Which of the following is NOT a function of TNCC?

The correct answer highlights that data encryption is not a function associated with TNCC (Transport Network Control Center). TNCC primarily focuses on the management and optimization of transport networks, which includes monitoring network status, managing resources, and optimizing performance to ensure efficient network operations.

Monitoring transport networks involves tracking the health and performance of the network, ensuring that all components are functioning correctly. Network management encompasses a range of activities that deal with configuring, managing, and troubleshooting the network to maintain its integrity and performance. Performance optimization is aimed at enhancing the efficiency and effectiveness of network operations, ensuring that data is transmitted as quickly and reliably as possible.

In contrast, data encryption is typically a function related to information security protocols rather than network management itself. While encryption may be important for securing data transmitted over transport networks, it does not fall under the specific functions of a TNCC focused on operational performance and resource management.
