When a Cisco Unified Contact Center Express (UCCX) agent is engaged in a call that is being silently monitored and recorded, there are a total of 4 RTP streams on the network.

The RTP (Real-time Transport Protocol) is used for transmitting audio and video data over IP networks. In a call that is being monitored and recorded, the RTP streams are as follows:

1. Agent RTP stream: This is the RTP stream between the agent's IP phone and the UCCX server.

2. Supervisor RTP stream: This is the RTP stream between the supervisor's IP phone and the UCCX server.

3. Silent Monitoring RTP stream: This is the RTP stream between the UCCX server and the recording server, which is used to capture the audio data for monitoring and recording purposes.

4. Recording RTP stream: This is the RTP stream between the recording server and the storage system, which is used to store the recorded audio data.

Therefore, there are a total of 4 RTP streams on the network when a UCCX agent is engaged in a call that is being silently monitored and recorded. Answer B, "4," is the correct answer.
