is degradation, the signals may not be able to maintain a stable connection, causing interruptions in service. This can manifest as dropped calls, video buffering, or issues with data transmission, which are all indicative of a decline in signal integrity.

On the other hand, high-speed internet access, consistent video streaming, and stable telephone service typically reflect a reliable and robust signal. These factors suggest that the signal quality is sufficient for users to enjoy uninterrupted service. Therefore, they do not align with the symptoms of signal degradation, which is characterized by interruptions and instability.
