Which of the following is NOT a method to monitor a net?

• A. Guard
• B. Copy
• C. Listen
• D. Maintain silence

Answer: (D)

Monitoring a radio net requires active engagement with the traffic so you can receive, record, and relay messages as needed. Listening is the core action you perform to hear what's being transmitted on the net. Copying is taking down those transmissions accurately so nothing is lost or misinterpreted when you relay or log them. Guarding means staying on the assigned net, being ready to receive, and ensuring you can forward or respond as directed, while keeping the net orderly and on the correct frequency. Maintaining silence, by contrast, isn’t about monitoring at all; it means not transmitting and often not actively listening, which prevents you from receiving or participating in net traffic. So maintaining silence isn’t a method to monitor a net.
