What is the last step in a cable modem's registration?

• A. When the modem successfully retrieves the system configuration settings
• B. When the CMTS receives a registration acknowledge (REG-ACK) message confirming the modem's registration
• C. When the modem establishes a connection with the DHCP server
• D. When the modem uploads its firmware to the network

Answer: (B)

The last step in a cable modem's registration process is when the Cable Modem Termination System (CMTS) receives a registration acknowledge (REG-ACK) message confirming the modem's registration. This step is crucial as it signifies that the modem has successfully completed all the preceding stages, including initial communication, configuring settings, and receiving IP addressing from the DHCP server. Once the modem sends the registration request, and the CMTS processes it, the sendback of the REG-ACK confirms that the modem is fully recognized on the network, allowing it to start transmitting and receiving data. This acknowledgment is essential for establishing a stable and active link between the customer’s modem and the service provider's infrastructure.
